Using Dojo and JSON to Build Ajax Applications

Overview

Ajax in the simplest sense is taken to mean the process of exchanging data between a web server and a web browser using JavaScript on a loaded web page. In the practical sense, it means avoiding browser requests in favor of asynchronous JavaScript processing, thus making the request/response process transparent to the user. To accomplish this, one can either write his own verbose JavaScript code or use already tested and functional libraries such as Dojo. This paper shows how to build Ajax-enabled applications using Dojo and JSON - two very different but complementary technologies that can significantly enhance the interface and usability of web applications.
