SitePen: Creating and Enhancing Dojo Classes
You have probably noted over the past few months that I've been working a lot with the Dojo Toolkit. SitePen has been kind enough to allow me to guest blog about a Dojo topic I find very interesting: creating and enhancing Dojo classes. From the post:
Like all top-notch JavaScript toolkits, Dojo tries to make its classes as flexible as possible, knowing that users of the toolkit may have different ideas about how a given class or class method should work. Luckily, Dojo provides you a number of methods by which you can subclass or modify existing classes. Let's examine a few ways you can make Dojo classes exactly the way you like.

![Create a CSS Flipping Animation]()
CSS animations are a lot of fun; the beauty of them is that through many simple properties, you can create anything from an elegant fade in to a WTF-Pixar-would-be-proud effect. One CSS effect somewhere in between is the CSS flip effect, whereby there's...
![Serving Fonts from CDN]()
For maximum performance, we all know we must put our assets on CDN (another domain). Along with those assets are custom web fonts. Unfortunately custom web fonts via CDN (or any cross-domain font request) don't work in Firefox or Internet Explorer (correctly so, by spec) though...
![Redacted Font]()
Back when I created client websites, one of the many things that frustrated me was the initial design handoff. It would always go like this:
Work hard to incorporate client's ideas, dream up awesome design.
Create said design, using Lorem Ipsum text
Send initial design concept to the client...
![Spatial Navigation]()
Spatial navigation is the ability to navigate to focusable elements based on their position in a given space. Spatial navigation is a must when your site or app must respond to arrow keys, a perfect example being a television with directional pad remote. Firefox OS TV apps are simply...
Hi,
Maybe you’ll be able to help me with understanding new way of class definition in new dojo. I’m using latest version of dojo. I try to define a few classes in separate files. Example (js/TwitterManager.js):
require([ "dojo/_base/declare", "dojo/request/script"], function( declare, script) { declare("TwitterManager", script, { // The default username username: "defaultUser", get: function() { script.get("http://search.twitter.com/search.json", { jsonp: "callback", query: {q: "#dojo"} }).then(function(response){ //we're only interested in response.results, so strip it off and return it return response.results; }); } });});Then I try to instantiate this class in main file (index.html):
require(["dojo/on", "dojo/dom", "dojo/query", "dojo/mouse", "dojo/domReady!"], function(on, dom, query, mouse) { var x = new TwitterManager(); var results = x.get(); });This code doesn’t work. But when I remove from class definition “request/script” module it works fine. I really need to use “script.get” method in this class. Of course all code might be put in index.html :) but I look for OOP approach in dojo 1.8.
Thanks
