我可以使用Angular-Filter按多个字段分组吗？

如何解决我可以使用Angular-Filter按多个字段分组吗？

遵循多个字段的示例

angular.module('app',['angular.filter'])

  .controller('MainController', function($scope) {

    $scope.players = [

      {name: 'Gene', team: 'alpha', age: 19},

      {name: 'George', team: 'beta', age: 19},

      {name: 'Steve', team: 'gamma', age: 23},

      {name: 'Paula', team: 'beta', age: 23},

      {name: 'Scruath', team: 'gamma', age: 23}

    ];

 });

<html ng-app="app">

  <div ng-controller="MainController">



<ul ng-repeat="(key, value) in players | groupBy: '[team,age]'">

  <b>Group name: {{key}}</b>

  <br>

  <li ng-repeat="player in value">

    <b>player:</b> {{ player.name }}

    <br>

    <b>team:</b> {{player.team}}

    <br>

    <span ng-if="player.age"><b>age:</b> {{ player.age }}</span>

  </li>

</ul>

  </div>

</body>

</html>

解决方法

我正在使用Angular-Filter的groupBy过滤器。

来自GitHub的示例 ：

$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 team 对玩家集合进行分组。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GROUP BY 团队和年龄。我怎样才能做到这一点？
