This is an extension for Backbone.js with a Sync that adds support for IE 7-9 CORS requests using IE's XDomainRequest Object while maintaining compatibility with non-IE systems.
This is intended as a drop-in replacement for the default Backbone.sync so you should be able to just plop this in and Cross Domain Requests (using CORS) should just magically work on IE.
You can manually download/install this library or grab it with npm:
npm install backbone-crossdomain
Include Backbone.CrossDomain after including Backbone.js:
And that's it! Now anything that uses Backbone.sync() internally should work with a cross domain request from IE7/8/9 where they didn't previously. This means model.fetch(), model.save(), model.sync, collection.fetch(), etc.
Easy install with Bower.
bower install backbone.crossdomain
This library has AMD support for use with RequireJS. This is not necessary to use this library but helpful when building an app with AMD.
RequireJS config (with Backbone and Underscore using a shim):
Use Backbone as you would normally, this is a drop-in replacement and shouldn't require anything to change.
