Ajax接觸不久，我只是為了挑選一款 Ajax 庫，才收集的資料，并測試，我的測試很簡單，直接看他們網(wǎng)站上的聯(lián)機demo頁面的速度，速度慢的就淘汰！

輔助js:
/wForms 44k（壓縮版）
對表單的js擴充可實現(xiàn)本地校驗等功能。
Ajax:


不錯！速度快!有hint控件。75k. free for non-commercial


感覺好像不錯，也比較小，這個側(cè)重于遠(yuǎn)程客戶端抓取，不過也有控件！而且可以和wForm聯(lián)動。
不過它的網(wǎng)格控件比較弱，不支持鍵盤。

不錯，功能挺全的，但是它的核心js文件有128k，然后還要動態(tài)裝入其它的js, 太大！！速度慢！！
dojo.js 是它的核心(128K)，然后其它widgets是根據(jù)需要裝載，所以在使用的東西太多的情況下顯得慢。
dojo.js:
Dojo's bootstrap system provides some fundamental behaviors, including a package system for dynamically loading scripts.
The Dojo Toolkit is only one of the projects that the Dojo Foundation hosts. In addition to the toolkit, OpenRecord calls the Dojo Foundation home.


不錯，速度快！！不過需要客戶端的XSLT的支持！幸好的是IE和FireFox1.5都支持！！
嘿嘿，才發(fā)現(xiàn)它的lib.js 居然有189k！但是速度一點不慢！
HTMLi (HTML improved) is the open source framework that focuses in:
* Transparent use for HTML designers
* Multi-platform: As it is 100% designed with XSL, it is 0% platform-dependant
* CSS Themes, Multi-Language support
* Fully customizable & extensible
* XML Rich Forms allow simple AJAX interfaces
俺的選擇！俺認(rèn)為使用客戶端處理 XSTL 是速度提升的關(guān)鍵，而且這樣一來， html代碼擴充顯得很自然。


感覺速度還可以！！注意必須要在服務(wù)器上運行！！它用了net.XmlHttpRequest
?JsRIA

JsRia - Javascript Rich Internet Application (since 2005)
[3] JsRIA is a opensource framework enabling rich client interface development. It's pure javascript and is completely independant of the server side technology. The client interface is described by an xml file (or dynamically in javascript if you need that). JsRIA is completely object oriented (javascript components, xml description, css style) and you can very easily build a hierarchy for your interface objects. You also can use AJAX technology to bring really dynamic interface to your users. Numerous functions are provided to parse and use xml flux coming from your server.


速度慢！！但是控件漂亮！！只適合于Intranet,它的js高達幾百k(qooxdoo-0.5.2-build.tar.bz2)，不過qooxdoo-0.5.2-source.tar.bz2,中是拆分成若干js的！！
qooxdoo (Under development; from May, 2005)
qooxdoo is an advanced open-source JavaScript-based GUI framework. It helps you to implement AJAX-enhanced web 2.0 applications - easier than ever before.

* Open-source (LGPL). From various contributors.


Script.aculo.us (from 2005)
Scriptaculous builds on Prototype library to provide a Javascript with comprehensive Ajax coverage.
* Visual Effects (See One-Second Spotlight pattern)
* Drag-And-Drop (See Drag-And-Drop pattern)
* Unit-Testing (See System Test pattern)
* etc.
* Open-source by Thomas Fuchs and others. A project run in conjunction with Ruby on Rails, but can be (and certainly is) used independent of Ruby or RoR.

Google Web Toolkit
Google Web Toolkit (GWT) 是一個Java軟件開發(fā)框架用于開發(fā)類似于Google Maps和Gmail 的AJAX應(yīng)用程序. 你可以用Java編程語言開發(fā)你的界面,然后用GWT編譯器將Java類轉(zhuǎn)換成適合瀏覽器執(zhí)行的JavaScript與HTML.
