前台代码：
<div id="soutu">
<div id="zhuan">这里只是放一张图片而已
<img alt="" src="../Images/a.jpg?http://www.xvna.com" width="750" height="330" />
</div>
</div>
<div id="tuzi">这里调用脚本函数
<a href="#" onmousemove="showLink(1)" class="aTaohang">1</a>
<a href="#" onmousemove="showLink(2)"class="aTaohang">2</a>
<a href="#" onmousemove="showLink(3)" class="aTaohang">3</a>
<a href="#" onmousemove="showLink(4)" class="aTaohang">4</a>
</div>
脚本：这里可我做成一个JS文件，放在前台调用，这样就方便点。
