About jQuery and AJAX

jQuery provides several AJAX-related methods.

With the jQuery AJAX method, you can use HTTP Get and HTTP Post to request text, HTML, XML, or JSON from a remote server - and you can load this external data directly into the selected elements of the Web page.

	Without jQuery, AJAX programming is still a bit difficult. Writing regular AJAX code is not easy because different browsers implement AJAX differently. T his means that you must write additional code to test the browser. However, the jQuery team solved this problem for us, and we only needed a simple line of code to implement AJAX functionality.

Tip: For more information about HTTP Get and HTTP Post, please refer to the "HTTP Method: GET Vs POST" section of this site!
