Technologies That Make Up Ajax

Based on this general umbrella term, take a look at the specific items that make up Ajax:



@  XmlHttpRequest—XmlHttpRequest allows the browser to communicate to a back-end server.
This object allows the browser to talk to the server without requiring a postback of the entire
web page. With Internet Explorer, this capability is provided by the MSXML ActiveX component.
With the Mozilla Firefox and other web browsers, this capability is provided by an object
literally called XmlHttpRequest. The XmlHttpRequest object is modeled after the MSXML
component. The client-side JavaScript libraries hide the differences between the various browser
environments. Sometimes these communications are done through a hidden FRAME or IFRAME.


@ JavaScript—JavaScript provides the capabilities to communicate with the back-end server.
The JavaScript must be version 1.5 or later. Although JavaScript is not specifically required, it
is needed from the standpoint that JavaScript is the only client-side scripting environment supported
across the major modern web browsers. There are other client script languages; however,
these are not supported across all browsers.

@ DHTML/DOM support—The browser must support the ability to dynamically update form
elements, and the ability to do this in a standard way comes through the support for the
Document Object Model (DOM). By supporting the DOM, it becomes easy for developers to
write a single piece of code that targets multiple browsers.

@ Data transport with XML or JSON—Using XML allows for the ability to communicate with
the web server in a standard mechanism. There are situations where the JavaScript Object
Notation (JSON) is used as the communication notation instead of straight XML.

Advantages of Ajax

The advantages of Ajax over classical web based applications are:

@ Asynchronous—Ajax allows for the ability to make asynchronous calls to a web server. This
allows the client browser to avoid waiting for all data to arrive before allowing the user to act
once more.

@ Minimal data transfer—By not performing a full postback and sending all form data to the
server, the network utilization is minimized and quicker operations occur. In sites and locations
with restricted pipes for data transfer, this can greatly improve network performance.

@ Limited processing on the server—With the fact that only the necessary data is sent to the
server, the server is not required to process all form elements. By sending only the necessary
data, there is limited processing on the server. There is no need to process all form elements,
process the viewstate, send images back to the client, and no need to send a full page back to
the client.

@ Responsiveness—Because Ajax applications are asynchronous on the client, they are perceived
to be very responsive.

@ Context—With a full postback, the user may lose the context of where they are. The user
may be at the bottom of a page, hit the Submit button, and be redirected back to the top of
the page. With Ajax there is no full postback. Clicking the Submit button in an application that
uses Ajax will allow the user to maintain their location. The user state is maintained, and the
user is no longer required to scroll down to the location that he or she was at before clicking
Submit.

Introduction To Ajax

Ready To Learn About this thing called AJAX. But what exactly is it? 

The term AJAX refers to a loose grouping of technologies that are used to create dynamic, interactive web contents.

The Term AJAX originally coined by Jesse James Garrett of Adaptive Path in his

essay AJAX: A New Approach To Web Applications.

AJAX : Asynchronous JavaScript And XML

It's bit of mouthful, but it's simply describing a technic that uses JAVASCRIPT to refresh a page's content from a 

web server without having to reload the entire page. This is different from the traditional method of updating web pages, which requires the browser to refresh the entire page in order to display any changes to the content.

Some high profile examples such as. Google Maps , GMAIL , Backpack , Flicker  have allowed these kinds of highly interactive web applications to begin to gain traction in the development world.

This is just about the AJAX.
