This article gives you details about learning the Ajax frameworks. Ajax Frameworks is used to develop the responsive UI for the web applications.
'Asynchronously' refers to operating from the background. Ajax appeared in the market on February 18, 2005 after being created by Jesse James Garrett. Asynchronous Java script and XML, abbreviated as 'Ajax', is a group of web development techniques that operate web technologies on the client-side. Client-side connotes to operations carried out by the client in a client-server relationship in a network.
In techniques like Ajax, data can be sent and received in web applications without any intrusion into the display and behavior of the page that is existent then. You need to keep this important introductory information in mind when you are learning what Ajax is all about. The data interchange layer is decoupled from the presentation layer and web pages and web applications do not require reloading the entire page. The content is dynamically altered.
As Ajax is a group of technologies you need to approach it in a newer, more organized manner. The benefits that Ajax provides are great and the technologies involved are: HTML (or XHTML) and CSS for presentation, the Document Object Model aimed at dynamic display of and intercommunication with data, the XMLHttpRequest object for asynchronous communication and JavaScript to assimilate all the technologies together. So, you need to keep web applications and related topics in mind when you are learning Ajax. That will help you in the long run, too.
You should also consider the fact that certain browsers that do not support JavaScript or XMLHttpRequest will not be able to use pages that depend on Ajax. You need to learn that have been many transformations in the development of this web development techniques. Ajax is a developer's dream. You need to be well-equipped with a fairly good knowledge of web technologies. Only then can Ajax benefit you.

Google Maps uses Ajax. A prime feature is evident when the interface enables the user to change views and manoeuvre the map in real time. Ajax applications operate with a Web browser. Earlier versions used to operate only on Microsoft's Internet Explorer browser as the technique was solely dependent on XMLHttpRequest. But, nowadays, other browsers support it, too. A usage of an engine is frequent now. This engine connects the browser and the server and from which information is being requested. These are the common features of Ajax and they will help you to get acquainted with this method of building applications before you throw yourself headlong into learning and practicing this group of technologies.
You can read the books 'A Brief History of Ajax' to get yourself acquainted with this development technique, book excerpts like 'Using the Ajax.NET Pro Library' and 'Ajax and the dynamic double combo', 'Introduction to ASP. NET Ajax Controls' and chapters in books like 'Ajax Security - chapter 6' (Transparency in Ajax Applications).
The 'Mozilla Ajax getting started guide' teaches you the fundamentals of how to make a HTTP request, how to handle the server response, etc. Before venturing out in this domain do keep yourself informed about 10 things you need to know about Ajax which you might come across in 'Network World'.
