/**
|
|
* @description
|
|
*
|
|
* A service that applications can use to interact with a browser's URL.
|
|
*
|
|
* Depending on the `LocationStrategy` used, `Location` persists
|
|
* to the URL's path or the URL's hash segment.
|
|
*
|
|
* @usageNotes
|
|
*
|
|
* It's better to use the `Router.navigate()` service to trigger route changes. Use
|
|
* `Location` only if you need to interact with or create normalized URLs outside of
|
|
* routing.
|
|
*
|
|
* `Location` is responsible for normalizing the URL against the application's base href.
|
|
* A normalized URL is absolute from the URL host, includes the application's base href, and has no
|
|
* trailing slash:
|
|
* - `/my/app/user/123` is normalized
|
|
* - `my/app/user/123` **is not** normalized
|
|
* - `/my/app/user/123/` **is not** normalized
|
|
*
|
|
* ### Example
|
|
*
|
|
* <code-example path='common/location/ts/path_location_component.ts'
|
|
* region='LocationComponent'></code-example>

/**
|
|
* A [structural directive](guide/structural-directives) that renders
|
|
* a template for each item in a collection.
|
|
* The directive is placed on an element, which becomes the parent
|
|
* of the cloned templates.
|
|
*
|
|
* The `ngForOf` directive is generally used in the
|
|
* [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
|
|
* In this form, the template to be rendered for each iteration is the content
|
|
* of an anchor element containing the directive.
|
|
*
|
|
* The following example shows the shorthand syntax with some options,
|
|
* contained in an `<li>` element.
|
|
*
|
|
* ```
|
|
* <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
|
|
* ```
|
|
*
|
|
* The shorthand form expands into a long form that uses the `ngForOf` selector
|
|
* on an `<ng-template>` element.
|
|
* The content of the `<ng-template>` element is the `<li>` element that held the
|
|
* short-form directive.
|
|
*
|
|
* Here is the expanded version of the short-form example.
|
|
*
|
|
* ```
|
|
* <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
|
|
* <li>...</li>
|
|
* </ng-template>
|
|
* ```
|
|
*
|
|
* Angular automatically expands the shorthand syntax as it compiles the template.
|
|
* The context for each embedded view is logically merged to the current component
|
|
* context according to its lexical position.
|
|
*
|
|
* When using the shorthand syntax, Angular allows only [one structural directive
|
|
* on an element](guide/built-in-directives#one-per-element).
|
|
* If you want to iterate conditionally, for example,
|
|
* put the `*ngIf` on a container element that wraps the `*ngFor` element.
|
|
* For futher discussion, see
|
|
* [Structural Directives](guide/built-in-directives#one-per-element).
|
|
*
|
|
* @usageNotes
|
|
*
|
|
* ### Local variables
|
|
*
|
|
* `NgForOf` provides exported values that can be aliased to local variables.
|
|
* For example:
|
|
*
|
|
* ```
|
|
* <li *ngFor="let user of users; index as i; first as isFirst">
|
|
* {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
|
|
* </li>
|
|
* ```
|
|
*
|
|
* The following exported values can be aliased to local variables:
|
|
*
|
|
* - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
|
|
* - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
|
|
* more complex then a property access, for example when using the async pipe (`userStreams |
|
|
* async`).
|
|
* - `index: number`: The index of the current item in the iterable.
|
|
* - `count: number`: The length of the iterable.
|
|
* - `first: boolean`: True when the item is the first item in the iterable.
|
|
* - `last: boolean`: True when the item is the last item in the iterable.
|
|
* - `even: boolean`: True when the item has an even index in the iterable.
|
|
* - `odd: boolean`: True when the item has an odd index in the iterable.
|
|
*
|
|
* ### Change propagation
|
|
*
|
|
* When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
|
|
*
|
|
* * When an item is added, a new instance of the template is added to the DOM.
|
|
* * When an item is removed, its template instance is removed from the DOM.
|
|
* * When items are reordered, their respective templates are reordered in the DOM.
|
|
*
|
|
* Angular uses object identity to track insertions and deletions within the iterator and reproduce
|
|
* those changes in the DOM. This has important implications for animations and any stateful
|
|
* controls that are present, such as `<input>` elements that accept user input. Inserted rows can
|
|
* be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
|
|
* such as user input.
|
|
* For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
|
|
*
|
|
* The identities of elements in the iterator can change while the data does not.
|
|
* This can happen, for example, if the iterator is produced from an RPC to the server, and that
|
|
* RPC is re-run. Even if the data hasn't changed, the second response produces objects with
|
|
* different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
|
|
* elements were deleted and all new elements inserted).
|
|
*
|
|
* To avoid this expensive operation, you can customize the default tracking algorithm.
|
|
* by supplying the `trackBy` option to `NgForOf`.
|
|
* `trackBy` takes a function that has two arguments: `index` and `item`.
|
|
* If `trackBy` is given, Angular tracks changes by the return value of the function.

