24小时弹出一个窗口的代码

<SCRIPT LANGUAGE=”javascript”>
<!– NETBEI.COM
var Time=86400; //设置每次弹出的相格的时间以秒为单位,现在是一天
function Set(){
var Then=new Date();
Then.setTime(Then.getTime()+Time*1000);
documents.cookie=”netbei=1;expires=”+Then.toGMTString();
}
var cookieString=new String(documents.cookie);
var cookieHeader=”netbei=”;
var beginPosition=cookieString.indexOf(cookieHeader);
if (beginPosition<0){
window.open(“http://bbs.netbei.com/”,””,”width=400,height=300″); //设置弹出窗口的大小
Set();
}

2、可设置同一IP弹出窗口次数和时间的弹窗代码
