用cookie来保存radio的值，在Checked(）函数中进行设置，可是一刷新，又回到原来的状态，cookie无法保存下来，请问是哪出错了？望大侠帮帮忙~~谢谢！！！
附代码如下：
<script language="javascript">
<!--
function SetCookie(name,value)//两个参数，一个是cookie的名子，一个是值
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function GetCookie(name)//取cookies函数
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;} function Checked(Txt)
{
var Checks = document.getElementsByName("face");
Txt = GetCookie("Txt");
for(var i=0;i<Checks.length;i++)
{
if(Txt == document.frm.face[i].value)
{
SetCookie("Txt",Txt)
document.frm.face[i].checked = true;
}
}
}
//-->
</script>
<BODY onload="Checked('12234');">
<form name="frm">
<input type=radio name=face value="12234">
<input type=radio name=face value="222">
<input type=radio name=face value="1334">
</form>
