Backbone.js model calling jsonp

JsonPExampleinBackbone.js

// backbone.js continues to impress, I needed to get data from a jsonp api
// I really wanted to do this the "right" backbone.js way and create a model and call fetch. 
// But the default backbone synch is not jsonp
// Turns out you can override a synch on a per model basis (thanks stackoverflow)
// whats nice is backbone.js continue to work as expected with the override

// here's a snippet (some changes to protect our privacy). An improvement could be to create a jsonp model class which MyModel inherits 
// the synch function is most important below, that's what tells backbone it's jsonp

MyModel = Backbone.Model.extend({
	url: function() { 
		return '/yourJsonpUrlhere';
	},
		
	// override backbone synch to force a jsonp call
	sync: function(method, model, options) {
		// Default JSON-request options.
		var params = _.extend({
		  type:         'GET',
		  dataType:     'jsonp',
		  url:			model.url()+"?callback=?",
		  processData:  false
		}, options);

		// Make the request.
		return $.ajax(params);
	},
	
	parse: function(response) {
		// parse can be invoked for fetch and save, in case of save it can be undefined so check before using 
		if (response) {
			if (response.success ) {
                                // here you write code to parse the model data returned and return it as a js object 
                                // of attributeName: attributeValue
                                
				return {name: response.name};      // just an example,                
			} 
		}
	}
