| 63 | * The `async` pipe subscribes to an `Observable` or `Promise` and returns the latest value it has

|
|---|

| 66 | * potential memory leaks. When the reference of the expression changes, the `async` pipe
|

| 67 | * automatically unsubscribes from the old `Observable` or `Promise` and subscribes to the new one.

|

| 72 | *
|

|

| 78 | * It's also possible to use `async` with Observables. The example below binds the `time` Observable
|
|---|
| 79 | * to the view. The Observable continuously updates the view with the current time.

| 292 | * ### Format examples
|
|---|
| 293 | *
|
|---|
| 294 | * These examples transform a date into various formats,
|
|---|
| 295 | * assuming that `dateObj` is a JavaScript `Date` object for
|
|---|
| 296 | * year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11,
|
|---|
| 297 | * given in the local time for the `en-US` locale.
|
|---|
| 298 | *
|
|---|
| 299 | * ```
|
|---|
| 300 | * {{ dateObj | date }} // output is 'Jun 15, 2015'
|
|---|
| 301 | * {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'
|
|---|
| 302 | * {{ dateObj | date:'shortTime' }} // output is '9:43 PM'
|
|---|
| 303 | * {{ dateObj | date:'mm:ss' }} // output is '43:11'
|
|---|
| 304 | * ```
|
|---|
| 305 | *
|
|---|
| 306 | * ### Usage example
|
|---|
| 307 | *
|
|---|
| 308 | * The following component uses a date pipe to display the current date in different formats.
|
|---|
| 309 | *
|
|---|
| 310 | * ```
|
|---|
| 311 | * @Component({
|
|---|
| 312 | * selector: 'date-pipe',
|
|---|
| 313 | * template: `<div>
|
|---|
| 314 | * <p>Today is {{today | date}}</p>
|
|---|
| 315 | * <p>Or if you prefer, {{today | date:'fullDate'}}</p>
|
|---|
| 316 | * <p>The time is {{today | date:'h:mm a z'}}</p>
|
|---|
| 317 | * </div>`
|
|---|
| 318 | * })
|
|---|
| 319 | * // Get the current date and time as a date-time value.
|
|---|
| 320 | * export class DatePipeComponent {
|
|---|
| 321 | * today: number = Date.now();
|
|---|
| 322 | * }
|
|---|
| 323 | * ```

|
|---|
| 363 | *
|
|---|
| 364 | * The value's decimal representation is specified by the `digitsInfo`
|
|---|
| 365 | * parameter, written in the following format:<br>
|
|---|
| 366 | *
|
|---|
| 367 | * ```

|
|---|
| 370 | *
|
|---|
| 371 | * - `minIntegerDigits`:
|
|---|
| 372 | * The minimum number of integer digits before the decimal point.
|
|---|
| 373 | * Default is 1.
|
|---|
| 374 | *
|
|---|
| 375 | * - `minFractionDigits`:
|
|---|
| 376 | * The minimum number of digits after the decimal point.
|
|---|
| 377 | * Default is 0.
|
|---|
| 378 | *
|
|---|
| 379 | * - `maxFractionDigits`:
|
|---|
| 380 | * The maximum number of digits after the decimal point.
|
|---|
| 381 | * Default is 3.
|
|---|
| 382 | *
|
|---|
| 383 | * If the formatted value is truncated it will be rounded using the "to-nearest" method:
|
|---|
| 384 | *
|
|---|
| 385 | * ```
|
|---|
| 386 | * {{3.6 | number: '1.0-0'}}

| 390 | * <!--will output '-4'-->
|
|---|
| 391 | * ```
|
|---|
| 392 | *
|
|---|
| 393 | * ### locale
|
|---|
| 394 | *
|
|---|
| 395 | * `locale` will format a value according to locale rules.
|
|---|
| 396 | * Locale determines group sizing and separator,
|
|---|
| 397 | * decimal point character, and other locale-specific configurations.

