Javascript对cookies的常用操作：
//设置Cookie
function setCookie(c_name,value,expiredays)
{
var exdate=new Date()
exdate.setDate(exdate.getDate()+expiredays)
document.cookie=c_name+ "=" +escape(value)+
((expiredays==null) ? "" : "; expires="+exdate.toGMTString())
}
//获取Cookie
function getCookie(objName){
var arrStr = document.cookie.split("; ");
for(var i = 0;i < arrStr.length;i ++){
var temp = arrStr[i].split("=");
if(temp[0] == objName) return unescape(temp[1]);
}
return null;
}
//删除Cookie
function delCookie(name){
var date = new Date();
date.setTime(date.getTime() - 10000);
document.cookie = name + "=a; expires=" + date.toGMTString();
}
