Thread: Ajax

The term Ajax has come to represent a broad group of web technologies that can be used to implement a web application that communicates with a server in the background, without interfering with the current state of the page.The use of Ajax has led to an increase in interactive animation on web pages. Data is retrieved using the XMLHttpRequest object or through the use of Remote Scripting in browsers that do not support it. Despite the name, the use of JavaScript and XML is not actually required, nor do the requests need to be asynchronous.

Benefits:

1. Using Ajax, a web application can request only the content that needs to be updated, thus drastically reducing bandwidth usage and load time.

2. The use of asynchronous requests allows the client's Web browser UI to be more interactive and to respond quickly to inputs, and sections of pages can also be reloaded individually. Users may perceive the application to be faster or more responsive, even if the application has not changed on the server side.

3. The use of Ajax can reduce connections to the server, since scripts and style sheets only have to be requested once.

Ajax is certainly a bless for web developers developing faster websites. For most of my applications I try to use as much ajax as possible.

Hi...
Here is also some information regarding AJAX such a powerful tool after PHP..AJAX, as mentioned before, is not a new programming language but a relatively new technique for creating faster, better and dynamic web applications. If you are really interested in learning AJAX, then it would be better for your learning experience if you develop some understanding of HTML, XHTML, XML and JavaScript. If you have the basic understanding of these languages then you can have a go with AJAX.

AJAX has replace javascript and it is one of the most hot topic in web development
