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.

Introduction
For quite a long time now websites with the so called "parallax" effect have been really popular.
In case you have not heard of this effect, it basically includes different layers of images that are moving in different directions or with different speed. This leads to a...
![Page Visibility API]()
One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?
![Xbox Live Gamer API]()
My sharpshooter status aside, I've always been surprised upset that Microsoft has never provided an API for the vast amount of information about users, the games they play, and statistics within the games. Namely, I'd like to publicly shame every n00b I've baptized with my...
![CSS Custom Cursors]()
Remember the Web 1.0 days where you had to customize your site in every way possible? You abused the scrollbars in Internet Explorer, of course, but the most popular external service I can remember was CometCursor. CometCursor let you create and use loads of custom cursors for...
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
