Question

来自GitHub的示例：

$scope.players = [
  {name: 'Gene', team: 'alpha'},
  {name: 'George', team: 'beta'},
  {name: 'Steve', team: 'gamma'},
  {name: 'Paula', team: 'beta'},
  {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，该示例通过团队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},
  {name: 'George', team: 'beta', age: 19},
  {name: 'Steve', team: 'gamma', age: 23},
  {name: 'Paula', team: 'beta', age: 23},
  {name: 'Scruath', team: 'gamma', age: 23}
];

我希望按团队和年龄进行分组。我怎么能这样做？

Answer 1

按照多个字段的示例

＆＃13;

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}
    ];
 });

    <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>

尝试以下我假设您希望使用多个值作为条件创建组

 get: function(document, oData) {
        var self = this;
        var oInnerHTML;
        if (oData) {
            var oParsedHTML = this._parseHtml(document);
            oInnerHTML = oParsedHTML;
            oData.forEach(function(configEntry) {
                oInnerHTML = self._routeExtentionTypes(configEntry, oInnerHTML);
            });
            oInnerHTML = this._convertBackToHtml(oInnerHTML);
        } else {
            oInnerHTML = document;
        }
         return oInnerHTML
    }

我可以使用Angular-Filter按多个字段进行分组吗？
