SitePen: Creating and Enhancing Dojo Classes
Written by David Walsh on July 1, 2010 · 1 Comment
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.

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
