8.2. 过滤列表 filter


    filter 是一个过滤内容的标签。



    如果参数是一个字符串,则列表成员中的任意属性值中有这个字符串,即为满足条件(忽略大小写):

    1. <div ng-controller="TestCtrl">
      {{ data | filter: 'b' }} <br />
      {{ data | filter: '!B' }} <br />
      </div>


      <script type="text/javascript">
      var TestCtrl = function($scope){
      $scope.data = [
      {name: 'B', age: 4},
      {name: 'A', age: 1},
      {name: 'D', age: 3},
      {name: 'C', age: 3},
      ];
      }

      angular.bootstrap(document.documentElement);
      </script>


    可以使用对象,来指定属性名, $ 表示任意属性:

    1. {{ data | filter: {name: 'A'} }} <br />
      {{ data | filter: {$: '3'} }} <br />
      {{ data | filter: {$: '!3'} }} <br />


    自定义的过滤函数也支持:

    1. <div ng-controller="TestCtrl">
      {{ data | filter: f }} <br />
      </div>


      <script type="text/javascript">
      var TestCtrl = function($scope){
      $scope.data = [
      {name: 'B', age: 4},
      {name: 'A', age: 1},
      {name: 'D', age: 3},
      {name: 'C', age: 3},
      ];

      $scope.f = function(e){
      return e.age > 2;
      }
      }

      angular.bootstrap(document.documentElement);
      </script>
