Master Ajax Series

Ajax is undoubtedly the most popular new Web technology. This outstanding method can transform clumsy Web interfaces into interactive Ajax applications. It uses client scripts to exchange data with Web servers. Therefore, you can dynamically update Web pages without refreshing the complete page that interrupts interaction. With Ajax, you can create a richer and more dynamic Web application user interface, and its real-time and availability can even be close to the local desktop application.

Ajax consists of HTML, JavaScript, DHTML, and DOM. Brett McLaughlin, author of this series, is an Ajax expert who demonstrates how these technologies work collaboratively-from an overview to a detailed discussion-to make efficient Web development a reality.

Part 1: Ajax Introduction(March January 4, 2006)
Ajax is composed of HTML, JavaScript, DHTML, and DOM. This outstanding method can convert clumsy Web interfaces into interactive Ajax applications. The author of this article is an Ajax expert who demonstrates how these technologies work collaboratively-from an overview to a detailed discussion-to make efficient Web development a reality. He also unveiled the secrets of Ajax core concepts, including XMLHttpRequest objects.

Part 1: use JavaScript and Ajax to send asynchronous requests(March February 16, 2006)
Most Web applications use the request/Response Model to obtain the complete HTML page from the server. It is often a process of repeatedly clicking a button, waiting for the server to respond, then clicking another button, and then waiting. With Ajax and XMLHttpRequest objects, you can use the request/response model that does not have users waiting for server response. In this article, Brett McLaughlin describes how to create XMLHttpRequest instances that adapt to different browsers, create and send requests, and respond to servers.

Part 1: Advanced requests and responses in Ajax(March 23, 2006)
For many Web developers, they only need to generate simple requests and receive simple responses. However, for developers who want to master Ajax, you must fully understand the HTTP status code, readiness status, and XMLHttpRequest object. In this article, Brett McLaughlin will introduce you to various status codes and show you how the browser processes them. This article also shows the rare HTTP requests used in Ajax.

Part 1: Web response using DOM(March April 10, 2006)
The watershed between programmers (using back-end applications) and Web programmers (writing HTML, CSS, and JavaScript) is long-lasting. However, the Document Object Model (DOM) makes up for this crack, making it practical to use HML at the front end while using XML at the back end, and becoming an extremely effective tool. In this article, Brett McLaughlin introduces the Document Object Model, explains its application in Web pages, and starts to explore its usage in JavaScript.

Part 1: DOM manipulation(March April 27, 2006)
Brett introduced the Document Object Model (DOM) in the previous phase. Its elements define Web pages behind the scenes. He will further explore DOM in this article. Learn how to create, delete, and modify various sections of the DOM tree, and how to implement real-time updates to webpages!

Part 1: Create a DOM-based Web Application(March October 12, 2006)
Brett McLaughlin used a specific DOM application to end his DOM programming trilogy.

Part 1: Using XML in requests and responses (1)(March October 23, 2006)
Brett McLaughlin demonstrates how to use the XML data format to send asynchronous requests.

Part 1: Using XML in requests and responses (2)(March October 23, 2006)
This article focuses onYes indeedA good idea is to return an XML response to the client.

Part 1: Use the Google Ajax Search API(March 1, 2007)
Sending an asynchronous request does not mean that it only interacts with your own server program. In fact, it can also communicate with some public APIs, such as APIs from Google or Amazon, so as to add your own scripts and more functions that server programs cannot provide for Web applications. This article will teach you how to send a request to a public API, such as an API provided by Google and receive its response.

Part 1: Data Transmission Using JSON(March April 9, 2007)
When sending and receiving information in an asynchronous application, you can select plain text and XML as the data format. This phase of understanding Ajax discusses another useful data format, JavaScript Object Notation (JSON), and how to use it to move data and objects more easily in applications.
