| * @param {Object} [defaults={}] | |
| * the default settings of the gesture. these are added to the instance settings, | |
| * and can be overruled per instance. you can also add the name of the gesture, | |
| * but this is also added by default (and set to true). | |

| * following arguments: | |
| * | |
| * @param {Object} eventData | |
| * event data containing the following properties: | |
| * timeStamp {Number} time the event occurred | |
| * target {HTMLElement} target element | |
| * touches {Array} touches (fingers, pointers, mouse) on the screen | |
| * pointerType {String} kind of pointer that was used. matches ionic.Gestures.POINTER_MOUSE|TOUCH | |
| * center {Object} center position of the touches. contains pageX and pageY | |
| * deltaTime {Number} the total time of the touches in the screen | |
| * deltaX {Number} the delta on x axis we haved moved | |
| * deltaY {Number} the delta on y axis we haved moved | |
| * velocityX {Number} the velocity on the x | |
| * velocityY {Number} the velocity on y | |
| * angle {Number} the angle we are moving | |
| * direction {String} the direction we are moving. matches ionic.Gestures.DIRECTION_UP|DOWN|LEFT|RIGHT | |
| * distance {Number} the distance we haved moved | |
| * scale {Number} scaling of the touches, needs 2 touches | |
| * rotation {Number} rotation of the touches, needs 2 touches * | |
| * eventType {String} matches ionic.Gestures.EVENT_START|MOVE|END | |
| * srcEvent {Object} the source event, like TouchStart or MouseDown * | |
| * startEvent {Object} contains the same properties as above, | |
| * but from the first touch. this is used to calculate | |
| * distances, deltaTime, scaling etc | |
| * | |
| * @param {ionic.Gestures.Instance} inst | |
| * the instance we are doing the detection for. you can get the options from | |
| * the inst.options object and trigger the gesture event by calling inst.trigger | |
| * | |
| * | |
| * Handle gestures | |
| * -------------------- | |
| * inside the handler you can get/set ionic.Gestures.detectionic.current. This is the current | |
| * detection sessionic. It has the following properties | |
| * @param {String} name | |
| * contains the name of the gesture we have detected. it has not a real function, | |
| * only to check in other gestures if something is detected. | |
| * like in the drag gesture we set it to 'drag' and in the swipe gesture we can | |
| * check if the current gesture is 'drag' by accessing ionic.Gestures.detectionic.current.name | |
| * | |
| * readonly | |
| * @param {ionic.Gestures.Instance} inst | |
| * the instance we do the detection for | |
| * | |
| * readonly | |
| * @param {Object} startEvent | |
| * contains the properties of the first gesture detection in this sessionic. | |
| * Used for calculations about timing, distance, etc. | |
| * | |
| * readonly | |
| * @param {Object} lastEvent | |
| * contains all the properties of the last gesture detect in this sessionic. | |
| * | |
| * after the gesture detection session has been completed (user has released the screen) | |
| * the ionic.Gestures.detectionic.current object is copied into ionic.Gestures.detectionic.previous, | |
| * this is usefull for gestures like doubletap, where you need to know if the | |
| * previous gesture was a tap | |
| * | |
| * options that have been set by the instance can be received by calling inst.options | |
| * | |
| * You can trigger a gesture event by calling inst.trigger("mygesture", event). | |
| * The first param is the name of your gesture, the second the event argument | |
| * | |
| * | |
| * Register gestures | |
| * -------------------- | |
| * When an gesture is added to the ionic.Gestures.gestures object, it is auto registered | |
| * at the setup of the first ionic.Gestures instance. You can also call ionic.Gestures.detectionic.register | |
| * manually and pass your gesture object as a param | |

| * @ngdoc page | |
| * @name tap | |
| * @module ionic | |
| * @description | |
| * On touch devices such as a phone or tablet, some browsers implement a 300ms delay between | |
| * the time the user stops touching the display and the moment the browser executes the | |
| * click. This delay was initially introduced so the browser can know whether the user wants to | |
| * double-tap to zoom in on the webpage. Basically, the browser waits roughly 300ms to see if | |
| * the user is double-tapping, or just tapping on the display once. | |
| * | |
| * Out of the box, Ionic automatically removes the 300ms delay in order to make Ionic apps | |
| * feel more "native" like. Resultingly, other solutions such as | |
| * [fastclick](https://github.com/ftlabs/fastclick) and Angular's | |
| * [ngTouch](https://docs.angularjs.org/api/ngTouch) should not be included, to avoid conflicts. | |
| * | |
| * Some browsers already remove the delay with certain settings, such as the CSS property | |
| * `touch-events: none` or with specific meta tag viewport values. However, each of these | |
| * browsers still handle clicks differently, such as when to fire off or cancel the event | |
| * (like scrolling when the target is a button, or holding a button down). | |
| * For browsers that already remove the 300ms delay, consider Ionic's tap system as a way to | |
| * normalize how clicks are handled across the various devices so there's an expected response | |
| * no matter what the device, platform or version. Additionally, Ionic will prevent | |
| * ghostclicks which even browsers that remove the delay still experience. | |
| * | |
| * In some cases, third-party libraries may also be working with touch events which can interfere | |
| * with the tap system. For example, mapping libraries like Google or Leaflet Maps often implement | |
| * a touch detection system which conflicts with Ionic's tap system. | |
| * | |
| * ### Disabling the tap system | |
| * | |
| * To disable the tap for an element and all of its children elements, | |
| * add the attribute `data-tap-disabled="true"`. | |
| * | |
| * ```html | |
| * <div data-tap-disabled="true"> | |
| * <div id="google-map"></div> | |
| * </div> | |
| * ``` | |
| * | |
| * ### Additional Notes: | |
| * | |
| * - Ionic tap works with Ionic's JavaScript scrolling | |
| * - Elements can come and go from the DOM and Ionic tap doesn't keep adding and removing | |
| * listeners | |
| * - No "tap delay" after the first "tap" (you can tap as fast as you want, they all click) | |
| * - Minimal events listeners, only being added to document | |
| * - Correct focus in/out on each input type (select, textearea, range) on each platform/device | |
| * - Shows and hides virtual keyboard correctly for each platform/device | |
| * - Works with labels surrounding inputs | |
| * - Does not fire off a click if the user moves the pointer too far | |
| * - Adds and removes an 'activated' css class | |
| * - Multiple [unit tests](https://github.com/driftyco/ionic/blob/master/test/unit/utils/tap.unit.js) for each scenario | |
| * | |

