/** | |
* Directives allow you to attach behavior to elements in the DOM. | |
* | |
* <a href='/angular2/annotations/Directive'><code>Directive</code></a>s with an embedded view are called <a href='/angular2/angular2/Component'><code>Component</code></a>s. | |
* | |
* A directive consists of a single directive annotation and a controller class. When the | |
* directive's `selector` matches | |
* elements in the DOM, the following steps occur: | |
* | |
* 1. For each directive, the `ElementInjector` attempts to resolve the directive's constructor | |
* arguments. | |
* 2. Angular instantiates directives for each matched element using `ElementInjector` in a | |
* depth-first order, | |
* as declared in the HTML. | |
* | |
* ## Understanding How Injection Works | |
* | |
* There are three stages of injection resolution. | |
* - *Pre-existing Injectors*: | |
* - The terminal <a href='/angular2/angular2/Injector'><code>Injector</code></a> cannot resolve dependencies. It either throws an error or, if | |
* the dependency was | |
* specified as `@Optional`, returns `null`. | |
* - The platform injector resolves browser singleton resources, such as: cookies, title, | |
* location, and others. | |
* - *Component Injectors*: Each component instance has its own <a href='/angular2/angular2/Injector'><code>Injector</code></a>, and they follow | |
* the same parent-child hierarchy | |
* as the component instances in the DOM. | |
* - *Element Injectors*: Each component instance has a Shadow DOM. Within the Shadow DOM each | |
* element has an `ElementInjector` | |
* which follow the same parent-child hierarchy as the DOM elements themselves. | |
* | |
* When a template is instantiated, it also must instantiate the corresponding directives in a | |
* depth-first order. The | |
* current `ElementInjector` resolves the constructor dependencies for each directive. | |
* | |
* Angular then resolves dependencies as follows, according to the order in which they appear in the | |
* <a href='/angular2/angular2/View'><code>View</code></a>: | |
* | |
* 1. Dependencies on the current element | |
* 2. Dependencies on element injectors and their parents until it encounters a Shadow DOM boundary | |
* 3. Dependencies on component injectors and their parents until it encounters the root component | |
* 4. Dependencies on pre-existing injectors | |
* | |
* | |
* The `ElementInjector` can inject other directives, element-specific special objects, or it can | |
* delegate to the parent | |
* injector. | |
* | |
* To inject other directives, declare the constructor parameter as: | |
* - `directive:DirectiveType`: a directive on the current element only | |
* - `@Ancestor() directive:DirectiveType`: any directive that matches the type between the current | |
* element and the | |
* Shadow DOM root. Current element is not included in the resolution, therefore even if it could | |
* resolve it, it will | |
* be ignored. | |
* - `@Parent() directive:DirectiveType`: any directive that matches the type on a direct parent | |
* element only. | |
* - `@Query(DirectiveType) query:QueryList<DirectiveType>`: A live collection of direct child | |
* directives. | |
* - `@QueryDescendants(DirectiveType) query:QueryList<DirectiveType>`: A live collection of any | |
* child directives. | |
* | |
* To inject element-specific special objects, declare the constructor parameter as: | |
* - `element: ElementRef` to obtain a reference to logical element in the view. | |
* - `viewContainer: ViewContainerRef` to control child template instantiation, for | |
* <a href='/angular2/annotations/Directive'><code>Directive</code></a> directives only | |
* - `bindingPropagation: BindingPropagation` to control change detection in a more granular way. | |
* | |
* ## Example | |
* | |
* The following example demonstrates how dependency injection resolves constructor arguments in | |
* practice. | |
* | |
* | |
* Assume this HTML template: | |
* | |
* ``` | |
* <div dependency="1"> | |
* <div dependency="2"> | |
* <div dependency="3" my-directive> | |
* <div dependency="4"> | |
* <div dependency="5"></div> | |
* </div> | |
* <div dependency="6"></div> | |
* </div> | |
* </div> | |
* </div> | |
* ``` | |
* | |
* With the following `dependency` decorator and `SomeService` injectable class. | |
* | |
* ``` | |
* @Injectable() | |
* class SomeService { | |
* } | |
* | |
* @Directive({ | |
* selector: '[dependency]', | |
* properties: [ | |
* 'id: dependency' | |
* ] | |
* }) | |
* class Dependency { | |
* id:string; | |
* } | |
* ``` | |
* | |
* Let's step through the different ways in which `MyDirective` could be declared... | |
* | |
* | |
* ### No injection | |
* | |
* Here the constructor is declared with no arguments, therefore nothing is injected into | |
* `MyDirective`. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor() { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with no dependencies. | |
* | |
* | |
* ### Component-level injection | |
* | |
* Directives can inject any injectable instance from the closest component injector or any of its | |
* parents. | |
* | |
* Here, the constructor declares a parameter, `someService`, and injects the `SomeService` type | |
* from the parent | |
