提示：您可以先修改部分代码再运行

现在到这里IE老是提示缺少对像，找不到啊，大家帮忙看看，放到层里面就不提示这错误~~，大家帮忙调试一下，谢谢~

好多代码，发点修改建议！
1，获取对象请用标准DOM方法 document.getElementById
2，访问form 请用 document.forms['slideform'],同理 images 也可以使用 document.images['show']
3,你可以在Firefox下使用 Firebug 来调试JS，在firefox下调试通过的JS在IE下一般没问题！

不是这个问题啊，现在就是把它放到层里面就出线这问题，如果不放的话就是好的~~