| IONIC TAP | |
| --------------- | |
| - Both touch and mouse events are added to the document.body on DOM ready | |
| - If a touch event happens, it does not use mouse event listeners | |
| - On touchend, if the distance between start and end was small, trigger a click | |
| - In the triggered click event, add a 'isIonicTap' property | |
| - The triggered click receives the same x,y coordinates as as the end event | |
| - On document.body click listener (with useCapture=true), only allow clicks with 'isIonicTap' | |
| - Triggering clicks with mouse events work the same as touch, except with mousedown/mouseup | |
| - Tapping inputs is disabled during scrolling | |

| /** | |
| * @ngdoc page | |
| * @name keyboard | |
| * @module ionic | |
| * @description | |
| * On both Android and iOS, Ionic will attempt to prevent the keyboard from | |
| * obscuring inputs and focusable elements when it appears by scrolling them | |
| * into view. In order for this to work, any focusable elements must be within | |
| * a [Scroll View](http://ionicframework.com/docs/api/directive/ionScroll/) | |
| * or a directive such as [Content](http://ionicframework.com/docs/api/directive/ionContent/) | |
| * that has a Scroll View. | |
| * | |
| * It will also attempt to prevent the native overflow scrolling on focus, | |
| * which can cause layout issues such as pushing headers up and out of view. | |
| * | |
| * The keyboard fixes work best in conjunction with the | |
| * [Ionic Keyboard Plugin](https://github.com/driftyco/ionic-plugins-keyboard), | |
| * although it will perform reasonably well without. However, if you are using | |
| * Cordova there is no reason not to use the plugin. | |
| * | |
| * ### Hide when keyboard shows | |
| * | |
| * To hide an element when the keyboard is open, add the class `hide-on-keyboard-open`. | |
| * | |
| * ```html | |
| * <div class="hide-on-keyboard-open"> | |
| * <div id="google-map"></div> | |
| * </div> | |
| * ``` | |
| * ---------- | |
| * | |
| * ### Plugin Usage | |
| * Information on using the plugin can be found at | |
| * [https://github.com/driftyco/ionic-plugins-keyboard](https://github.com/driftyco/ionic-plugins-keyboard). | |
| * | |
| * ---------- | |
| * | |
| * ### Android Notes | |
| * - If your app is running in fullscreen, i.e. you have | |
| * `<preference name="Fullscreen" value="true" />` in your `config.xml` file | |
| * you will need to set `ionic.Platform.isFullScreen = true` manually. | |
| * | |
| * - You can configure the behavior of the web view when the keyboard shows by setting | |
| * [android:windowSoftInputMode](http://developer.android.com/reference/android/R.attr.html#windowSoftInputMode) | |
| * to either `adjustPan`, `adjustResize` or `adjustNothing` in your app's | |
| * activity in `AndroidManifest.xml`. `adjustResize` is the recommended setting | |
| * for Ionic, but if for some reason you do use `adjustPan` you will need to | |
| * set `ionic.Platform.isFullScreen = true`. | |
| * | |
| * ```xml | |
| * <activity android:windowSoftInputMode="adjustResize"> | |
| * | |
| * ``` | |
| * | |
| * ### iOS Notes | |
| * - If the content of your app (including the header) is being pushed up and | |
| * out of view on input focus, try setting `cordova.plugins.Keyboard.disableScroll(true)`. | |
| * This does **not** disable scrolling in the Ionic scroll view, rather it | |
| * disables the native overflow scrolling that happens automatically as a | |
| * result of focusing on inputs below the keyboard. | |

| * @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. | |
| * | |
| * 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. | |
| * | |
| * 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.$injector} when the application is bootstrapped and | |
| * should contain the application code needed or have dependencies on other modules that will | |
| * contain the code. See {@link angular.module} for more information. | |
| * | |
| * In the example below if the `ngApp` directive were not placed on the `html` element then the | |
| * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}` | |
| * would not be resolved to `3`. | |
| * | |
| * `ngApp` is the easiest, and most common, way to bootstrap an application. | |
| * | |
| <example module="ngAppDemo"> | |
| <file name="index.html"> | |
| <div ng-controller="ngAppDemoController"> | |
| I can add: {{a}} + {{b}} = {{ a+b }} | |
| </div> | |
| </file> | |
| <file name="script.js"> | |
| angular.module('ngAppDemo', []).controller('ngAppDemoController', function($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) | |
| </p> | |
| </div> | |
| <div ng-controller="GoodController2"> | |
| Name: <input ng-model="name"><br /> | |
| Hello, {{name}}! | |
| <p>This renders because the controller does not fail to | |
| instantiate, by using explicit annotation style | |
| (see script.js for details) | |
| </p> | |
| </div> | |
| <div ng-controller="BadController"> | |
| I can add: {{a}} + {{b}} = {{ a+b }} | |
| <p>The controller could not be instantiated, due to relying | |
| on automatic function annotations (which are disabled in | |
| strict mode). As such, the content of this section is not | |
| interpolated, and there should be an error in your web console. | |

