以下是js代码（确保你的js文件调用的地址是否正确）
daifu.js的代码：
document.write('<a href="urladdress" target="_blank"><img src="imgurl1" alt="imgname1" title="imgtitle1"/></a>')
wei.js的代码：
document.write('<a href="urladdress" target="_blank"><img src="imgurl2" alt="imgname2" title="imgtitle2"/></a>')
只是js没写在页面上罢了 这个用的jquery的menu插件<script language="JavaScript" type="text/javascript" src="js/jquery.min.js"></script>
<script language="JavaScript" type="text/javascript" src="js/jquery.menu.js"></script>
<script language="JavaScript" type="text/javascript" src="js/jquery.hoverIntent.minified.js"></script>
去这几个js文件里面找
