请问如何设置cookie实效时间
我的一些代码 请老大看看，我不知道问题在哪？
[php]//1.htm
<Script language="JavaScript" src="http://www.xxx.com/ads.js"></Script>
//ads.js
adslogin();
function adslogin()
{
var ads=GetCookie('adsloginned');
if(ads==null || ads!='haved'){
adstanchu=window.open("http://www.xxx.com/ad.htm");//弹出广告窗
setTimeout("adstanchu.close()",30000);//关闭广告窗口
}
}
function GetCookie (name) {
var arg = name + "=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg)
return getCookieVal (j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}
function getCookieVal (offset) {
var endstr = document.cookie.indexOf (";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
//ad.htm
<html>
<head>
<title>本站广告</title>
<Script language="JavaScript" src="http://www.xxx.com/cloads.js"></Script>
</head>
<body>
<table>
<tr><td>
本站广告<br> <br>

<br>
<br>
</td></tr></table>
<table><tr onclick=closead()><td>
广告代码,点击后12小时内不会有弹出窗口
</td></tr></table>
</body></html>
//cloads.js
function closead(){
var expDays = 12; //设置cookies时间，任意设。
var exp = new Date();
exp.setTime(exp.getTime() + (expDays*60*60*1000));
SetCookie('adsloginned', 'haved', exp);
}
function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
[/php]
本来设置点击弹出广告后不再出现弹窗,但现在好像还是弹出了.
我不知道怎么回事,请老大指点一下.
