angularjs – 我可以使用Angular-Filter对多个字段进行分组吗？

我正在使用 Angular-Filter的 groupBy过滤器.

GitHub的例子：

$scope.players = [
  {name: 'Gene',team: 'alpha'},{name: 'George',team: 'beta'},{name: 'Steve',team: 'gamma'},{name: 'Paula',{name: 'Scruath',team: 'gamma'}
];

<ul>
  <li ng-repeat="(key,value) in players | groupBy: 'team'">
    Group name: {{ key }}
    <ul>
      <li ng-repeat="player in value">
        player: {{ player.name }}
      </li>
    </ul>
  </li>
</ul>

因此,该示例按团队分组球员集合.想象一下,每个玩家对象都有一个年龄属性：

$scope.players = [
  {name: 'Gene',team: 'alpha',age: 19},team: 'beta',team: 'gamma',age: 23},age: 23}
];

我想按团队和年龄分组.我怎样才能做到这一点？

按照多个字段的示例

angular.module('app',['angular.filter'])
  .controller('MainController',function($scope) { 
    $scope.players = [
      {name: 'Gene',age: 23}
    ];
 });
