Question

I’m trying to perform an Ajax query from within a Greasemonkey script, but I’m stuck with not being able to load data from a remote URL. The script only seems to function if the page being viewed is the same domain as the Ajax call. Example:

// ==UserScript== // @name          Hello jQuery // @namespace     http://www.example.com/ // @description   jQuery test script // @include       * // @require       http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.js // ==/UserScript==  $(document).ready(function() {     $.get('http://www.google.com', function(data){         alert('Data Loaded: ' + data);     }); });  // EOF 

This user script works perfectly when visiting google.com, but it fails with no error or alert on any other domain. What is the solution?

Only GM_xmlhttpRequest can do cross-site access, not the normal XMLHttpRequest that jQuery uses.
