|
* This object provides a utility for producing rich Error messages within |
|
* Angular. It can be called as follows: |
|
* |
|
* var exampleMinErr = minErr('example'); |
|
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar); |
|
* |
|
* The above creates an instance of minErr in the example namespace. The |
|
* resulting error will have a namespaced error code of example.one. The |
|
* resulting error will replace {0} with the value of foo, and {1} with the |
|
* value of bar. The object is not restricted in the number of arguments it can |
|
* take. |
|
* |
|
* If fewer arguments are specified than necessary for interpolation, the extra |
|
* interpolation markers will be preserved in the final string. |
|
* |
|
* Since data will be parsed statically during a build step, some restrictions |
|
* are applied with respect to how minErr instances are created and called. |
|
* Instances should have names of the form namespaceMinErr for a minErr created |
|
* using minErr('namespace') . Error codes, namespaces and template strings |
|
* should all be static strings, not variables or general expressions. |
|
* |
|
* @param {string} module The namespace to use for the new minErr instance. |
|
* @param {function} ErrorConstructor Custom error constructor to be instantiated when returning |
|
* error from returned function, for cases when a particular type of error is useful. |
|
* @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance |

|
* @param {angular.Module} ngApp an optional application |
|
* {@link angular.module module} name to load. |
|
* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be |
|
* created in "strict-di" mode. This means that the application will fail to invoke functions which |
|
* do not use explicit function annotation (and are thus unsuitable for minification), as described |
|
* in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in |
|
* tracking down the root of these bugs. |
|
* |
|
* @description |
|
* |
|
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive |
|
* designates the **root element** of the application and is typically placed near the root element |
|
* of the page - e.g. on the `<body>` or `<html>` tags. |
|
* |
|
* There are a few things to keep in mind when using `ngApp`: |
|
* - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp` |
|
* found in the document will be used to define the root element to auto-bootstrap as an |
|
* application. To run multiple applications in an HTML document you must manually bootstrap them using |
|
* {@link angular.bootstrap} instead. |
|
* - AngularJS applications cannot be nested within each other. |
|
* - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`. |
|
* This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and |
|
* {@link ngRoute.ngView `ngView`}. |
|
* Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector}, |
|
* causing animations to stop working and making the injector inaccessible from outside the app. |
|
* |
|
* You can specify an **AngularJS module** to be used as the root module for the application. This |
|
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It |
|
* should contain the application code needed or have dependencies on other modules that will |
|
* contain the code. See {@link angular.module} for more information. |
|
* |
|
* In the example below if the `ngApp` directive were not placed on the `html` element then the |
|
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}` |
|
* would not be resolved to `3`. |
|
* |
|
* `ngApp` is the easiest, and most common way to bootstrap an application. |
|
* |
|
<example module="ngAppDemo"> |
|
<file name="index.html"> |
|
<div ng-controller="ngAppDemoController"> |
|
I can add: {{a}} + {{b}} = {{ a+b }} |
|

|
</file> |
|
<file name="script.js"> |
|
angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) { |
|
$scope.a = 1; |
|
$scope.b = 2; |
|
}); |
|
</file> |
|
</example> |
|
* |
|
* Using `ngStrictDi`, you would see something like this: |
|
* |
|
<example ng-app-included="true"> |
|
<file name="index.html"> |
|
<div ng-app="ngAppStrictDemo" ng-strict-di> |
|
<div ng-controller="GoodController1"> |
|
I can add: {{a}} + {{b}} = {{ a+b }} |
|
|
|
<p>This renders because the controller does not fail to |
|
instantiate, by using explicit annotation style (see |
|
script.js for details) |

<div ng-controller="GoodController2"> |

|
* |
|
* The `angular.module` is a global place for creating, registering and retrieving Angular |
|
* modules. |
|
* All modules (angular core or 3rd party) that should be available to an application must be |
|
* registered using this mechanism. |
|
* |
|
* Passing one argument retrieves an existing {@link angular.Module}, |
|
* whereas passing more than one argument creates a new {@link angular.Module} |
|
* |
|
* |
|
* # Module |
|
* |
|
* A module is a collection of services, directives, controllers, filters, and configuration information. |
|
* `angular.module` is used to configure the {@link auto.$injector $injector}. |
|
* |
|
* ```js |
|
* // Create a new module |
|
* var myModule = angular.module('myModule', []); |
|
* |
|
* // register a new service |
|
* myModule.value('appName', 'MyCoolApp'); |
|
* |
|
* // configure existing services inside initialization blocks. |
|
* myModule.config(['$locationProvider', function($locationProvider) { |
|
* // Configure existing providers |
|
* $locationProvider.hashPrefix('!'); |
|
* }]); |
|
* ``` |
|
* |
|
* Then you can create an injector and load your modules like this: |
|
* |
|
* ```js |
|
* var injector = angular.injector(['ng', 'myModule']) |
|
* ``` |
|
* |
|
* However it's more likely that you'll just use |
|
* {@link ng.directive:ngApp ngApp} or |
|
* {@link angular.bootstrap} to simplify this process for you. |
|
* |
|
* @param {!string} name The name of the module to create or retrieve. |
|
* @param {!Array.<string>=} requires If specified then new module is being created. If |
|
* unspecified then the module is being retrieved for further configuration. |
|
* @param {Function=} configFn Optional configuration function for the module. Same as |
|
* {@link angular.Module#config Module#config()}. |
|
* @returns {angular.Module} new module with the {@link angular.Module} api. |

/** |
|
* @ngdoc function |
|
* @name angular.element |
|
* @module ng |
|
* @kind function |
|
* |
|
* @description |
|
* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element. |
|
* |
|
* If jQuery is available, `angular.element` is an alias for the |
|
* [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element` |
|
* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**. |
|
* |
|
* jqLite is a tiny, API-compatible subset of jQuery that allows |
|
* Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most |
|
* commonly needed functionality with the goal of having a very small footprint. |
|
* |
|
* To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the |
|
* {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a |
|
* specific version of jQuery if multiple versions exist on the page. |
|
* |
|
* <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or |
|
* jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div> |
|
* |
|
* <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements |
|
* by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)` |
|
* or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div> |
|
* |
|
* ## Angular's jqLite |
|
* jqLite provides only the following jQuery methods: |
|
* |
|
* - [`addClass()`](http://api.jquery.com/addClass/) |
|
* - [`after()`](http://api.jquery.com/after/) |
|
* - [`append()`](http://api.jquery.com/append/) |
|
* - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters |
|
* - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData |
|
* - [`children()`](http://api.jquery.com/children/) - Does not support selectors |
|
* - [`clone()`](http://api.jquery.com/clone/) |
|
* - [`contents()`](http://api.jquery.com/contents/) |
|
* - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. |
|
* As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing. |
|
* - [`data()`](http://api.jquery.com/data/) |
|
* - [`detach()`](http://api.jquery.com/detach/) |
|
* - [`empty()`](http://api.jquery.com/empty/) |
|
* - [`eq()`](http://api.jquery.com/eq/) |
|
* - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name |
|
* - [`hasClass()`](http://api.jquery.com/hasClass/) |
|
* - [`html()`](http://api.jquery.com/html/) |
|
* - [`next()`](http://api.jquery.com/next/) - Does not support selectors |
|
* - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData |
|
* - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter |
|
* - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors |
|
* - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors |
|
* - [`prepend()`](http://api.jquery.com/prepend/) |
|
* - [`prop()`](http://api.jquery.com/prop/) |
|
* - [`ready()`](http://api.jquery.com/ready/) |
|
* - [`remove()`](http://api.jquery.com/remove/) |
|
* - [`removeAttr()`](http://api.jquery.com/removeAttr/) |
|
* - [`removeClass()`](http://api.jquery.com/removeClass/) |
|
* - [`removeData()`](http://api.jquery.com/removeData/) |
|
* - [`replaceWith()`](http://api.jquery.com/replaceWith/) |
|
* - [`text()`](http://api.jquery.com/text/) |
|
* - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument |
|
* - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers |
|
* - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter |
|
* - [`val()`](http://api.jquery.com/val/) |
|
* - [`wrap()`](http://api.jquery.com/wrap/) |
|
* |
|
* ## jQuery/jqLite Extras |
|
* Angular also provides the following additional methods and events to both jQuery and jqLite: |
|
* |
|
* ### Events |
|
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event |
|
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM |
|
* element before it is removed. |
|
* |
|
* ### Methods |
|
* - `controller(name)` - retrieves the controller of the current element or its parent. By default |
|
* retrieves controller associated with the `ngController` directive. If `name` is provided as |
|
* camelCase directive name, then the controller for this directive will be retrieved (e.g. |
|
* `'ngModel'`). |
|
* - `injector()` - retrieves the injector of the current element or its parent. |
|
* - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current |
|
* element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to |
|
* be enabled. |
|
* - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the |
|
* current element. This getter should be used only on elements that contain a directive which starts a new isolate |
|
* scope. Calling `scope()` on this element always returns the original non-isolate scope. |
|
* Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. |
|
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top |
|
* parent element is reached. |
|
* |
|
* @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See |
|
* https://github.com/angular/angular.js/issues/14251 for more information. |
|
* |
|
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. |
|
* @returns {Object} jQuery object. |

|
* Creates an injector object that can be used for retrieving services as well as for |
|
* dependency injection (see {@link guide/di dependency injection}). |
|
* |
|
* @param {Array.<string|Function>} modules A list of module functions or their aliases. See |

