Скрипт MouseWheel выдает ошибку в IE

Question

Хорошо, вот рабочий кросс-браузерный код, который хорошо работает:

function handle(delta) {
var time = 1500;
var easing = 'easeInOutExpo';
var distance = document.getElementById('Element').scrollHeight;

$('html, body').stop().animate({
    scrollTop: $(window).scrollTop() - (distance * delta)
}, time, easing );
}
/** Event handler for mouse wheel event.
*/
function wheel(event){
    var delta = 0;
    if (!event) /* For IE. */
            event = window.event;
    if (event.wheelDelta) { /* IE/Opera. */
            delta = event.wheelDelta/120;
    } else if (event.detail) { /** Mozilla case. */
            /** In Mozilla, sign of delta is different than in IE.
             * Also, delta is multiple of 3.
             */
            delta = -event.detail/3;
    }
    /** If delta is nonzero, handle it.
     * Basically, delta is now positive if wheel was scrolled up,
     * and negative, if wheel was scrolled down.
     */
    if (delta)
            handle(delta);
    /** Prevent default actions caused by mouse wheel.
     * That might be ugly, but we handle scrolls somehow
     * anyway, so don't bother here..
     */
    if (event.preventDefault)
            event.preventDefault();
event.returnValue = false;
}

/** Initialization code. 
* If you use your own event management code, change it as required.
*/
if (window.addEventListener)
    /** DOMMouseScroll is for mozilla. */
    window.addEventListener('DOMMouseScroll', wheel, false);
/** IE/Opera. */
window.onmousewheel = document.onmousewheel = wheel;

Чтобы получить расстояние, есть два варианта: 1. вручную, задав значение 2. автоматически через css, определив "Элемент"

Надеюсь, что помог.
