jQuery鼠标轮不再工作了

Question

目前最新的jQuery版本是2.0.2 当我下载jQuery.mousewheel 3.0.4时，它不再适用于jQuery库，因为公共访问不会公开handle。我应该如何修改它以使其工作？

鼠标滚轮钩子：

function handler(event) {
    var orgEvent = event || window.event, args = [].slice.call( arguments, 1 ), delta = 0, returnValue = true, deltaX = 0, deltaY = 0;
    event = $.event.fix(orgEvent);
    event.type = "mousewheel";

    // Old school scrollwheel delta
    if ( event.wheelDelta ) { delta = event.wheelDelta/120; }
    if ( event.detail     ) { delta = -event.detail/3; }

    // New school multidimensional scroll (touchpads) deltas
    deltaY = delta;

    // Gecko
    if ( orgEvent.axis !== undefined && orgEvent.axis === orgEvent.HORIZONTAL_AXIS ) {
        deltaY = 0;
        deltaX = -1*delta;
    }

    // Webkit
    if ( orgEvent.wheelDeltaY !== undefined ) { deltaY = orgEvent.wheelDeltaY/120; }
    if ( orgEvent.wheelDeltaX !== undefined ) { deltaX = -1*orgEvent.wheelDeltaX/120; }

    // Add event and delta to the front of the arguments
    args.unshift(event, delta, deltaX, deltaY);

    return $.event.handle.apply(this, args);
}

jQuery句柄实现

jQuery.each({
    mouseenter: "mouseover",
    mouseleave: "mouseout"
}, function (orig, fix) {
    jQuery.event.special[orig] = {
        delegateType: fix,
        bindType: fix,

        handle: function (event) {
            var ret,
                target = this,
                related = event.relatedTarget,
                handleObj = event.handleObj;

            // For mousenter/leave call the handler if related is outside the target.
            // NB: No relatedTarget if the mouse left/entered the browser window
            if (!related || (related !== target && !jQuery.contains(target, related))) {
                event.type = handleObj.origType;
                ret = handleObj.handler.apply(this, arguments);
                event.type = fix;
            }
            return ret;
        }
    };
});

或者我知道使用bind（'mousewheel'）可以达到同样的效果。但我不知道如何获得滚动上下事件属性。我该怎么做？