|

|---|
| 1389 | *
|
|---|
| 1390 | * * `ngComponentOutletInjector`: Optional custom {@link Injector} that will be used as parent for
|
|---|
| 1391 | * the Component. Defaults to the injector of the current view container.
|
|---|
| 1392 | *
|
|---|
| 1393 | * * `ngComponentOutletContent`: Optional list of projectable nodes to insert into the content
|
|---|
| 1394 | * section of the component, if it exists.
|
|---|
| 1395 | *
|
|---|
| 1396 | * * `ngComponentOutletNgModuleFactory`: Optional module factory to allow loading another
|
|---|
| 1397 | * module dynamically, then loading a component from that module.
|
|---|
| 1398 | *
|
|---|
| 1399 | * ### Syntax
|
|---|
| 1400 | *
|
|---|
| 1401 | * Simple
|
|---|
| 1402 | * ```
|
|---|
| 1403 | * <ng-container *ngComponentOutlet="componentTypeExpression"></ng-container>
|
|---|
| 1404 | * ```
|
|---|
| 1405 | *
|
|---|
| 1406 | * Customized injector/content
|
|---|
| 1407 | * ```
|
|---|
| 1408 | * <ng-container *ngComponentOutlet="componentTypeExpression;
|
|---|
| 1409 | * injector: injectorExpression;
|
|---|
| 1410 | * content: contentNodesExpression;">
|
|---|
| 1411 | * </ng-container>
|
|---|
| 1412 | * ```
|
|---|
| 1413 | *
|
|---|
| 1414 | * Customized ngModuleFactory
|
|---|
| 1415 | * ```
|
|---|
| 1416 | * <ng-container *ngComponentOutlet="componentTypeExpression;
|
|---|
| 1417 | * ngModuleFactory: moduleFactory;">
|
|---|
| 1418 | * </ng-container>

|

| 1448 | * A [structural directive](guide/structural-directives) that renders
|
|---|
| 1449 | * a template for each item in a collection.
|
|---|
| 1450 | * The directive is placed on an element, which becomes the parent
|
|---|
| 1451 | * of the cloned templates.
|
|---|
| 1452 | *
|
|---|
| 1453 | * The `ngForOf` directive is generally used in the
|
|---|
| 1454 | * [shorthand form](guide/structural-directives#asterisk) `*ngFor`.
|
|---|
| 1455 | * In this form, the template to be rendered for each iteration is the content
|
|---|
| 1456 | * of an anchor element containing the directive.
|
|---|
| 1457 | *
|
|---|
| 1458 | * The following example shows the shorthand syntax with some options,
|
|---|
| 1459 | * contained in an `<li>` element.
|
|---|
| 1460 | *
|
|---|
| 1461 | * ```
|
|---|
| 1462 | * <li *ngFor="let item of items; index as i; trackBy: trackByFn">...</li>
|
|---|
| 1463 | * ```
|
|---|
| 1464 | *
|
|---|
| 1465 | * The shorthand form expands into a long form that uses the `ngForOf` selector
|
|---|
| 1466 | * on an `<ng-template>` element.
|
|---|
| 1467 | * The content of the `<ng-template>` element is the `<li>` element that held the
|
|---|
| 1468 | * short-form directive.
|
|---|
| 1469 | *
|
|---|
| 1470 | * Here is the expanded version of the short-form example.
|
|---|
| 1471 | *
|
|---|
| 1472 | * ```
|
|---|
| 1473 | * <ng-template ngFor let-item [ngForOf]="items" let-i="index" [ngForTrackBy]="trackByFn">
|
|---|
| 1474 | * <li>...</li>
|
|---|
| 1475 | * </ng-template>
|
|---|
| 1476 | * ```
|
|---|
| 1477 | *
|
|---|
| 1478 | * Angular automatically expands the shorthand syntax as it compiles the template.
|
|---|
| 1479 | * The context for each embedded view is logically merged to the current component
|
|---|
| 1480 | * context according to its lexical position.
|
|---|
| 1481 | *
|
|---|
| 1482 | * When using the shorthand syntax, Angular allows only [one structural directive
|
|---|
| 1483 | * on an element](guide/built-in-directives#one-per-element).
|
|---|
| 1484 | * If you want to iterate conditionally, for example,
|
|---|
| 1485 | * put the `*ngIf` on a container element that wraps the `*ngFor` element.
|
|---|
| 1486 | * For futher discussion, see
|
|---|

