The tutorial has related information on how to make asynchronous requests with JavaScript and Ajax, informative material on Ajax – Try/Catch Blocks of Code, sending requests with XMLHttpRequest to allow user to make requests and receive responses, adding AJAX to a website, Form validation with AJAX/PHP/MySQL, Callbacks and Ajax where user sets the onreadystatechange property of the XMLHttpRequest object to the name of the function to run. Then, when the server has processed the request, it will automatically call that function,to build Ajax-enabled applications using Dojo and JSON, the two very different but complementary technologies that can significantly enhance the interface and usability of web applications and more reference tutorials.
