jQuery and AJAX
jQuery includes everything you need to send Asynchronous request back to the WEB Server. Programmers can generate a POST request or GET request and jQuery notifies you when the request is complete. With the jQuery programmers can send and receive XML data (the x in Ajax programming stands for XML, after all ). jQuery arrival consumes the data in HTML (Hyper Text Markup Language), text or JAVA Script Object Notation – JSON format.
jQuery makes Ajax easy. In fact, jQuery makes so many things easy it has changed the way of web developers to write script code.
