<!doctype html>

<script type="text/javascript" src="angular.min.js"></script>
<script>
var myApp = angular.module("myApp", []);
myApp.controller("testCtrl", function($scope){
$scope.data = [0,1,2,3,4];
$scope.isCurrent = function(index){
$scope.bg = [];
$scope.bg[index] = 'current';

<body ng-app="myApp">
<ul ng-controller="testCtrl">
<li ng-repeat="item in data" ng-class="bg[$index]" ng-click="isCurrent($index)"></li>
</ul>
</body>
</html>

上面的写复杂了，

html:

<li ng-repeat="item in data" ng-class="{activedClass:$index==activerow}" ng-click="isCurrent($index)"></li>
js:

$scope.activerow=0; //默认第一个项目加上class
$scope.isCurrent = function(index){<span style="white-space:pre">	</span><pre name="code" class="javascript">$scope.activerow = index;
}
