AJAX series : Week1

Change

The only unchangeable word in this world!

That too in our IT world, changes will come in each and every second. In web development world, now the word AJAX is being pronounced by everyone. Here, am planning to write something about AJAX with the help of my senior guys on every week. This is first in this series. We will get some basic idea about AJAX in this blog.

Ajax, shorthand for Asynchronous JavaScript and XML, is a Web development technique for creating interactive web applications. The intent is to make web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user makes a change. This is meant to increase the web page's interactivity, speed, and usability.

The Ajax technique uses a combination of:

XHTML(or HTML), CSS, for marking up and styling information.

The DOM accessed with a client-side scripting language, especially ECMAScript implementations such as JavaScript and JScript, to dynamically display and interact with the information presented.

The XMLHttpRequest object to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server.

XML is sometimes used as the format for transferring data between the server and client, although any format will work, including preformatted HTML, and even plain text.
Like DHTML, Ajax is not a technology in itself, but a term that refers to the use of a group of technologies together.

Okies. Take a breath now. My next blog will come with some other subject soon. My next series of AJAX session will be on next week.
