原生javascript星级评分

写个最简单的原生js的星级评分：

<div id="rank" class="pingfen">
    <ul>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
        <li></li>
    </ul>
    <p>加载中</p>
</div>

 

<style type="text/css">
    *{margin: 0;padding: 0;}
.pingfen{  135px; margin:10px auto; height:20px; position: relative;}
.pingfen ul{height:20px; margin-bottom: 10px;}
.pingfen li{  20px; float: left; height: 20px; cursor: pointer; background: url(star.png) no-repeat 0 0; list-style: none;}
.pingfen .active{background: url(star.png) no-repeat 0 -28px;}
.pingfen p{ position: absolute; top:24px; left: 0px;  134px; height: 28px; background: #fff; line-height: 28px; text-align: center; border:1px solid #333; display:none;}
</style>

 

<script>
var aData =["很差","较差","一般","推荐","力推"];

window.onload=function(){
    var oDiv = document.getElementById("rank");
    var aLi = oDiv.getElementsByTagName("li");
    var oP = oDiv.getElementsByTagName("p")[0];
    var i =0;
    for(i=0;i<aLi.length;i++){
        aLi[i].index = i;
            aLi[i].onmouseover = function(){
            oP.style.display = "block";
            oP.innerHTML=aData[this.index];
            for(i=0; i<=this.index;i++){
                aLi[i].className="active";
            }
        };
        aLi[i].onmouseout = function(){
            oP.style.display = "";
            for(i=0; i<aLi.length; i++){
                aLi[i].className="";
            }
        };
        aLi[i].onclick=function(){
            alert(this.index +1);
        };
    }

};
</script>
