AngularJS - 刷新ng-repeat

Question

I'm using ng-repeat to display a collection of values. My filter options changes according to an ajax call to server. How can I refresh the ng-repeat after the filter parameters have been received?

js fiddle

Template

<div>
<div data-ng-controller="myCtrl">
    <ul>
        <li data-ng-repeat="item in values | filter:filterIds()"> 
            <code>#{{item.id}}</code> Item
        </li>
    </ul>
   </div>
 </div> 
<button ng-click="loadNewFilter()"> filter now</button>

Angular

var app = angular.module('m', []);

app.controller('myCtrl', function ($scope) {
  $scope.values = [
   {id: 1},
   {id: 2},
   {id: 3},
   {id: 4},
   {id: 5},
   {id: 6}
  ];

  $scope.filter = [1,2,3,4,5,6];

  $scope.filterIds = function (ids) {
        return function (item) {
            var filter = $scope.filter;
            return filter.indexOf(item.id) !== -1;          
        }
  }

  $scope.loadNewFilter = function (){
    $scope.filter = [1,2,3];      
   }
});

Answer 1

You need to tell angular that the values have changes:

$scope.loadNewFilter = function (){
    $scope.filter = [1,2,3];      
    $scope.$apply();
}

Answer 2

您已将<button ng-click="loadNewFilter()"> filter now</button>放置在控制器范围之外。

Answer 3

在我的情况下，我在我的ng-repeat中有一个trackBy，不得不将其删除以使其更新。

Answer 4

After receiving your filter called $scope.$apply() as following: It is refresh your scope.

$scope.$apply(function() {
     // your code
});

Answer 5

I didnt need to use $scope.apply() to see the update. What solved this error for me was to make sure:

1. The update was being called from inside the controller.
2. The controller that called the update was the same that contained the ng-repeat.
