Ajax makes it possible for web developers to build and design modern web applications that work on most modern browsers. Building websites with PHP and AJAX technologies is a stable, reliable and professional approach used in modern website design and programming.
Ajax Web Applications
Google Maps is the best-known Ajax application that refreshes almost before your eyes when you use it. There is very little lag and you don’t have to wait long for web application to reload. Besides mapping applications, examples of AJAX apps include e-mail apps, real-time searches, live shopping cart apps, online chats.
Developing web apps using Ajax programming:
In standard web apps, the interaction between the user and the server is synchronous and involves several processes which have to happen after the other and require a lot of user waiting. Firstly, the user accesses the web application. Then, the request is processed by the server that sends data to the browser while the user is waiting. The user again clicks around the application and the server again sends data back to the browser while the user is waiting. So, why use AJAX?
AJAX itself is not a technology. Ajax is a combination of web development technologies that work together to allow client-server interactions occur without requiring pages to reload. AJAX based web applications gain high levels of processing, accessibility and interactivity.
