Developing AJAX Applications (SS349)

OVERVIEW
The course enables existing developers to program using all the features of JavaScript, manipulate the DOM tree within an HTML document, validate information entered into HTML forms and send asynchronous requests to the server via XHR. There is a strong emphasis on writing maintainable, cross browser code and avoiding the common pitfalls associated with scripting languages in general and JavaScript in particular. By default the course uses FireFox (plus FireBug) and Chrome for all the examples and exercises.

WHO IS THIS COURSE SUITABLE FOR & PRE-REQUISITES
 Delegates should have 3 or more years programming experience in at least one of the following languages -Java, C#, C++, Perl, Python and Ruby.
