I got the solution. Thanks James

JavaScript

function onZoom(e) {
        var delta = 0;
        if (e.originalEvent) {
            if (e.originalEvent.wheelDelta) e.delta = e.originalEvent.wheelDelta / -40;
            if (e.originalEvent.deltaY) e.delta = e.originalEvent.deltaY;
            if (e.originalEvent.detail) e.delta = e.originalEvent.detail;
        }
        delta = e.delta;
}