* {@link angular.module}. The `ng` module must be explicitly added. |
|
* @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which |
|
* disallows argument name annotation inference. |
|
* @returns {injector} Injector object. See {@link auto.$injector $injector}. |
|
* |
|
* @example |
|
* Typical usage |
|
* ```js |
|
* // create an injector |
|
* var $injector = angular.injector(['ng']); |
|
* |
|
* // use the injector to kick off your application |
|
* // use the type inference to auto inject arguments, or use implicit injection |
|
* $injector.invoke(function($rootScope, $compile, $document) { |
|
* $compile($document)($rootScope); |
|
* $rootScope.$digest(); |
|
* }); |
|
* ``` |
|
* |
|
* Sometimes you want to get access to the injector of a currently running Angular app |
|
* from outside Angular. Perhaps, you want to inject and compile some markup after the |
|
* application has been bootstrapped. You can do this using the extra `injector()` added |
|
* to JQuery/jqLite elements. See {@link angular.element}. |
|
* |
|
* *This is fairly rare but could be the case if a third party library is injecting the |
|
* markup.* |
|
* |
|
* In the following example a new block of HTML containing a `ng-controller` |
|
* directive is added to the end of the document body by JQuery. We then compile and link |
|
* it into the current AngularJS scope. |
|
* |
|
* ```js |
|
* var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>'); |
|
* $(document.body).append($div); |
|
* |
|
* angular.element(document).injector().invoke(function($compile) { |

|

|
* `$injector` is used to retrieve object instances as defined by |
|
* {@link auto.$provide provider}, instantiate types, invoke methods, |
|
* and load modules. |
|
* |
|
* The following always holds true: |
|

* # Injection Function Annotation |
|
* |
|
* JavaScript does not have annotations, and annotations are needed for dependency injection. The |
|
* following are all valid ways of annotating function with injection arguments and are equivalent. |
|
* |
|
* ```js |
|
* // inferred (only works if code not minified/obfuscated) |
|
* $injector.invoke(function(serviceA){}); |
|
* |
|
* // annotated |
|
* function explicit(serviceA) {}; |
|
* explicit.$inject = ['serviceA']; |
|
* $injector.invoke(explicit); |
|
* |
|
* // inline |
|
* $injector.invoke(['serviceA', function(serviceA){}]); |
|
* ``` |
|
* |
|
* ## Inference |
|
* |
|
* In JavaScript calling `toString()` on a function returns the function definition. The definition |
|
* can then be parsed and the function arguments can be extracted. This method of discovering |
|
* annotations is disallowed when the injector is in strict mode. |
|
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the |
|
* argument names. |
|
* |
|
* ## `$inject` Annotation |
|
* By adding an `$inject` property onto a function the injection parameters can be specified. |
|
* |
|
* ## Inline |
|
* As an array of injection names, where the last item in the array is the function to call. |

/** |

|
* |
|
* @description |
|
* Returns an array of service names which the function is requesting for injection. This API is |
|
* used by the injector to determine which services need to be injected into the function when the |
|
* function is invoked. There are three ways in which the function can be annotated with the needed |
|
* dependencies. |
|
* |
|
* # Argument names |
|
* |
|
* The simplest form is to extract the dependencies from the arguments of the function. This is done |
|
* by converting the function into a string using `toString()` method and extracting the argument |
|
* names. |
|
* ```js |
|
* // Given |
|
* function MyController($scope, $route) { |
|
* // ... |
|
* } |
|
* |
|
* // Then |
|
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
|
* ``` |
|
* |
|
* You can disallow this method by using strict injection mode. |
|
* |
|
* This method does not work with code minification / obfuscation. For this reason the following |
|
* annotation strategies are supported. |
|
* |
|
* # The `$inject` property |
|
* |
|
* If a function has an `$inject` property and its value is an array of strings, then the strings |
|
* represent names of services to be injected into the function. |
|
* ```js |
|
* // Given |
|
* var MyController = function(obfuscatedScope, obfuscatedRoute) { |
|
* // ... |
|
* } |
|
* // Define function dependencies |
|
* MyController['$inject'] = ['$scope', '$route']; |
|
* |
|
* // Then |
|
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
|
* ``` |
|
* |
|
* # The array notation |
|
* |
|
* It is often desirable to inline Injected functions and that's when setting the `$inject` property |
|
* is very inconvenient. In these situations using the array notation to specify the dependencies in |
|
* a way that survives minification is a better choice: |
|
* |
|
* ```js |
|
* // We wish to write this (not minification / obfuscation safe) |
|
* injector.invoke(function($compile, $rootScope) { |
|
* // ... |
|
* }); |
|
* |
|
* // We are forced to write break inlining |
|
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) { |
|
* // ... |
|
* }; |
|
* tmpFn.$inject = ['$compile', '$rootScope']; |
|
* injector.invoke(tmpFn); |
|
* |
|
* // To better support inline function the inline annotation is supported |
|
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) { |
|
* // ... |
|
* }]); |
|
* |
|
* // Therefore |
|
* expect(injector.annotate( |
|
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}]) |
|
* ).toEqual(['$compile', '$rootScope']); |
|
* ``` |
|
* |
|
* @param {Function|Array.<string|Function>} fn Function for which dependent service names need to |
|
* be retrieved as described above. |
|
* |
|
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference. |
|
* |
|
* @returns {Array.<string>} The names of the services which the function requires. |

|

|
* The {@link auto.$provide $provide} service has a number of methods for registering components |
|
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on |
|
* {@link angular.Module}. |
|
* |
|
* An Angular **service** is a singleton object created by a **service factory**. These **service |
|
* factories** are functions which, in turn, are created by a **service provider**. |
|
* The **service providers** are constructor functions. When instantiated they must contain a |
|
* property called `$get`, which holds the **service factory** function. |
|
* |
|
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the |
|
* correct **service provider**, instantiating it and then calling its `$get` **service factory** |
|
* function to get the instance of the **service**. |
|
* |
|
* Often services have no configuration options and there is no need to add methods to the service |
|
* provider. The provider will be no more than a constructor function with a `$get` property. For |
|
* these cases the {@link auto.$provide $provide} service has additional helper methods to register |
|
* services without specifying a provider. |
|
* |
|
* * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the |
|
* {@link auto.$injector $injector} |
|
* * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by |
|
* providers and services. |
|
* * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by |
|
* services, not providers. |
|
* * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function** |
|
* that will be wrapped in a **service provider** object, whose `$get` property will contain the |
|
* given factory function. |
|
* * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function** |
|
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate |
|
* a new object using the given constructor function. |
|
* * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that |
|
* will be able to modify or replace the implementation of another service. |
|
* |
|
* See the individual methods for more information and examples. |

|
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions |
|
* are constructor functions, whose instances are responsible for "providing" a factory for a |
|
* service. |
|
* |
|
* Service provider names start with the name of the service they provide followed by `Provider`. |
|
* For example, the {@link ng.$log $log} service has a provider called |
|
* {@link ng.$logProvider $logProvider}. |
|
* |
|
* Service provider objects can have additional methods which allow configuration of the provider |
|
* and its service. Importantly, you can configure what kind of service is created by the `$get` |
|
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a |
|
* method {@link ng.$logProvider#debugEnabled debugEnabled} |
|
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the |
|
* console or not. |
|
* |
|
* @param {string} name The name of the instance. NOTE: the provider will be available under `name + |
|
'Provider'` key. |
|
* @param {(Object|function())} provider If the provider is: |
|
* |
|
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using |
|
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created. |
|
* - `Constructor`: a new instance of the provider will be created using |
|
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`. |
|
* |
|
* @returns {Object} registered provider instance |

|
* Register a **service factory**, which will be called to return the service instance. |
|
* This is short for registering a service where its provider consists of only a `$get` property, |
|
* which is the given service factory function. |
|
* You should use {@link auto.$provide#factory $provide.factory(getFn)} if you do not need to |
|
* configure your service in a provider. |
|
* |
|
* @param {string} name The name of the instance. |
|
* @param {Function|Array.<string|Function>} $getFn The injectable $getFn for the instance creation. |
|
* Internally this is a short hand for `$provide.provider(name, {$get: $getFn})`. |
|
* @returns {Object} registered provider instance |
|
* |
|
* @example |
|
* Here is an example of registering a service |
|
* ```js |
|
* $provide.factory('ping', ['$http', function($http) { |
|
* return function ping() { |
|
* return $http.send('/ping'); |
|
* }; |
|
* }]); |
|
* ``` |
|
* You would then inject and use this service like this: |
|
* ```js |
|
* someModule.controller('Ctrl', ['ping', function(ping) { |
|
* ping(); |
|
* }]); |
|

* Register a **decorator function** with the {@link auto.$injector $injector}. A decorator function |

|
* |
|
* You can find out more about using decorators in the {@link guide/decorators} guide. |
|
* |
|
* @param {string} name The name of the service to decorate. |
|
* @param {Function|Array.<string|Function>} decorator This function will be invoked when the service needs to be |

* provided and should return the decorated service instance. The function is called using |
|
* the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable. |
|
* Local injection arguments: |

* |
|
* * `$delegate` - The original service instance, which can be replaced, monkey patched, configured, |

* decorated or delegated to. |

* {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}. |
|
* |
|
* Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a |

* {@link ng.$location#hash $location.hash()} will be used. |

* |
|
* @property {(number|function|jqLite)} yOffset |
|
* If set, specifies a vertical scroll-offset. This is often useful when there are fixed |
|
* positioned elements at the top of the page, such as navbars, headers etc. |
|
* |
|
* `yOffset` can be specified in various ways: |
|
* - **number**: A fixed number of pixels to be used as offset.<br /><br /> |
|
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return |
|
* a number representing the offset (in pixels).<br /><br /> |
|
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from |
|
* the top of the page to the element's bottom will be used as offset.<br /> |
|
* **Note**: The element will be taken into account only as long as its `position` is set to |
|
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust |
|
* their height and/or positioning according to the viewport's size. |
|
* |
|
* <br /> |
|
* <div class="alert alert-warning"> |
|
* In order for `yOffset` to work properly, scrolling should take place on the document's root and |
|
* not some child element. |

