方法太多，ng-click，ng-class，directive实现都可以啊
这是直接写的方法，仅供参考
html:

<p>
    <span ng-class="{'selected':selected==s}" ng-repeat="s in list" ng-bind="s" ng-click="changeStatus(s)"></span>
</p>

js

$scope.list = [1,2,3,4,5];
$scope.changeStatus = function(index){
    $scope.selected = index;
}

添加点击事件。把当前循环的$index和$event传过去。然后自己通过angular jq来就处理就OK啊。

给你个现成的代码：
HTML

<p class='options'>
    <span class='option' ng-class="{'selected':s._selected}" ng-repeat="s in orderStatus" ng-bind="s.l" ng-click="clickStatus(s)"></span>
</p>

JS

$scope.clickStatus = function(prop) {
    prop._selected = !prop._selected;
};

CSS

.option{display:inline-block;border:1px solid green;padding:.25em;margin:.5em .5em 0 0;}
.option.selected{background:green;color:white;}

我正打算写个directive做这个
