Igor Kusakov joined the IT world as a professional ten years ago, and has been involved in developing Web and distributed applications since the late nineties. Igor is currently a consultant and leads Ajax Dojo-based application development at IBM Rational. Igor's primary professional interests are Java development, Web project architectures, rich JavaScript-based browser clients, modern persistence frameworks, and tooling for efficient development. Along with having a bachelors degree in computer science, Igor is certified in Java, C++, and C programming.

Summary: 

In this in-depth introductory tutorial by Web application developer Igor Kusakov, you learn the basics of developing HTML widgets using Dojo; including how to refer an image, how to add an event handler to an HTML page, and how to handle composite widgets. Also, discover some important differences between plain old JavaScript-style coding versus using Dojo, and get tips for handling complex issues inherent in Web application development.

Note that this tutorial does not address the overall architecture of a Dojo application or the various Dojo packages. Since the Dojo toolkit is rapidly evolving, many issues discussed in the tutorial are subject to change.

Before you start

Learn what to expect from this tutorial and how to get the most out of it.

About this tutorial

The goal of this tutorial is to get you started with HTML widget development using the Dojo toolkit. You'll learn how to develop Dojo HTML widgets, starting with one that is very simple and working up to one that is more complex. By the end of the tutorial you will have experience with composite widgets and various event-handling alternatives.

This tutorial is intended to be technical, sober, and unbiased. It will be most useful to working developers who need to get their job done.