|
|---|
| 1490 | *
|
|---|
| 1491 | * ### Local variables
|
|---|
| 1492 | *
|
|---|
| 1493 | * `NgForOf` provides exported values that can be aliased to local variables.
|
|---|
| 1494 | * For example:
|
|---|
| 1495 | *
|
|---|
| 1496 | * ```
|
|---|
| 1497 | * <li *ngFor="let user of users; index as i; first as isFirst">
|
|---|
| 1498 | * {{i}}/{{users.length}}. {{user}} <span *ngIf="isFirst">default</span>
|
|---|
| 1499 | * </li>
|
|---|
| 1500 | * ```
|
|---|
| 1501 | *
|
|---|
| 1502 | * The following exported values can be aliased to local variables:
|
|---|
| 1503 | *
|
|---|
| 1504 | * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`).
|
|---|
| 1505 | * - `ngForOf: NgIterable<T>`: The value of the iterable expression. Useful when the expression is
|
|---|
| 1506 | * more complex then a property access, for example when using the async pipe (`userStreams |
|
|---|
| 1507 | * async`).
|
|---|
| 1508 | * - `index: number`: The index of the current item in the iterable.
|
|---|
| 1509 | * - `count: number`: The length of the iterable.
|
|---|
| 1510 | * - `first: boolean`: True when the item is the first item in the iterable.
|
|---|
| 1511 | * - `last: boolean`: True when the item is the last item in the iterable.
|
|---|
| 1512 | * - `even: boolean`: True when the item has an even index in the iterable.
|
|---|
| 1513 | * - `odd: boolean`: True when the item has an odd index in the iterable.
|
|---|
| 1514 | *
|
|---|
| 1515 | * ### Change propagation
|
|---|
| 1516 | *
|
|---|
| 1517 | * When the contents of the iterator changes, `NgForOf` makes the corresponding changes to the DOM:
|
|---|
| 1518 | *
|
|---|
| 1519 | * * When an item is added, a new instance of the template is added to the DOM.
|
|---|
| 1520 | * * When an item is removed, its template instance is removed from the DOM.
|
|---|
| 1521 | * * When items are reordered, their respective templates are reordered in the DOM.
|
|---|
| 1522 | *
|
|---|
| 1523 | * Angular uses object identity to track insertions and deletions within the iterator and reproduce
|
|---|
| 1524 | * those changes in the DOM. This has important implications for animations and any stateful
|
|---|
| 1525 | * controls that are present, such as `<input>` elements that accept user input. Inserted rows can
|
|---|
| 1526 | * be animated in, deleted rows can be animated out, and unchanged rows retain any unsaved state
|
|---|
| 1527 | * such as user input.
|
|---|
| 1528 | * For more on animations, see [Transitions and Triggers](guide/transition-and-triggers).
|
|---|
| 1529 | *
|
|---|
| 1530 | * The identities of elements in the iterator can change while the data does not.
|
|---|
| 1531 | * This can happen, for example, if the iterator is produced from an RPC to the server, and that
|
|---|
| 1532 | * RPC is re-run. Even if the data hasn't changed, the second response produces objects with
|
|---|
| 1533 | * different identities, and Angular must tear down the entire DOM and rebuild it (as if all old
|
|---|
| 1534 | * elements were deleted and all new elements inserted).
|
|---|
| 1535 | *
|
|---|
| 1536 | * To avoid this expensive operation, you can customize the default tracking algorithm.
|
|---|
| 1537 | * by supplying the `trackBy` option to `NgForOf`.
|
|---|
| 1538 | * `trackBy` takes a function that has two arguments: `index` and `item`.
|
|---|
| 1539 | * If `trackBy` is given, Angular tracks changes by the return value of the function.

