inherited jsonp support for backbone

backbone-jsonp.js

// here is a simple example of overriding the base backbone collection class to enable default jsonp support
// i am using the github api as an example. you can obviously modify (or not) the url to suit your needs

var username = 'catshirt';

Backbone.Collection = Backbone.Collection.extend({
	sync: function(method, model, options) {
		options.dataType = 'jsonp';
		options.url = _.sprintf('https://api.github.com%s', this.url);
		return Backbone.sync(method, model, options);
	},
	parse: function(resp, xhr) {
		return resp.data;
	}
});

var News = Backbone.Collection.extend({
	url: _.sprintf('/users/%s/received_events/public', username)
});

(new News()).fetch({ success: function(news) {
	console.log(_.sprintf('%s\'s news', username), news);
}});
