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.

One of my favorite social APIs was the Open Graph API adopted by Facebook. Adding just a few META tags to each page allowed links to my article to be styled and presented the way I wanted them to, giving me a bit of control...

CSS and JavaScript: the lines seemingly get blurred by each browser release. They have always done a very different job but in the end they are both front-end technologies so they need do need to work closely. We have our .js files and our .css, but...

CSS cubes really showcase what CSS has become over the years, evolving from simple color and dimension directives to a language capable of creating deep, creative visuals. Add animation and you've got something really neat. Unfortunately each CSS cube tutorial I've read is a bit...

In case you weren't aware, CSS animations are awesome. They're smooth, less taxing than JavaScript, and are the future of node animation within browsers. Dojo's mobile solution, dojox.mobile, uses CSS animations instead of JavaScript to lighten the application's JavaScript footprint. One of my favorite effects...
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
