gistfile1.js

$(function() {
	var transitionEventsNames = 'transitionend webkitTransitionEnd oTransitionEnd MSTransitionEnd',
		fn = function(e) {
			$(this).off(transitionEventsNames, fn);
			$(this).on(transitionEventsNames, fn);
			console.log('transition', e);
		};
	$('.foo').on(transitionEventsNames, fn);
});
