Injecting jQuery into a page fails when using Google AJAX Libraries API

I'd like to inject jQuery into a page using the Google AJAX Libraries API, I've come up with the following solution: **http://my-domain.com/inject-jquery.js:** ;((function(){ // Call this function once jQuery is available var func = function() { jQuery("body").prepend('
jQuery Rocks!
'); }; // Detect if page is already using jQuery if (!window.jQuery) { var done = false; var head = document.getElementsByTagName('head')[0]; var script = document.createElement("script"); script.src = "http://www.google.com/jsapi"; script.onload = script.onreadystatechange = function(){ // Once Google AJAX Libraries API is loaded ... if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) { done = true; // ... load jQuery ... window.google.load("jquery", "1", {callback:function(){ jQuery.noConflict(); // ... jQuery available, fire function. func(); }}); // Prevent IE memory leaking script.onload = script.onreadystatechange = null; head.removeChild(script); } } // Load Google AJAX Libraries API head.appendChild(script); // Page already using jQuery, fire function } else { func(); } })()); The script would then be included in a page on a separate domain: **http://some-other-domain.com/page.html:** This is my page

This is my page.

In Firefox 3 I get the following error: Module: 'jquery' must be loaded before DOM onLoad! jsapi (line 16) The error appears to be specific to the Google AJAX Libraries API, as I've seen others use a jQuery bookmarklet to inject jQuery into the current page. My question: * Is there a method for injecting the Google AJAX Libraries API / jQuery into a page regardless of the onload/onready state?
