Basic Requirement for AJAX Learning

In previous part of AJAX tutorial we went through What is AJAX? Different types of online web applications which are using AJAX, We discuss in depth the concept behind AJAX, Characteristics of AJAX applications and also covered those characteristic which AJAX doesn’t cover. Now we are going ahead in more practical life of AJAX:

 
Basic Requirement for AJAX Learning

Before you continue you should have a basic understanding of the following:

* HTML / XHTML
* JavaScript

As we already know that AJAX stands for Asynchronous JavaScript and XML. AJAX is not a new programming language, but a technique for creating better, faster, and more interactive web applications.

With AJAX, your JavaScript can communicate directly with the server, using the JavaScript XMLHttpRequest object. With this object, your JavaScript can trade data with a web server, without reloading the page.

AJAX uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages. The AJAX technique makes Internet applications smaller, faster and more user-friendly. You can say AJAX is a browser technology independent of web server software.

 
Web Standards Behind AJAX

AJAX is based on the following web standards:

* JavaScript
* XML
* HTML
* CSS

The web standards used in AJAX are well defined, and supported by all major browsers. AJAX applications are browser and platform independent.

 
Benifits of AJAX Applications

Web applications have many benefits over desktop applications; they can reach a larger audience, they are easier to install and support, and easier to develop. However, Internet applications are not always as “rich” and user-friendly as traditional desktop applications. With AJAX, Internet applications can be made richer and more user-friendly.

Infact you don’t need to learn anything to use AJAX in your websites, blogs etc.. AJAX is based on existing standards. These standards have been using for last so many years. And If you already know them them you can take off otherwise there are few things which you have to learn but don’t worry it’s all about spoon feeding in HeyGB.com
