1HTML

         <ul id="toplist">
    {loop $list $row}


            <li >
                 <a onclick="view({$row['rid']},{$row['id']})">

                    <div style="width:25%;"><i class="two"><span class="pull-left pos">{php echo ++$pxid;}</span></i></div>
                    <div style="width:15%;">{$row['id']}</div>
                    <div style="width:45%;">{$row['nickname']}</div>

                    <div style="width:15%;">{$row['num']}</div>


                </a>
            </li>
   {/loop}     
        </ul>
       <div id="loadtop" ><i class="fa fa-spinner fa-spin"></i>正在加載更多</div> 

2.加載更多Js

<script src="http://cdn.bootcss.com/jquery/1.11.3/jquery.min.js"></script>
  <script type="text/javascript">
    var load_flag=false;
    var page={$page};
      $(function(){

        $(window).scroll(function(){

            if(load_flag){

                return;

            }

            var totalheight = parseFloat($(window).height()) + parseFloat($(window).scrollTop());

            if(totalheight>=$(document).height()){

                $("#loadtop").show();

                load_flag=true;

                loadTop();

            }

        });

    });

      function loadTop(){
               $.ajax({
             url:"{php echo $this->createMobileUrl('Index',array('op'=>'loadtop'))}",
            type:'post',
            data:"page="+page+"&id="+{$id},
            dataType:'json',
            success:function(data){
                 var html="";
                  if(data.length>=10){

                    load_flag=false;

                   }else{

                   load_flag=true;

                     $(window).scroll = null;

                  $("#loadtop").html("已加載完全部");

                    }
                for(var i=0;i<data.length;i++){
                  var item=data[i];
                   var tppp=page+i+1;
html+='<li><a  onclick="view('+item.rid+','+item.id+')"><div style="width:25%;"><i class="two"><span class="pull-left pos">'+tppp+'</span></i></div><div style="width:15%;">'+item.id+'</div><div style="width:45%;">'+item.nickname+'</div><div style="width:15%;">'+item.num+'</div></a></li>';

                }
              $("#toplist").append(html);
                  page=page+10;
          }
         });


      }

          function view(id,uid){


            location.href="{php echo $this->createMobileUrl('Index',array('op'=>'detail'))}&id="+id+"&uid="+uid;
          }

  </script>

3.PHP端處理代碼

if($op=='loadtop'){
      $id=$_GPC['id'];
       $activty=pdo_fetch("SELECT * FROM ".tablename('lb_vote')." WHERE   id=:id and  uniacid=:uniacid ", array(':uniacid'=>$_W['uniacid'],':id'=>$id));
      /*獲取活動設置默認首頁顯示幾個用戶*/
     $page=$_GPC['page']?intval($_GPC['page']):0;
     $list=pdo_fetchall("SELECT * FROM ".tablename('lb_vote_info')." WHERE   rid=:rid and  uniacid=:uniacid and  pass=:pass order by num desc limit ".$page.",10", array(':uniacid'=>$_W['uniacid'],':rid'=>$id,':pass'=>1));
    echo json_encode($list);
}
