以下HTML，Javascript和JSON可以正确呈现，但该过滤器根本不起作用。我们做错了什么？
<div data-ng-controller="dashboard_controller"> <h1> Catalogs <input type="text" data-ng-model="catalog_filter" placeholder="Filter Distributors"> </h1> <div class="catalogs_listing"> <ul data-ng-repeat="catalog in catalogs | filter:catalog_filter"> <li><a href="{{catalog.distributor_id}}/d/products/catalog_view/{{catalog.uid}}"> <div class="catalog_thumb"> <div class="catalog_thumb_image"> <img src="{{catalog.thumb_image}}" /> </div> </div> <div class="catalog_info"> <h2>{{distributors[catalog.distributor_id].name}} <span>{{catalog.products_count}}p</span> </h2> <p>{{catalog.name}}</p> </div> </a> </li> </ul> </div> </div>
Javascript：
app.controller('dashboard_controller', function ($scope, $http) { $http.get('./api/distributors/my').then(function (res) { $scope.distributors = res.data; }); $http.get('./api/dashboard/catalogs').then(function (res) { $scope.catalogs = res.data; }); });
这两个JSON：

角度过滤器无法将对象的对象作为输入。ng- repeat可以渲染它们，但是过滤器需要一个对象数组。解决此问题的最简单方法是让服务器返回没有命名键的数组。您还可以在每次请求后将响应转换为角度（更昂贵）。