| 1620 | * provided in a `then` clause, and when false or null,
|
|---|
| 1621 | * Angular renders the template provided in an optional `else` clause. The default
|
|---|
| 1622 | * template for the `else` clause is blank.
|
|---|
| 1623 | *
|
|---|
| 1624 | * A [shorthand form](guide/structural-directives#asterisk) of the directive,
|
|---|
| 1625 | * `*ngIf="condition"`, is generally used, provided
|
|---|
| 1626 | * as an attribute of the anchor element for the inserted template.
|
|---|
| 1627 | * Angular expands this into a more explicit version, in which the anchor element
|
|---|
| 1628 | * is contained in an `<ng-template>` element.
|
|---|
| 1629 | *
|

|
|---|
| 1634 | * ```
|
|---|
| 1635 | *
|
|---|
| 1636 | * Simple form with expanded syntax:
|
|---|
| 1637 | *
|
|---|
| 1638 | * ```
|
|---|
| 1639 | * <ng-template [ngIf]="condition"><div>Content to render when condition is
|
|---|
| 1640 | * true.</div></ng-template>
|
|---|
| 1641 | * ```
|
|---|
| 1642 | *
|
|---|
| 1643 | * Form with an "else" block:
|
|---|
| 1644 | *
|
|---|
| 1645 | * ```
|
|---|
| 1646 | * <div *ngIf="condition; else elseBlock">Content to render when condition is true.</div>
|
|---|

|
|---|

|
|---|
| 1650 | * Shorthand form with "then" and "else" blocks:
|
|---|
| 1651 | *
|
|---|
| 1652 | * ```
|
|---|
| 1653 | * <div *ngIf="condition; then thenBlock else elseBlock"></div>
|
|---|
| 1654 | * <ng-template #thenBlock>Content to render when condition is true.</ng-template>
|
|---|
| 1655 | * <ng-template #elseBlock>Content to render when condition is false.</ng-template>
|
|---|
| 1656 | * ```
|
|---|
| 1657 | *
|
|---|
| 1658 | * Form with storing the value locally:
|
|---|
| 1659 | *
|
|---|
| 1660 | * ```
|
|---|