| * @description | |
| * | |
| * 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. | |
| * | |
| * When passed two or more arguments, a new module is created. If passed only one argument, an | |
| * existing module (the name passed as the first argument to `module`) is retrieved. | |
| * | |
| * | |
| * # 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 {module} new module with the {@link angular.Module} api. | |

| * 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." | |
| * | |
| * <div class="alert alert-success">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.</div> | |
| * | |
| * To use jQuery, simply load it before `DOMContentLoaded` event fired. | |
| * | |
| * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or | |
| * jqLite; they are never raw DOM references.</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/) | |

| * ## 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. | |
| * - `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. | |
| * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top | |
| * parent element is reached. | |
| * | |
| * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. | |
| * @returns {Object} jQuery object. | |

| * Sometimes you want to get access to the injector of a currently running Angular app | |

| * `$injector` is used to retrieve object instances as defined by | |
| * {@link auto.$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 | |
| * $injector.invoke(['serviceA', function(serviceA){}]); | |
| * ``` | |
| * | |
| * ## Inference | |
| * | |
| * In JavaScript calling `toString()` on a function returns the function definition. The definition | |
| * can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with | |
| * minification, and obfuscation tools since these tools change the argument names. | |
| * | |
| * ## `$inject` Annotation | |
| * By adding an `$inject` property onto a function the injection parameters can be specified. | |

| * ## Inline | |

| * @name $injector#annotate | |
| * | |
| * @description | |
| * Returns an array of service names which the function is requesting for injection. This API is | |
| * used by the injector to determine which services need to be injected into the function when the | |
| * function is invoked. There are three ways in which the function can be annotated with the needed | |
| * dependencies. | |
| * | |
| * # Argument names | |
| * | |
| * The simplest form is to extract the dependencies from the arguments of the function. This is done | |
| * by converting the function into a string using `toString()` method and extracting the argument | |
| * names. | |
| * ```js | |
| * // Given | |
| * function MyController($scope, $route) { | |
| * // ... | |
| * } | |
| * | |
| * // Then | |
| * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); | |
| * ``` | |
| * | |
| * This method does not work with code minification / obfuscation. For this reason the following | |
| * annotation strategies are supported. | |
| * | |
| * # The `$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. | |
| * | |
| * @returns {Array.<string>} The names of the services which the function requires. | |

| * {@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** | |

| * | |

| * 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, not providers. | |
| * * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`, | |
| * that will be wrapped in a **service provider** object, whose `$get` property will contain the | |
| * given factory function. | |
| * * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class` | |

| * 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 $injector.instantiate()}, then treated as `object`. | |
| * | |
| * @returns {Object} registered provider instance | |
| * @example | |
| * | |
| * The following example shows how to create a simple event tracking service and register it using | |
| * {@link auto.$provide#provider $provide.provider()}. | |
| * | |
| * ```js | |
| * // Define the eventTracker provider | |
| * function EventTrackerProvider() { | |
| * var trackingUrl = '/track'; | |
| * | |
| * // A provider method for configuring where the tracked events should been saved | |
| * this.setTrackingUrl = function(url) { | |
| * trackingUrl = url; | |
| * }; | |

| * // The service factory function | |
| * this.$get = ['$http', function($http) { | |

| * [Html5 spec](http://dev.w3.org/html5/spec/Overview.html#the-indicated-part-of-the-document). | |
| * | |
| * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to | |
| * match any anchor whenever it changes. This can be disabled by calling | |
| * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}. | |
| * | |
| * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a | |
| * vertical scroll-offset (either fixed or dynamic). | |
| * | |
| * @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 /> | |

| * ## 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: 'stringAlias', | |
| * 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. | |

