jQuery - AJAX Introduction

AJAX is the art of exchanging data on a server, and updating parts of a web page - without reloading the entire page.

What is AJAX?

AJAX = Asynchronous JavaScript and XML

In short; AJAX is all about uploading data in the background and displaying it on a web page, without having to reload the entire page.

Examples of applications that use AJAX: Gmail, Google Maps, Youtube, and Facebook tabs.

What About jQuery and AJAX?

JQuery offers a few ways to work with AJAX.

With jQuery AJAX methods, you can request text, HTML, XML, or JSON to a remote server using both HTTP Get and HTTP Post - And you can upload external data directly to selected HTML elements of your webpage!

Without jQuery, AJAX coding can be a bit tricky!

Writing a standard AJAX code can be tricky, because different browsers have different syntax for AJAX implementation. This means you will need to write additional code to check different browsers. However, the jQuery team took care of this, so we could write AJAX performance in just one line of code.
