Updated Demo : 任何幫助非常感謝！我有一個需要計數器滑塊的jQuery旋轉木馬/滑塊

我已.. 這裏的demo

DEMO with disabled Arrow keys

JS：

$(document).ready(function(){ 
     $("#featured").tabs({fx:{opacity: "toggle", duration: "fast"}}); 

     var sliderNavLength = $('.ui-tabs-nav li').length; 
     var sliderNavUlHeight = $(".ui-tabs-nav")[0].scrollHeight; 

     var sliderNavLiHeight = 0; 

     $(".ui-tabs-nav li:lt(3)").each(function() { 
      sliderNavLiHeight += $(this).height(); 
     }); 
     var recCount = 3; 

     $('.ui-tabs-nav li:first-child()').addClass('firstChild'); 
     $('.ui-tabs-nav li:last-child()').addClass('lastChild'); 

     $('.slide-counter').find('.s-counter').text(" of " + sliderNavLength);  

     $('.up-arrow').click(function(e){    

      if (recCount > 3) { 

       var sliderScrollCountMinus = $('.ui-tabs-nav').scrollTop() - sliderNavLiHeight; 
       $('.ui-tabs-nav').animate({ scrollTop: sliderScrollCountMinus }, 1000); 
       $('.counter').val(parseInt($('.counter').val()) - 3); 
       $('.counterSingle').val(parseInt($('.counterSingle').val()) - 3); 

       recCount = recCount - 3; 
      } 

     }); 

     $('.down-arrow').click(function(e){
