  • * {{i}}/{{users.length}}. {{user}} default *
    • * ``` * * The following exported values can be aliased to local variables: * * - `$implicit: T`: The value of the individual items in the iterable (`ngForOf`). * - `ngForOf: NgIterable`: 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 `` 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. * * @see [Structural Directives](guide/structural-directives) * @ngModule CommonModule * @publicApi */ class NgForOf { constructor(_viewContainer, _template, _differs) { this._viewContainer = _viewContainer; this._template = _template; this._differs = _differs; this._ngForOf = null; this._ngForOfDirty = true; this._differ = null; } /** * The value of the iterable expression, which can be used as a * [template input variable](guide/structural-directives#shorthand). */ set ngForOf(ngForOf) { this._ngForOf = ngForOf; this._ngForOfDirty = true; } /** * Specifies a custom `TrackByFunction` to compute the identity of items in an iterable. * * If a custom `TrackByFunction` is not provided, `NgForOf` will use the item's [object * identity](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is) * as the key. * * `NgForOf` uses the computed key to associate items in an iterable with DOM elements * it produces for these items. * * A custom `TrackByFunction` is useful to provide good user experience in cases when items in an * iterable rendered using `NgForOf` have a natural identifier (for example, custom ID or a * primary key), and this iterable could be updated with new object instances that still * represent the same underlying entity (for example, when data is re-fetched from the server, * and the iterable is recreated and re-rendered, but most of the data is still the same). * * @see `TrackByFunction` */ set ngForTrackBy(fn) { if ((typeof ngDevMode === 'undefined' || ngDevMode) && fn != null && typeof fn !== 'function') { // TODO(vicb): use a log service once there is a public one available if (console && console.warn) { console.warn(`trackBy must be a function, but received ${JSON.stringify(fn)}. ` + `See https://angular.io/api/common/NgForOf#change-propagation for more information.`); } } this._trackByFn = fn; } get ngForTrackBy() { return this._trackByFn; } /** * A reference to the template that is stamped out for each item in the iterable. * @see [template reference variable](guide/template-reference-variables) */ set ngForTemplate(value) { // TODO(TS2.1): make TemplateRef>> once we move to TS v2.1 // The current type is too restrictive; a template that just uses index, for example, // should be acceptable. if (value) { this._template = value; } } /** * Applies the changes when needed. */ ngDoCheck() { if (this._ngForOfDirty) { this._ngForOfDirty = false; // React on ngForOf changes only once all inputs have been initialized const value = this._ngForOf; if (!this._differ && value) { try { this._differ = this._differs.find(value).create(this.ngForTrackBy); } catch (_a) { throw new Error(`Cannot find a differ supporting object '${value}' of type '${getTypeName(value)}'.

You can also specify a template that is defined * externally, by referencing a labeled `` 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. * * ``` *
    * ... *
    * * *
    Loading...
    *     * ``` * * You can see that the "else" clause references the `` * 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 `` tag, with `ngIf` and `ngIfElse` directives. * The anchor element containing the template for the "then" clause becomes * the content of this unlabeled `` tag. * * ``` * *
    * ... *

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: `
    *

    Today is {{today | date}}

    *

    Or if you prefer, {{today | date:'fullDate'}}

    *

    The time is {{today | date:'h:mm a z'}}
