What is AJAX?
Asynchronous JavaScript And XML, or its acronym, Ajax (Pronounced A-jacks), 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 like 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 commonly used as the format for transferring data back from the server, although any format will work, including preformatted HTML, plain text, JSON and even EBML.
Why ajax is so attractive to developers and users?
Bandwidth utilization
Local html stays on its place, javascript calls the data from remote server, ajax pages apear, load and work much more faster, because of the data(small with no style and useless information in it
The ajax technique cuts down the bandwidth and speed up your pages
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.
