建议我必须做哪些改变才能实现这一点。请参阅控制器中的JSFIDLE：

$scope.someVar = true;

在模板中：

<li ng-click="someVar = !someVar"></li>
    <i ng-class="{'fa-angle-left': someVar, 'fa-angle-down': !someVar}"></i>
</li>

单击该

li

后，它将在作用域上切换变量

someVar

，并根据控制器中的

someVar

是真还是假，使类在

上更改：

$scope.someVar = true;

在模板中：

<li ng-click="someVar = !someVar"></li>
    <i ng-class="{'fa-angle-left': someVar, 'fa-angle-down': !someVar}"></i>
</li>

单击该

li

后，它将在作用域上切换变量

someVar

，并根据

someVar

是真是假，使类在
