|
| - * The `ngRepeat` directive instantiates a template once per item from a
|
| - * collection. Each template instance gets its own scope, where the given loop
|
| - * variable is set to the current collection item, and `$index` is set to the
|
| - * item index or key.
|
| - *
|
| - * Special properties are exposed on the local scope of each template instance,
|
| - * including:
|
| - *
|
| - * <table>
|
| - * <tr><th> Variable </th><th> Type </th><th> Details <th></tr>
|
| - * <tr><td> `$index` </td><td>[num] </td><td> iterator offset of the repeated element (0..length-1) <td></tr>
|
| - * <tr><td> `$first` </td><td>[bool]</td><td> true if the repeated element is first in the iterator. <td></tr>
|
| - * <tr><td> `$middle` </td><td>[bool]</td><td> true if the repeated element is between the first and last in the iterator. <td></tr>
|
| - * <tr><td> `$last` </td><td>[bool]</td><td> true if the repeated element is last in the iterator. <td></tr>
|
| - * <tr><td> `$even` </td><td>[bool]</td><td> true if the iterator position `$index` is even (otherwise false). <td></tr>
|
| - * <tr><td> `$odd` </td><td>[bool]</td><td> true if the iterator position `$index` is odd (otherwise false). <td></tr>
|
| - * </table>
|
| - *
|
| - *
|
| - * [repeat_expression] ngRepeat The expression indicating how to enumerate a
|
| - * collection. These formats are currently supported:
|
| - *
|
| - * * `variable in expression` – where variable is the user defined loop
|
| - * variable and `expression` is a scope expression giving the collection to
|
| - * enumerate.
|
| - *
|
| - * For example: `album in artist.albums`.
|
| - *
|
| - * * `variable in expression track by tracking_expression` – You can also
|
| - * provide an optional tracking function which can be used to associate the
|
| - * objects in the collection with the DOM elements. If no tracking function is
|
| - * specified the ng-repeat associates elements by identity in the collection.
|
| - * It is an error to have more than one tracking function to resolve to the
|
| - * same key. (This would mean that two distinct objects are mapped to the same
|
| - * DOM element, which is not possible.) Filters should be applied to the
|
| - * expression, before specifying a tracking expression.
|
| - *
|
| - * For example: `item in items` is equivalent to `item in items track by
|
| - * $id(item)`. This implies that the DOM elements will be associated by item
|
| - * identity in the array.
|
| - *
|
| - * For example: `item in items track by $id(item)`. A built in `$id()`
|
| - * function can be used to assign a unique `$$hashKey` property to each item
|
| - * in the array. This property is then used as a key to associated DOM
|
| - * elements with the corresponding item in the array by identity. Moving the
|
| - * same object in array would move the DOM element in the same way ian the
|
| - * DOM.
|
| - *
|
| - * For example: `item in items track by item.id` is a typical pattern when
|
| - * the items come from the database. In this case the object identity does
|
| - * not matter. Two objects are considered equivalent as long as their `id`
|
| - * property is same.
|
| - *
|
| - * For example: `item in items | filter:searchText track by item.id` is a
|
| - * pattern that might be used to apply a filter to items in conjunction with
|
| - * a tracking expression.
|
| - *
|
| - * # Example:
|
| - *
|
| - * <ul>
|
| - * <li ng-repeat="item in ['foo', 'bar', 'baz']">{{item}}</li>
|
| - * </ul>

|
| - * The shallow repeater introduces these changes:
|
| - *
|
| - * * The repeater only fires if the identity of the list changes or if the list
|