* component's injector. | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(someService: SomeService) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a dependency on `SomeService`. | |
* | |
* | |
* ### Injecting a directive from the current element | |
* | |
* Directives can inject other directives declared on the current element. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(dependency: Dependency) { | |
* expect(dependency.id).toEqual(3); | |
* } | |
* } | |
* ``` | |
* This directive would be instantiated with `Dependency` declared at the same element, in this case | |
* `dependency="3"`. | |
* | |
* | |
* ### Injecting a directive from a direct parent element | |
* | |
* Directives can inject other directives declared on a direct parent element. By definition, a | |
* directive with a | |
* `@Parent` annotation does not attempt to resolve dependencies for the current element, even if | |
* this would satisfy | |
* the dependency. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Parent() dependency: Dependency) { | |
* expect(dependency.id).toEqual(2); | |
* } | |
* } | |
* ``` | |
* This directive would be instantiated with `Dependency` declared at the parent element, in this | |
* case `dependency="2"`. | |
* | |
* | |
* ### Injecting a directive from any ancestor elements | |
* | |
* Directives can inject other directives declared on any ancestor element (in the current Shadow | |
* DOM), i.e. on the | |
* parent element and its parents. By definition, a directive with an `@Ancestor` annotation does | |
* not attempt to | |
* resolve dependencies for the current element, even if this would satisfy the dependency. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Ancestor() dependency: Dependency) { | |
* expect(dependency.id).toEqual(2); | |
* } | |
* } | |
* ``` | |
* | |
* Unlike the `@Parent` which only checks the parent, `@Ancestor` checks the parent, as well as its | |
* parents recursively. If `dependency="2"` didn't exist on the direct parent, this injection would | |
* have returned | |
* `dependency="1"`. | |
* | |
* | |
* ### Injecting a live collection of direct child directives | |
* | |
* | |
* A directive can also query for other child directives. Since parent directives are instantiated | |
* before child directives, a directive can't simply inject the list of child directives. Instead, | |
* the directive injects a <a href='QueryList'>QueryList</a>, which updates its contents as children are added, | |
* removed, or moved by a directive that uses a <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> such as a `ng-for`, an | |
* `ng-if`, or an `ng-switch`. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Query(Dependency) dependencies:QueryList<Dependency>) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a <a href='QueryList'>QueryList</a> which contains `Dependency` 4 and | |
* 6. Here, `Dependency` 5 would not be included, because it is not a direct child. | |
* | |
* ### Injecting a live collection of descendant directives | |
* | |
* Note: This is will be implemented in later release. () | |
* | |
* Similar to `@Query` above, but also includes the children of the child elements. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@QueryDescendents(Dependency) dependencies:QueryList<Dependency>) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a Query which would contain `Dependency` 4, 5 and 6. | |
* | |
* ### Optional injection | |
* | |
* The normal behavior of directives is to return an error when a specified dependency cannot be | |
* resolved. If you | |
* would like to inject `null` on unresolved dependency instead, you can annotate that dependency | |
* with `@Optional()`. | |
* This explicitly permits the author of a template to treat some of the surrounding directives as | |
* optional. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Optional() dependency:Dependency) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a `Dependency` directive found on the current element. | |
* If none can be | |
* found, the injector supplies `null` instead of throwing an error. | |
* | |
* ## Example | |
* | |
* Here we use a decorator directive to simply define basic tool-tip behavior. | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[tooltip]', | |
* properties: [ | |
* 'text: tooltip' | |
* ], | |
* hostListeners: { | |
* 'onmouseenter': 'onMouseEnter()', | |
* 'onmouseleave': 'onMouseLeave()' | |
* } | |
* }) | |
* class Tooltip{ | |
* text:string; | |
* overlay:Overlay; // NOT YET IMPLEMENTED | |
* overlayManager:OverlayManager; // NOT YET IMPLEMENTED | |
* | |
* constructor(overlayManager:OverlayManager) { | |
* this.overlay = overlay; | |
* } | |
* | |
* onMouseEnter() { | |
* // exact signature to be determined | |
* this.overlay = this.overlayManager.open(text, ...); | |
* } | |
* | |
* onMouseLeave() { | |
* this.overlay.close(); | |
* this.overlay = null; | |
* } | |
* } | |
* ``` | |
* In our HTML template, we can then add this behavior to a `<div>` or any other element with the | |
* `tooltip` selector, | |
* like so: | |
* | |
* ``` | |
* <div tooltip="some text here"></div> | |
* ``` | |
* | |
* Directives can also control the instantiation, destruction, and positioning of inline template | |
