记录cookies实现退出弹出“设为主页”代码

var end = document.cookie.indexOf( ';', len );
if ( end == -1 ) end = document.cookie.length;
return unescape( document.cookie.substring( len, end ) );
}
function SetCookie(name,value)//两个参数，一个是cookie的名子，一个是值
{
var Days = 1; //此 cookie 将被保存 1 天
var exp  = new Date();
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function setpage(aa,str){
//注意，只对IE有效，FF需要修改浏览器设置
aa.style.behavior="url(#default#homepage)";
var bb=getCookie("username");   //读取cookies
if (bb!='easyplay8er')
