Blank jQuery Bookmarklet

blankjquerybookmarklet.js

(function(){
if(window.myBookmarklet!==undefined){myBookmarklet();}else{
	// the minimum version of jQuery we want
	var v = "1.71";

	// check prior inclusion and version
	if (window.jQuery === undefined || window.jQuery.fn.jquery < v) {
		var done = false;
		var script = document.createElement("script");
		script.src = "https://ajax.googleapis.com/ajax/libs/jquery/" + v + "/jquery.min.js";
		script.onload = script.onreadystatechange = function(){
			if (!done && (!this.readyState || this.readyState == "loaded" || this.readyState == "complete")) {
				done = true;
				initMyBookmarklet();
			}
		};
		document.getElementsByTagName("head")[0].appendChild(script);
	} else {
		initMyBookmarklet();
	}

	function initMyBookmarklet() {

			// your JavaScript code goes here!
		})();

Make sure to change "myBookmarklet" and "initMyBookmarklet" to something less predictable!
