原来的javascript函数如下：
//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 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。

在《JavaScript: The Definitive Guide, 4th Edition》中写到：
In client-side JavaScript, a common use of escape( ) is to encode cookie values, which have restrictions on the punctuation characters they may contain.
在客户端脚本程序中，escape( )函数可以被用作对具有不规范标点的cookie进行编码。（就像我们函数中所用到的一样）
Although the escape( ) function was standardized in the first version of ECMAScript, it has been deprecated and removed from the standard by ECMAScript v3. Implementations of ECMAScript are likely to implement this function, but they are not required to. In JavaScript 1.5 and JScript 5.5 and later, you should use encodeURI( ) and encodeURIComponent( ) instead of escape( ).
虽然escape( ) 已经在ECMAScript中被标准化，但是在ECMAScript v3中，escape( ) 被剔出，如果需要在JavaScript 1.5 和JScript 5.5以后的版本中使用这个函数，建议使用encodeURI( )和encodeURIComponent( )。
今天在Thinkbase.net发现一个在线测试JavaScript正则表达式的页面，确实不错，收藏。
