Javascript 如何在AngularJS中为ui选择模块定义自定义过滤器？

以下是html中“选择”字段的代码：

<ui-select ng-model="group.selected" theme="selectize" ng-click="searchDisabled(3)" ng-disabled="disabledGroup">
   <ui-select-match placeholder="Choose a group">
       {{$select.selected.name}}
   </ui-select-match>
   <ui-select-choices repeat="group in groups | filter: $select.search">
      <span ng-bind-html="group.name | highlight: $select.search"></span>
      <small ng-bind-html="group.code | highlight: $select.search"></small>
   </ui-select-choices>
</ui-select>

这是我从WebAPI方法GetGroup获得的JSON格式。如何使用自定义筛选器在表列表上显示QR_名称数组

这是我的第一个想法：

testApp.filter('selectGroup', ['$log', function ($log) {
    return function (nameslist, group) {
        group = group || '';
        $log.info('fondslist:', fondslist);
        $log.info('Filter for group:', group);
        var selectList = [];

        angular.forEach(fondslist, function (input) {
            if (group == input.QR_Name['QR_GroupId']) {
                selectList.push(input);
            }
        });
    }
}]);

但是过滤器无法正常工作。

        });
    }
}]);
