//写cookies函数
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() +";path=/100class";//path是cookie的访问路径
}
//取cookies函数
function getCookie(name)
{
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null)
return unescape(arr[2]);
else
return null;
}
//删除cookie
function deleteCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null)
document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