* elements: | |
* | |
* A directive uses a <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> to instantiate, insert, move, and destroy views at | |
* runtime. | |
* The <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> is created as a result of `<template>` element, and represents a | |
* location in the current view | |
* where these actions are performed. | |
* | |
* Views are always created as children of the current <a href='/angular2/angular2/View'><code>View</code></a>, and as siblings of the | |
* `<template>` element. Thus a | |
* directive in a child view cannot inject the directive that created it. | |
* | |
* Since directives that create views via ViewContainers are common in Angular, and using the full | |
* `<template>` element syntax is wordy, Angular | |
* also supports a shorthand notation: `<li *foo="bar">` and `<li template="foo: bar">` are | |
* equivalent. | |
* | |
* Thus, | |
* | |
* ``` | |
* <ul> | |
* <li *foo="bar" title="text"></li> | |
* </ul> | |
* ``` | |
* | |
* Expands in use to: | |
* | |
* ``` | |
* <ul> | |
* <template [foo]="bar"> | |
* <li title="text"></li> | |
* </template> | |
* </ul> | |
* ``` | |
* | |
* Notice that although the shorthand places `*foo="bar"` within the `<li>` element, the binding for | |
* the directive | |
* controller is correctly instantiated on the `<template>` element rather than the `<li>` element. | |
* | |
* | |
* ## Example | |
* | |
* Let's suppose we want to implement the `unless` behavior, to conditionally include a template. | |
* | |
* Here is a simple directive that triggers on an `unless` selector: | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[unless]', | |
* properties: ['unless'] | |
* }) | |
* export class Unless { | |
* viewContainer: ViewContainerRef; | |
* protoViewRef: ProtoViewRef; | |
* prevCondition: boolean; | |
* | |
* constructor(viewContainer: ViewContainerRef, protoViewRef: ProtoViewRef) { | |
* this.viewContainer = viewContainer; | |
* this.protoViewRef = protoViewRef; | |
* this.prevCondition = null; | |
* } | |
* | |
* set unless(newCondition) { | |
* if (newCondition && (isBlank(this.prevCondition) || !this.prevCondition)) { | |
* this.prevCondition = true; | |
* this.viewContainer.clear(); | |
* } else if (!newCondition && (isBlank(this.prevCondition) || this.prevCondition)) { | |
* this.prevCondition = false; | |
* this.viewContainer.create(this.protoViewRef); | |
* } | |
* } | |
* } | |
* ``` | |
* | |
* We can then use this `unless` selector in a template: | |
* ``` | |
* <ul> | |
* <li *unless="expr"></li> | |
* </ul> | |
* ``` | |
* | |
* Once the directive instantiates the child view, the shorthand notation for the template expands | |
* and the result is: | |
* | |
* ``` | |
* <ul> | |
* <template [unless]="exp"> | |
* <li></li> | |
* </template> | |
* <li></li> | |
* </ul> | |
* ``` | |
* | |
* Note also that although the `<li></li>` template still exists inside the `<template></template>`, | |
* the instantiated | |
* view occurs on the second `<li></li>` which is a sibling to the `<template>` element. | |

* You can include a <a href='/angular2/angular2/Pipe'><code>Pipe</code></a> when specifying a `bindingProperty` to allow for data | |
* transformation and structural change detection of the value. These pipes will be evaluated in | |
* the context of this component. | |
* | |
* ## Syntax | |
* | |
* There is no need to specify both `directiveProperty` and `bindingProperty` when they both have | |
* the same value. | |
* | |
* ``` | |
* @Directive({ | |
* properties: [ | |
* 'propertyName', // shorthand notation for 'propertyName: propertyName' | |
* 'directiveProperty1: bindingProperty1', | |
* 'directiveProperty2: bindingProperty2 | pipe1 | ...', | |
* ... | |
* ] | |
* } | |
* ``` | |
* | |
* | |
* ## Basic Property Binding | |
* | |
* We can easily build a simple `Tooltip` directive that exposes a `tooltip` property, which can | |
* be used in templates with standard Angular syntax. For example: | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[tooltip]', | |
* properties: [ | |
* 'text: tooltip' | |
* ] | |
* }) | |
* class Tooltip { | |
* set text(value: string) { | |
* // This will get called every time with the new value when the 'tooltip' property changes | |
* } | |
* } | |
* ``` | |
* | |
* We can then bind to the `tooltip' property as either an expression (`someExpression`) or as a | |
* string literal, as shown in the HTML template below: | |
* | |
* ```html | |
* <div [tooltip]="someExpression">...</div> | |
* <div tooltip="Some Text">...</div> | |
* ``` | |
* | |
* Whenever the `someExpression` expression changes, the `properties` declaration instructs | |
* Angular to update the `Tooltip`'s `text` property. | |
* | |
* ## Bindings With Pipes | |
* | |
* You can also use pipes when writing binding definitions for a directive. | |
* | |
* For example, we could write a binding that updates the directive on structural changes, rather | |
* than on reference changes, as normally occurs in change detection. | |
* | |
* See <a href='/angular2/angular2/Pipe'><code>Pipe</code></a> and <a href='pipes/keyValDiff'>keyValDiff</a> documentation for more details. | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[class-set]', | |
