AJAX BASIC COMPONENTS AND ITS USE

Ajax is a way of designing and building web pages that are as interactive and responsive as desktop applications.

Youhandle things at the client’s browser whenever you can.

Your pages make asynchronous requests that allow the user to keep working instead of waiting for a response.

You only update the things on your pages that
actually change. And best of all, an Ajax page is built using standard Internet technologies

i)   XHTML


ii)  Cascading Style Sheets


iii)  JavaScript


iv)  The XmlHttpRequest


v)  XML & JSON


vi)  The DOM
