效果代码如:http://www.b-y-d.com/blog/article.asp?id=86
我的问题是
(1):如何设置子菜单的背景颜色

(2):如何设置子菜单中,鼠标移上去菜单的背景色和鼠标移走后菜单的颜色

拜托各位了，代码如下

<script language="javascript">
// JavaScript Document

startList = function() {
if (document.all&&document.getElementById) {
navRoot = document.getElementById("nav");
for (i=0; i<navRoot.childNodes.length; i++) {
node = navRoot.childNodes[i];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
}
node.onmouseout=function() {
this.className=this.className.replace(" over", "");
}
}
}
}
}
window.onload=startList;
</script>
<style type="text/css">

</style>
</head>

<body>
<ul id="nav" >
<li><a href="#">Home</a></li>
<li><a href="#">About</a>
<ul>
<li><a href="#">History</a></li>
<li><a href="#">Team</a></li>