* properties: [ | |
* 'classChanges: classSet | keyValDiff' | |
* ] | |
* }) | |
* class ClassSet { | |
* set classChanges(changes: KeyValueChanges) { | |
* // This will get called every time the `class-set` expressions changes its structure. | |
* } | |
* } | |
* ``` | |
* | |
* The template that this directive is used in may also contain its own pipes. For example: | |
* | |
* ```html | |
* <div [class-set]="someExpression | somePipe"> | |
* ``` | |
* | |
* In this case, the two pipes compose as if they were inlined: `someExpression | somePipe | | |
* keyValDiff`. | |

/** | |
* The CSS selector that triggers the instantiation of a directive. | |
* | |
* Angular only allows directives to trigger on CSS selectors that do not cross element | |
* boundaries. | |
* | |
* `selector` may be declared as one of the following: | |
* | |
* - `element-name`: select by element name. | |
* - `.class`: select by class name. | |
* - `[attribute]`: select by attribute name. | |
* - `[attribute=value]`: select by attribute name and value. | |
* - `:not(sub_selector)`: select only if the element does not match the `sub_selector`. | |
* - `selector1, selector2`: select if either `selector1` or `selector2` matches. | |
* | |
* | |
* ## Example | |
* | |
* Suppose we have a directive with an `input[type=text]` selector. | |
* | |
* And the following HTML: | |
* | |
* ```html | |
* <form> | |
* <input type="text"> | |
* <input type="radio"> | |
* <form> | |
* ``` | |
* | |
* The directive would only be instantiated on the `<input type="text">` element. | |

/** | |
* Bootstrapping for Angular applications. | |
* | |
* You instantiate an Angular application by explicitly specifying a component to use as the root | |
* component for your | |
* application via the `bootstrap()` method. | |
* | |
* ## Simple Example | |
* | |
* Assuming this `index.html`: | |
* | |
* ```html | |
* <html> | |
* <!-- load Angular script tags here. --> | |
* <body> | |
* <my-app>loading...</my-app> | |
* </body> | |
* </html> | |
* ``` | |
* | |
* An application is bootstrapped inside an existing browser DOM, typically `index.html`. Unlike | |
* Angular 1, Angular 2 | |
* does not compile/process bindings in `index.html`. This is mainly for security reasons, as well | |
* as architectural | |
* changes in Angular 2. This means that `index.html` can safely be processed using server-side | |
* technologies such as | |
* bindings. Bindings can thus use double-curly `{{ syntax }}` without collision from Angular 2 | |
* component double-curly | |
* `{{ syntax }}`. | |
* | |
* We can use this script code: | |
* | |
* ``` | |
* @Component({ | |
* selector: 'my-app' | |
* }) | |
* @View({ | |
* template: 'Hello {{ name }}!' | |
* }) | |
* class MyApp { | |
* name:string; | |
* | |
* constructor() { | |
* this.name = 'World'; | |
* } | |
* } | |
* | |
* main() { | |
* return bootstrap(MyApp); | |
* } | |
* ``` | |
* | |
* When the app developer invokes `bootstrap()` with the root component `MyApp` as its argument, | |
* Angular performs the | |
* following tasks: | |
* | |
* 1. It uses the component's `selector` property to locate the DOM element which needs to be | |
* upgraded into | |
* the angular component. | |
* 2. It creates a new child injector (from the platform injector) and configures the injector with | |
* the component's | |
* `appInjector`. Optionally, you can also override the injector configuration for an app by | |
* invoking | |
* `bootstrap` with the `componentInjectableBindings` argument. | |
* 3. It creates a new `Zone` and connects it to the angular application's change detection domain | |
* instance. | |
* 4. It creates a shadow DOM on the selected component's host element and loads the template into | |
* it. | |
* 5. It instantiates the specified component. | |
* 6. Finally, Angular performs change detection to apply the initial data bindings for the | |
* application. | |
* | |
* | |
* ## Instantiating Multiple Applications on a Single Page | |
* | |
* There are two ways to do this. | |
* | |
* | |
* ### Isolated Applications | |
* | |
* Angular creates a new application each time that the `bootstrap()` method is invoked. When | |
* multiple applications | |
* are created for a page, Angular treats each application as independent within an isolated change | |
* detection and | |
* `Zone` domain. If you need to share data between applications, use the strategy described in the | |
* next | |
* section, "Applications That Share Change Detection." | |
* | |
* | |
* ### Applications That Share Change Detection | |
* | |
* If you need to bootstrap multiple applications that share common data, the applications must | |
* share a common | |
* change detection and zone. To do that, create a meta-component that lists the application | |
* components in its template. | |
* By only invoking the `bootstrap()` method once, with the meta-component as its argument, you | |
* ensure that only a | |
* single change detection zone is created and therefore data can be shared across the applications. | |
* | |
* | |
* ## Platform Injector | |
* | |
* When working within a browser window, there are many singleton resources: cookies, title, | |
