首先做首要页面，先准备一些图片，做一个图片交换的菜单栏
然后在与之间插入以下两个JS文件
<script language="JavaScript" src="images/js/menu.js"></script> //menu.js代码附后
<script language="JavaScript" src="images/js/mm_menu.js"></script> //mm_menu.js代码附后
最后在后面body后加入如下代码：
<script language="JavaScript1.2">mmLoadMenus();</script>
//以下代码为menu.js内具体代码！
// JavaScript Document

//以下代码为mm_menu.js 内具体代码！