|
* `ngShow`, `ngHide` and `ngMessages` also provide support for animations. |
|

* </div> |
|
* |
|
* ## Comprehensive Directive API |
|
* |
|
* There are many different options for a directive. |
|
* |
|
* The difference resides in the return value of the factory function. |
|
* You can either return a "Directive Definition Object" (see below) that defines the directive properties, |
|
* or just the `postLink` function (all other properties will have the default values). |
|
* |
|
* <div class="alert alert-success"> |
|
* **Best Practice:** It's recommended to use the "directive definition object" form. |
|
* </div> |
|
* |
|
* Here's an example directive declared with a Directive Definition Object: |
|
* |
|
* ```js |
|
* var myModule = angular.module(...); |
|
* |
|
* myModule.directive('directiveName', function factory(injectables) { |
|
* var directiveDefinitionObject = { |
|
* priority: 0, |
|
* template: '<div></div>', // or // function(tElement, tAttrs) { ... }, |
|
* // or |
|
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... }, |
|
* transclude: false, |
|
* restrict: 'A', |
|
* templateNamespace: 'html', |
|
* scope: false, |
|
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, |
|
* controllerAs: 'stringIdentifier', |
|
* bindToController: false, |
|
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], |
|
* compile: function compile(tElement, tAttrs, transclude) { |
|
* return { |
|
* pre: function preLink(scope, iElement, iAttrs, controller) { ... }, |
|
* post: function postLink(scope, iElement, iAttrs, controller) { ... } |
|
* } |
|
* // or |
|
* // return function postLink( ... ) { ... } |
|
* }, |
|
* // or |
|
* // link: { |
|
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... }, |
|
* // post: function postLink(scope, iElement, iAttrs, controller) { ... } |
|
* // } |
|
* // or |
|
* // link: function postLink( ... ) { ... } |
|
* }; |
|
* return directiveDefinitionObject; |
|
* }); |
|
* ``` |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** Any unspecified options will use the default value. You can see the default values below. |
|
* </div> |
|
* |
|
* Therefore the above can be simplified as: |
|
* |
|
* ```js |
|
* var myModule = angular.module(...); |
|
* |
|
* myModule.directive('directiveName', function factory(injectables) { |
|
* var directiveDefinitionObject = { |
|
* link: function postLink(scope, iElement, iAttrs) { ... } |
|
* }; |
|
* return directiveDefinitionObject; |
|

|
* ### Directive Definition Object |
|
* |
|
* The directive definition object provides instructions to the {@link ng.$compile |
|
* compiler}. The attributes are: |
|
* |
|
* #### `multiElement` |
|
* When this property is set to true, the HTML compiler will collect DOM nodes between |
|
* nodes with the attributes `directive-name-start` and `directive-name-end`, and group them |
|
* together as the directive elements. It is recommended that this feature be used on directives |
|
* which are not strictly behavioral (such as {@link ngClick}), and which |
|
* do not manipulate or replace child nodes (such as {@link ngInclude}). |
|
* |
|
* #### `priority` |
|
* When there are multiple directives defined on a single DOM element, sometimes it |
|
* is necessary to specify the order in which the directives are applied. The `priority` is used |
|
* to sort the directives before their `compile` functions get called. Priority is defined as a |
|
* number. Directives with greater numerical `priority` are compiled first. Pre-link functions |
|
* are also run in priority order, but post-link functions are run in reverse order. The order |
|
* of directives with the same priority is undefined. The default priority is `0`. |
|
* |
|
* #### `terminal` |
|
* If set to true then the current `priority` will be the last set of directives |
|
* which will execute (any directives at the current priority will still execute |
|
* as the order of execution on same `priority` is undefined). Note that expressions |
|
* and other directives used in the directive's template will also be excluded from execution. |
|
* |
|
* #### `scope` |
|
* The scope property can be `true`, an object or a falsy value: |
|
* |
|
* * **falsy:** No scope will be created for the directive. The directive will use its parent's scope. |
|
* |
|
* * **`true`:** A new child scope that prototypically inherits from its parent will be created for |
|
* the directive's element. If multiple directives on the same element request a new scope, |
|
* only one new scope is created. The new scope rule does not apply for the root of the template |
|
* since the root of the template always gets a new scope. |
|
* |
|
* * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The |
|
* 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent |
|
* scope. This is useful when creating reusable components, which should not accidentally read or modify |
|
* data in the parent scope. |
|
* |
|
* The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the |
|
* directive's element. These local properties are useful for aliasing values for templates. The keys in |
|
* the object hash map to the name of the property on the isolate scope; the values define how the property |
|
* is bound to the parent scope, via matching attributes on the directive's element: |
|
* |
|
* * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is |
|
* always a string since DOM attributes are strings. If no `attr` name is specified then the |
|
* attribute name is assumed to be the same as the local name. Given `<my-component |
|
* my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`, |
|
* the directive's scope property `localName` will reflect the interpolated value of `hello |
|
* {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's |
|
* scope. The `name` is read from the parent scope (not the directive's scope). |
|
* |
|
* * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression |
|
* passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. |
|
* If no `attr` name is specified then the attribute name is assumed to be the same as the local |
|
* name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: { |
|
* localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the |
|
* value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in |
|
* `localModel` and vice versa. Optional attributes should be marked as such with a question mark: |
|
* `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't |
|
* optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`}) |
|
* will be thrown upon discovering changes to the local value, since it will be impossible to sync |
|
* them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`} |
|
* method is used for tracking changes, and the equality check is based on object identity. |
|
* However, if an object literal or an array literal is passed as the binding expression, the |
|
* equality check is done by value (using the {@link angular.equals} function). It's also possible |
|
* to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection |
|
* `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional). |
|
* |
|
* * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an |
|
* expression passed via the attribute `attr`. The expression is evaluated in the context of the |
|
* parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the |
|
* local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`. |
|
* |
|
* For example, given `<my-component my-attr="parentModel">` and directive definition of |
|
* `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the |
|
* value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected |
|
* in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however |
|
* two caveats: |
|
* 1. one-way binding does not copy the value from the parent to the isolate scope, it simply |
|
* sets the same value. That means if your bound value is an object, changes to its properties |
|
* in the isolated scope will be reflected in the parent scope (because both reference the same object). |
|
* 2. one-way binding watches changes to the **identity** of the parent value. That means the |
|
* {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference |
|
* to the value has changed. In most cases, this should not be of concern, but can be important |
|
* to know if you one-way bind to an object, and then replace that object in the isolated scope. |
|
* If you now change a property of the object in your parent scope, the change will not be |
|
* propagated to the isolated scope, because the identity of the object on the parent scope |
|
* has not changed. Instead you must assign a new object. |
|
* |
|
* One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings |
|
* back to the parent. However, it does not make this completely impossible. |
|
* |
|
* * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If |
|
* no `attr` name is specified then the attribute name is assumed to be the same as the local name. |
|
* Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: { |
|
* localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for |
|
* the `count = count + value` expression. Often it's desirable to pass data from the isolated scope |
|
* via an expression to the parent scope. This can be done by passing a map of local variable names |
|
* and values into the expression wrapper fn. For example, if the expression is `increment(amount)` |
|
* then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. |
|
* |
|
* In general it's possible to apply more than one directive to one element, but there might be limitations |
|
* depending on the type of scope required by the directives. The following points will help explain these limitations. |
|
* For simplicity only two directives are taken into account, but it is also applicable for several directives: |
|
* |
|
* * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope |
|
* * **child scope** + **no scope** => Both directives will share one single child scope |
|
* * **child scope** + **child scope** => Both directives will share one single child scope |
|
* * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use |
|
* its parent's scope |
|
* * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot |
|
* be applied to the same element. |
|
* * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives |
|
* cannot be applied to the same element. |
|
* |
|
* |
|
* #### `bindToController` |
|
* This property is used to bind scope properties directly to the controller. It can be either |
|
* `true` or an object hash with the same format as the `scope` property. Additionally, a controller |
|
* alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller |
|
* definition: `controller: 'myCtrl as myAlias'`. |
|
* |
|
* When an isolate scope is used for a directive (see above), `bindToController: true` will |
|
* allow a component to have its properties bound to the controller, rather than to scope. |
|
* |
|
* After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller |
|
* properties. You can access these bindings once they have been initialized by providing a controller method called |
|
* `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings |
|
* initialized. |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Deprecation warning:** although bindings for non-ES6 class controllers are currently |
|
* bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization |
|
* code that relies upon bindings inside a `$onInit` method on the controller, instead. |
|
* </div> |
|
* |
|
* It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. |
|
* This will set up the scope bindings to the controller directly. Note that `scope` can still be used |
|
* to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate |
|
* scope (useful for component directives). |
|
* |
|
* If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. |
|
* |
|
* |
|
* #### `controller` |
|
* Controller constructor function. The controller is instantiated before the |
|
* pre-linking phase and can be accessed by other directives (see |
|
* `require` attribute). This allows the directives to communicate with each other and augment |
|
* each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: |
|
* |
|
* * `$scope` - Current scope associated with the element |
|
* * `$element` - Current element |
|
* * `$attrs` - Current attributes object for the element |
|
* * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: |
|
* `function([scope], cloneLinkingFn, futureParentElement, slotName)`: |
|
* * `scope`: (optional) override the scope. |
|
* * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. |
|
* * `futureParentElement` (optional): |
|
* * defines the parent to which the `cloneLinkingFn` will add the cloned elements. |
|
* * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. |
|
* * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) |
|
* and when the `cloneLinkinFn` is passed, |
|
* as those elements need to created and cloned in a special way when they are defined outside their |
|
* usual containers (e.g. like `<svg>`). |
|
* * See also the `directive.templateNamespace` property. |
|
* * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) |
|
* then the default translusion is provided. |
|
* The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns |
|
* `true` if the specified slot contains content (i.e. one or more DOM nodes). |
|
* |
|
* The controller can provide the following methods that act as life-cycle hooks: |
|
* * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and |
|
* had their bindings initialized (and before the pre & post linking functions for the directives on |
|
* this element). This is a good place to put initialization code for your controller. |
|
* * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The |
|
* `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an |
|
* object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a |
|
* component such as cloning the bound value to prevent accidental mutation of the outer value. |
|
* * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing |
|
* external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in |
|
* the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent |
|
* components will have their `$onDestroy()` hook called before child components. |
|
* * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link |
|
* function this hook can be used to set up DOM event handlers and do direct DOM manipulation. |
|
* Note that child elements that contain `templateUrl` directives will not have been compiled and linked since |
|
* they are waiting for their template to load asynchronously and their own compilation and linking has been |
|
* suspended until that occurs. |
|
* |
|
* |
|
* #### `require` |
|
* Require another directive and inject its controller as the fourth argument to the linking function. The |
|
* `require` property can be a string, an array or an object: |
|
* * a **string** containing the name of the directive to pass to the linking function |
|
* * an **array** containing the names of directives to pass to the linking function. The argument passed to the |
|
* linking function will be an array of controllers in the same order as the names in the `require` property |
|
* * an **object** whose property values are the names of the directives to pass to the linking function. The argument |
|
* passed to the linking function will also be an object with matching keys, whose values will hold the corresponding |
|
* controllers. |
|
* |
|
* If the `require` property is an object and `bindToController` is truthy, then the required controllers are |
|
* bound to the controller using the keys of the `require` property. This binding occurs after all the controllers |
|
* have been constructed but before `$onInit` is called. |
|
* If the name of the required controller is the same as the local name (the key), the name can be |
|
* omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. |
|
* See the {@link $compileProvider#component} helper for an example of how this can be used. |
|
* If no such required directive(s) can be found, or if the directive does not have a controller, then an error is |
|
* raised (unless no link function is specified and the required controllers are not being bound to the directive |
|
* controller, in which case error checking is skipped). The name can be prefixed with: |
|
* |
|
* * (no prefix) - Locate the required controller on the current element. Throw an error if not found. |
|
* * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. |
|
* * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. |
|
* * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. |
|
* * `?^` - Attempt to locate the required controller by searching the element and its parents or pass |
|
* `null` to the `link` fn if not found. |
|
* * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass |
|
* `null` to the `link` fn if not found. |
|
* |
|
* |
|
* #### `controllerAs` |
|
* Identifier name for a reference to the controller in the directive's scope. |
|
* This allows the controller to be referenced from the directive template. This is especially |
|
* useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible |
|
* to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the |
|
* `controllerAs` reference might overwrite a property that already exists on the parent scope. |
|
* |
|
* |
|
* #### `restrict` |
|
* String of subset of `EACM` which restricts the directive to a specific directive |
|
* declaration style. If omitted, the defaults (elements and attributes) are used. |
|
* |
|
* * `E` - Element name (default): `<my-directive></my-directive>` |
|
* * `A` - Attribute (default): `<div my-directive="exp"></div>` |
|
* * `C` - Class: `<div class="my-directive: exp;"></div>` |
|
* * `M` - Comment: `<!-- directive: my-directive exp -->` |
|
* |
|
* |
|
* #### `templateNamespace` |
|
* String representing the document type used by the markup in the template. |
|
* AngularJS needs this information as those elements need to be created and cloned |
|
* in a special way when they are defined outside their usual containers like `<svg>` and `<math>`. |
|
* |
|
* * `html` - All root nodes in the template are HTML. Root nodes may also be |
|
* top-level elements such as `<svg>` or `<math>`. |
|
* * `svg` - The root nodes in the template are SVG elements (excluding `<math>`). |
|
* * `math` - The root nodes in the template are MathML elements (excluding `<svg>`). |
|
* |
|
* If no `templateNamespace` is specified, then the namespace is considered to be `html`. |
|
* |
|
* #### `template` |
|
* HTML markup that may: |
|
* * Replace the contents of the directive's element (default). |
|
* * Replace the directive's element itself (if `replace` is true - DEPRECATED). |
|
* * Wrap the contents of the directive's element (if `transclude` is true). |
|
* |
|
* Value may be: |
|
* |
|
* * A string. For example `<div red-on-hover>{{delete_str}}</div>`. |
|
* * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` |
|
* function api below) and returns a string value. |
|
* |
|
* |
|
* #### `templateUrl` |
|
* This is similar to `template` but the template is loaded from the specified URL, asynchronously. |
|
* |
|
* Because template loading is asynchronous the compiler will suspend compilation of directives on that element |
