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 requests 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) and CSS, for marking up and styling information.
-
The Document Object Module accessed with a client-side scripting language, implementations such as JavaScript, to dynamically display and interact with the information presented.
-
The XML Http Request object is used to exchange data asynchronously with the web server. In some Ajax frameworks and in certain situations, an object is used instead of the XML Http Request object to exchange data with the web server, and in other implementations, tags may be used.
-
XML is sometimes used as the format for transferring data between the server and client, although any format will work, including preformatted HTML, plain text,JSON and even EBML. These files may be created dynamically by some form of server-side scripting.
