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.

![CSS vs. JS Animation: Which is Faster?]()
How is it possible that JavaScript-based animation has secretly always been as fast — or faster — than CSS transitions? And, how is it possible that Adobe and Google consistently release media-rich mobile sites that rival the performance of native apps?
This article serves as a point-by-point...
![fetch API]()
One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
![Display Images as Grayscale with CSS Filters]()
CSS filters aren't yet widely supported but they are indeed impressive and a modern need for web imagery. CSS filters allow you to modify the display of images in a variety of ways, one of those ways being displaying images as grayscale.
Doing so requires the...
![Use Custom Missing Image Graphics Using MooTools]()
Missing images on your website can make you or your business look completely amateur.
Unfortunately sometimes an image gets deleted or corrupted without your knowledge.
You'd agree with me that IE's default "red x" icon looks awful, so why not use
your own missing image graphic?

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