|
|---|

|
|---|
| 1663 | * ```
|
|---|
| 1664 | *
|
|---|
| 1665 | * @usageNotes
|
|---|
| 1666 | *
|
|---|
| 1667 | * The `*ngIf` directive is most commonly used to conditionally show an inline template,
|
|---|
| 1668 | * as seen in the following example.
|
|---|
| 1669 | * The default `else` template is blank.
|
|---|
| 1670 | *
|
|---|
| 1671 | * {@example common/ngIf/ts/module.ts region='NgIfSimple'}
|
|---|
| 1672 | *
|
|---|
| 1673 | * ### Showing an alternative template using `else`
|
|---|
| 1674 | *
|
|---|
| 1675 | * To display a template when `expression` evaluates to false, use an `else` template
|
|---|
| 1676 | * binding as shown in the following example.
|
|---|
| 1677 | * The `else` binding points to an `<ng-template>` element labeled `#elseBlock`.
|
|---|
| 1678 | * The template can be defined anywhere in the component view, but is typically placed right after
|
|---|
| 1679 | * `ngIf` for readability.
|
|---|
| 1680 | *
|
|---|
| 1681 | * {@example common/ngIf/ts/module.ts region='NgIfElse'}
|
|---|
| 1682 | *
|
|---|
| 1683 | * ### Using an external `then` template
|
|---|
| 1684 | *
|
|---|
| 1685 | * In the previous example, the then-clause template is specified inline, as the content of the
|
|---|
| 1686 | * tag that contains the `ngIf` directive. You can also specify a template that is defined
|
|---|
| 1687 | * externally, by referencing a labeled `<ng-template>` element. When you do this, you can
|
|---|
| 1688 | * change which template to use at runtime, as shown in the following example.
|
|---|
| 1689 | *
|
|---|
| 1690 | * {@example common/ngIf/ts/module.ts region='NgIfThenElse'}
|
|---|
| 1691 | *
|
|---|
| 1692 | * ### Storing a conditional result in a variable
|
|---|
| 1693 | *
|
|---|
| 1694 | * You might want to show a set of properties from the same object. If you are waiting
|
|---|
| 1695 | * for asynchronous data, the object can be undefined.
|
|---|
| 1696 | * In this case, you can use `ngIf` and store the result of the condition in a local
|
|---|
| 1697 | * variable as shown in the following example.
|
|---|
| 1698 | *
|
|---|
| 1699 | * {@example common/ngIf/ts/module.ts region='NgIfAs'}
|
|---|
| 1700 | *
|
|---|
| 1701 | * This code uses only one `AsyncPipe`, so only one subscription is created.
|
|---|
| 1702 | * The conditional statement stores the result of `userStream|async` in the local variable `user`.
|
|---|
| 1703 | * You can then bind the local `user` repeatedly.
|
|---|
| 1704 | *
|
|---|
| 1705 | * The conditional displays the data only if `userStream` returns a value,
|
|---|
| 1706 | * so you don't need to use the
|
|---|
| 1707 | * safe-navigation-operator (`?.`)
|
|---|
| 1708 | * to guard against null values when accessing properties.
|
|---|
| 1709 | * You can display an alternative template while waiting for the data.
|
|---|
| 1710 | *
|
|---|
| 1711 | * ### Shorthand syntax
|
|---|
| 1712 | *
|
|---|
| 1713 | * The shorthand syntax `*ngIf` expands into two separate template specifications
|
|---|
| 1714 | * for the "then" and "else" clauses. For example, consider the following shorthand statement,
|
|---|
| 1715 | * that is meant to show a loading page while waiting for data to be loaded.
|
|---|
| 1716 | *
|
|---|
| 1717 | * ```
|
|---|
| 1718 | * <div class="hero-list" *ngIf="heroes else loading">
|
|---|
| 1719 | * ...
|
|---|
| 1720 | * </div>
|
|---|
| 1721 | *
|
|---|
| 1722 | * <ng-template #loading>
|
|---|
| 1723 | * <div>Loading...</div>
|
|---|
| 1724 | * </ng-template>
|
|---|
| 1725 | * ```
|
|---|
| 1726 | *
|
|---|
| 1727 | * You can see that the "else" clause references the `<ng-template>`
|
|---|
| 1728 | * with the `#loading` label, and the template for the "then" clause
|
|---|
| 1729 | * is provided as the content of the anchor element.
|
|---|
| 1730 | *
|
|---|
| 1731 | * However, when Angular expands the shorthand syntax, it creates
|
|---|
| 1732 | * another `<ng-template>` tag, with `ngIf` and `ngIfElse` directives.
|
|---|
| 1733 | * The anchor element containing the template for the "then" clause becomes
|
|---|
| 1734 | * the content of this unlabeled `<ng-template>` tag.
|
|---|
| 1735 | *
|
|---|
| 1736 | * ```
|
|---|
| 1737 | * <ng-template [ngIf]="heroes" [ngIfElse]="loading">
|
|---|
| 1738 | * <div class="hero-list">
|
|---|
| 1739 | * ...
|
|---|
| 1740 | * </div>
|
|---|
| 1741 | * </ng-template>
|
|---|
| 1742 | *
|
|---|
| 1743 | * <ng-template #loading>
|
|---|
| 1744 | * <div>Loading...</div>
|
|---|
| 1745 | * </ng-template>
|
|---|
| 1746 | * ```
|
|---|
| 1747 | *
|
|---|
| 1748 | * The presence of the implicit template object has implications for the nesting of
|
|---|
| 1749 | * structural directives. For more on this subject, see
|
|---|
| 1750 | * [Structural Directives](https://angular.io/guide/built-in-directives#one-per-element).