* location, and others. | |
* Angular services that represent these resources must likewise be shared across all Angular | |
* applications that | |
* occupy the same browser window. For this reason, Angular creates exactly one global platform | |
* injector which stores | |
* all shared services, and each angular application injector has the platform injector as its | |
* parent. | |
* | |
* Each application has its own private injector as well. When there are multiple applications on a | |
* page, Angular treats | |
* each application injector's services as private to that application. | |
* | |
* | |
* # API | |
* - `appComponentType`: The root component which should act as the application. This is a reference | |
* to a `Type` | |
* which is annotated with `@Component(...)`. | |
* - `componentInjectableBindings`: An additional set of bindings that can be added to `appInjector` | |
* for the | |
* <a href='/angular2/angular2/Component'><code>Component</code></a> to override default injection behavior. | |
* - `errorReporter`: `function(exception:any, stackTrace:string)` a default error reporter for | |
* unhandled exceptions. | |
* | |
* Returns a `Promise` with the application`s private <a href='/angular2/angular2/Injector'><code>Injector</code></a>. | |

* <tabs> | |
* <pane title="Overview">...</pane> | |
* <pane *ng-for="#o of objects" [title]="o.title">{{o.text}}</pane> | |
* </tabs> | |
* ``` | |
* | |
* In the above example the list of `<tabs>` elements needs to get a list of `<pane>` elements so | |
* that it could render | |
* tabs with the correct titles and in the correct order. | |
* | |
* A possible solution would be for a `<pane>` to inject `<tabs>` component and then register itself | |
* with `<tabs>` | |
* component's on `hydrate` and deregister on `dehydrate` event. While a reasonable approach, this | |
* would only work | |
* partialy since `*ng-for` could rearange the list of `<pane>` components which would not be | |
* reported to `<tabs>` | |
* component and thus the list of `<pane>` componets would be out of sync with respect to the list | |
* of `<pane>` elements. | |
* | |
* A preferred solution is to inject a `QueryList` which is a live list of directives in the | |

* | |
* ```javascript | |

* binds to. | |
* | |
* When a component is instantiated, Angular | |

* - creates a child <a href='/angular2/angular2/Injector'><code>Injector</code></a> which is configured with the `appInjector` for the | |

* Dynamically loading a component at runtime: | |
* | |
* Regular Angular components are statically resolved. Dynamic components allows to resolve a | |
* component at runtime | |
* instead by providing a placeholder into which a regular Angular component can be dynamically | |
* loaded. Once loaded, | |
* the dynamically-loaded component becomes permanent and cannot be changed. | |
* Dynamic components are declared just like components, but without a `@View` annotation. | |
* | |
* | |
* ## Example | |
* | |
* Here we have `DynamicComp` which acts as the placeholder for `HelloCmp`. At runtime, the dynamic | |
* component | |
* `DynamicComp` requests loading of the `HelloCmp` component. | |
* | |
* There is nothing special about `HelloCmp`, which is a regular Angular component. It can also be | |

/** | |
* Directives allow you to attach behavior to elements in the DOM. | |
* | |
* <a href='/angular2/annotations/Directive'><code>Directive</code></a>s with an embedded view are called <a href='/angular2/angular2/Component'><code>Component</code></a>s. | |
* | |
* A directive consists of a single directive annotation and a controller class. When the | |
* directive's `selector` matches | |
* elements in the DOM, the following steps occur: | |
* | |
* 1. For each directive, the `ElementInjector` attempts to resolve the directive's constructor | |
* arguments. | |
* 2. Angular instantiates directives for each matched element using `ElementInjector` in a | |
* depth-first order, | |
* as declared in the HTML. | |
* | |
* ## Understanding How Injection Works | |
* | |
* There are three stages of injection resolution. | |
* - *Pre-existing Injectors*: | |
* - The terminal <a href='/angular2/angular2/Injector'><code>Injector</code></a> cannot resolve dependencies. It either throws an error or, if | |
* the dependency was | |
* specified as `@Optional`, returns `null`. | |
* - The platform injector resolves browser singleton resources, such as: cookies, title, | |
* location, and others. | |
* - *Component Injectors*: Each component instance has its own <a href='/angular2/angular2/Injector'><code>Injector</code></a>, and they follow | |
* the same parent-child hierarchy | |
* as the component instances in the DOM. | |
* - *Element Injectors*: Each component instance has a Shadow DOM. Within the Shadow DOM each | |
* element has an `ElementInjector` | |
* which follow the same parent-child hierarchy as the DOM elements themselves. | |
* | |
* When a template is instantiated, it also must instantiate the corresponding directives in a | |
* depth-first order. The | |
* current `ElementInjector` resolves the constructor dependencies for each directive. | |
* | |
* Angular then resolves dependencies as follows, according to the order in which they appear in the | |
