5 Easy Tutorials for Advanced JavaScript using Dojo

I’ve been using Dojo a lot lately and have really gotten knee deep in development with it. Best of all, it is so easy to do so. The number one thing I’ve noticed is that the community is great–very approachable and they really know what they are talking about. These are true programmers who love what they do, and it shows in this toolkit.

The Dojo Campus provides a wealth of documentation, tutorials for all levels, Dojo Cookies (kind of like recipes), and demos of cool features.

Below are just a handful of tutorials that are available to beginners in Dojo that really help you get started.

3. Easily listen for events
   Custom events and Dom Events are all well and good for method-to-method functionality. It is a really common use case to connect some event happening to call another function, but when you get into really ambiguous, large applications, you need some mechanism to just say “hey, something has happened, act accordingly” … dojo.publish and dojo.subscribe provide just that mechanism.

5. Separating Content from Presentation
   One of the cool things about Dojo is the dojo.xhrGet() function. It’s powerful because it makes transparent the browser dependent transports that make AJAX possible. In this cookie, we’re going to explore a simple use case in Dojo to separate content from the presentation of a page.