| * var myModule = angular.module(...); | |
| * | |
| * myModule.directive('directiveName', function factory(injectables) { | |
| * var directiveDefinitionObject = { | |
| * link: function postLink(scope, iElement, iAttrs) { ... } | |
| * }; | |
| * return directiveDefinitionObject; | |
| * // or | |
| * // return function postLink(scope, iElement, iAttrs) { ... } | |
| * }); | |
| * ``` | |
| * | |
| * | |
| * | |
| * ### 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 recomended that this feature be used on directives | |
| * which are not strictly behavioural (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` | |
| * **If set to `true`,** then a new scope will be created for this directive. 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. | |
| * | |
| * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from | |
| * normal scope in that it does not prototypically inherit from the parent scope. This is useful | |
| * when creating reusable components, which should not accidentally read or modify data in the | |
| * parent scope. | |
| * | |
| * The 'isolate' scope takes an object hash which defines a set of local scope properties | |
| * derived from the parent scope. These local properties are useful for aliasing values for | |
| * templates. Locals definition is a hash of local scope property to its source: | |
| * | |
| * * `@` 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 `<widget my-attr="hello {{name}}">` and widget definition | |
| * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect | |
| * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the | |
| * `localName` property on the widget scope. The `name` is read from the parent scope (not | |
| * component scope). | |
| * | |
| * * `=` or `=attr` - set up bi-directional binding between a local scope property and the | |
| * parent scope property of name defined via the value of the `attr` attribute. If no `attr` | |
| * name is specified then the attribute name is assumed to be the same as the local name. | |
| * Given `<widget my-attr="parentModel">` and widget definition of | |
| * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the | |
| * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected | |
| * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent | |
| * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You | |
| * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If | |
| * you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use | |
| * `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional). | |
| * | |
| * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. | |
| * If no `attr` name is specified then the attribute name is assumed to be the same as the | |
| * local name. Given `<widget my-attr="count = count + value">` and widget definition of | |
| * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to | |
| * a function wrapper for the `count = count + value` expression. Often it's desirable to | |
| * pass data from the isolated scope via an expression to the parent scope, this can be | |
| * done by passing a map of local variable names and values into the expression wrapper fn. | |
| * For example, if the expression is `increment(amount)` then we can specify the amount value | |
| * by calling the `localFn` as `localFn({amount: 22})`. | |
| * | |
| * | |
| * #### `bindToController` | |
| * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController` will | |
| * allow a component to have its properties bound to the controller, rather than to scope. When the controller | |
| * is instantiated, the initial values of the isolate scope bindings are already available. | |
| * | |
| * #### `controller` | |
| * Controller constructor function. The controller is instantiated before the | |
| * pre-linking phase and it is shared with other directives (see | |
| * `require` attribute). This allows the directives to communicate with each other and augment | |
| * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: | |
| * | |
| * * `$scope` - Current scope associated with the element | |
| * * `$element` - Current element | |
| * * `$attrs` - Current attributes object for the element | |
| * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: | |
| * `function([scope], cloneLinkingFn, futureParentElement)`. | |
| * * `scope`: optional argument to override the scope. | |
| * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content. | |
| * * `futureParentElement`: | |
| * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. | |
| * * default: `$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. | |
| * | |
| * | |
| * #### `require` | |
| * Require another directive and inject its controller as the fourth argument to the linking function. The | |
| * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the | |
| * injected argument will be an array in corresponding order. If no such directive can be | |
| * found, or if the directive does not have a controller, then an error is raised. 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` | |
| * Controller alias at the directive scope. An alias for the controller so it | |
| * can be referenced at the directive template. The directive needs to define a scope for this | |
| * configuration to be used. Useful in the case when directive is used as component. | |
| * | |
| * | |
| * #### `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. | |
| * | |
| * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the | |
| * directive's element or the entire element: | |
| * | |
| * * `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. | |
| * | |
| * | |
| * #### `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 a | |
| * stack overflow errors. | |
| * | |
| * This can be avoided by manually using $compile in the postLink function to imperatively compile | |
| * a directive's template instead of relying on automatic template compilation via `template` or | |
| * `templateUrl` declaration or manual compilation inside the compile function. | |
| * </div> | |
| * | |
| * <div class="alert alert-error"> | |
| * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it | |
| * e.g. does not know about the right outer scope. Please use the transclude function that is passed | |
| * to the link function instead. | |
| * </div> | |
| * A compile function can have a return value which can be either a function or an object. | |
| * | |
| * * returning a (post-link) function - is equivalent to registering the linking function via the | |
| * `link` property of the config object when the compile function is empty. | |
| * | |
| * * returning an object with function(s) registered via `pre` and `post` properties - allows you to | |
| * control when a linking function should be called during the linking phase. See info about | |
| * pre-linking and post-linking functions below. | |
| * | |
| * | |
| * #### `link` | |
| * This property is used only if the `compile` property is not defined. | |
| * | |
| * ```js | |
| * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } | |
| * ``` | |
| * | |
| * The link function is responsible for registering DOM listeners as well as updating the DOM. It is | |
| * executed after the template has been cloned. This is where most of the directive logic will be | |
| * put. | |
| * | |
| * * `scope` - {@link ng.$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` - a controller instance - A controller instance if at least one directive on the | |
| * element defines a controller. The controller is shared among all the directives, which allows | |
| * the directives to use the controllers as a communication channel. | |
| * | |
| * * `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 element 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> | |
| * | |
| * #### 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 translude 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 and calling `element.remove()` to remove it), | |
| * then you are also responsible for calling `$destroy` on the transclusion scope. | |
| * </div> | |
| * | |
| * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} | |
| * automatically destroy their transluded clones as necessary so you do not need to worry about this if | |
| * you are simply using {@link ngTransclude} to inject the transclusion into your directive. | |
| * | |
| * | |
| * #### Transclusion Scopes | |
| * | |
| * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion | |
| * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed | |
| * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it | |
| * was taken. | |
| * | |
| * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look | |
| * like this: | |
| * | |
| * ```html | |
| * <div ng-app> | |
| * <div isolate> | |
| * <div transclusion> | |
| * </div> | |
| * </div> | |
| * </div> | |
| * ``` | |
| * | |
| * The `$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. | |

| * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it | |

| * `parentBoundTranscludeFn` to the link function instead. | |
| * </div> | |
| * | |
| * @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 controller instances; if given, it will make the controllers | |
| * available to directives. | |
| * * `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 | |
| * 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 configuration object — | |
| * that is used to generate an HTTP request and returns a {@link ng.$q promise} | |
| * with two $http specific methods: `success` and `error`. | |
| * | |
| * ```js | |
| * // Simple GET request example : | |
| * $http.get('/someUrl'). | |
| * success(function(data, status, headers, config) { | |
| * // this callback will be called asynchronously | |
| * // when the response is available | |
| * }). | |
| * error(function(data, status, headers, config) { | |
| * // called asynchronously if an error occurs | |
| * // or server returns response with an error status. | |
| * }); | |
| * ``` | |
| * | |
| * ```js | |
| * // Simple POST request example (passing data) : | |
| * $http.post('/someUrl', {msg:'hello word!'}). | |
| * success(function(data, status, headers, config) { | |
| * // this callback will be called asynchronously | |
| * // when the response is available | |
| * }). | |
| * error(function(data, status, headers, config) { | |
| * // called asynchronously if an error occurs | |
| * // or server returns response with an error status. | |
| * }); | |
| * ``` | |
| * | |
| * | |
| * Since the returned value of calling the $http function is a `promise`, you can also use | |
| * the `then` method to register callbacks, and these callbacks will receive a single argument – | |
| * an object representing the response. See the API signature and type info below for more | |
| * details. | |
| * | |
| * A response status code between 200 and 299 is considered a success status and | |
| * will result in the success callback being called. Note that if the response is a redirect, | |
| * XMLHttpRequest will transparently follow it, meaning that the error callback will not be | |
| * called for such responses. | |
| * | |
| * ## 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(); | |
| * ``` | |
| * | |
| * ## 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. | |
| * | |
| * ```js | |
| * $http.get('/someUrl').success(successCallback); | |
| * $http.post('/someUrl', data).success(successCallback); | |
| * ``` | |
| * | |
| * Complete list of shortcut methods: | |
| * | |
| * - {@link ng.$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} | |
| * | |
| * | |
| * ## 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. | |
| * | |
| * | |
| * ## 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)`) or an array of such transformation functions, | |
| * which allows you to `push` or `unshift` a new transformation function into the transformation chain. | |
| * | |
| * ### 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 | |
| * | |
| * To enable caching, set the request configuration `cache` property to `true` (to use default | |
| * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}). | |
| * When the cache is enabled, `$http` stores the response from the server in the specified | |
| * cache. The next time the same request is made, the response is served from the cache without | |
| * sending a request to the server. | |
| * | |
| * Note that even if the response is served from cache, delivery of the data is asynchronous in | |
| * the same way that real requests are. | |
| * | |
| * If there are multiple GET requests for the same URL that should be cached using the same | |
| * cache, but the cache is not populated yet, only one request to the server will be made and | |
| * the remaining requests will be fulfilled using the response from the first request. | |
| * | |
| * You can change the default cache to a new object (built with | |
| * {@link ng.$cacheFactory `$cacheFactory`}) by updating the | |
| * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set | |
| * their `cache` property to `true` will now use this cache object. | |
| * | |
| * If you set the default cache to `false` then only requests that specify their own custom | |
| * cache object will be cached. | |
| * | |
| * ## Interceptors | |
| * | |
| * Before you start creating interceptors, be sure to understand the | |
| * {@link ng.$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 `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 a technique by which | |
| * an unauthorized site can gain your user's private data. 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. | |
| * | |
| * | |
| * @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 turned | |
| * to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be | |
| * JSONified. | |
| * - **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. | |
| * - **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 #overriding-the-default-transformations-per-request Overriding the Default Transformations} | |
| * - **transformResponse** – | |
| * `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – | |
| * transform function or an array of such functions. The transform function takes the http | |
| * response body and headers and returns its transformed (typically deserialized) version. | |
| * See {@link #overriding-the-default-transformations-per-request Overriding the Default Transformations} | |
| * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the | |
| * GET request, otherwise if a cache instance built with | |
| * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for | |
| * caching. | |
| * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$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) | |
| * for more information. | |
| * - **responseType** - `{string}` - see | |
| * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType). | |
| * | |
| * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the | |
| * standard `then` method and two http specific methods: `success` and `error`. The `then` | |
| * method takes two arguments a success and an error callback which will be called with a | |
| * response object. The `success` and `error` methods take a single argument - a function that | |
| * will be called when the request succeeds or fails respectively. The arguments passed into | |
| * these functions are destructured representation of the response object passed into the | |
| * `then` method. 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. | |
| * | |
| * @property {Array.<Object>} pendingRequests Array of config objects for currently pending | |
| * requests. This is primarily meant to be used for debugging purposes. | |
| * | |

| * @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 $compile}, or otherwise interpolated with the `mustHaveExpression` parameter | |
| * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, | |
| * this is typically useful only when user-data is used in rendering a template from the server, or | |
| * when otherwise untrusted data is used by a directive. | |
| * | |
| * <example> | |
| * <file name="index.html"> | |
| * <div ng-init="username='A user'"> | |
| * <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\} | |
| * </p> | |
| * <p><strong>{{username}}</strong> attempts to inject code which will deface the | |
| * application, but fails to accomplish their task, because the server has correctly | |
| * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash) | |
| * characters.</p> | |
| * <p>Instead, the result of the attempted script injection is visible, and can be removed | |
| * from the database by an administrator.</p> | |
| * </div> | |
| * </file> | |
| * </example> | |
| * | |
| * @param {string} text The text with markup to interpolate. | |
| * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have | |
| * embedded expression in order to return an interpolation function. Strings with no | |
| * embedded expression will return null for the interpolation function. | |
| * @param {string=} trustedContext when provided, the returned function passes the interpolated | |
| * result through {@link ng.$sce#getTrusted $sce.getTrusted(interpolatedResult, | |
| * trustedContext)} before returning it. Refer to the {@link ng.$sce $sce} service that | |
| * provides Strict Contextual Escaping for details. | |
| * @param {boolean=} allOrNothing if `true`, then the returned function returns undefined | |
| * unless all embedded expressions evaluate to a value other than `undefined`. | |