|
* for later when the template has been resolved. In the meantime it will continue to compile and link |
|
* sibling and parent elements as though this element had not contained any directives. |
|
* |
|
* The compiler does not suspend the entire compilation to wait for templates to be loaded because this |
|
* would result in the whole app "stalling" until all templates are loaded asynchronously - even in the |
|
* case when only one deeply nested directive has `templateUrl`. |
|
* |
|
* Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} |
|
* |
|
* You can specify `templateUrl` as a string representing the URL or as a function which takes two |
|
* arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns |
|
* a string value representing the url. In either case, the template URL is passed through {@link |
|
* $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. |
|
* |
|
* |
|
* #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) |
|
* specify what the template should replace. Defaults to `false`. |
|
* |
|
* * `true` - the template will replace the directive's element. |
|
* * `false` - the template will replace the contents of the directive's element. |
|
* |
|
* The replacement process migrates all of the attributes / classes from the old element to the new |
|
* one. See the {@link guide/directive#template-expanding-directive |
|
* Directives Guide} for an example. |
|
* |
|
* There are very few scenarios where element replacement is required for the application function, |
|
* the main one being reusable custom components that are used within SVG contexts |
|
* (because SVG doesn't work with custom elements in the DOM tree). |
|
* |
|
* #### `transclude` |
|
* Extract the contents of the element where the directive appears and make it available to the directive. |
|
* The contents are compiled and provided to the directive as a **transclusion function**. See the |
|
* {@link $compile#transclusion Transclusion} section below. |
|
* |
|
* |
|
* #### `compile` |
|
* |
|
* ```js |
|
* function compile(tElement, tAttrs, transclude) { ... } |
|
* ``` |
|
* |
|
* The compile function deals with transforming the template DOM. Since most directives do not do |
|
* template transformation, it is not used often. The compile function takes the following arguments: |
|
* |
|
* * `tElement` - template element - The element where the directive has been declared. It is |
|
* safe to do template transformation on the element and child elements only. |
|
* |
|
* * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared |
|
* between all directive compile functions. |
|
* |
|
* * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** The template instance and the link instance may be different objects if the template has |
|
* been cloned. For this reason it is **not** safe to do anything other than DOM transformations that |
|
* apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration |
|
* should be done in a linking function rather than in a compile function. |
|
* </div> |
|
|
|
* <div class="alert alert-warning"> |
|
* **Note:** The compile function cannot handle directives that recursively use themselves in their |
|
* own templates or compile functions. Compiling these directives results in an infinite loop and |
|
* stack overflow errors. |
|
* |
|
* This can be avoided by manually using $compile in the postLink function to imperatively compile |
|
* a directive's template instead of relying on automatic template compilation via `template` or |
|
* `templateUrl` declaration or manual compilation inside the compile function. |
|
* </div> |
|
* |
|
* <div class="alert alert-danger"> |
|
* **Note:** The `transclude` function that is passed to the compile function is deprecated, as it |
|
* e.g. does not know about the right outer scope. Please use the transclude function that is passed |
|
* to the link function instead. |
|
* </div> |
|
|
|
* A compile function can have a return value which can be either a function or an object. |
|
* |
|
* * returning a (post-link) function - is equivalent to registering the linking function via the |
|
* `link` property of the config object when the compile function is empty. |
|
* |
|
* * returning an object with function(s) registered via `pre` and `post` properties - allows you to |
|
* control when a linking function should be called during the linking phase. See info about |
|
* pre-linking and post-linking functions below. |
|
* |
|
* |
|
* #### `link` |
|
* This property is used only if the `compile` property is not defined. |
|
* |
|
* ```js |
|
* function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } |
|
* ``` |
|
* |
|
* The link function is responsible for registering DOM listeners as well as updating the DOM. It is |
|
* executed after the template has been cloned. This is where most of the directive logic will be |
|
* put. |
|
* |
|
* * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the |
|
* directive for registering {@link ng.$rootScope.Scope#$watch watches}. |
|
* |
|
* * `iElement` - instance element - The element where the directive is to be used. It is safe to |
|
* manipulate the children of the element only in `postLink` function since the children have |
|
* already been linked. |
|
* |
|
* * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared |
|
* between all directive linking functions. |
|
* |
|
* * `controller` - the directive's required controller instance(s) - Instances are shared |
|
* among all directives, which allows the directives to use the controllers as a communication |
|
* channel. The exact value depends on the directive's `require` property: |
|
* * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one |
|
* * `string`: the controller instance |
|
* * `array`: array of controller instances |
|
* |
|
* If a required controller cannot be found, and it is optional, the instance is `null`, |
|
* otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. |
|
* |
|
* Note that you can also require the directive's own controller - it will be made available like |
|
* any other controller. |
|
* |
|
* * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. |
|
* This is the same as the `$transclude` |
|
* parameter of directive controllers, see there for details. |
|
* `function([scope], cloneLinkingFn, futureParentElement)`. |
|
* |
|
* #### Pre-linking function |
|
* |
|
* Executed before the child elements are linked. Not safe to do DOM transformation since the |
|
* compiler linking function will fail to locate the correct elements for linking. |
|
* |
|
* #### Post-linking function |
|
* |
|
* Executed after the child elements are linked. |
|
* |
|
* Note that child elements that contain `templateUrl` directives will not have been compiled |
|
* and linked since they are waiting for their template to load asynchronously and their own |
|
* compilation and linking has been suspended until that occurs. |
|
* |
|
* It is safe to do DOM transformation in the post-linking function on elements that are not waiting |
|
* for their async templates to be resolved. |
|
* |
|
* |
|
* ### Transclusion |
|
* |
|
* Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and |
|
* copying them to another part of the DOM, while maintaining their connection to the original AngularJS |
|
* scope from where they were taken. |
|
* |
|
* Transclusion is used (often with {@link ngTransclude}) to insert the |
|
* original contents of a directive's element into a specified place in the template of the directive. |
|
* The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded |
|
* content has access to the properties on the scope from which it was taken, even if the directive |
|
* has isolated scope. |
|
* See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. |
|
* |
|
* This makes it possible for the widget to have private state for its template, while the transcluded |
|
* content has access to its originating scope. |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** When testing an element transclude directive you must not place the directive at the root of the |
|
* DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives |
|
* Testing Transclusion Directives}. |
|
* </div> |
|
* |
|
* There are three kinds of transclusion depending upon whether you want to transclude just the contents of the |
|
* directive's element, the entire element or multiple parts of the element contents: |
|
* |
|
* * `true` - transclude the content (i.e. the child nodes) of the directive's element. |
|
* * `'element'` - transclude the whole of the directive's element including any directives on this |
|
* element that defined at a lower priority than this directive. When used, the `template` |
|
* property is ignored. |
|
* * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. |
|
* |
|
* **Mult-slot transclusion** is declared by providing an object for the `transclude` property. |
|
* |
|
* This object is a map where the keys are the name of the slot to fill and the value is an element selector |
|
* used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) |
|
* and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). |
|
* |
|
* For further information check out the guide on {@link guide/directive#matching-directives Matching Directives} |
|
* |
|
* If the element selector is prefixed with a `?` then that slot is optional. |
|
* |
|
* For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to |
|
* the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. |
|
* |
|
* Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements |
|
* in the transclude content. If you wish to know if an optional slot was filled with content, then you can call |
|
* `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and |
|
* injectable into the directive's controller. |
|
* |
|
* |
|
* #### Transclusion Functions |
|
* |
|
* When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion |
|
* function** to the directive's `link` function and `controller`. This transclusion function is a special |
|
* **linking function** that will return the compiled contents linked to a new transclusion scope. |
|
* |
|
* <div class="alert alert-info"> |
|
* If you are just using {@link ngTransclude} then you don't need to worry about this function, since |
|
* ngTransclude will deal with it for us. |
|
* </div> |
|
* |
|
* If you want to manually control the insertion and removal of the transcluded content in your directive |
|
* then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery |
|
* object that contains the compiled DOM, which is linked to the correct transclusion scope. |
|
* |
|
* When you call a transclusion function you can pass in a **clone attach function**. This function accepts |
|
* two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded |
|
* content and the `scope` is the newly created transclusion scope, to which the clone is bound. |
|
* |
|
* <div class="alert alert-info"> |
|
* **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function |
|
* since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. |
|
* </div> |
|
* |
|
* It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone |
|
* attach function**: |
|
* |
|
* ```js |
|
* var transcludedContent, transclusionScope; |
|
* |
|
* $transclude(function(clone, scope) { |
|
* element.append(clone); |
|
* transcludedContent = clone; |
|
* transclusionScope = scope; |
|
* }); |
|
* ``` |
|
* |
|
* Later, if you want to remove the transcluded content from your DOM then you should also destroy the |
|
* associated transclusion scope: |
|
* |
|
* ```js |
|
* transcludedContent.remove(); |
|
* transclusionScope.$destroy(); |
|
* ``` |
|
* |
|
* <div class="alert alert-info"> |
|
* **Best Practice**: if you intend to add and remove transcluded content manually in your directive |
|
* (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), |
|
* then you are also responsible for calling `$destroy` on the transclusion scope. |
|
* </div> |
|
* |
|
* The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} |
|
* automatically destroy their transcluded clones as necessary so you do not need to worry about this if |
|
* you are simply using {@link ngTransclude} to inject the transclusion into your directive. |
|
* |
|
* |
|
* #### Transclusion Scopes |
|
* |
|
* When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion |
|
* scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed |
|
* when the directive's scope gets destroyed) but it inherits the properties of the scope from which it |
|
* was taken. |
|
* |
|
* For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look |
|
* like this: |
|
* |
|
* ```html |
|
* <div ng-app> |
|
* <div isolate> |
|
* <div transclusion> |
|
* </div> |
|
* </div> |
|
* </div> |
|
* ``` |
|
* |
|
* The `$parent` scope hierarchy will look like this: |
|
* |
|
``` |
|
- $rootScope |
|
- isolate |
|
- transclusion |
|
``` |
|
* |
|
* but the scopes will inherit prototypically from different scopes to their `$parent`. |
|
* |
|
``` |
|
- $rootScope |
|
- transclusion |
|
- isolate |
|
``` |
|
* |
|
* |
|
* ### Attributes |
|
* |
|
* The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the |
|
* `link()` or `compile()` functions. It has a variety of uses. |
|
* |
|
* * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways: |
|
* 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access |
|
* to the attributes. |
|
* |
|
* * *Directive inter-communication:* All directives share the same instance of the attributes |
|
* object which allows the directives to use the attributes object as inter directive |
|
* communication. |
|
* |
|
* * *Supports interpolation:* Interpolation attributes are assigned to the attribute object |
|
* allowing other directives to read the interpolated value. |
|
* |
|
* * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes |
|
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also |
|
* the only way to easily get the actual value because during the linking phase the interpolation |
|
* hasn't been evaluated yet and so the value is at this time set to `undefined`. |
|
* |
|
* ```js |
|
* function linkingFn(scope, elm, attrs, ctrl) { |
|
* // get the attribute value |
|
* console.log(attrs.ngModel); |
|
* |
|
* // change the attribute |
|
* attrs.$set('ngModel', 'new value'); |
|
* |
|
* // observe changes to interpolated attribute |
|
* attrs.$observe('ngModel', function(value) { |
|
* console.log('ngModel has changed value to ' + value); |
|
* }); |
|
* } |
|
* ``` |
|
* |
|
* ## Example |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note**: Typically directives are registered with `module.directive`. The example below is |
|
* to illustrate how `$compile` works. |
|
* </div> |
|
* |
|
<example module="compileExample"> |
|
<file name="index.html"> |
|
<script> |
|
angular.module('compileExample', [], function($compileProvider) { |
|
// configure new 'compile' directive by passing a directive |
|
// factory function. The factory function injects the '$compile' |
|
$compileProvider.directive('compile', function($compile) { |
|
// directive factory creates a link function |
|
return function(scope, element, attrs) { |
|
scope.$watch( |
|
function(scope) { |
|
// watch the 'compile' expression for changes |
|
return scope.$eval(attrs.compile); |
|
}, |
|
function(value) { |
|
// when the 'compile' expression changes |
|
// assign it into the current DOM |
|
element.html(value); |
|
|
|
// compile the new DOM and link it to the current |
|
// scope. |
|
// NOTE: we only compile .childNodes so that |
|
// we don't get into infinite loop compiling ourselves |
|
$compile(element.contents())(scope); |
|
} |
|
); |
|
}; |
|
}); |
|
}) |
|
.controller('GreeterController', ['$scope', function($scope) { |
|
$scope.name = 'Angular'; |
|
$scope.html = 'Hello {{name}}'; |
|
}]); |
|
</script> |
|
<div ng-controller="GreeterController"> |
|
<input ng-model="name"> <br/> |
|
<textarea ng-model="html"></textarea> <br/> |
|
<div compile="html"></div> |
|
</div> |

</file> |
|
<file name="protractor.js" type="protractor"> |
|
it('should auto compile', function() { |
|
var textarea = $('textarea'); |
|
var output = $('div[compile]'); |
|
// The initial state reads 'Hello Angular'. |
|
expect(output.getText()).toBe('Hello Angular'); |
|
textarea.clear(); |
|
textarea.sendKeys('{{name}}!'); |

* |
|
* @param {number} maxPriority only apply directives lower than given priority (Only effects the |

* @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template |
|
* (a DOM element/tree) to a scope. Where: |
|
* |
|
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. |
|
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the |
|
* `template` and call the `cloneAttachFn` function allowing the caller to attach the |
|
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is |
|
* called as: <br/> `cloneAttachFn(clonedElement, scope)` where: |
|
* |
|
* * `clonedElement` - is a clone of the original `element` passed into the compiler. |
|
* * `scope` - is the current scope with which the linking function is working with. |
|
* |
|
* * `options` - An optional object hash with linking options. If `options` is provided, then the following |
|
* keys may be used to control linking behavior: |
|
* |
|
* * `parentBoundTranscludeFn` - the transclude function made available to |
|
* directives; if given, it will be passed through to the link functions of |
|
* directives found in `element` during compilation. |
|
* * `transcludeControllers` - an object hash with keys that map controller names |
|
* to a hash with the key `instance`, which maps to the controller instance; |
|
* if given, it will make the controllers available to directives on the compileNode: |
|
* ``` |
|
* { |
|
* parent: { |
|
* instance: parentControllerInstance |
|
* } |
|
* } |
|
* ``` |
|
* * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add |
|
* the cloned elements; only needed for transcludes that are allowed to contain non html |
|
* elements (e.g. SVG elements). See also the directive.controller property. |
|
* |
|
* Calling the linking function returns the element of the template. It is either the original |
|
* element passed in, or the clone of the element if the `cloneAttachFn` is provided. |
|
* |
|
* After linking the view is not updated until after a call to $digest which typically is done by |
|
* Angular automatically. |
|
* |
|
* If you need access to the bound view, there are two ways to do it: |
|
* |
|
* - If you are not asking the linking function to clone the template, create the DOM element(s) |
|
* before you send them to the compiler and keep this reference around. |
|
* ```js |
|
* var element = $compile('<p>{{total}}</p>')(scope); |
|
* ``` |
|
* |
|
* - if on the other hand, you need the element to be cloned, the view reference from the original |
|
* example would not point to the clone, but rather to the original template that was cloned. In |
|
* this case, you can access the clone via the cloneAttachFn: |
|
* ```js |
|
* var templateElement = angular.element('<p>{{total}}</p>'), |
|
* scope = ....; |
|
* |
|
* var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { |
|
* //attach the clone to DOM document at the right place |
|
* }); |
|
* |
|
* //now we have reference to the cloned DOM via `clonedElement` |
|
* ``` |
|
* |
|
* |
|
