有幾多人對 AJAX 有興趣或有研究的呢?

其實好多人誤解左 AJAX 一定要係 d 好 cool 既 user interface﹐但其實 AJAX 本身只不過係 利用 Javascripts 同 browser 既 XMLHttpRequest object 去進行 asynchronous request﹐響 background 向 server 提取資料﹐無需 refresh 用戶所在既頁面﹐就可以隨意顯示或更新頁面內容。  當我地見到果 dAJAX toolkit 例如 dojo, scriptaculous...等﹐其實只係一堆 DHTML 利用/配合 AJAX 做出黎既效果。

所以呢個 topic 我只係想暫時 focus 響 AJAX﹐睇下有無人可以交流下心得...

我自己就有少少經驗但有時有 d 古怪問題﹐想搵人傾下咁囉。  

Talking about pure AJAX, I have little exp.
Usually I use scriptaculous. most what I need is there.

Ok!  Scriptaculous is based on the Prototype libraries.  So when talking about pure ajax, do you new up the Ajax.Request() that comes with prototype?  Or you create the ActiveXObject("Microsoft.XMLHTTP") / XMLHttpRequest from scratch?

I have play some with (long time ago) on click event on button and that will call a javascript function. that function active a php script and output xml.. through that xml(result) update the page.

something like that

最常用既都係 document.getElementByID("xxx".value = "123"..
就可以直接update display value..

I usually creates a XMLHttpRequest / ActiveXObject, send the request to the server, parse the xml from the response and update the page accordingly.
