Question

我在ng-repeat中有自定义过滤器。我需要找出返回数组的长度。怎么做？这是html：

 <div  ng-repeat="item in vm.work_items | itemsInFolder: search">
      <div>item.name</div>
 </div>
 <div>{{returnedArray.length}}</div> //I need set returned value here.

过滤器：

 .filter('itemsInFolder', function($window, NamesService) {
        return function (items, input) {
            if(!input) {
                return items;
            } else {
            var out = [];
            items.forEach(function(item){
             //here goes some custom logic, which returns array;
             out.push(item);
               }
          return out;
        }
  });

Angular 1.3中的新功能，您可以使用ng-repeat选项扩展as指令。

<div ng-repeat="item in vm.work_items | itemsInFolder: search as results">
    <div>item.name</div>
</div>

<p>{{results.length}}</p>

如何获取从过滤器数组返回的长度？