|
|
* ```
|
|
*
|
|
* @usageNotes
|
|
*
|
|
* The `*ngIf` directive is most commonly used to conditionally show an inline template,
|
|
* as seen in the following example.
|
|
* The default `else` template is blank.
|
|
*
|
|
* {@example common/ngIf/ts/module.ts region='NgIfSimple'}
|
|
*
|
|
* ### Showing an alternative template using `else`
|
|
*
|
|
* To display a template when `expression` evaluates to false, use an `else` template
|
|
* binding as shown in the following example.
|
|
* The `else` binding points to an `<ng-template>` element labeled `#elseBlock`.
|
|
* The template can be defined anywhere in the component view, but is typically placed right after
|
|
* `ngIf` for readability.
|
|
*
|
|
* {@example common/ngIf/ts/module.ts region='NgIfElse'}
|
|
*
|
|
* ### Using an external `then` template
|
|
*
|
|
* In the previous example, the then-clause template is specified inline, as the content of the
|
|
* tag that contains the `ngIf` directive. You can also specify a template that is defined
|
|
* externally, by referencing a labeled `<ng-template>` element. When you do this, you can
|
|
* change which template to use at runtime, as shown in the following example.
|
|
*
|
|
* {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
|
|
*
|
|
* ### Storing a conditional result in a variable
|
|
*
|
|
* You might want to show a set of properties from the same object. If you are waiting
|
|
* for asynchronous data, the object can be undefined.
|
|
* In this case, you can use `ngIf` and store the result of the condition in a local
|
|
* variable as shown in the following example.
|
|
*
|
|
* {@example common/ngIf/ts/module.ts region='NgIfAs'}
|
|
*
|
|
* This code uses only one `AsyncPipe`, so only one subscription is created.
|
|
* The conditional statement stores the result of `userStream|async` in the local variable `user`.
|
|
* You can then bind the local `user` repeatedly.
|
|
*
|
|
* The conditional displays the data only if `userStream` returns a value,
|
|
* so you don't need to use the
|
|
* safe-navigation-operator (`?.`)
|
|
* to guard against null values when accessing properties.
|
|
* You can display an alternative template while waiting for the data.
|
|
*
|
|
* ### Shorthand syntax
|
|
*
|
|
* The shorthand syntax `*ngIf` expands into two separate template specifications
|
|
* for the "then" and "else" clauses. For example, consider the following shorthand statement,
|
|
* that is meant to show a loading page while waiting for data to be loaded.
|
|
*
|
|
* ```
|
|
* <div class="hero-list" *ngIf="heroes else loading">
|
|
* ...
|
|
* </div>
|
|
*
|
|
* <ng-template #loading>
|
|
* <div>Loading...</div>
|
|
* </ng-template>
|
|
* ```
|
|
*
|
|
* You can see that the "else" clause references the `<ng-template>`
|
|
* with the `#loading` label, and the template for the "then" clause
|
|
* is provided as the content of the anchor element.
|
|
*
|
|
* However, when Angular expands the shorthand syntax, it creates
|
|
* another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
|
|
* The anchor element containing the template for the "then" clause becomes
|
|
* the content of this unlabeled `<ng-template>` tag.
|
|
*
|
|
* ```
|
|
* <ng-template [ngIf]="heroes" [ngIfElse]="loading">
|
|
* <div class="hero-list">
|
|
* ...
|
|
* </div>
|
|
* </ng-template>
|
|
*
|
|
* <ng-template #loading>
|
|
* <div>Loading...</div>
|
|
* </ng-template>
|
|
* ```
|
|
*
|
|
* The presence of the implicit template object has implications for the nesting of
|
|
* structural directives. For more on this subject, see

/**
|

* @ngModule CommonModule
|
|
*
|
|
* @description
|
|
* The `[ngSwitch]` directive on a container specifies an expression to match against.
|
|
* The expressions to match are provided by `ngSwitchCase` directives on views within the container.
|
|
* - Every view that matches is rendered.
|
|
* - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
|
|
* - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
|
|
* or `ngSwitchDefault` directive are preserved at the location.
|
|
*
|
|
* @usageNotes
|
|
* Define a container element for the directive, and specify the switch expression
|
|
* to match against as an attribute:
|
|
*
|
|
* ```
|
|
* <container-element [ngSwitch]="switch_expression">
|
|
* ```
|
|
*
|
|
* Within the container, `*ngSwitchCase` statements specify the match expressions
|
|
* as attributes. Include `*ngSwitchDefault` as the final case.
|
|
*
|
|
* ```
|
|
* <container-element [ngSwitch]="switch_expression">
|
|
* <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|
* ...
|
|
* <some-element *ngSwitchDefault>...</some-element>
|
|
* </container-element>
|
|
* ```
|
|
*
|
|
* ### Usage Examples
|
|
*
|
|
* The following example shows how to use more than one case to display the same view:
|
|
*
|
|
* ```
|
|
* <container-element [ngSwitch]="switch_expression">
|
|
* <!-- the same view can be shown in more than one case -->
|
|
* <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|
* <some-element *ngSwitchCase="match_expression_2">...</some-element>
|
|
* <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
|
|
* <!--default case when there are no matches -->
|
|
* <some-element *ngSwitchDefault>...</some-element>
|
|
* </container-element>
|
|
* ```
|
|
*
|
|
* The following example shows how cases can be nested:
|
|
* ```
|
|
* <container-element [ngSwitch]="switch_expression">
|
|
* <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|
* <some-element *ngSwitchCase="match_expression_2">...</some-element>
|
|
* <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
|
|
* <ng-container *ngSwitchCase="match_expression_3">
|
|
* <!-- use a ng-container to group multiple root nodes -->
|
|
* <inner-element></inner-element>
|
|
* <inner-other-element></inner-other-element>
|
|
* </ng-container>
|
|
* <some-element *ngSwitchDefault>...</some-element>
|
|
* </container-element>

