                }else{

            _this.hover(function(){
                clearInterval(intId[i]);
            },function(){
                intId[i] = setInterval(function(){
                    if(_this.find("ul").height()<=_this.height()){
                        clearInterval(intId[i]);
                    }else{
                        marquee(_this, sh);
                    }
                }, speed);
            });

        });

    }

})(jQuery);


然后只需写个向上滚动的js

 $("#person").myScroll({
                speed:40,//数值越大,速度越慢
                rowHeight:20//li的高度
            })

这样就ok了

html:

<div cllass="person">
<ul>
<li>1111</li>
<li>2222</li>
<li>3333</li>
<li>4444</li>
<li>5555</li>
</ul>
</div>
