代码如下:
function Get_Cookie(name) {
var start = document.cookie.indexOf(name+…=…);
var len = start+name.length+1;
if ((!start) && (name != document.cookie.substring(0,name.length))) return null;
if (start == -1) return null;
var end = document.cookie.indexOf(…;…,len);
if (end == -1) end = document.cookie.length;
return unescape(document.cookie.substring(len,end));
}

function Set_Cookie(name,value,expires,path,domain,secure) {
expires = expires * 60*60*24*1000;
var today = new Date();
var expires_date = new Date( today.getTime() + (expires) );
var cookieString = name + …=… +escape(value) +
( (expires) ? …;expires=… + expires_date.toGMTString() : ……) +
( (path) ? …;path=… + path : ……) +
( (domain) ? …;domain=… + domain : ……) +
( (secure) ? …;secure… : ……);
document.cookie = cookieString;
}

当cookies中保存有中文信息时，会发生乱码，这样修改下就会解决问题
复制代码 代码如下:
//cookie操作函数
function Get_Cookie(name) {
var start = document.cookie.indexOf(name+…=…);
var len = start+name.length+1;
if ((!start) && (name != document.cookie.substring(0,name.length))) return null;
if (start == -1) return null;
var end = document.cookie.indexOf(…;…,len);
if (end == -1) end = document.cookie.length;
return decodeURI(document.cookie.substring(len,end));
}

function Set_Cookie(name,value,expires,path,domain,secure) {
expires = expires * 60*60*24*1000;
var today = new Date();
var expires_date = new Date( today.getTime() + (expires) );
var cookieString = name + …=… +escape(value) +
( (expires) ? …;expires=… + expires_date.toGMTString() : ……) +
( (path) ? …;path=… + path : ……) +
( (domain) ? …;domain=… + domain : ……) +
( (secure) ? …;secure… : ……);
document.cookie = cookieString;
}

主要是把unescape改成了decodeURI。
