Greasemonkey AJAX request from a different domain?
Greasemonkey (and Tampermonkey) has built-in support for cross-domain AJAX. Use the GM_xmlhttpRequest function.
Here's a complete userscript that illustrates the process:
// ==UserScript==// @name _Starter AJAX request in GM, TM, etc.// @match *://YOUR_SERVER.COM/YOUR_PATH/*// @grant GM_xmlhttpRequest// @connect targetdomain1.com// ==/UserScript==GM_xmlhttpRequest ( { method: 'GET', url: 'http://targetdomain1.com/some_page.htm', onload: function (responseDetails) { // DO ALL RESPONSE PROCESSING HERE... console.log ( "GM_xmlhttpRequest() response is:\n", responseDetails.responseText.substring (0, 80) + '...' ); }} );You should also get in the habit of using the @connect directive -- even though it's not strictly required for Greasemonkey on Firefox, yet.