* For information on how the compiler works, see the |
|
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. |

* @description |
|
* Register a **component definition** with the compiler. This is a shorthand for registering a special |
|
* type of directive, which represents a self-contained UI component in your application. Such components |
|
* are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`). |
|
* |
|
* Component definitions are very simple and do not require as much configuration as defining general |
|
* directives. Component definitions usually consist only of a template and a controller backing it. |
|
* |
|
* In order to make the definition easier, components enforce best practices like use of `controllerAs`, |
|
* `bindToController`. They always have **isolate scope** and are restricted to elements. |
|
* |
|
* Here are a few examples of how you would usually define components: |
|
* |
|
* ```js |
|
* var myMod = angular.module(...); |
|
* myMod.component('myComp', { |
|
* template: '<div>My name is {{$ctrl.name}}</div>', |
|
* controller: function() { |
|
* this.name = 'shahar'; |
|
* } |
|
* }); |
|
* |
|
* myMod.component('myComp', { |
|
* template: '<div>My name is {{$ctrl.name}}</div>', |
|
* bindings: {name: '@'} |
|
* }); |
|
* |
|
* myMod.component('myComp', { |
|
* templateUrl: 'views/my-comp.html', |
|
* controller: 'MyCtrl', |
|
* controllerAs: 'ctrl', |
|
* bindings: {name: '@'} |
|
* }); |
|
* |
|
* ``` |
|
* For more examples, and an in-depth guide, see the {@link guide/component component guide}. |
|
* |
|
* <br /> |
|
* See also {@link ng.$compileProvider#directive $compileProvider.directive()}. |

|

|
* @description |
|
* Any uncaught exception in angular expressions is delegated to this service. |
|
* The default implementation simply delegates to `$log.error` which logs it into |
|
* the browser console. |
|
* |
|
* In unit tests, if `angular-mocks.js` is loaded, this service is overridden by |
|
* {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing. |
|
* |
|
* ## Example: |
|
* |
|
* ```js |
|
* angular.module('exceptionOverride', []).factory('$exceptionHandler', function() { |
|
* return function(exception, cause) { |
|
* exception.message += ' (caused by "' + cause + '")'; |
|
* throw exception; |
|
* }; |
|
* }); |
|
* ``` |
|
* |
|
* This example will override the normal action of `$exceptionHandler`, to make angular |
|
* exceptions fail hard when they happen, instead of just logging to the console. |
|
* |
|
* <hr /> |
|
* Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind` |
|
* methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler} |
|
* (unless executed during a digest). |
|
* |
|
* If you wish, you can manually delegate exceptions, e.g. |
|
* `try { ... } catch(e) { $exceptionHandler(e); }` |
|
* |
|
* @param {Error} exception Exception associated with the error. |
|
* @param {string=} cause optional information about the context in which |
|
* the error was thrown. |

* @description |
|
* The `$http` service is a core Angular service that facilitates communication with the remote |
|
* HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest) |
|
* object or via [JSONP](http://en.wikipedia.org/wiki/JSONP). |
|
* |
|
* For unit testing applications that use `$http` service, see |
|
* {@link ngMock.$httpBackend $httpBackend mock}. |
|
* |
|
* For a higher level of abstraction, please check out the {@link ngResource.$resource |
|
* $resource} service. |
|
* |
|
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by |
|
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage |
|
* it is important to familiarize yourself with these APIs and the guarantees they provide. |
|
* |
|
* |
|
* ## General usage |
|
* The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — |
|
* that is used to generate an HTTP request and returns a {@link ng.$q promise}. |
|
* |
|
* ```js |
|
* // Simple GET request example: |
|
* $http({ |
|
* method: 'GET', |
|
* url: '/someUrl' |
|
* }).then(function successCallback(response) { |
|
* // this callback will be called asynchronously |
|
* // when the response is available |
|
* }, function errorCallback(response) { |
|
* // called asynchronously if an error occurs |
|
* // or server returns response with an error status. |
|
* }); |
|
* ``` |
|
* |
|
* The response object has these properties: |
|
* |
|
* - **data** – `{string|Object}` – The response body transformed with the transform |
|
* functions. |
|
* - **status** – `{number}` – HTTP status code of the response. |
|
* - **headers** – `{function([headerName])}` – Header getter function. |
|
* - **config** – `{Object}` – The configuration object that was used to generate the request. |
|
* - **statusText** – `{string}` – HTTP status text of the response. |
|
* |
|
* A response status code between 200 and 299 is considered a success status and will result in |
|
* the success callback being called. Any response status code outside of that range is |
|
* considered an error status and will result in the error callback being called. |
|
* Also, status codes less than -1 are normalized to zero. -1 usually means the request was |
|
* aborted, e.g. using a `config.timeout`. |
|
* Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning |
|
* that the outcome (success or error) will be determined by the final response status code. |
|
* |
|
* |
|
* ## Shortcut methods |
|
* |
|
* Shortcut methods are also available. All shortcut methods require passing in the URL, and |
|
* request data must be passed in for POST/PUT requests. An optional config can be passed as the |
|
* last argument. |
|
* |
|
* ```js |
|
* $http.get('/someUrl', config).then(successCallback, errorCallback); |
|
* $http.post('/someUrl', data, config).then(successCallback, errorCallback); |
|
* ``` |
|
* |
|
* Complete list of shortcut methods: |
|
* |
|
* - {@link ng.$http#get $http.get} |
|
* - {@link ng.$http#head $http.head} |
|
* - {@link ng.$http#post $http.post} |
|
* - {@link ng.$http#put $http.put} |
|
* - {@link ng.$http#delete $http.delete} |
|
* - {@link ng.$http#jsonp $http.jsonp} |
|
* - {@link ng.$http#patch $http.patch} |
|
* |
|
* |
|
* ## Writing Unit Tests that use $http |
|
* When unit testing (using {@link ngMock ngMock}), it is necessary to call |
|
* {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending |
|
* request using trained responses. |
|
* |
|
* ``` |
|
* $httpBackend.expectGET(...); |
|
* $http.get(...); |
|
* $httpBackend.flush(); |
|
* ``` |
|
* |
|
* ## Deprecation Notice |
|
* <div class="alert alert-danger"> |
|
* The `$http` legacy promise methods `success` and `error` have been deprecated. |
|
* Use the standard `then` method instead. |
|
* If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to |
|
* `false` then these methods will throw {@link $http:legacy `$http/legacy`} error. |
|
* </div> |
|
* |
|
* ## Setting HTTP Headers |
|
* |
|
* The $http service will automatically add certain HTTP headers to all requests. These defaults |
|
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration |
|
* object, which currently contains this default configuration: |
|
* |
|
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests): |
|
* - `Accept: application/json, text/plain, * / *` |
|
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) |
|
* - `Content-Type: application/json` |
|
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) |
|
* - `Content-Type: application/json` |
|
* |
|
* To add or overwrite these defaults, simply add or remove a property from these configuration |
|
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object |
|
* with the lowercased HTTP method name as the key, e.g. |
|
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. |
|
* |
|
* The defaults can also be set at runtime via the `$http.defaults` object in the same |
|
* fashion. For example: |
|
* |
|
* ``` |
|
* module.run(function($http) { |
|
* $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; |
|
* }); |
|
* ``` |
|
* |
|
* In addition, you can supply a `headers` property in the config object passed when |
|
* calling `$http(config)`, which overrides the defaults without changing them globally. |
|
* |
|
* To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, |
|
* Use the `headers` property, setting the desired header to `undefined`. For example: |
|
* |
|
* ```js |
|
* var req = { |
|
* method: 'POST', |
|
* url: 'http://example.com', |
|
* headers: { |
|
* 'Content-Type': undefined |
|
* }, |
|
* data: { test: 'test' } |
|
* } |
|
* |
|
* $http(req).then(function(){...}, function(){...}); |
|
* ``` |
|
* |
|
* ## Transforming Requests and Responses |
|
* |
|
* Both requests and responses can be transformed using transformation functions: `transformRequest` |
|
* and `transformResponse`. These properties can be a single function that returns |
|
* the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, |
|
* which allows you to `push` or `unshift` a new transformation function into the transformation chain. |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. |
|
* That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). |
|
* For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest |
|
* function will be reflected on the scope and in any templates where the object is data-bound. |
|
* To prevent this, transform functions should have no side-effects. |
|
* If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. |
|
* </div> |
|
* |
|
* ### Default Transformations |
|
* |
|
* The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and |
|
* `defaults.transformResponse` properties. If a request does not provide its own transformations |
|
* then these will be applied. |
|
* |
|
* You can augment or replace the default transformations by modifying these properties by adding to or |
|
* replacing the array. |
|
* |
|
* Angular provides the following default transformations: |
|
* |
|
* Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): |
|
* |
|
* - If the `data` property of the request configuration object contains an object, serialize it |
|
* into JSON format. |
|
* |
|
* Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): |
|
* |
|
* - If XSRF prefix is detected, strip it (see Security Considerations section below). |
|
* - If JSON response is detected, deserialize it using a JSON parser. |
|
* |
|
* |
|
* ### Overriding the Default Transformations Per Request |
|
* |
|
* If you wish override the request/response transformations only for a single request then provide |
|
* `transformRequest` and/or `transformResponse` properties on the configuration object passed |
|
* into `$http`. |
|
* |
|
* Note that if you provide these properties on the config object the default transformations will be |
|
* overwritten. If you wish to augment the default transformations then you must include them in your |
|
* local transformation array. |
|
* |
|
* The following code demonstrates adding a new response transformation to be run after the default response |
|
* transformations have been run. |
|
* |
|
* ```js |
|
* function appendTransform(defaults, transform) { |
|
* |
|
* // We can't guarantee that the default transformation is an array |
|
* defaults = angular.isArray(defaults) ? defaults : [defaults]; |
|
* |
|
* // Append the new transformation to the defaults |
|
* return defaults.concat(transform); |
|
* } |
|
* |
|
* $http({ |
|
* url: '...', |
|
* method: 'GET', |
|
* transformResponse: appendTransform($http.defaults.transformResponse, function(value) { |
|
* return doTransform(value); |
|
* }) |
|
* }); |
|
* ``` |
|
* |
|
* |
|
* ## Caching |
|
* |
|
* {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must |
|
* set the config.cache value or the default cache value to TRUE or to a cache object (created |
|
* with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes |
|
* precedence over the default cache value. |
|
* |
|
* In order to: |
|
* * cache all responses - set the default cache value to TRUE or to a cache object |
|
* * cache a specific response - set config.cache value to TRUE or to a cache object |
|
* |
|
* If caching is enabled, but neither the default cache nor config.cache are set to a cache object, |
|
* then the default `$cacheFactory($http)` object is used. |
|
* |
|
* The default cache value can be set by updating the |
|
* {@link ng.$http#defaults `$http.defaults.cache`} property or the |
|
* {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. |
|
* |
|
* When caching is enabled, {@link ng.$http `$http`} stores the response from the server using |
|
* the relevant cache object. The next time the same request is made, the response is returned |
|
* from the cache without sending a request to the server. |
|
* |
|
* Take note that: |
|
* |
|
* * Only GET and JSONP requests are cached. |
|
* * The cache key is the request URL including search parameters; headers are not considered. |
|
* * Cached responses are returned asynchronously, in the same way as responses from the server. |
|
* * If multiple identical requests are made using the same cache, which is not yet populated, |
|
* one request will be made to the server and remaining requests will return the same response. |
|
* * A cache-control header on the response does not affect if or how responses are cached. |
|
* |
|
* |
|
* ## Interceptors |
|
* |
|
* Before you start creating interceptors, be sure to understand the |
|
* {@link ng.$q $q and deferred/promise APIs}. |
|
* |
|
* For purposes of global error handling, authentication, or any kind of synchronous or |
|
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be |
|
* able to intercept requests before they are handed to the server and |
|
* responses before they are handed over to the application code that |
|
* initiated these requests. The interceptors leverage the {@link ng.$q |
|
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. |
|
* |
|
* The interceptors are service factories that are registered with the `$httpProvider` by |
|
* adding them to the `$httpProvider.interceptors` array. The factory is called and |
|
* injected with dependencies (if specified) and returns the interceptor. |
|
* |
|
* There are two kinds of interceptors (and two kinds of rejection interceptors): |
|
* |
|
* * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to |
|
* modify the `config` object or create a new one. The function needs to return the `config` |
|
* object directly, or a promise containing the `config` or a new `config` object. |
|
* * `requestError`: interceptor gets called when a previous interceptor threw an error or |
|
* resolved with a rejection. |
|
* * `response`: interceptors get called with http `response` object. The function is free to |
|
* modify the `response` object or create a new one. The function needs to return the `response` |
|
* object directly, or as a promise containing the `response` or a new `response` object. |
|
* * `responseError`: interceptor gets called when a previous interceptor threw an error or |
|
* resolved with a rejection. |
|
* |
|
* |
|
* ```js |
|
* // register the interceptor as a service |
|
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { |
|
* return { |
|
* // optional method |
|
* 'request': function(config) { |
|
* // do something on success |
|
* return config; |
|
* }, |
|
* |
|
* // optional method |
|
* 'requestError': function(rejection) { |
|
* // do something on error |
|
* if (canRecover(rejection)) { |
|
* return responseOrNewPromise |
|
* } |
|
* return $q.reject(rejection); |
|
* }, |
|
* |
|
* |
|
* |
|
* // optional method |
|
* 'response': function(response) { |
|
* // do something on success |
|
* return response; |
|
* }, |
|
* |
|
* // optional method |
|
* 'responseError': function(rejection) { |
|
* // do something on error |
|
* if (canRecover(rejection)) { |
|
* return responseOrNewPromise |
|
* } |
|
* return $q.reject(rejection); |
|
* } |
|
* }; |
|
* }); |
|
* |
|
* $httpProvider.interceptors.push('myHttpInterceptor'); |
|
* |
|
* |
|
* // alternatively, register the interceptor via an anonymous factory |
|
* $httpProvider.interceptors.push(function($q, dependency1, dependency2) { |
|
* return { |
|
* 'request': function(config) { |
|
* // same as above |
|
* }, |
|
* |
|
* 'response': function(response) { |
|
* // same as above |
|
* } |
|
* }; |
|
* }); |
|
* ``` |
|
* |
|
* ## Security Considerations |
|
* |
|
* When designing web applications, consider security threats from: |
|
* |
|
* - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) |
|
* - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) |
|
* |
|
* Both server and the client must cooperate in order to eliminate these threats. Angular comes |
|
* pre-configured with strategies that address these issues, but for this to work backend server |
|
* cooperation is required. |
|
* |
|
* ### JSON Vulnerability Protection |
|
* |
|
* A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) |
|
* allows third party website to turn your JSON resource URL into |
|
* [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To |
|
* counter this your server can prefix all JSON requests with following string `")]}',\n"`. |
|
* Angular will automatically strip the prefix before processing it as JSON. |
|
* |
|
* For example if your server needs to return: |
|
* ```js |
|
* ['one','two'] |
|
* ``` |
|
* |
|
* which is vulnerable to attack, your server can return: |
|
* ```js |
|
* )]}', |
|
* ['one','two'] |
|
* ``` |
|
* |
|
* Angular will strip the prefix, before processing the JSON. |
|
* |
|
* |
|
* ### Cross Site Request Forgery (XSRF) Protection |
|
* |
|
* [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by |
|
* which the attacker can trick an authenticated user into unknowingly executing actions on your |
|
* website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the |
|
* $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP |
|
* header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the |
|
* cookie, your server can be assured that the XHR came from JavaScript running on your domain. |
|
* The header will not be set for cross-domain requests. |
|
* |
|
* To take advantage of this, your server needs to set a token in a JavaScript readable session |
|
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the |
|
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure |
|
* that only JavaScript running on your domain could have sent the request. The token must be |
|
* unique for each user and must be verifiable by the server (to prevent the JavaScript from |
|
* making up its own tokens). We recommend that the token is a digest of your site's |
|
* authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) |
|
* for added security. |
|
* |
|
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName |
|
* properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, |
|
* or the per-request config object. |
|
* |
|
* In order to prevent collisions in environments where multiple Angular apps share the |
|
* same domain or subdomain, we recommend that each application uses unique cookie name. |
|
* |
|
* @param {object} config Object describing the request to be made and how it should be |
|
* processed. The object has following properties: |
|
* |
|
* - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) |
|
* - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. |
|
* - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized |
|
* with the `paramSerializer` and appended as GET parameters. |
|
* - **data** – `{string|Object}` – Data to be sent as the request message data. |
|
* - **headers** – `{Object}` – Map of strings or functions which return strings representing |
|
* HTTP headers to send to the server. If the return value of a function is null, the |
|
* header will not be sent. Functions accept a config object as an argument. |
|
* - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. |
|
* To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. |
|
* The handler will be called in the context of a `$apply` block. |
|
* - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload |
|
* object. To bind events to the XMLHttpRequest object, use `eventHandlers`. |
|
* The handler will be called in the context of a `$apply` block. |
|
* - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. |
|
* - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. |
|
* - **transformRequest** – |
|
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – |
|
* transform function or an array of such functions. The transform function takes the http |
|
* request body and headers and returns its transformed (typically serialized) version. |
|
* See {@link ng.$http#overriding-the-default-transformations-per-request |
|
* Overriding the Default Transformations} |
|
* - **transformResponse** – |
|
* `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` – |
|
* transform function or an array of such functions. The transform function takes the http |
|
* response body, headers and status and returns its transformed (typically deserialized) version. |
|
* See {@link ng.$http#overriding-the-default-transformations-per-request |
|
* Overriding the Default Transformations} |
|
* - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to |
|
* prepare the string representation of request parameters (specified as an object). |
|
* If specified as string, it is interpreted as function registered with the |
|
* {@link $injector $injector}, which means you can create your own serializer |
|

* {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response. |
|
* See {@link $http#caching $http Caching} for more information. |
|
* - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} |
|
* that should abort the request when resolved. |
|
* - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the |
|
* XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) |
|

|

|
* @requires $sce |
|
* |
|
* @description |
|
* |
|
* Compiles a string with markup into an interpolation function. This service is used by the |
|
* HTML {@link ng.$compile $compile} service for data binding. See |
|
* {@link ng.$interpolateProvider $interpolateProvider} for configuring the |
|
* interpolation markup. |
|
* |
|
* |
|
* ```js |
|
* var $interpolate = ...; // injected |
|
* var exp = $interpolate('Hello {{name | uppercase}}!'); |
|
* expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!'); |
|
* ``` |
|
* |
|
* `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is |
|
* `true`, the interpolation function will return `undefined` unless all embedded expressions |
|
* evaluate to a value other than `undefined`. |
|
* |
|
* ```js |
|
* var $interpolate = ...; // injected |
|
* var context = {greeting: 'Hello', name: undefined }; |
|
* |
|
* // default "forgiving" mode |
|
* var exp = $interpolate('{{greeting}} {{name}}!'); |
|
* expect(exp(context)).toEqual('Hello !'); |
|
* |
|
* // "allOrNothing" mode |
|
* exp = $interpolate('{{greeting}} {{name}}!', false, null, true); |
|
* expect(exp(context)).toBeUndefined(); |
|
* context.name = 'Angular'; |
|
* expect(exp(context)).toEqual('Hello Angular!'); |
|
* ``` |
|
* |
|
* `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior. |
|
* |
|
* ####Escaped Interpolation |
|
* $interpolate provides a mechanism for escaping interpolation markers. Start and end markers |
|
* can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash). |
|
* It will be rendered as a regular start/end marker, and will not be interpreted as an expression |
|
* or binding. |
|
* |
|
* This enables web-servers to prevent script injection attacks and defacing attacks, to some |
|
* degree, while also enabling code examples to work without relying on the |
|
* {@link ng.directive:ngNonBindable ngNonBindable} directive. |
|
* |
|
* **For security purposes, it is strongly encouraged that web servers escape user-supplied data, |
|
* replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all |
|
* interpolation start/end markers with their escaped counterparts.** |
|
* |
|
* Escaped interpolation markers are only replaced with the actual interpolation markers in rendered |
|
* output when the $interpolate service processes the text. So, for HTML elements interpolated |
|
* by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter |
|
* set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, |
|
* this is typically useful only when user-data is used in rendering a template from the server, or |
|
* when otherwise untrusted data is used by a directive. |
|
* |
|
* <example> |
|
* <file name="index.html"> |
|
* <div ng-init="username='A user'"> |
|
* <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\} |
|
* </p> |
|
* <p><strong>{{username}}</strong> attempts to inject code which will deface the |
|
* application, but fails to accomplish their task, because the server has correctly |
|
* escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash) |
|
* characters.</p> |
|
* <p>Instead, the result of the attempted script injection is visible, and can be removed |
|
* from the database by an administrator.</p> |
|
* </div> |
|
* </file> |
|
* </example> |
|
* |
|
* @knownIssue |
|
* It is currently not possible for an interpolated expression to contain the interpolation end |
|
* symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e. |
|
* an interpolated expression consisting of a single-quote (`'`) and the `' }}` string. |
|
* |
|
* @knownIssue |
|
* All directives and components must use the standard `{{` `}}` interpolation symbols |
|
* in their templates. If you change the application interpolation symbols the {@link $compile} |
|
* service will attempt to denormalize the standard symbols to the custom symbols. |
|
* The denormalization process is not clever enough to know not to replace instances of the standard |
|
* symbols where they would not normally be treated as interpolation symbols. For example in the following |
|
* code snippet the closing braces of the literal object will get incorrectly denormalized: |
|
* |
|
* ``` |
|
* <div data-context='{"context":{"id":3,"type":"page"}}"> |
|
* ``` |
|
* |
|
* The workaround is to ensure that such instances are separated by whitespace: |
|
* ``` |
|
* <div data-context='{"context":{"id":3,"type":"page"} }"> |
|
* ``` |
|
* |

// Sandboxing Angular Expressions |
|
// ------------------------------ |
|
// Angular expressions are generally considered safe because these expressions only have direct |
|
// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by |
|
// obtaining a reference to native JS functions such as the Function constructor. |
|
// |
|
// As an example, consider the following Angular expression: |
|
// |
|
// {}.toString.constructor('alert("evil JS code")') |
|
// |
|
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits |
|
// against the expression language, but not to prevent exploits that were enabled by exposing |
|
// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good |
|
// practice and therefore we are not even trying to protect against interaction with an object |
|
// explicitly exposed in this way. |
|
// |
|
// In general, it is not possible to access a Window object from an angular expression unless a |
|
// window or some DOM object that has a reference to window is published onto a Scope. |
|
// Similarly we prevent invocations of function known to be dangerous, as well as assignments to |
|
// native objects. |
|
// |
|
// See https://docs.angularjs.org/guide/security |

/** |
|
* @ngdoc service |
|
* @name $q |
|
* @requires $rootScope |
|
* |
|
* @description |
|
* A service that helps you run functions asynchronously, and use their return values (or exceptions) |
|
* when they are done processing. |
|
* |
|
* This is an implementation of promises/deferred objects inspired by |
|
* [Kris Kowal's Q](https://github.com/kriskowal/q). |
|
* |
|
* $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred |
|
* implementations, and the other which resembles ES6 (ES2015) promises to some degree. |
|
* |
|
* # $q constructor |
|
* |
|
* The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver` |
|
* function as the first argument. This is similar to the native Promise implementation from ES6, |
|
* see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). |
|
* |
|
* While the constructor-style use is supported, not all of the supporting methods from ES6 promises are |
|
* available yet. |
|
* |
|
* It can be used like so: |
|
* |
|
* ```js |
|
* // for the purpose of this example let's assume that variables `$q` and `okToGreet` |
|
* // are available in the current lexical scope (they could have been injected or passed in). |
|
* |
|
* function asyncGreet(name) { |
|
* // perform some asynchronous operation, resolve or reject the promise when appropriate. |
|
* return $q(function(resolve, reject) { |
|
* setTimeout(function() { |
|
* if (okToGreet(name)) { |
|
* resolve('Hello, ' + name + '!'); |
|
* } else { |
|
* reject('Greeting ' + name + ' is not allowed.'); |
|
* } |
|
* }, 1000); |
|
* }); |
|
* } |
|
* |
|
* var promise = asyncGreet('Robin Hood'); |
|
* promise.then(function(greeting) { |
|
* alert('Success: ' + greeting); |
|
* }, function(reason) { |
|
* alert('Failed: ' + reason); |
|
* }); |
|
* ``` |
|
* |
|
* Note: progress/notify callbacks are not currently supported via the ES6-style interface. |
|
* |
|
* Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise. |
|
* |
|
* However, the more traditional CommonJS-style usage is still available, and documented below. |
|
* |
|
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an |
|
* interface for interacting with an object that represents the result of an action that is |
|
* performed asynchronously, and may or may not be finished at any given point in time. |
|
* |
|
* From the perspective of dealing with error handling, deferred and promise APIs are to |
|
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. |
|
* |
|
* ```js |
|
* // for the purpose of this example let's assume that variables `$q` and `okToGreet` |
|
* // are available in the current lexical scope (they could have been injected or passed in). |
|
* |
|
* function asyncGreet(name) { |
|
* var deferred = $q.defer(); |
|
* |
|
* setTimeout(function() { |
|
* deferred.notify('About to greet ' + name + '.'); |
|
* |
|
* if (okToGreet(name)) { |
|
* deferred.resolve('Hello, ' + name + '!'); |
|
* } else { |
|
* deferred.reject('Greeting ' + name + ' is not allowed.'); |
|
* } |
|
* }, 1000); |
|
* |
|
* return deferred.promise; |
|
* } |
|
* |
|
* var promise = asyncGreet('Robin Hood'); |
|
* promise.then(function(greeting) { |
|
* alert('Success: ' + greeting); |
|
* }, function(reason) { |
|
* alert('Failed: ' + reason); |
|
* }, function(update) { |
|
* alert('Got notification: ' + update); |
|
* }); |
|
* ``` |
|
* |
|
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff |
|
* comes in the way of guarantees that promise and deferred APIs make, see |
|
* https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. |
|
* |
|
* Additionally the promise api allows for composition that is very hard to do with the |
|
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. |
|
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the |
|
* section on serial or parallel joining of promises. |
|
* |
|
* # The Deferred API |
|
* |
|
* A new instance of deferred is constructed by calling `$q.defer()`. |
|
* |
|
* The purpose of the deferred object is to expose the associated Promise instance as well as APIs |
|
* that can be used for signaling the successful or unsuccessful completion, as well as the status |
|
* of the task. |
|
* |
|
* **Methods** |
|
* |
|
* - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection |
|
* constructed via `$q.reject`, the promise will be rejected instead. |
|
* - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to |
|
* resolving it with a rejection constructed via `$q.reject`. |
|
* - `notify(value)` - provides updates on the status of the promise's execution. This may be called |
|
* multiple times before the promise is either resolved or rejected. |
|
* |
|
* **Properties** |
|
* |
|
* - promise – `{Promise}` – promise object associated with this deferred. |
|
* |
|
* |
|
* # The Promise API |
|
* |
|
* A new promise instance is created when a deferred instance is created and can be retrieved by |
|
* calling `deferred.promise`. |
|
* |
|
* The purpose of the promise object is to allow for interested parties to get access to the result |
|
* of the deferred task when it completes. |
|
* |
|
* **Methods** |
|
* |
|
* - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or |
|
* will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously |
|
* as soon as the result is available. The callbacks are called with a single argument: the result |
|
* or rejection reason. Additionally, the notify callback may be called zero or more times to |
|
* provide a progress indication, before the promise is resolved or rejected. |
|
* |
|
* This method *returns a new promise* which is resolved or rejected via the return value of the |
|
* `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved |
|
* with the value which is resolved in that promise using |
|
* [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)). |
|
* It also notifies via the return value of the `notifyCallback` method. The promise cannot be |
|
* resolved or rejected from the notifyCallback method. |
|
* |
|
* - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)` |
|
* |
|
* - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise, |
|
* but to do so without modifying the final value. This is useful to release resources or do some |
|
* clean-up that needs to be done whether the promise was rejected or resolved. See the [full |
|
* specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for |
|
* more information. |
|
* |
|
* # Chaining promises |
|
* |
|
* Because calling the `then` method of a promise returns a new derived promise, it is easily |
|
* possible to create a chain of promises: |
|
* |
|
* ```js |
|
* promiseB = promiseA.then(function(result) { |
|
* return result + 1; |
|
* }); |
|
* |
|
* // promiseB will be resolved immediately after promiseA is resolved and its value |
|
* // will be the result of promiseA incremented by 1 |
|
* ``` |
|
* |
|
* It is possible to create chains of any length and since a promise can be resolved with another |
|
* promise (which will defer its resolution further), it is possible to pause/defer resolution of |
|
* the promises at any point in the chain. This makes it possible to implement powerful APIs like |
|
* $http's response interceptors. |
|
* |
|
* |
|
* # Differences between Kris Kowal's Q and $q |
|
* |
|
* There are two main differences: |
|
* |
|
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation |
|
* mechanism in angular, which means faster propagation of resolution or rejection into your |
|

|

* // otherwise forward the rejection to promiseB |
|

/** |
|
* DESIGN NOTES |
|
* |
|
* The design decisions behind the scope are heavily favored for speed and memory consumption. |
|
* |
|
* The typical use of scope is to watch the expressions, which most of the time return the same |
|
* value as last time so we optimize the operation. |
|
* |
|
* Closures construction is expensive in terms of speed as well as memory: |
|
* - No closures, instead use prototypical inheritance for API |
|
* - Internal state needs to be stored on scope directly, which means that private state is |
|
* exposed as $$____ properties |
|
* |
|
* Loop operations are optimized by using while(count--) { ... } |
|
* - This means that in order to keep the same order of execution as addition we have to add |
|
* items to the array at the beginning (unshift) instead of at the end (push) |
|
* |
|
* Child scopes are created and removed often |
|
* - Using an array would be slow since inserts in the middle are expensive; so we use linked lists |
|
* |
|
* There are fewer watches than observers. This is why you don't want the observer to be implemented |
|
* in the same way as watch. Watch requires return of the initialization function which is expensive |
|
* to construct. |

/** |
|
* @ngdoc method |
|
* @name $rootScope.Scope#$watch |
|
* @kind function |
|
* |
|
* @description |
|
* Registers a `listener` callback to be executed whenever the `watchExpression` changes. |
|
* |
|
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest |
|
* $digest()} and should return the value that will be watched. (`watchExpression` should not change |
|
* its value when executed multiple times with the same input because it may be executed multiple |
|
* times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be |
|
* [idempotent](http://en.wikipedia.org/wiki/Idempotence). |
|
* - The `listener` is called only when the value from the current `watchExpression` and the |
|
* previous call to `watchExpression` are not equal (with the exception of the initial run, |
|
* see below). Inequality is determined according to reference inequality, |
|
* [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators) |
|
* via the `!==` Javascript operator, unless `objectEquality == true` |
|
* (see next point) |
|
* - When `objectEquality == true`, inequality of the `watchExpression` is determined |
|
* according to the {@link angular.equals} function. To save the value of the object for |
|
* later comparison, the {@link angular.copy} function is used. This therefore means that |
|
* watching complex objects will have adverse memory and performance implications. |
|
* - The watch `listener` may change the model, which may trigger other `listener`s to fire. |
|
* This is achieved by rerunning the watchers until no changes are detected. The rerun |
|
* iteration limit is 10 to prevent an infinite loop deadlock. |
|
* |
|
* |
|
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called, |
|
* you can register a `watchExpression` function with no `listener`. (Be prepared for |
|
* multiple calls to your `watchExpression` because it will execute multiple times in a |
|
* single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.) |
|
* |
|
* After a watcher is registered with the scope, the `listener` fn is called asynchronously |
|
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the |
|
* watcher. In rare cases, this is undesirable because the listener is called when the result |
|
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you |
|
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the |
|
* listener was called due to initialization. |
|
* |
|
* |
|
* |
|
* # Example |
|
* ```js |
|
// let's assume that scope was dependency injected as the $rootScope |
|
var scope = $rootScope; |
|
scope.name = 'misko'; |
|

