Ajax Programming

Ajax (Asynchronous JavaScript and XML) is a browser-based technology for creating highly interactive Web applications by updating parts of a Web page with new data without reloading the whole page. There is no formal definition of Ajax, but using XMLHttpRequest/JavaScript has become the dominant Ajax technology. The course starts with an introduction to using XMLHttpRequest and a brief introduction to JavaScript fundamentals. It includes in-depth coverage of programming with Ajax to send/retrieve data to/from a server, updating a Web page with JavaScript, and using CSS to modify the look of a Web page. There is also detailed coverage of how to handle Ajax requests using Servlets/JSP and Java Web applications and how to use frameworks, both client side JavaScript and server side Java. This course is hands on with labs to reinforce all the important concepts. It will enable you to build working Ajax applications, and give you an understanding of the important concepts and technology in a very short time.