* <a href='/angular2/angular2/View'><code>View</code></a>: | |
* | |
* 1. Dependencies on the current element | |
* 2. Dependencies on element injectors and their parents until it encounters a Shadow DOM boundary | |
* 3. Dependencies on component injectors and their parents until it encounters the root component | |
* 4. Dependencies on pre-existing injectors | |
* | |
* | |
* The `ElementInjector` can inject other directives, element-specific special objects, or it can | |
* delegate to the parent | |
* injector. | |
* | |
* To inject other directives, declare the constructor parameter as: | |
* - `directive:DirectiveType`: a directive on the current element only | |
* - `@Ancestor() directive:DirectiveType`: any directive that matches the type between the current | |
* element and the | |
* Shadow DOM root. Current element is not included in the resolution, therefore even if it could | |
* resolve it, it will | |
* be ignored. | |
* - `@Parent() directive:DirectiveType`: any directive that matches the type on a direct parent | |
* element only. | |
* - `@Query(DirectiveType) query:QueryList<DirectiveType>`: A live collection of direct child | |
* directives. | |
* - `@QueryDescendants(DirectiveType) query:QueryList<DirectiveType>`: A live collection of any | |
* child directives. | |
* | |
* To inject element-specific special objects, declare the constructor parameter as: | |
* - `element: ElementRef` to obtain a reference to logical element in the view. | |
* - `viewContainer: ViewContainerRef` to control child template instantiation, for | |
* <a href='/angular2/annotations/Directive'><code>Directive</code></a> directives only | |
* - `bindingPropagation: BindingPropagation` to control change detection in a more granular way. | |
* | |
* ## Example | |
* | |
* The following example demonstrates how dependency injection resolves constructor arguments in | |
* practice. | |
* | |
* | |
* Assume this HTML template: | |
* | |
* ``` | |
* <div dependency="1"> | |
* <div dependency="2"> | |
* <div dependency="3" my-directive> | |
* <div dependency="4"> | |
* <div dependency="5"></div> | |
* </div> | |
* <div dependency="6"></div> | |
* </div> | |
* </div> | |
* </div> | |
* ``` | |
* | |
* With the following `dependency` decorator and `SomeService` injectable class. | |
* | |
* ``` | |
* @Injectable() | |
* class SomeService { | |
* } | |
* | |
* @Directive({ | |
* selector: '[dependency]', | |
* properties: [ | |
* 'id: dependency' | |
* ] | |
* }) | |
* class Dependency { | |
* id:string; | |
* } | |
* ``` | |
* | |
* Let's step through the different ways in which `MyDirective` could be declared... | |
* | |
* | |
* ### No injection | |
* | |
* Here the constructor is declared with no arguments, therefore nothing is injected into | |
* `MyDirective`. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor() { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with no dependencies. | |
* | |
* | |
* ### Component-level injection | |
* | |
* Directives can inject any injectable instance from the closest component injector or any of its | |
* parents. | |
* | |
* Here, the constructor declares a parameter, `someService`, and injects the `SomeService` type | |
* from the parent | |
* component's injector. | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(someService: SomeService) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a dependency on `SomeService`. | |
* | |
* | |
* ### Injecting a directive from the current element | |
* | |
* Directives can inject other directives declared on the current element. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(dependency: Dependency) { | |
* expect(dependency.id).toEqual(3); | |
* } | |
* } | |
* ``` | |
* This directive would be instantiated with `Dependency` declared at the same element, in this case | |
* `dependency="3"`. | |
* | |
* | |
* ### Injecting a directive from a direct parent element | |
* | |
* Directives can inject other directives declared on a direct parent element. By definition, a | |
* directive with a | |
* `@Parent` annotation does not attempt to resolve dependencies for the current element, even if | |
* this would satisfy | |
* the dependency. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Parent() dependency: Dependency) { | |
* expect(dependency.id).toEqual(2); | |
* } | |
* } | |
* ``` | |
* This directive would be instantiated with `Dependency` declared at the parent element, in this | |
* case `dependency="2"`. | |
* | |
* | |
* ### Injecting a directive from any ancestor elements | |
* | |
* Directives can inject other directives declared on any ancestor element (in the current Shadow | |
* DOM), i.e. on the | |
* parent element and its parents. By definition, a directive with an `@Ancestor` annotation does | |
* not attempt to | |
* resolve dependencies for the current element, even if this would satisfy the dependency. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Ancestor() dependency: Dependency) { | |
* expect(dependency.id).toEqual(2); | |
* } | |
* } | |
* ``` | |
* | |
* Unlike the `@Parent` which only checks the parent, `@Ancestor` checks the parent, as well as its | |
