JSONP and Backbone.js

Question

I would like to use Backbone.js with a REST api I control. I was hoping to have the REST api and the Backbone scripts live on a different domain but unfortunately this will be blocked, as it is a cross domain request.

Does Backbone.js have an built in functionality to support JSONP requests? Or, alternatively, does anyone have any experience with manually adding JSONP support to Backbone.js sync system?

Answer 1

JSONP support for GET operations can be added via fetch's options.

In the same hash where you configure your success and error handlers, add an object like so:

{dataType: "jsonp"}

This will pass along the jsonp option to JQuery's ajax handler, and automagically, you'll have JSONP support for retrieving models / collections.
