The official jQuery mousewheel plugin that adds cross-browser mouse wheel support to your web projects.

It has been used for many years in a wide variety of jQuery plugins, websites and web applications. 

How to use it:

// using bind
$('#demo').bind('mousewheel', function(event, delta, deltaX, deltaY) {
  console.log(delta, deltaX, deltaY);
});

// using the event helper
$('#demo').mousewheel(function(event, delta, deltaX, deltaY) {
    console.log(delta, deltaX, deltaY);
});