|
* Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and |

* its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change |
|
* the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers} |

|
* iterations exceeds 10. |
|
* |
|
* Usually, you don't call `$digest()` directly in |
|
* {@link ng.directive:ngController controllers} or in |
|
* {@link ng.$compileProvider#directive directives}. |
|
* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within |
|
* a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`. |
|
* |
|
* If you want to be notified whenever `$digest()` is called, |
|
* you can register a `watchExpression` function with |
|
* {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`. |

|
* `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict |
|
* Contextual Escaping (SCE)} services to AngularJS. |
|
* |
|
* Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of |
|
* the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is |
|
* because, while the `$sce` provides numerous shorthand methods, etc., you really only need to |
|
* override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things |
|
* work because `$sce` delegates to `$sceDelegate` for these operations. |
|
* |
|
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service. |
|
* |
|
* The default instance of `$sceDelegate` should work out of the box with little pain. While you |
|
* can override it completely to change the behavior of `$sce`, the common case would |
|
* involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting |
|
* your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as |
|
* templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist |

|
* |
|
* `$sce` is a service that provides Strict Contextual Escaping services to AngularJS. |
|
* |
|
* # Strict Contextual Escaping |
|
* |
|
* Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain |
|
* contexts to result in a value that is marked as safe to use for that context. One example of |
|
* such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer |
|
* to these contexts as privileged or SCE contexts. |
|
* |
|
* As of version 1.2, Angular ships with SCE enabled by default. |
|
* |
|
* Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow |
|
* one to execute arbitrary javascript by the use of the expression() syntax. Refer |
|
* <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them. |
|
* You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>` |
|
* to the top of your HTML document. |
|
* |
|
* SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for |
|
* security vulnerabilities such as XSS, clickjacking, etc. a lot easier. |
|
* |
|
* Here's an example of a binding in a privileged context: |
|
* |
|
* ``` |
|
* <input ng-model="userHtml" aria-label="User input"> |
|
* <div ng-bind-html="userHtml"></div> |
|
* ``` |
|
* |
|
* Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE |
|
* disabled, this application allows the user to render arbitrary HTML into the DIV. |
|
* In a more realistic example, one may be rendering user comments, blog articles, etc. via |
|
* bindings. (HTML is just one example of a context where rendering user controlled input creates |
|
* security vulnerabilities.) |
|
* |
|
* For the case of HTML, you might use a library, either on the client side, or on the server side, |
|
* to sanitize unsafe HTML before binding to the value and rendering it in the document. |
|
* |
|
* How would you ensure that every place that used these types of bindings was bound to a value that |
|
* was sanitized by your library (or returned as safe for rendering by your server?) How can you |
|
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some |
|
* properties/fields and forgot to update the binding to the sanitized value? |
|
* |
|
* To be secure by default, you want to ensure that any such bindings are disallowed unless you can |
|
* determine that something explicitly says it's safe to use a value for binding in that |
|
* context. You can then audit your code (a simple grep would do) to ensure that this is only done |
|
* for those values that you can easily tell are safe - because they were received from your server, |
|
* sanitized by your library, etc. You can organize your codebase to help with this - perhaps |
|
* allowing only the files in a specific directory to do this. Ensuring that the internal API |
|
* exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. |
|
* |
|
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} |
|
* (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to |
|
* obtain values that will be accepted by SCE / privileged contexts. |
|
* |
|
* |
|
* ## How does it work? |
|
* |
|
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted |
|
* $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link |
|
* ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the |
|
* {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. |
|
* |
|
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link |
|
* ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly |
|
* simplified): |
|
* |
|
* ``` |
|
* var ngBindHtmlDirective = ['$sce', function($sce) { |
|
* return function(scope, element, attr) { |
|
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { |
|
* element.html(value || ''); |
|
* }); |
|
* }; |
|
* }]; |
|
* ``` |
|
* |
|
* ## Impact on loading templates |
|
* |
|
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as |
|
* `templateUrl`'s specified by {@link guide/directive directives}. |
|
* |
|
* By default, Angular only loads templates from the same domain and protocol as the application |
|
* document. This is done by calling {@link ng.$sce#getTrustedResourceUrl |
|
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or |
|
* protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist |
|
* them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. |
|
* |
|
* *Please note*: |
|
* The browser's |
|
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) |
|
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) |
|
* policy apply in addition to this and may further restrict whether the template is successfully |
|
* loaded. This means that without the right CORS policy, loading templates from a different domain |
|
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some |
|
* browsers. |
|
* |
|
* ## This feels like too much overhead |
|
* |
|
* It's important to remember that SCE only applies to interpolation expressions. |
|
* |
|
* If your expressions are constant literals, they're automatically trusted and you don't need to |
|
* call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. |
|
* `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works. |
|
* |
|
* Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them |
|
* through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. |
|
* |
|
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load |
|
* templates in `ng-include` from your application's domain without having to even know about SCE. |
|
* It blocks loading templates from other domains or loading templates over http from an https |
|
* served document. You can change these by setting your own custom {@link |
|
* ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link |
|
* ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. |
|
* |
|
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an |
|
* application that's secure and can be audited to verify that with much more ease than bolting |
|
* security onto an application later. |
|
* |

|
* ## What trusted context types are supported? |
|
* |
|
* | Context | Notes | |
|
* |---------------------|----------------| |
|
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | |
|
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | |
|
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. | |
|
* | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | |
|
* | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | |
|
* |
|
* ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a> |
|
* |
|
* Each element in these arrays must be one of the following: |
|
* |
|
* - **'self'** |
|
* - The special **string**, `'self'`, can be used to match against all URLs of the **same |
|
* domain** as the application document using the **same protocol**. |
|
* - **String** (except the special value `'self'`) |
|
* - The string is matched against the full *normalized / absolute URL* of the resource |
|
* being tested (substring matches are not good enough.) |
|
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters |
|
* match themselves. |
|
* - `*`: matches zero or more occurrences of any character other than one of the following 6 |
|
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use |
|
* in a whitelist. |
|
* - `**`: matches zero or more occurrences of *any* character. As such, it's not |
|
* appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. |
|
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might |
|
* not have been the intention.) Its usage at the very end of the path is ok. (e.g. |
|
* http://foo.example.com/templates/**). |
|
* - **RegExp** (*see caveat below*) |
|
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax |
|
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to |
|
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should |
|
* have good test coverage). For instance, the use of `.` in the regex is correct only in a |
|
* small number of cases. A `.` character in the regex used when matching the scheme or a |
|
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It |
|
* is highly recommended to use the string patterns and only fall back to regular expressions |
|
* as a last resort. |
|
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is |
|
* matched against the **entire** *normalized / absolute URL* of the resource being tested |
|
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags |
|
* present on the RegExp (such as multiline, global, ignoreCase) are ignored. |
|
* - If you are generating your JavaScript from some other templating engine (not |
|
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), |
|
* remember to escape your regular expression (and be aware that you might need more than |
|
* one level of escaping depending on your templating engine and the way you interpolated |
|
* the value.) Do make use of your platform's escaping mechanism as it might be good |
|
* enough before coding your own. E.g. Ruby has |
|
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) |
|
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). |
|
* Javascript lacks a similar built in function for escaping. Take a look at Google |
|
* Closure library's [goog.string.regExpEscape(s)]( |
|
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). |
|
* |
|
* Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. |

