How to: detect a click outside an element with jQuery

Attach a click event to the document body which closes the window. Attach a separate click event to the window which stops propagation to the document body.

$('html').click(function() {
//Hide the menus if visible
});

$('#menucontainer').click(function(event){
    event.stopPropagation();
});

Warning, if using this technique, be aware of the dangers of stopping propagation.
