［@100@］,请帮我改一下改变背景色的JS，我初学，谢谢了。
一个test.aspx一个one.css和two.css
one.css中
body
{
background:#CCFFCC;
}
two.css
body
{
background:#000000;
}
test.aspx中
<html xmlns= "http://www.w3.org/1999/xhtml " >
<head runat= "server ">
<title> 无标题页 </title>
<script language=javascript>
function ChangeColor(i)
{
document.all.csss.href = "a.css ";
}
</script>
</head>
<body>
<form id= "form1 " runat= "server ">
<div>
<input id= "Button1 " type= "button " value= "button " onclick= "ChangeColor( 'one.css ') "/>
<input id= "Button2 " type= "button " value= "button " onclick= "ChangeColor( 'two.css ') "/> </div>
</form>
</body>
</html>
写到这不会写了，请高人帮我一下，想通过JS实现动态选择不同的CSS样式文件。谢谢了。在线，对了立即给分。

@LZ
好象也没有这个document.all.csss.href ？？
LZ是要换肤吧，送你断代码
<HTML>
<HEAD>
<link ID= "skin " rel= "stylesheet " type= "text/css ">

在同级目录中放css.css，css１.css，css２.css，css３.css
css.css
body{background:#ffccff;}
css１.css
body{background:#00ccff;}
css2.css
body{background:#00aaff;}

[解决办法]
LS的方法很详细 皮肤的样式修改后存到了cookies里面 只要没过期，下次登陆自动就应用了上次选择的样式表
不过对新手来说不太容易理解吧
LZ可以这样
function a()
{
document.style.body.background-color=#CCFFCC; //手打代码，不清楚是不是这样写，应该可以.的出来
}
然后调用就可以了
如果背景颜色有多个
function a(i)
{
if(i==1)
.......
不过页面重新page_load后还是原来的颜色， 所以建议LZ还是用LZ的方法，代码已经给你了，研究一下吧
