在angularjs应用中如何做选择评星的效果

由于是在开发的时候被临时想出来的做法，套用了jq所以代码很糟糕，没有很好的活用ng，等以后有空了再慢慢改吧
<div class="right" id="score">
    <img class="allimgstrat imgstrat0" src="img/start.png" ng-click="theScore(0)" alt=""/>
   ...
    <img class="allimgstrat imgstrat4" src="img/start.png" ng-click="theScore(4)" alt=""/>
</div>


$scope.theScore=function(num){
    $(".allimgstrat").attr("src","img/start.png");
    $scope.comment.stars=0;
    for(var nums=0;nums<=num;nums++){
        var classname= ".imgstrat"+nums;
        $(classname).attr("src","img/start-full.png");
        $scope.comment.stars=nums+1;
    }

}