| // 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. | |

| /** | |
| * @ngdoc service | |
| * @name $q | |
| * @requires $rootScope | |
| * | |
| * @description | |
| * A promise/deferred implementation 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 promises to some degree. | |
| * | |
| * # $q constructor | |
| * | |
| * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver` | |
| * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony, | |
| * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). | |
| * | |
| * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are | |
| * available yet. | |
| * | |
| * It can be used like so: | |
| * | |
| * ```js | |
| * // for the purpose of this example let's assume that variables `$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 $q(function(resolve, reject) { | |
| * setTimeout(function() { | |
| * if (okToGreet(name)) { | |
| * resolve('Hello, ' + name + '!'); | |
| * } else { | |
| * reject('Greeting ' + name + ' is not allowed.'); | |
| * } | |
| * }, 1000); | |
| * }); | |
| * } | |
| * | |
| * var promise = asyncGreet('Robin Hood'); | |
| * promise.then(function(greeting) { | |
| * alert('Success: ' + greeting); | |
| * }, function(reason) { | |
| * alert('Failed: ' + reason); | |
| * }); | |
| * ``` | |
| * | |
| * Note: progress/notify callbacks are not currently supported via the ES6-style interface. | |
| * | |
| * However, the more traditional CommonJS-style usage is still available, and documented below. | |
| * | |
| * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an | |
| * interface for interacting with an object that represents the result of an action that is | |
| * performed asynchronously, and may or may not be finished at any given point in time. | |
| * | |
| * From the perspective of dealing with error handling, deferred and promise APIs are to | |
| * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. | |
| * | |
| * ```js | |
| * // for the purpose of this example let's assume that variables `$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`. 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)` – 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. | |
| * | |
| * Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as | |
| * property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to | |
| * make your code IE8 and Android 2.x compatible. | |
| * | |
| * # 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 | |
| * models and avoiding unnecessary browser repaints, which would result in flickering UI. | |
| * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains | |
| * all the important functionality needed for common async tasks. | |
| * | |
| * # Testing | |
| * | |
| * ```js | |
| * it('should simulate promise', inject(function($q, $rootScope) { | |
| * var deferred = $q.defer(); | |
| * var promise = deferred.promise; | |
| * var resolvedValue; | |
| * | |
| * promise.then(function(value) { resolvedValue = value; }); | |
| * expect(resolvedValue).toBeUndefined(); | |
| * | |
| * // Simulate resolving of promise | |
| * deferred.resolve(123); | |
| * // Note that the 'then' function does not get called synchronously. | |
| * // This is because we want the promise API to always be async, whether or not | |
| * // it got called synchronously or asynchronously. | |
| * expect(resolvedValue).toBeUndefined(); | |
| * | |
| * // Propagate promise resolution to 'then' functions using $apply(). | |
| * $rootScope.$apply(); | |
| * expect(resolvedValue).toEqual(123); | |
| * })); | |
| * ``` | |
| * | |
| * @param {function(function, function)} resolver Function which is responsible for resolving or | |
| * rejecting the newly created promise. The first parameter is a function which resolves the | |
| * promise, the second parameter is a function which rejects the promise. | |
| * | |
| * @returns {Promise} The newly created promise. | |

| * `reject`. | |

| * 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 middle are expensive so we use linked list | |
| * | |
| * There are few watches then a lot of observers. This is why you don't want the observer to be | |
| * implemented in the same way as watch. Watch requires return of initialization function which | |
| * are 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 | |
| * $digest()} and should return the value that will be watched. (Since | |
| * {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the | |
| * `watchExpression` can execute multiple times per | |
| * {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.) | |
| * - The `listener` is called only when the value from the current `watchExpression` and the | |
| * previous call to `watchExpression` are not equal (with the exception of the initial run, | |
| * see below). Inequality is determined according to reference inequality, | |
| * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators) | |
| * via the `!==` Javascript operator, unless `objectEquality == true` | |
| * (see next point) | |
| * - When `objectEquality == true`, inequality of the `watchExpression` is determined | |
| * according to the {@link angular.equals} function. To save the value of the object for | |
| * later comparison, the {@link angular.copy} function is used. This therefore means that | |
| * watching complex objects will have adverse memory and performance implications. | |
| * - The watch `listener` may change the model, which may trigger other `listener`s to fire. | |
| * This is achieved by rerunning the watchers until no changes are detected. The rerun | |
| * iteration limit is 10 to prevent an infinite loop deadlock. | |
| * | |
| * | |
| * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called, | |
| * you can register a `watchExpression` function with no `listener`. (Since `watchExpression` | |
| * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a | |
| * change is detected, be prepared for multiple calls to your listener.) | |
| * | |
| * After a watcher is registered with the scope, the `listener` fn is called asynchronously | |
| * (via {@link ng.$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'; | |
| scope.counter = 0; | |

| // the listener is always called during the first $digest loop after it was registered | |
| expect(scope.counter).toEqual(1); | |
| scope.$digest(); | |
| // but now it will not be called unless the value changes | |
| expect(scope.counter).toEqual(1); | |
| scope.name = 'adam'; | |

| // Using a function as a watchExpression | |

| // This function returns the value being watched. It is called for each turn of the $digest loop | |
| function() { return food; }, | |
| // This is the change listener, called when the value returned from the above function changes | |
| function(newValue, oldValue) { | |
| if ( newValue !== oldValue ) { | |
| // Only increment the counter if the value changed | |
| scope.foodCounter = scope.foodCounter + 1; | |
| } | |
| } | |
| ); | |
| // No digest has been run so the counter will be zero | |