|
|---|
| 1954 | * @description
|
|---|
| 1955 | * The `[ngSwitch]` directive on a container specifies an expression to match against.
|
|---|
| 1956 | * The expressions to match are provided by `ngSwitchCase` directives on views within the container.
|
|---|
| 1957 | * - Every view that matches is rendered.
|
|---|
| 1958 | * - If there are no matches, a view with the `ngSwitchDefault` directive is rendered.
|
|---|
| 1959 | * - Elements within the `[NgSwitch]` statement but outside of any `NgSwitchCase`
|
|---|
| 1960 | * or `ngSwitchDefault` directive are preserved at the location.
|
|---|
| 1961 | *
|
|---|
| 1962 | * @usageNotes
|
|---|
| 1963 | * Define a container element for the directive, and specify the switch expression
|
|---|
| 1964 | * to match against as an attribute:
|
|---|
| 1965 | *
|
|---|
| 1966 | * ```
|
|---|
| 1967 | * <container-element [ngSwitch]="switch_expression">
|
|---|
| 1968 | * ```
|
|---|
| 1969 | *
|
|---|
| 1970 | * Within the container, `*ngSwitchCase` statements specify the match expressions
|
|---|
| 1971 | * as attributes. Include `*ngSwitchDefault` as the final case.
|
|---|
| 1972 | *
|
|---|
| 1973 | * ```
|
|---|
| 1974 | * <container-element [ngSwitch]="switch_expression">
|
|---|
| 1975 | * <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|---|
| 1976 | * ...
|
|---|
| 1977 | * <some-element *ngSwitchDefault>...</some-element>
|
|---|
| 1978 | * </container-element>
|
|---|
| 1979 | * ```
|
|---|
| 1980 | *
|
|---|
| 1981 | * ### Usage Examples
|
|---|
| 1982 | *
|
|---|
| 1983 | * The following example shows how to use more than one case to display the same view:
|
|---|
| 1984 | *
|
|---|
| 1985 | * ```
|
|---|
| 1986 | * <container-element [ngSwitch]="switch_expression">
|
|---|
| 1987 | * <!-- the same view can be shown in more than one case -->
|
|---|
| 1988 | * <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|---|
| 1989 | * <some-element *ngSwitchCase="match_expression_2">...</some-element>
|
|---|
| 1990 | * <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
|
|---|
| 1991 | * <!--default case when there are no matches -->
|
|---|
| 1992 | * <some-element *ngSwitchDefault>...</some-element>
|
|---|
| 1993 | * </container-element>
|
|---|
| 1994 | * ```
|
|---|
| 1995 | *
|
|---|
| 1996 | * The following example shows how cases can be nested:
|
|---|
| 1997 | * ```
|
|---|
| 1998 | * <container-element [ngSwitch]="switch_expression">
|
|---|
| 1999 | * <some-element *ngSwitchCase="match_expression_1">...</some-element>
|
|---|
| 2000 | * <some-element *ngSwitchCase="match_expression_2">...</some-element>
|
|---|
| 2001 | * <some-other-element *ngSwitchCase="match_expression_3">...</some-other-element>
|
|---|
| 2002 | * <ng-container *ngSwitchCase="match_expression_3">
|
|---|
| 2003 | * <!-- use a ng-container to group multiple root nodes -->
|
|---|
| 2004 | * <inner-element></inner-element>
|
|---|
| 2005 | * <inner-other-element></inner-other-element>
|
|---|
| 2006 | * </ng-container>
|
|---|
| 2007 | * <some-element *ngSwitchDefault>...</some-element>
