How can I determine the direction of a jQuery scroll event?

Question

I\'m looking for something to this effect:

$(window).scroll(function(event){
   if (/* magic code*/ ){
       // upscroll code
   } else {
      // downscrol

You can use both scroll and mousewheel option to track up and down movement at once.

 $('body').bind('scroll mousewheel', function(event) {

if (event.originalEvent.wheelDelta >= 0) {
      console.log('moving down');   
    }
    else {
      console.log('moving up'); 
    }
});

You can replace 'body' with (window) as well.
