在javascript，jquery中滚动的上一个和下一个按钮

Question

我在网站上有一个部分，我需要显示facebook Feed。 我有两个按钮，如图所示。使用按钮我需要在新闻源之间“滚动”。

我应该用javascript或jquery来做这件事，但我对这些编程语言并不陌生。

.content .tab-pane > #facebook_ticker > li{
	max-height: 165px;
	min-height:165px;
}
.content .second-row .tab-content  .ticker-controls,
.single .content  .tab-content  .ticker-controls{
	background:rgba(0,0,0,.7);
	height: 35px;
	padding: 5px 20px;
	margin-top: -10px;
	font-family: 'TGLTCER';
	font-size: 1.2em;
}

<div class="hidden-xs">
                <h1 id="tgb_head"><span id="facebook_icon" class="social-content-icon"></span> Facebook</h1>
                    
    <div class="tab-content">
      <div class="tab-pane active fade in">
         <ul class="list-unstyled" id="facebook_ticker">
             <?php echo do_shortcode("[custom-facebook-feed]"); ?> 
          </ul>
       </div>
     <div id="facebook_ticker_controls" class="ticker-controls">
    <a href="#" class="prev pull-left test" id="fprev"><span class="glyphicon glyphicon-chevron-down"></span>&nbsp; Previous</a> 
    <a href="#" class="next pull-right test" id="fnext">Next &nbsp;<span class="glyphicon glyphicon-chevron-up"></span></a> 
   </div>
                      
 </div><!-- end tab-content -->
                    
 </div><!-- end facebook -->
            
            
 <!-- The  ?php echo do_shortcode("[custom-facebook-feed]"); ? generates the following code--> 
                
                
 <div class="cff-wrapper">
   <div id="cff" data-char="400" class="cff-width-resp cff-default-styles" style="padding:5%; ">

   </div>

我尝试过这样的事情：

  <script>
  $('#facebook_ticker_controls a.prev').click(function() {
  $.scrollTo($(this).closest('cff-item').prev(),800);
  });

  $('#facebook_ticker_controls a.next').click(function() {
  $.scrollTo($(this).closest('cff-item').next(),800);
  }); 
  </script>

但它什么也没做。你可以给我一个提示，试着解决这个问题吗？感谢
