还有一种JS方法：将上述的li:hover改为.lihover 然后再添加以下代码即可：
<script type="text/javascript">
window.onload=function(){
var oli=document.getElementsByTagName(‘li‘);
for(var i=0;i<oli.length;i++){
oli[i].onmouseover=function(){
this.className="lihover";
}
oli[i].onmouseout=function(){
this.className="";
}
}
}
</script>
