javascript - 验证 $index 并设置样式

Question

我试图突出显示表格行，但很难将其转换为指令内的 Angular js。检查伪代码:

if(highlight.indexOf($index) != -1) set .highlight css class

这是我的代码示例:

$scope.highlight  = [0,2,3]

.highlight {
  color: red;
}

<table class="ui celled table">
  <thead>
    <tr>
      <th>AAA</th>
      <th>BBB</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="a in as track by $index"> <!-- The ng-class needs to be here, but where should i do the verification? -->
      <td>{{a}}</td>
      <td>{{b[$index]}}</td>
    </tr>
  </tbody>
</table>

Answer 1

使用ng-class在ng-repeat之后:

<tr ng-repeat="a in as track by $index" ng-class="{highlight: highlight.indexOf($index) > -1}">
