Angular Bookmarklet for Chrome

AngularBookmarklet.js

javascript:
var angularVersion = "1.2.23";
if (typeof(angular) == "undefined") {
	var angularScript = document.createElement('script');
	angularScript.type = "text/javascript";
	angularScript.src = "//ajax.googleapis.com/ajax/libs/angularjs/" + angularVersion + "/angular.min.js";
	angularScript.onload = function() {
		console.log("AngularJS " + angular.version.full + " loaded successfully.");
	};
	angularScript.onerror = function() {
		delete angular;
		console.error("Error while loading AngularJS!");
	};
	document.getElementsByTagName('head')[0].appendChild(angularScript);
} else {
	if (typeof(angular) == "object") {
		console.info("AngularJS (" + angular.version.full + ") is already loaded!");
	} else {
		console.info("AngularJS is already loading...");
	}
}

Here are the steps to create this bookmarklet in Chrome:

1. Open source code in raw mode
2. If bookmark bar isn't shown then show it with Shift + Cmd + b / Shift + Ctrl + b
3. Select all the source code with Cmd + a / Ctrl + a
4. Drag & Drop the selected source code to the bookmark bar
5. Right click on the new icon, select Edit ... and give it a name like Angular 1.2.23

Ready. Just open the javascript console with Alt + Cmd + j / Alt + Ctrl + j, click on the bookmarklet and have fun (i.e. angular.bootstrap(document);). ;-)
