求写个图片之间相互切换的js，谢谢啊

6张图片：
A B C;并排排列：
点击A、B、C中的任意一张图片，其本身被相应的图片（A1、A2、A3）替换，其他两张图片必须是原样；类似tab选项卡的那种，怎么写？

解决方案 »

  1.   

    补充一下，界面上初始的时候只有A B C三张图片，A1  B1  C1是用来替换的。

    看一下这个吧<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
