Like DHTML, LAMP, or SPA, Ajax is not a technology in itself, but a term that refers to the use of a group of technologies together. Here are 5 excellent Ajax tutorials from IBM that will teach you how to code in this important web development technology.
Mastering Ajax - 5 Part Tutorial from IBMMastering Ajax, Part 1: Introduction to Ajax Ajax, which consists of HTML, JavaScript, DHTML, and DOM, is an outstanding approach that helps you transform clunky Web interfaces into interactive Ajax applications. The author, an Ajax expert, demonstrates how these technologies work together -- from an overview to a detailed look -- to make extremely efficient Web development an easy reality. He also unveils the central concepts of Ajax, including the XMLHttpRequest object. Mastering Ajax, Part 2: Make asynchronous requests with JavaScript and Ajax Most Web applications use a request/response model that gets an entire HTML page from the server. The result is a back-and-forth that usually involves clicking a button, waiting for the server, clicking another button, and then waiting some more. With Ajax and the XMLHttpRequest object, you can use a request/response model that never leaves users waiting for a server to respond. In this article, Brett McLaughlin shows you how to create XMLHttpRequest instances in a cross-browser way, construct and send requests, and respond to the server. Mastering Ajax, Part 3: Advanced requests and responses in Ajax For many Web developers, making simple requests and receiving simple responses is all they'll ever need, but for developers who want to master Ajax, a complete understanding of HTTP status codes, ready states, and the XMLHttpRequest object is required. In this article, Brett McLaughlin will show you the different status codes and demonstrate how browsers handle each and he will showcase the lesser-used HTTP requests that you can make with Ajax. Mastering Ajax, Part 4: Exploiting DOM for Web response The great divide between programmers (who work with back-end applications) and Web programmers (who spend their time writing HTML, CSS, and JavaScript) is long standing. However, the Document Object Model (DOM) bridges the chasm and makes working with both XML on the back end and HTML on the front end possible and an effective tool. In this article, Brett McLaughlin introduces the Document Object Model, explains its use in Web pages, and starts to explore its usage from JavaScript. Mastering Ajax, Part 5: Manipulate the DOM Last month Brett introduced the Document Object Model, whose elements work behind the scenes to define your Web pages. This month he dives even deeper into the DOM. Learn how to create, remove, and change the parts of a DOM tree, and take the next step toward updating your Web pages on the fly!
