Check if jQuery or mooTools are loaded

Question

In my project I am using jQuery in client side and mooTools in admin side. I would like to be able to write some part of code (google maps functions, etc) which will be common for both of that libraries.

Is it possible to check if jQuery or mooTools libraries are loaded and use proper behaviours ?

$(document).ready(function() {}); or window.addEvent('domready', function(){});

$('#id'); or $('id');

$('googleMapLocalize').addEvent('click', function(){}); or $('googleMapLocalize').bind('click', function(){});

What is the best way ?

Answer 1

Both are adding global varibles with its names:

MooTools and jQuery

So just check:

if(window.MooTools) or if(window.jQuery)
