Question

我想为表列添加排序功能，但出现此错误：

[orderBy:notarray] Expected array but received: 0

此外，排序根本不起作用。当上下箭头更改位置时，调试器似乎正在获取正确的信息。

我的HTML：

<th class="text-center"><a style="color:black"
    ng-click="sortColumn('severity')">
    Level
    <span ng-show="sortTable('severity')" class="fa fa-caret-down"></span>
    <span ng-show="sortTable('severity', false)" class="fa fa-caret-up"> 
    </span>
    </a>
</th>
<th><a style="color:black" ng-click="sortColumn('getTimeAgo')">
    Timestamp
    <span ng-show="sortTable('getTimeAgo')" class="fa fa-caret-down"> 
    </span>
    <span ng-show="sortTable('getTimeAgo', false)" class="fa fa-caret-up"> 
    </span>
    </a>
</th>

<tbody ng-repeat="t in Ctrl.notifications | filter : search | 
         filter : Ctrl.customFilter track by $index | 
         orderBy:sortingFn:sortReverse"
         ng-style="$index != 0 ? 'border-top:0px' : ''">

CTRL：

  $scope.sortColumn = (sortBy) => {
    $scope.sortReverse = !$scope.sortReverse;
    $scope.sortBy = sortBy;
  };

  $scope.sortTable = (sortBy, sortReverse = true) =>
    $scope.sortBy === sortBy && $scope.sortReverse === sortReverse;

  $scope.sortAlerts = (alert, sortBy) => {
    switch (sortBy) {
      case 'severity':
        return alert.severity;
      case 'getTimeAgo':
        return alert.getTimeAgo;
      default:
        return alert[sortBy]
    }
  };

  $scope.sortingFn = (alert) => {
    return sortAlerts(alert, $scope.sortBy)
  };

Answer 1

我只是更改了以下内容：

  $scope.sortingFn = (alert) => {
    return sortAlerts(alert, $scope.sortBy)
  };

要

  const sortingFn = (alert) => {
    return sortAlerts(alert, $scope.sortBy)
  };

现在可以使用了。没有错误，没什么...谢谢您的帮助！！

Answer 2

您必须更改tr的重复次数，因此，对tr的阶次效应

<tr ng-repeat="t in Ctrl.notifications | filter : search | 
         filter : Ctrl.customFilter track by $index | 
         orderBy:sortingFn:sortReverse">
    <td>{{t.xxx}}</td>
    <td>{{t.yyyy}}</td>
</tr>

AngularJS | OrderBy不是数组