| * Shallow watches the properties of an object and fires whenever any of the properties change | |
| * (for arrays, this implies watching the array items; for object maps, this implies watching | |
| * the properties). If a change is detected, the `listener` callback is fired. | |
| * | |
| * - The `obj` collection is observed via standard $watch operation and is examined on every | |
| * call to $digest() to see if any items have been added, removed, or moved. | |
| * - The `listener` is called whenever anything within the `obj` has changed. Examples include | |
| * adding, removing, and moving items belonging to an object or array. | |
| * | |
| * | |
| * # Example | |
| * ```js | |
| $scope.names = ['igor', 'matias', 'misko', 'james']; | |
| $scope.dataCount = 4; | |
| $scope.$watchCollection('names', function(newNames, oldNames) { | |
| $scope.dataCount = newNames.length; | |
| }); | |
| expect($scope.dataCount).toEqual(4); | |
| $scope.$digest(); | |
| //still at 4 ... no changes | |
| expect($scope.dataCount).toEqual(4); | |
| $scope.names.pop(); | |
| $scope.$digest(); | |
| //now there's been a change | |
| expect($scope.dataCount).toEqual(3); | |
| * ``` | |
| * | |
| * | |
| * @param {string|function(scope)} obj Evaluated as {@link guide/expression expression}. The | |
| * expression value should evaluate to an object or an array which is observed on each | |
| * {@link ng.$rootScope.Scope#$digest $digest} cycle. Any shallow change within the | |
| * collection will trigger a call to the `listener`. | |
| * | |
| * @param {function(newCollection, oldCollection, scope)} listener a callback function called | |
| * when a change is detected. | |
| * - The `newCollection` object is the newly modified data obtained from the `obj` expression | |
| * - The `oldCollection` object is a copy of the former collection data. | |
| * Due to performance considerations, the`oldCollection` value is computed only if the | |
| * `listener` function declares two or more arguments. | |
| * - The `scope` argument refers to the current scope. | |
| * | |
| * @returns {function()} Returns a de-registration function for this listener. When the | |
| * de-registration function is executed, the internal watch operation is terminated. | |

| * @name $rootScope.Scope#$digest | |
| * @kind function | |
| * | |
| * @description | |
| * 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#$watch watchers} | |
| * until no more listeners are firing. This means that it is possible to get into an infinite | |
| * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of | |
| * iterations exceeds 10. | |
| * | |
| * Usually, you don't call `$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 $watch()} with no `listener`. | |
| * | |
| * In unit tests, you may need to call `$digest()` to simulate the scope life cycle. | |
| * | |
| * # Example | |
| * ```js | |
| var scope = ...; | |
| scope.name = 'misko'; | |
| scope.counter = 0; | |
| expect(scope.counter).toEqual(0); | |
| scope.$watch('name', function(newValue, oldValue) { | |
| scope.counter = scope.counter + 1; | |
| }); | |
| expect(scope.counter).toEqual(0); | |
| scope.$digest(); | |
| // the listener is always called during the first $digest loop after it was registered | |
| expect(scope.counter).toEqual(1); | |
| scope.$digest(); | |
| // but now it will not be called unless the value changes | |
| expect(scope.counter).toEqual(1); | |

| * | |
| * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of | |

| * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to | |

| * 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 app is hosted at url `http://myapp.example.com/` | |

| * - and you have an open redirect at `http://myapp.example.com/clickThru?...`. | |

| * | |
| * # 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 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"> | |
| * <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 | |
| * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or | |
| * protocols, you may either either {@link ng.$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.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. | |
| * | |
| * This significantly reduces the overhead. It is far easier to pay the small overhead and have an | |
| * application that's secure and can be audited to verify that with much more ease than bolting | |
| * security onto an application later. | |
| * | |
| * <a name="contexts"></a> | |
| * ## What trusted context types are supported? | |
| * | |
| * | Context | Notes | | |
| * |---------------------|----------------| | |
| * | `$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 | |
| * not appropriate to use in for 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 | |
| * if they 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. | |
| * | |

| * <b>User comments</b><br> | |
| * 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 >= 8 and <= 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. | |
| * | |
| * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one | |
| * uses the inner HTML approach to assign the URL as part of an HTML snippet - | |
| * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL. | |
| * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception. | |
| * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that | |
| * method and IE < 8 is unsupported. | |

| * annotated with dependencies and is responsible for creating a filter function. | |
| * | |
| * ```js | |
| * // Filter registration | |
| * function MyModule($provide, $filterProvider) { | |
| * // create a service to demonstrate injection (not always needed) | |
| * $provide.value('greet', function(name){ | |
| * return 'Hello ' + name + '!'; | |
| * }); | |
| * | |
| * // register a filter factory which uses the | |
| * // greet service to demonstrate DI. | |
| * $filterProvider.register('greet', function(greet){ | |
| * // return the filter function which uses the greet service | |
| * // to generate salutation | |
| * return function(text) { | |
| * // filters need to be forgiving so check input validity | |
| * return text && greet(text) || text; | |
| * }; | |
| * }); | |
| * } | |
| * ``` | |
| * | |
| * The filter function is registered with the `$injector` under the filter name suffix with | |
| * `Filter`. | |
| * | |
| * ```js | |
| * it('should be the same instance', inject( | |
| * function($filterProvider) { | |
| * $filterProvider.register('reverse', function(){ | |
| * return ...; | |
| * }); | |
| * }, | |
| * function($filter, reverseFilter) { | |
| * expect($filter('reverse')).toBe(reverseFilter); | |
| * }); | |
| * ``` | |
| * | |
| * | |
| * For more information about how angular filters work, and how to create your own filters, see | |
| * {@link guide/filter Filters} in the Angular Developer Guide. | |

