        'OAnimation':'oAnimationEnd',
        'MSAnimation':'MSAnimationEnd',
        'WebkitAnimation':'webkitAnimationEnd'

    for(var t in transitions){
        if( transitions.hasOwnProperty(t) && el.style[t] !== undefined ){
            return transitions[t];
        }
    }
}

$("#elementToListenTo")
    .on(whichTransitionEvent(),
        function(e){
            console.log('Transition complete!  This is the callback!');
            $(this).off(e);
        });
