Cross-Domain AJAX for IE8 and IE9

Implements automatic Cross Origin Resource Sharing support using the XDomainRequest object for IE8 and IE9 when using the $.ajax function in jQuery 1.5+.

CORS requires the Access-Control-Allow-Origin header to be present in the AJAX response from the server.

In order to use XDomainRequest in Internet Explorer, the request must be:

• Only GET or POST
• When POSTing, the data will always be sent with a Content-Type of text/plain
• Only HTTP or HTTPS
• Protocol must be the same scheme as the calling page
• Always asynchronous

Working example here: http://jsfiddle.net/MoonScript/Q7bVG/show/

Instructions

With at least jQuery version 1.5, just include the jquery.xdomainrequest.min.js script into your page, then make your AJAX call like you normally would:

// GET
$.getJSON('http://jsonmoon.jsapp.us/').done(function(data) {
  console.log(data.name.first);
});

// POST
$.ajax({
  url: 'http://frozen-woodland-5503.herokuapp.com/cors.json',
  data: 'this is data being posted to the server',
  contentType: 'text/plain',
  type: 'POST',
  dataType: 'json'
}).done(function(data) {
  console.log(data.name.last);
});
