我的清单如下...
<ul id="menu">
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
现在，当一个特定的li被点击，我想要active要添加到相同的类并删除active与其他班级相比li元素。另外，当同样li再次点击我想删除active class.
如何，我可以使用ng-click and ng-class?
检查下面的例子：
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', ['$scope', function($scope) {
$scope.setMaster = function(section) {
$scope.selected = section;
}
$scope.isSelected = function(section) {
return $scope.selected === section;
}
}]);
.active {
background-color: orange;
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<ul>
<li ng-repeat="i in ['One', 'Two', 'Three']" ng-class="{active : isSelected(i)}">
<a ng-click="setMaster(i)">{{i}}</a>
</li>
</ul>
<hr> {{selected}}
</div>
