|
||
The NgClass directive uses the custom change detection algorithm for its inputs. The custom
|
||
algorithm is necessary since inputs are represented as complex object or arrays that need to be
|
||
deeply-compared.
|
||
|
||
This algorithm is perf-sensitive since NgClass is used very frequently and its poor performance
|
||
might negatively impact runtime performance of the entire change detection cycle. The design of
|
||
this algorithm is making sure that:
|
||
- there is no unnecessary DOM manipulation (CSS classes are added / removed from the DOM only when
|
||
needed), even if references to bound objects change;
|
||
- there is no memory allocation if nothing changes (even relatively modest memory allocation
|
||
during the change detection cycle can result in GC pauses for some of the CD cycles).
|
||
|
||
The algorithm works by iterating over the set of bound classes, staring with [class] binding and
|
||
then going over [ngClass] binding. For each CSS class name:
|
||
- check if it was seen before (this information is tracked in the state map) and if its value
|
||
changed;
|
||
- mark it as "touched" - names that are not marked are not present in the latest set of binding
|
||
and we can remove such class name from the internal data structures;
|
||
|
||
After iteration over all the CSS class names we've got data structure with all the information
|
||
necessary to synchronize changes to the DOM - it is enough to iterate over the state map, flush
|
||
changes to the DOM and reset internal data structures so those are ready for the next change
|
||
detection cycle.

* ### Fine tune control
|
||
*
|
||
* You can control the component creation process by using the following optional attributes:
|
||
*
|
||
* * `ngComponentOutletInputs`: Optional component inputs object, which will be bind to the
|
||
* component.
|
||
*
|
||
* * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for

|
||
* * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
|
||
* section of the component, if it exists.
|
||
*
|
||
* * `ngComponentOutletNgModule`: Optional NgModule class reference to allow loading another
|
||
* module dynamically, then loading a component from that module.
|
||
*
|
||
* * `ngComponentOutletNgModuleFactory`: Deprecated config option that allows providing optional
|
||
* NgModule factory to allow loading another module dynamically, then loading a component from that
|
||
* module. Use `ngComponentOutletNgModule` instead.
|
||
*
|
||
* ### Syntax
|
||
*
|
||
* Simple
|
||
* ```html
|
||
* <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
|
||
* ```
|
||
*
|
||
* With inputs
|
||
* ```html
|
||
* <ng-container *ngComponentOutlet="componentTypeExpression;
|
||
* inputs: inputsExpression;">
|
||
* </ng-container>
|
||
* ```
|
||
*
|
||
* Customized injector/content
|
||
* ```html
|
||
* <ng-container *ngComponentOutlet="componentTypeExpression;
|
||
* injector: injectorExpression;
|
||
* content: contentNodesExpression;">
|
||
* </ng-container>
|
||
* ```
|
||
*
|
||
* Customized NgModule reference
|
||
* ```html

/**
|
||
* A [structural directive](guide/directives/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/directives/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.
|
||
*
|
||
* ```html
|
||
* <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.
|
||
*
|
||
* ```html
|
||
* <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/directives/structural-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 further discussion, see
|
||
* [Structural Directives](guide/directives/structural-directives#one-per-element).
|
||
*
|
||
* @usageNotes
|
||
*
|
||
* ### Local variables
|
||
*
|
||
* `NgForOf` provides exported values that can be aliased to local variables.
|
||
* For example:
|
||
*
|
||
* ```html
|
||
* <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/animations/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.

||
* ### 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.
|
||
*
|
||
* ```html
|
||
* <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.
|
||
*
|
||
* ```html
|
||
* <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
|
||
* [Structural Directives](guide/directives/structural-directives#one-per-element).

|
||
* 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:
|
||
*
|
||
* ```html
|
||
* <container-element [ngSwitch]="switch_expression">
|
||
* ```
|
||
*
|
||
* Within the container, `*ngSwitchCase` statements specify the match expressions
|
||
* as attributes. Include `*ngSwitchDefault` as the final case.
|
||
*
|
||
* ```html
|
||
* <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:
|
||
*
|
||
* ```html
|
||
* <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:
|
||
* ```html
|
||
* <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>

|

* @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/format-data-locale) for more information.
|
||
*
|
||
* The time zone of the formatted value can be specified either by passing it in as the second
|
||
* parameter of the pipe, or by setting the default through the `DATE_PIPE_DEFAULT_OPTIONS`
|
||
* injection token. The value that is passed in as the second parameter takes precedence over
|
||
* the one defined using the injection token.
|
||
*
|
||
* @see {@link 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.
|
||
*
|
||
* ### Pre-defined format options
|
||
*
|
||
* | Option | Equivalent to | Examples (given in `en-US` locale) |

|
||
*
|
||
* You can construct a format string using symbols to specify the components

|
||
* ### 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'
|
||
* {{ dateObj | date:"MMM dd, yyyy 'at' hh:mm a" }} // output is 'Jun 15, 2015 at 09:43 PM'
|
||
* ```
|
||
*
|
||
* ### Usage example
|
||
*
|
||
* The following component uses a date pipe to display the current date in different formats.
|
||
*
|
||
* ```angular-ts
|
||
* @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();
|
||
* }
|
||
* ```

*
|
||
* @usageNotes
|

*
|
||
* ### digitsInfo
|
||
*
|
||
* The value's decimal representation is specified by the `digitsInfo`
|
||
* parameter, written in the following format:<br>
|
||
*
|
||
* ```
|
||
* {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}
|
||
* ```
|
||
*
|
||
* - `minIntegerDigits`:
|
||
* The minimum number of integer digits before the decimal point.
|
||
* Default is 1.
|
||
*
|
||
* - `minFractionDigits`:
|
||
* The minimum number of digits after the decimal point.
|
||
* Default is 0.
|
||
*
|
||
* - `maxFractionDigits`:
|
||
* The maximum number of digits after the decimal point.
|
||
* Default is 3.
|
||
*
|
||
* If the formatted value is truncated it will be rounded using the "to-nearest" method:
|
||
*
|
||
* ```
|
||
* {{3.6 | number: '1.0-0'}}
|
||
* <!--will output '4'-->
|
||
*
|
||
* {{-3.6 | number:'1.0-0'}}
|
||
* <!--will output '-4'-->
|
||
* ```
|
||
*
|
||
* ### locale
|
||
*
|
||
* `locale` will format a value according to locale rules.
|
||
* Locale determines group sizing and separator,
|
||
* decimal point character, and other locale-specific configurations.
|
||
*
|
||
* When not supplied, uses the value of `LOCALE_ID`, which is `en-US` by default.
