Dealing with a cross domain issue (due to same origin policy within browsers) for a Quickbase client I started researching solutions used by others:
- Cross-Domain Communication with IFrames with good overview by Michael Mahemoff
- more iframe examples
- another iframe example by Eugene Gladyshev
- easyXDM – Javascript library using messaging by Øyvind Sean Kinsey with git and live examples
- xssinterface – javascript library using messaging as well
- HTML5 Cross-Window Messaging by John Resig
- jQuery postMessage: Cross-domain scripting plug-in by Ben Alman
- Backwards compatible window.postMessage() by Josh Fraser
- Dave’s Cross-Site Scripting Support by Dave Rudder
- Using Flash as a proxy workaround – FixHr
- AJAST – Cross domain calls using Script Injection by Umakant Patil
- XHR testing in IE
Lots of other sites out there mentioning issues, hacks, server side workarounds etc..
Like most things no magic bullet just need to see what works in your situation.