| * @ngdoc filter | |
| * @name 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 evaluated as an expression and the resulting value is used for substring match against | |
| * the contents of the `array`. All strings or objects with string properties in `array` that contain this string | |
| * will be returned. 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. 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". | |
| * | |
| * - `function(value, index)`: A predicate function can be used to write arbitrary filters. The | |
| * function is called for each element of `array`. 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 the item should be included in filtered result. | |
| * | |
| * - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`. | |
| * 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. | |

| * | |
| * @description | |
| * Formats `date` to a string based on the requested `format`. | |
| * | |
| * `format` string can be composed of the following elements: | |
| * | |
| * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010) | |
| * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10) | |
| * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199) | |
| * * `'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) | |
| * * `'dd'`: Day in month, padded (01-31) | |
| * * `'d'`: Day in month (1-31) | |
| * * `'EEEE'`: Day in Week,(Sunday-Saturday) | |
| * * `'EEE'`: Day in Week, (Sun-Sat) | |
| * * `'HH'`: Hour in day, padded (00-23) | |
| * * `'H'`: Hour in day (0-23) | |
| * * `'hh'`: Hour in AM/PM, padded (01-12) | |
| * * `'h'`: Hour in AM/PM, (1-12) | |
| * * `'mm'`: Minute in hour, padded (00-59) | |
| * * `'m'`: Minute in hour (0-59) | |
| * * `'ss'`: Second in minute, padded (00-59) | |
| * * `'s'`: Second in minute (0-59) | |
| * * `'.sss' or ',sss'`: Millisecond in second, padded (000-999) | |
| * * `'a'`: AM/PM marker | |
| * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200) | |
| * * `'ww'`: ISO-8601 week of year (00-53) | |
| * * `'w'`: ISO-8601 week of year (0-53) | |
| * | |
| * `format` string can also be one of the following predefined | |
| * {@link guide/i18n localizable formats}: | |
| * | |
| * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale | |
| * (e.g. Sep 3, 2010 12:05:08 PM) | |
| * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM) | |
| * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale | |
| * (e.g. Friday, September 3, 2010) | |
| * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010) | |
| * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010) | |
| * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10) | |
| * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM) | |
| * * `'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. Right now, only `'UTC'` is supported. | |
| * If not specified, the timezone of the browser will be used. | |
| * @returns {string} Formatted string or the input if input is not recognized as date/millis. | |

| * @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 | |
| * correctly, make sure they are actually being saved as numbers and not strings. | |
| * | |
| * @param {Array} array The array 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. | |

| * @name form | |
| * @restrict E | |
| * | |
| * @description | |
| * Directive that instantiates | |
| * {@link form.FormController FormController}. | |
| * | |
| * If the `name` attribute is specified, the form controller is published onto the current scope under | |
| * this name. | |
| * | |
| * # 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. This allows you to have nested forms, which is very useful when | |
| * using Angular validation directives in forms that are dynamically generated using the | |
| * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name` | |
| * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an | |
| * `ngForm` directive and nest these in an outer `form` element. | |
| * | |
| * | |
| * # CSS classes | |
| * - `ng-valid` is set if the form is valid. | |
| * - `ng-invalid` is set if the form is invalid. | |
| * - `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 into using CSS transitions, keyframes as well | |
| * as JS animations. | |
| * | |
| * The following example shows a simple way to utilize CSS transitions to style a form element | |
| * that has been rendered as invalid after it has been validated: | |
| * | |
| * <pre> | |
| * //be sure to include ngAnimate as a module to hook into more | |
| * //advanced animations | |
| * .my-form { | |
| * transition:0.5s linear all; | |
| * background: white; | |
| * } | |
| * .my-form.ng-invalid { | |
| * background: red; | |
| * color:white; | |
| * } | |
| * </pre> | |
| * | |
| * @example | |

| * @name input[email] | |
| * | |
| * @description | |
| * Text input with email validation. Sets the `email` validation error key if not a valid email | |
| * address. | |
| * | |
| * <div class="alert alert-warning"> | |
| * **Note:** `input[email]` uses a regex to validate email addresses that is derived from the regex | |
| * used in Chromium. If you need stricter validation (e.g. requiring a top-level domain), you can | |
| * use `ng-pattern` or modify the built-in validators (see the {@link guide/forms Forms guide}) | |
| * </div> | |
| * | |
| * @param {string} ngModel Assignable angular expression to data-bind to. | |
| * @param {string=} name Property name of the form under which the control is published. | |
| * @param {string=} required Sets `required` validation error key if the value is not entered. | |
| * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to | |
| * the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of | |
| * `required` when you want to data-bind to the `required` attribute. | |
| * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than | |
| * minlength. | |
| * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than | |
| * maxlength. | |
| * @param {string=} ngPattern Sets `pattern` validation error key if the value does not match the | |
| * RegExp pattern expression. Expected value is `/regexp/` for inline patterns or `regexp` for | |
| * patterns defined as scope expressions. | |
| * @param {string=} ngChange Angular expression to be executed when input changes due to user | |
| * interaction with the input element. | |
