Backbone.CrossDomain

Overview

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.

Installation

You can manually download/install this library or grab it with npm:

npm install backbone-crossdomain

Usage

Include Backbone.CrossDomain after including Backbone.js:

<script type="text/javascript" src="backbone.js"></script>
<script type="text/javascript" src="Backbone.CrossDomain.js"></script>

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.

Bower

Easy install with Bower.

bower install backbone.crossdomain

RequireJS

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.

Include RequireJS:

<script type="text/javascript" src="lib/require.js"></script>

RequireJS config (with Backbone and Underscore using a shim):

require.config({
    paths: {
        jquery: "lib/jquery",
        underscore: "lib/underscore",
        backbone: "lib/backbone",
        crossdomain: "lib/Backbone.CrossDomain"
    },
    shim: {
        underscore: {
            exports: '_'
        },
        backbone: {
            deps: ['underscore', 'jquery'],
            exports: 'Backbone'
        }
    }
});

Require crossdomain:

require(["underscore", "backbone", "crossdomain"], function(_, Backbone) {
    // Define your models and collections as normal
});

Use Backbone as you would normally, this is a drop-in replacement and shouldn't require anything to change.
