这个是由asp二级侧拉菜单改的
<script language="javascript">
// javascript document
startlist = function() {

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>
