js cookies 操作函数
//取cookies
function getCookie(name)
{
var arr = document.cookie.match(new RegExp("(^| )" + name + "=([^;]*)(;|$)"));
if (arr != null)
return unescape(arr[2]);
return null;
}
//设置cookies 两个参数，一个是cookie的名子，一个是值
function SetCookie(name, value, time)
{
var exp = new Date();
exp.setDate(exp.getDate() + time);
document.cookie = name + "=" + escape(value) + ";expires=" + exp.toGMTString();
}
//删除cookie
function delCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval = getCookie(name);
if (cval != null) document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
}
