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.

![Regular Expressions for the Rest of Us]()
Sooner or later you'll run across a regular expression. With their cryptic syntax, confusing documentation and massive learning curve, most developers settle for copying and pasting them from StackOverflow and hoping they work. But what if you could decode regular expressions and harness their power? In...
![jQuery Link Nudge Plugin]()
A while back I debuted a tasteful mouseover/mouseout technique called link nudging. It started with a MooTools version and shortly thereafter a jQuery version. Just recently Drew Douglass premiered a jQuery plugin that aimed at producing the same type of effect.

Morphing an element between CSS classes is another great trick the MooTools JavaScript library enables you to do. Morphing isn't the most practical use of MooTools, but it's still a trick at your disposal.

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
