var pos = $div.scrollTop();
var nextPos = pos + (step * (-deltaY))
console.log("DelatY: " + deltaY + ", Step: " + step + ", nextPos: " + nextPos);
$div.scrollTop(nextPos);
}
bready(function() {
$('#test').bind('mousewheel', function (event, delta, deltaX, deltaY) {
if (delta > -2 && delta < 2) {
wheel($(this), deltaY);
event.preventDefault();
}
console.log(delta);
});
});