* parents recursively. If `dependency="2"` didn't exist on the direct parent, this injection would | |
* have returned | |
* `dependency="1"`. | |
* | |
* | |
* ### Injecting a live collection of direct child directives | |
* | |
* | |
* A directive can also query for other child directives. Since parent directives are instantiated | |
* before child directives, a directive can't simply inject the list of child directives. Instead, | |
* the directive injects a <a href='QueryList'>QueryList</a>, which updates its contents as children are added, | |
* removed, or moved by a directive that uses a <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> such as a `ng-for`, an | |
* `ng-if`, or an `ng-switch`. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Query(Dependency) dependencies:QueryList<Dependency>) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a <a href='QueryList'>QueryList</a> which contains `Dependency` 4 and | |
* 6. Here, `Dependency` 5 would not be included, because it is not a direct child. | |
* | |
* ### Injecting a live collection of descendant directives | |
* | |
* Note: This is will be implemented in later release. () | |
* | |
* Similar to `@Query` above, but also includes the children of the child elements. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@QueryDescendents(Dependency) dependencies:QueryList<Dependency>) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a Query which would contain `Dependency` 4, 5 and 6. | |
* | |
* ### Optional injection | |
* | |
* The normal behavior of directives is to return an error when a specified dependency cannot be | |
* resolved. If you | |
* would like to inject `null` on unresolved dependency instead, you can annotate that dependency | |
* with `@Optional()`. | |
* This explicitly permits the author of a template to treat some of the surrounding directives as | |
* optional. | |
* | |
* ``` | |
* @Directive({ selector: '[my-directive]' }) | |
* class MyDirective { | |
* constructor(@Optional() dependency:Dependency) { | |
* } | |
* } | |
* ``` | |
* | |
* This directive would be instantiated with a `Dependency` directive found on the current element. | |
* If none can be | |
* found, the injector supplies `null` instead of throwing an error. | |
* | |
* ## Example | |
* | |
* Here we use a decorator directive to simply define basic tool-tip behavior. | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[tooltip]', | |
* properties: [ | |
* 'text: tooltip' | |
* ], | |
* hostListeners: { | |
* 'onmouseenter': 'onMouseEnter()', | |
* 'onmouseleave': 'onMouseLeave()' | |
* } | |
* }) | |
* class Tooltip{ | |
* text:string; | |
* overlay:Overlay; // NOT YET IMPLEMENTED | |
* overlayManager:OverlayManager; // NOT YET IMPLEMENTED | |
* | |
* constructor(overlayManager:OverlayManager) { | |
* this.overlay = overlay; | |
* } | |
* | |
* onMouseEnter() { | |
* // exact signature to be determined | |
* this.overlay = this.overlayManager.open(text, ...); | |
* } | |
* | |
* onMouseLeave() { | |
* this.overlay.close(); | |
* this.overlay = null; | |
* } | |
* } | |
* ``` | |
* In our HTML template, we can then add this behavior to a `<div>` or any other element with the | |
* `tooltip` selector, | |
* like so: | |
* | |
* ``` | |
* <div tooltip="some text here"></div> | |
* ``` | |
* | |
* Directives can also control the instantiation, destruction, and positioning of inline template | |
* elements: | |
* | |
* A directive uses a <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> to instantiate, insert, move, and destroy views at | |
* runtime. | |
* The <a href='/angular2/angular2/ViewContainerRef'><code>ViewContainerRef</code></a> is created as a result of `<template>` element, and represents a | |
* location in the current view | |
* where these actions are performed. | |
* | |
* Views are always created as children of the current <a href='/angular2/angular2/View'><code>View</code></a>, and as siblings of the | |
* `<template>` element. Thus a | |
* directive in a child view cannot inject the directive that created it. | |
* | |
* Since directives that create views via ViewContainers are common in Angular, and using the full | |
* `<template>` element syntax is wordy, Angular | |
* also supports a shorthand notation: `<li *foo="bar">` and `<li template="foo: bar">` are | |
* equivalent. | |
* | |
* Thus, | |
* | |
* ``` | |
* <ul> | |
* <li *foo="bar" title="text"></li> | |
* </ul> | |
* ``` | |
* | |
* Expands in use to: | |
* | |
* ``` | |
* <ul> | |
* <template [foo]="bar"> | |
* <li title="text"></li> | |
* </template> | |
* </ul> | |
* ``` | |
* | |
* Notice that although the shorthand places `*foo="bar"` within the `<li>` element, the binding for | |
* the directive | |
* controller is correctly instantiated on the `<template>` element rather than the `<li>` element. | |
* | |
* | |
* ## Example | |
* | |
* Let's suppose we want to implement the `unless` behavior, to conditionally include a template. | |
* | |
* Here is a simple directive that triggers on an `unless` selector: | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[unless]', | |
* properties: ['unless'] | |
* }) | |
* export class Unless { | |
* viewContainer: ViewContainerRef; | |
* protoViewRef: ProtoViewRef; | |
