|
* @ngdoc directive
|
|
* @name ionReorderButton
|
|
* @parent ionic.directive:ionItem
|
|
* @module ionic
|
|
* @restrict E
|
|
* Creates a reorder button inside a list item, that is visible when the
|
|
* {@link ionic.directive:ionList ionList parent's} `show-reorder` evaluates to true or
|
|
* `$ionicListDelegate.showReorder(true)` is called.
|
|
*
|
|
* Can be dragged to reorder items in the list. Takes any ionicon class.
|
|
*
|
|
* Note: Reordering works best when used with `ng-repeat`. Be sure that all `ion-item` children of an `ion-list` are part of the same `ng-repeat` expression.
|
|
*
|
|
* When an item reorder is complete, the expression given in the `on-reorder` attribute is called. The `on-reorder` expression is given two locals that can be used: `$fromIndex` and `$toIndex`. See below for an example.
|
|
*
|
|
* Look at {@link ionic.directive:ionList} for more examples.
|
|
*
|
|
* @usage
|
|
*
|
|
* ```html
|
|
* <ion-list ng-controller="MyCtrl" show-reorder="true">
|
|
* <ion-item ng-repeat="item in items">
|
|
* Item {{item}}
|
|
* <ion-reorder-button class="ion-navicon"
|
|
* on-reorder="moveItem(item, $fromIndex, $toIndex)">
|
|
* </ion-reorder-button>
|
|
* </ion-item>
|
|
* </ion-list>
|
|
* ```
|
|
* ```js
|
|
* function MyCtrl($scope) {
|
|
* $scope.items = [1, 2, 3, 4];
|
|
* $scope.moveItem = function(item, fromIndex, toIndex) {
|
|
* //Move the item in the array
|
|
* $scope.items.splice(fromIndex, 1);
|
|
* $scope.items.splice(toIndex, 0, item);
|
|
* };
|
|
* }
|
|
* ```
|
|
*
|
|
* @param {expression=} on-reorder Expression to call when an item is reordered.
|
|
* Parameters given: $fromIndex, $toIndex.
