JavaScript读取中文cookie时的乱码问题的解决方法

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

//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。
