其实Greasemonkey对Cookie的读改删和javascript的操作是一样的,网上整理了一些函数,可以直接拿来用,整理如下:


//两个参数,一个是cookie的名子,一个是值
function SetCookie(name,value){
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();
}
//取cookies函数
function getCookie(name){
var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
if(arr != null) return unescape(arr[2]); return null;
}
//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();
}