* prevCondition: boolean; | |
* | |
* constructor(viewContainer: ViewContainerRef, protoViewRef: ProtoViewRef) { | |
* this.viewContainer = viewContainer; | |
* this.protoViewRef = protoViewRef; | |
* this.prevCondition = null; | |
* } | |
* | |
* set unless(newCondition) { | |
* if (newCondition && (isBlank(this.prevCondition) || !this.prevCondition)) { | |
* this.prevCondition = true; | |
* this.viewContainer.clear(); | |
* } else if (!newCondition && (isBlank(this.prevCondition) || this.prevCondition)) { | |
* this.prevCondition = false; | |
* this.viewContainer.create(this.protoViewRef); | |
* } | |
* } | |
* } | |
* ``` | |
* | |
* We can then use this `unless` selector in a template: | |
* ``` | |
* <ul> | |
* <li *unless="expr"></li> | |
* </ul> | |
* ``` | |
* | |
* Once the directive instantiates the child view, the shorthand notation for the template expands | |
* and the result is: | |
* | |
* ``` | |
* <ul> | |
* <template [unless]="exp"> | |
* <li></li> | |
* </template> | |
* <li></li> | |
* </ul> | |
* ``` | |
* | |
* Note also that although the `<li></li>` template still exists inside the `<template></template>`, | |
* the instantiated | |
* view occurs on the second `<li></li>` which is a sibling to the `<template>` element. | |

* - `statement`: the statement to execute when the event occurs. | |
* If the evalutation of the statement returns `false`, then `preventDefault`is applied on the DOM | |
* event. | |
* | |
* To listen to global events, a target must be added to the event name. | |
* The target can be `window`, `document` or `body`. | |
* | |
* When writing a directive event binding, you can also refer to the following local variables: | |
* - `$event`: Current event object which triggered the event. | |
* - `$target`: The source of the event. This will be either a DOM element or an Angular | |

* ## Basic Event Binding: | |

* | |
* ``` | |
* @Directive({ | |

* hostListeners: { | |
* 'change': 'onChange($event)', | |
* 'window:resize': 'onResize($event)' | |

* onChange(event:Event) { | |
* } | |
* onResize(event:Event) { | |

/** | |
* Enumerates the set of properties that accept data binding for a directive. | |
* | |
* The `properties` property defines a set of `directiveProperty` to `bindingProperty` | |
* configuration: | |
* | |
* - `directiveProperty` specifies the component property where the value is written. | |
* - `bindingProperty` specifies the DOM property where the value is read from. | |
* | |
* You can include a <a href='/angular2/angular2/Pipe'><code>Pipe</code></a> when specifying a `bindingProperty` to allow for data | |
* transformation and structural change detection of the value. These pipes will be evaluated in | |
* the context of this component. | |
* | |
* ## Syntax | |
* | |
* There is no need to specify both `directiveProperty` and `bindingProperty` when they both have | |
* the same value. | |
* | |
* ``` | |
* @Directive({ | |
* properties: [ | |
* 'propertyName', // shorthand notation for 'propertyName: propertyName' | |
* 'directiveProperty1: bindingProperty1', | |
* 'directiveProperty2: bindingProperty2 | pipe1 | ...', | |
* ... | |
* ] | |
* } | |
* ``` | |
* | |
* | |
* ## Basic Property Binding | |
* | |
* We can easily build a simple `Tooltip` directive that exposes a `tooltip` property, which can | |
* be used in templates with standard Angular syntax. For example: | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[tooltip]', | |
* properties: [ | |
* 'text: tooltip' | |
* ] | |
* }) | |
* class Tooltip { | |
* set text(value: string) { | |
* // This will get called every time with the new value when the 'tooltip' property changes | |
* } | |
* } | |
* ``` | |
* | |
* We can then bind to the `tooltip' property as either an expression (`someExpression`) or as a | |
* string literal, as shown in the HTML template below: | |
* | |
* ```html | |
* <div [tooltip]="someExpression">...</div> | |
* <div tooltip="Some Text">...</div> | |
* ``` | |
* | |
* Whenever the `someExpression` expression changes, the `properties` declaration instructs | |
* Angular to update the `Tooltip`'s `text` property. | |
* | |
* ## Bindings With Pipes | |
* | |
* You can also use pipes when writing binding definitions for a directive. | |
* | |
* For example, we could write a binding that updates the directive on structural changes, rather | |
* than on reference changes, as normally occurs in change detection. | |
* | |
* See <a href='/angular2/angular2/Pipe'><code>Pipe</code></a> and <a href='pipes/keyValDiff'>keyValDiff</a> documentation for more details. | |
* | |
* ``` | |
* @Directive({ | |
* selector: '[class-set]', | |
* properties: [ | |
* 'classChanges: classSet | keyValDiff' | |
* ] | |
* }) | |
* class ClassSet { | |
* set classChanges(changes: KeyValueChanges) { | |
* // This will get called every time the `class-set` expressions changes its structure. | |
* } | |
* } | |
* ``` | |
* | |
* The template that this directive is used in may also contain its own pipes. For example: | |
* | |
* ```html | |
* <div [class-set]="someExpression | somePipe"> | |
* ``` | |
* | |
* In this case, the two pipes compose as if they were inlined: `someExpression | somePipe | | |
* keyValDiff`. | |