|
|
* Unwraps a value from an asynchronous primitive.
|
|
*
|
|
* The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has
|
|
* emitted. When a new value is emitted, the `async` pipe marks the component to be checked for
|
|
* changes. When the component gets destroyed, the `async` pipe unsubscribes automatically to avoid
|
|
* potential memory leaks. When the reference of the expression changes, the `async` pipe
|
|
* automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.
|
|
*
|
|
* @usageNotes
|
|
*
|
|
* ### Examples
|
|
*
|
|
* This example binds a `Promise` to the view. Clicking the `Resolve` button resolves the
|
|
* promise.
|
|
*
|
|
* {@example common/pipes/ts/async_pipe.ts region='AsyncPipePromise'}
|
|
*
|
|
* It's also possible to use `async` with Observables. The example below binds the `time` Observable
|
|
* to the view. The Observable continuously updates the view with the current time.
|

*
|
|
* {@example common/pipes/ts/async_pipe.ts region='AsyncPipeObservable'}

* @description
|
|
*
|
|
* Formats a date value according to locale rules.
|
|
*
|
|
* `DatePipe` is executed only when it detects a pure change to the input value.
|
|
* A pure change is either a change to a primitive input value
|
|
* (such as `String`, `Number`, `Boolean`, or `Symbol`),
|
|
* or a changed object reference (such as `Date`, `Array`, `Function`, or `Object`).
|
|
*
|
|
* Note that mutating a `Date` object does not cause the pipe to be rendered again.
|
|
* To ensure that the pipe is executed, you must create a new `Date` object.
|
|
*
|
|
* Only the `en-US` locale data comes with Angular. To localize dates
|
|
* in another language, you must import the corresponding locale data.
|
|
* See the [I18n guide](guide/i18n-common-format-data-locale) for more information.
|
|
*
|
|
* @see `formatDate()`
|
|
*
|
|
*
|
|
* @usageNotes
|
|
*
|
|
* The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
|
|
* reformat the date on every change-detection cycle, treat the date as an immutable object
|
|
* and change the reference when the pipe needs to run again.
|
|
*
|
|

|
|
* Format details depend on the locale.
|
|
* Fields marked with (*) are only available in the extra data set for the given locale.

|
|
* ### Format examples
|
|
*
|
|
* These examples transform a date into various formats,
|
|
* assuming that `dateObj` is a JavaScript `Date` object for
|
|
* year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
|
|
* given in the local time for the `en-US` locale.
|
|
*
|
|
* ```
|
|
* {{ dateObj | date }} // output is 'Jun 15, 2015'
|
|
* {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'
|
|
* {{ dateObj | date:'shortTime' }} // output is '9:43 PM'
|
|
* {{ dateObj | date:'mm:ss' }} // output is '43:11'
|
|
* ```
|
|
*
|
|
* ### Usage example
|
|
*
|
|
* The following component uses a date pipe to display the current date in different formats.
|
|
*
|
|
* ```
|
|
* @Component({
|
|
* selector: 'date-pipe',
|
|
* template: `<div>
|
|
* <p>Today is {{today | date}}</p>
|
|
* <p>Or if you prefer, {{today | date:'fullDate'}}</p>
|
|
* <p>The time is {{today | date:'h:mm a z'}}</p>
|
|
* </div>`
|
|
* })
|
|
* // Get the current date and time as a date-time value.
|
|
* export class DatePipeComponent {
|
|
* today: number = Date.now();
|
|
* }
|
|
* ```
|
|
*

|
* ```
|
