第二种是用js写的

    var timer = null;
    var num=0;  

     $('.links-cont').hover(function(){
       //获取盒子高度
       var linksH = $('.links-cont').height();
       //获取logo高度
       var logosH = $('.links-cont .logo').height();

       if(logosH > linksH)
       {
         //滚动
                timer = setInterval(function(){  
                    num++;  
                    if(num==logosH){  
                        $('.links-cont .logo').css({'marginTop':'0px'});  
                        num=1;  
                    }  
                    $('.links-cont .logo').stop().animate({'marginTop':-num+'px'},20);  
                },20);
       }
     },function(){ clearInterval(timer);});