* By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when |

|
* ## Can I disable SCE completely? |
|
* |
|
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits |
|
* for little coding overhead. It will be much harder to take an SCE disabled application and |
|
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE |
|
* for cases where you have a lot of existing code that was written before SCE was introduced and |
|
* you're migrating them a module at a time. |
|
* |
|
* That said, here's how you can completely disable SCE: |
|
* |
|
* ``` |
|
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { |
|
* // Completely disable SCE. For demonstration purposes only! |
|
* // Do not use in new projects. |
|
* $sceProvider.enabled(false); |
|
* }); |
|
* ``` |

/* Design notes on the default implementation for SCE. |
|
* |
|
* The API contract for the SCE delegate |
|
* ------------------------------------- |
|
* The SCE delegate object must provide the following 3 methods: |
|
* |
|
* - trustAs(contextEnum, value) |
|
* This method is used to tell the SCE service that the provided value is OK to use in the |
|
* contexts specified by contextEnum. It must return an object that will be accepted by |
|
* getTrusted() for a compatible contextEnum and return this value. |
|
* |
|
* - valueOf(value) |
|
* For values that were not produced by trustAs(), return them as is. For values that were |
|
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if |
|
* trustAs is wrapping the given values into some type, this operation unwraps it when given |
|
* such a value. |
|
* |
|
* - getTrusted(contextEnum, value) |
|
* This function should return the a value that is safe to use in the context specified by |
|
* contextEnum or throw and exception otherwise. |
|
* |
|
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be |
|
* opaque or wrapped in some holder object. That happens to be an implementation detail. For |
|
* instance, an implementation could maintain a registry of all trusted objects by context. In |
|
* such a case, trustAs() would return the same object that was passed in. getTrusted() would |
|
* return the same object passed in if it was found in the registry under a compatible context or |
|
* throw an exception otherwise. An implementation might only wrap values some of the time based |
|
* on some criteria. getTrusted() might return a value and not throw an exception for special |
|
* constants or objects even if not wrapped. All such implementations fulfill this contract. |
|
* |
|
* |
|
* A note on the inheritance model for SCE contexts |
|
* ------------------------------------------------ |
|
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This |
|
* is purely an implementation details. |
|
* |
|
* The contract is simply this: |
|
* |
|
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) |
|
* will also succeed. |
|
* |
|
* Inheritance happens to capture this in a natural way. In some future, we |
|
* may not use inheritance anymore. That is OK because no code outside of |
|
* sce.js and sceSpecs.js would need to be aware of this detail. |

|
* Implementation Notes for non-IE browsers |
|
* ---------------------------------------- |
|
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM, |
|
* results both in the normalizing and parsing of the URL. Normalizing means that a relative |
|
* URL will be resolved into an absolute URL in the context of the application document. |
|
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related |
|
* properties are all populated to reflect the normalized URL. This approach has wide |
|
* compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See |
|
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html |
|
* |
|
* Implementation Notes for IE |
|
* --------------------------- |
|
* IE <= 10 normalizes the URL when assigned to the anchor node similar to the other |
|
* browsers. However, the parsed components will not be set if the URL assigned did not specify |
|
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We |
|
* work around that by performing the parsing in a 2nd step by taking a previously normalized |
|
* URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the |
|
* properties such as protocol, hostname, port, etc. |

* Filters are just functions which transform input to an output. However filters need to be |
|
* Dependency Injected. To achieve this a filter definition consists of a factory function which is |
|
* annotated with dependencies and is responsible for creating a filter function. |
|
* |
|
* <div class="alert alert-warning"> |
|
* **Note:** Filter names must be valid angular {@link expression} identifiers, such as `uppercase` or `orderBy`. |
|
* Names with special characters, such as hyphens and dots, are not allowed. If you wish to namespace |
|
* your filters, then you can use capitalization (`myappSubsectionFilterx`) or underscores |
|
* (`myapp_subsection_filterx`). |
|
* </div> |
|
* |
|
* ```js |
|
* // Filter registration |
|
* function MyModule($provide, $filterProvider) { |

* // create a service to demonstrate injection (not always needed) |
|
* $provide.value('greet', function(name){ |

|
* // greet service to demonstrate DI. |

* // return the filter function which uses the greet service |
|
* // to generate salutation |

* // filters need to be forgiving so check input validity |
|
* return text && greet(text) || text; |
|
* }; |
|
* }); |
|
* } |
|
* ``` |
|
* |
|
* The filter function is registered with the `$injector` under the filter name suffix with |
|
* `Filter`. |

* @kind function |
|
* |
|
* @description |
|
* Selects a subset of items from `array` and returns it as a new array. |
|
* |
|
* @param {Array} array The source array. |
|
* @param {string|Object|function()} expression The predicate to be used for selecting items from |
|
* `array`. |
|
* |
|
* Can be one of: |
|
* |
|
* - `string`: The string is used for matching against the contents of the `array`. All strings or |
|
* objects with string properties in `array` that match this string will be returned. This also |
|
* applies to nested object properties. |
|
* The predicate can be negated by prefixing the string with `!`. |
|
* |
|
* - `Object`: A pattern object can be used to filter specific properties on objects contained |
|
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items |
|
* which have property `name` containing "M" and property `phone` containing "1". A special |
|
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any |
|
* property of the object or its nested object properties. That's equivalent to the simple |
|
* substring match with a `string` as described above. The predicate can be negated by prefixing |
|
* the string with `!`. |
|
* For example `{name: "!M"}` predicate will return an array of items which have property `name` |
|
* not containing "M". |
|
* |
|
* Note that a named property will match properties on the same level only, while the special |
|
* `$` property will match properties on the same level or deeper. E.g. an array item like |
|
* `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but |
|
* **will** be matched by `{$: 'John'}`. |
|
* |
|
* - `function(value, index, array)`: A predicate function can be used to write arbitrary filters. |
|
* The function is called for each element of the array, with the element, its index, and |
|
* the entire array itself as arguments. |
|
* |
|
* The final result is an array of those elements that the predicate returned true for. |
|
* |
|
* @param {function(actual, expected)|true|undefined} comparator Comparator which is used in |
|
* determining if the expected value (from the filter expression) and actual value (from |
|
* the object in the array) should be considered a match. |
|
* |
|
* Can be one of: |
|
* |
|
* - `function(actual, expected)`: |
|
* The function will be given the object value and the predicate value to compare and |
|
* should return true if both values should be considered equal. |
|
* |
|
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. |
|
* This is essentially strict comparison of expected and actual. |
|
* |
|
* - `false|undefined`: A short hand for a function which will look for a substring match in case |
|
* insensitive way. |
|
* |
|
* Primitive values are converted to strings. Objects are not compared against primitives, |
|
* unless they have a custom `toString` method (e.g. `Date` objects). |

|
* * `'MMMM'`: Month in year (January-December) |
|
* * `'MMM'`: Month in year (Jan-Dec) |
|
* * `'MM'`: Month in year, padded (01-12) |
|
* * `'M'`: Month in year (1-12) |
|
* * `'LLLL'`: Stand-alone month in year (January-December) |
|
* * `'dd'`: Day in month, padded (01-31) |
|
* * `'d'`: Day in month (1-31) |
|
* * `'EEEE'`: Day in Week,(Sunday-Saturday) |

|
* * `'a'`: AM/PM marker |
|
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200) |
|
* * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year |
|
* * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year |

* {@link guide/i18n localizable formats}: |
|
* |
|
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale |

|
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM) |

* |
|
* `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g. |
|
* `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence |
|
* (e.g. `"h 'o''clock'"`). |
|
* |
|
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or |

* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its |
|
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is |
|
* specified in the string input, the time is considered to be in the local timezone. |
|
* @param {string=} format Formatting rules (see Description). If not specified, |
|
* `mediumDate` is used. |
|
* @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the |
|
* continental US time zone abbreviations, but for general use, use a time zone offset, for |
|
* example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian) |

* @param {Array|string|number} input Source array, string or number to be limited. |
|
* @param {string|number} limit The length of the returned array or string. If the `limit` number |
|
* is positive, `limit` number of items from the beginning of the source array/string are copied. |
|
* If the number is negative, `limit` number of items from the end of the source array/string |
|
* are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined, |
|
* the input will be returned unchanged. |
|
* @param {(string|number)=} begin Index at which to begin limitation. As a negative index, `begin` |
|
* indicates an offset from the end of `input`. Defaults to `0`. |

* @ngdoc filter |
|
* @name orderBy |
|
* @kind function |
|
* |
|
* @description |
|
* Orders a specified `array` by the `expression` predicate. It is ordered alphabetically |
|
* for strings and numerically for numbers. Note: if you notice numbers are not being sorted |
|
* as expected, make sure they are actually being saved as numbers and not strings. |
|
* Array-like values (e.g. NodeLists, jQuery objects, TypedArrays, Strings, etc) are also supported. |
|
* |
|
* @param {Array} array The array (or array-like object) to sort. |
|
* @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be |
|
* used by the comparator to determine the order of elements. |
|
* |
|
* Can be one of: |
|
* |
|
* - `function`: Getter function. The result of this function will be sorted using the |
|
* `<`, `===`, `>` operator. |
|
* - `string`: An Angular expression. The result of this expression is used to compare elements |
|
* (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by |
|
* 3 first characters of a property called `name`). The result of a constant expression |
|
* is interpreted as a property name to be used in comparisons (for example `"special name"` |
|
* to sort object by the value of their `special name` property). An expression can be |
|
* optionally prefixed with `+` or `-` to control ascending or descending sort order |
|
* (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array |
|
* element itself is used to compare where sorting. |
|
* - `Array`: An array of function or string predicates. The first predicate in the array |
|
* is used for sorting, but when two items are equivalent, the next predicate is used. |
|
* |
|
* If the predicate is missing or empty then it defaults to `'+'`. |
|
* |
|
* @param {boolean=} reverse Reverse the order of the array. |
|
* @returns {Array} Sorted copy of the source array. |
|
* |
|
* |
|
* @example |
|
* The example below demonstrates a simple ngRepeat, where the data is sorted |
|
* by age in descending order (predicate is set to `'-age'`). |
|
* `reverse` is not set, which means it defaults to `false`. |

|
* Using Angular markup like `{{hash}}` in an href attribute will |

|
* # Alias: {@link ng.directive:ngForm `ngForm`} |
|
* |
|
* In Angular, forms can be nested. This means that the outer form is valid when all of the child |
|
* forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so |
|
* Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to |
|
* `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group |
|
* of controls needs to be determined. |
|
* |
|
* # CSS classes |
|
* - `ng-valid` is set if the form is valid. |
|
* - `ng-invalid` is set if the form is invalid. |
|
* - `ng-pending` is set if the form is pending. |
|
* - `ng-pristine` is set if the form is pristine. |
|
* - `ng-dirty` is set if the form is dirty. |
|
* - `ng-submitted` is set if the form was submitted. |
|
* |
|
* Keep in mind that ngAnimate can detect each of these classes when added and removed. |
|
* |
|
* |
|
* # Submitting a form and preventing the default action |
|
* |
|
* Since the role of forms in client-side Angular applications is different than in classical |
|
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full |
|
* page reload that sends the data to the server. Instead some javascript logic should be triggered |
|
* to handle the form submission in an application-specific way. |
|
* |
|
* For this reason, Angular prevents the default action (form submission to the server) unless the |
|
* `<form>` element has an `action` attribute specified. |
|
* |
|
* You can use one of the following two ways to specify what javascript method should be called when |
|
* a form is submitted: |
|
* |
|
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element |
|
* - {@link ng.directive:ngClick ngClick} directive on the first |
|
* button or input field of type submit (input[type=submit]) |
|
* |
|
* To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} |
|
* or {@link ng.directive:ngClick ngClick} directives. |
|
* This is because of the following form submission rules in the HTML specification: |
|
* |
|
* - If a form has only one input field then hitting enter in this field triggers form submit |
|
* (`ngSubmit`) |
|
* - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter |
|
* doesn't trigger submit |
|
* - if a form has one or more input fields and one or more buttons or input[type=submit] then |
|
* hitting enter in any of the input fields will trigger the click handler on the *first* button or |
|
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) |
|
* |
|
* Any pending `ngModelOptions` changes will take place immediately when an enclosing form is |
|
* submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` |
|
* to have access to the updated model. |
|
* |
|
* ## Animation Hooks |
|
* |
|
* Animations in ngForm are triggered when any of the associated CSS classes are added and removed. |
|
* These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any |
|
* other validations that are performed within the form. Animations in ngForm are similar to how |
|
* they work in ngClass and animations can be hooked |
