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( )。

Alex says it best:

After a complete re-think about the purpose and value of Dojo, and after
months of grueling ground-up work on the part of the entire Dojo team,
I’m happy, proud, and excited to announce that Dojo 0.9.0 is available and AOL is already hosting 0.9 in their CDN.

For those porting Dojo applications from previous version of the
toolkit, you can refer to the Porting Guide for help on where APIs landed in the shuffle

In may cases, you’ll need less code overall to get the same thing done
(or done better), and Bill Keese (Dijit Project Lead) has put together
a great overview of what’s new and awesome.

The quick rundown of 0.9 features:

Dijit

• unified look and feel for all widgets
• ambitious a11y and i18n features in every Dijit widget
• a mature CSS-driven theme system with multiple, high-quality themes
• huge improvements in system performance
• data-bound widgets
• Declarations for lightweight widget writing
• a new page parser that allows instances of any class, not just widgets
• no magic

Core

• reduced API surface area (easier to remember and use)
• dojo.query() always available, returns real arrays
• from-scratch high-performance DnD system
• Base (dojo.js) is 25K on the wire (gzipped)
• dojo.data APIs finalized
• new build system
• new test harness for both CLI and browser use
• dojo.behavior now marked stable and based on dojo.query
• excellent animation APIs with Color animations in Base (always available)
• all the features you’ve come to count on from Dojo (RPC, JSON-P, JSON, i18n, formatting utilities, etc.)

DojoX

• high quality implementations of previously experimental features: gfx (portable 2D drawing), data wires, offline, storage, cometd, etc.
• dojox.gfx now includes Sliverlight support
• many more features and improvements than there’s room for here.

2007年7月3日，dojo发布了0.9 beta版，详情请看dojo官方介绍:Dojo 0.9 lands softly。

dojo 0.4到dojo 0.9beta变化比较大，可以参考:Dojo Porting Guide: 0.4.x to 0.9

dojo 0.9beta在向更小体积，更快速度的目标发展，确实，dojo的框架不错，就是太大了。对于普通web应用的ajax框架，都是够用就好，大了反而是缺点。

新特性：
1.SPEED:
速度是关键
2.Accessibility:
3.Theming:
这个貌似不错，可以看看下面这些demo，都可以定制我们自己的样式：
a.日历
b.取色器
c.编辑器
4.Documentation:
