jQuery单击功能,等待它再次启动之前完成？

当我加倍/高音/等单击.next按钮时脚本运行,我需要它在队列之后排队吗？我怎么能这样做才能在重新开始之前完成功能？

<ul id="one" class="first SELEcted">
   <li class="pic_one"></li>
   <li class="pic_two"></li>
   <li class="pic_three"></li>                       
</ul>
<ul id="two">
   <li class="pic_one"></li>
   <li class="pic_two"></li>
   <li class="pic_three"></li>                        
</ul>
<ul id="three" class="last">
   <li class="pic_one"></li>
   <li class="pic_two"></li>
   <li class="pic_three"></li>                        
</ul>

jQuery的

$('.slider .next').click(function(){
   if($('.slider ul.SELEcted').hasClass('last')){
      // leave blank
   } else {
      $('.slider ul.SELEcted').hide('slide',{ direction: "left" },1000);  
      $('.slider ul.SELEcted').removeClass('SELEcted');
      $('.slider ul').parent().next('ul').show('slide',{ direction: "right" },1000).addClass('SELEcted'); 
   }
});

$('.slider .next').click(function(){
   if($('.slider ul.SELEcted').is(':animated')) return;

   if($('.slider ul.SELEcted').hasClass('last')){
      // leave blank
   } else {
      $('.slider ul.SELEcted').hide('slide',1000).addClass('SELEcted'); 
   }
});
