题目有点简单，不清楚具体问题是什么。
下面写了一下关于鼠标移入移出，li变色的例子，仅供参考。
思路：当鼠标移入时，修改li的背景色，直接用background修改就可以。
鼠标移出时，恢复原来li的背景色。

<script>
var oUl = document.getElementById('ul');
var aLi = oUl.children;
for(var i=0;i<aLi.length;i++){
aLi[i].onmouseover = function(){
this.style.background = 'red';
};
aLi[i].onmouseout = function(){
this.style.background = '';
};
}
