Permission denied to call method XMLHttpRequest.open

Asked by acrxx in JavaScript

Tags: JavaScript, As many as possible, uncaught exception: Permission denied to call method XMLHttpRequest.open

Hi Everyone,

I am a bit new to AJAX, but thought I'd have a go at creating a page which will load other pages into itself, but only if the URL is available. I seem to be getting the famous "uncaught exception: Permission denied to call method XMLHttpRequest.open" in FF, even though I am not accessing the page locally and I have included netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead") which is supposed to remedy the problem.

The other annoyance I am getting is that in IE it will not allow the content to load without clicking on a button to allow to load it. This not acceptable. Any ideas on how to get round this one as well?

Any help would be greatly appreciated,
