AJAX for Beginners (Part 1) - Understanding ASP.NET AJAX Server Controls.

Background Desktop applications and web applications have one major difference and that is the stateless nature of web applications. AJAX, i.e., Asynchronous JavaScript and XML, is the technique that can be used to have communication between the client and server without needing a postback. AJAX is a set of W3C complaint technologies that facilitate this asynchronous communication between the client and server. So as an ASP.NET developer why should one learn to use AJAX?

[程式][JQuery] JQuery中的Ajax的基礎運用。提供範例程式下載。 @ 四處流浪的阿基。I am Vagrant Walker. 在這個號稱 web 2.0 的時代，寫網站，尤其是還用到了大量的 JavaScript，如果與使用者的互動還沒有用到 Ajax 技術的話，似乎是一件很神奇的事，至於 Ajax 是什麼東西？

想瞭解的人可以到這裡去看維基百科上的解釋，這篇就專心寫一下 jQuery 中的 Ajax 部份。 程式範例：下載點 這個 PHP 程式很簡單， recive.php它只回應一個index.php傳入的字串，所以我們現在要做的事情便是：按下按鈕後，向 server 端的 index.php 發出一個 request，然後把它回應的東西放alert出來。 所以我們把 Submit 函式的部份寫成這樣：index.php ajax當中的參數： url：指定要進行呼叫的位址。 Data：傳送至Server的資料，會自動轉為query string的型式，如果是GET請求還會幫你附加到URL。 Type：請求方式，POST/GET。 DataType：預期Server傳回的資料類型，如果沒指定，jQuery會根據HTTP MIME Type自動選擇以responseXML或responseText傳入你的success callback。 Success：請求成功時執行函式。 Error：請求失敗時執行函式。 Complete：請求完成時執行的函式(不論結果是success或error)。 BeforeSend：發送請求之前可在此修改XMLHttpRequest物件，如添加header等，你可以在此函式中return flase取消Ajax request。
