Try this function:
$('body,html').bind('scroll mousedown wheel DOMMouseScroll mousewheel keyup', function(e){
if ( e.which > 0 || e.type == "mousedown" || e.type == "mousewheel"){
$("html,body").stop();
}
})
Also, did you see this tutorial?
Update: Modern browsers now use “wheel” as the event, so I’ve included it in the code above.
