我有3个链接，第一个有.active类。当您单击2和3时，数字1将丢失.active类。现在，如果你单击2或3，它们将正确更新，但1仍然有活动类：（

<ul>
  <li class="active"
      data-ng-class="{'active' : toggleObject == 1}"
      data-ng-click="toggleObject = 1">a click 1
  </li>
  <li data-ng-class="{'active' : toggleObject == 2}"
      data-ng-click="toggleObject = 2">a click 2
  </li>
  <li data-ng-class="{'active' : toggleObject == 3}"
      data-ng-click="toggleObject = 3">a click 3
    <br>
  </li>
</ul>

您需要从第一个li中删除该类，而是将控制器中的toggleObject设置为1。

function HolaCtrl($scope){
  $scope.toggleObject = 1;
}

<li data-ng-class="{'active' : toggleObject == 1}" data-ng-click="toggleObject = 1">a click 1<br>
</li>
<li data-ng-class="{'active' : toggleObject == 2}" data-ng-click="toggleObject = 2">a click 2
<br>
</li>
<li data-ng-class="{'active' : toggleObject == 3}" data-ng-click="toggleObject = 3">a click 3
        <br>
</li>

如何使用ng-class ng-click删除类？
