<style>
#holder li.current{
background-color:#000000
}
#holder li {
padding: 14px 16px;
float: left;
}
</style>
</head>
<body>
<div id="holder">
<ul><li>aaa</li></ul>
<ul><li>aaa</li></ul>
</div>
<script type="text/javascript">
var holder = document.getElementById("holder");
var td = holder.getElementsByTagName("li");
for(var i = 0; i < td.length; i++){
var obj = td[i];
obj.onmouseover = function(){this.className = "current";};
obj.onmouseout = function(){this.className = "";};
}
</script>
</body>
</html>
上面这段代码是一个鼠标滑过背景变色的效果，但是只能用id控制（id="holder"），能不能修改为class的，因为页面好多地方要用同一个效果
我菜鸟，求详细方法
