                                   AJAX Technology

  •AJAX stands for Asynchronous Java script And Xml

AJAX is not a new language , rather it is a new style of programming made popular by Google in 2007 and today it is the backbone of every dynamic web application

Need of AJAX:

When java script was released , it was able to interact with html but it had no way of communicating with the server.

 Thus , the only way html page could communicate with a server side script like php or jsp was to make html form containing a submit button and generating get or post request 

• when the user clicks submit button a new page is generated by the server containing the desired results

•But , sometimes on slow networks this could take time .

•Moreover most of the time the new page has 90% elements same as the previous page only 10% of data gets changed.

Exercise of AJAX:

•Write an AJAX based application to get the date from server and display it on the page.

   Example:-

       <%@ page import="java.util.*,java.text.*" %>

<%

Date today=new Date();

SimpleDateFormat sdf=new SimpleDateFormat("dd-MMM-yyyy");

String str=sdf.format(today);

%>

<h3>Date  at server is <%= str %></h3>
