当我说缺少一部分时:

var w=1500;//this value is added by me, you should post the part that provides this variable's value.

if(w > 1300) {
    $('.scroll-pane').bind('mousewheel DOMMouseScroll MozMousePixelScroll', function(event, delta) {
        if(event.originalEvent.wheelDelta /120 > 0 ) {
            val =this.scrollRight + (delta *433 * 2 );
            jQuery(this).animate({
                  scrollRight: val
            }, 500,'easeOutSine');
            event.preventDefault();
            $(this).text('scrolling up !');
        }
        else {
            val = this.scrollLeft - (delta * 433 * 2 );
            jQuery(this).stop().animate({
                scrollLeft: val
            }, 500,'easeOutSine');
            event.preventDefault();
        }
        clearTimeout(scrollTimeout);
    });
} //this was missing in the original

最后一行是代码没问题的地方
