21

1 <div class="paging">
2             <div id="dvPager" class="page fr clearfix" style="margin: 10px 0 15px;"></div>
3         </div>

 a{color:#000;text-decoration:none;}
  .clearfix:after {clear: both;content: ".";display: block;font-size: 0;height: 0;line-height: 0;visibility: hidden;}
  .fr{float:none;}
  .page a{padding:6px 12px;border:1px solid #ddd;float:left;margin-left:-1px;color:#006dae;text-align:center;}
  .page a:hover{background:#ddd;}
  .page a.current{background:#006dae;color:#fff;border:1px solid #006dae;cursor: default;}
  .page .first{margin-right:10px;}
  .pageinfo{margin-left:10px;padding:6px 12px;border:1px solid #ddd;float:left;color:#006dae;text-align:center;}

下面是调用示例 ↓

 1 function loadData(pageIndex,pageSize){
 2       $.ajax({
 3             contentType:"application/json;charset=utf-8", 
 4               url:'?pageNum='+pageIndex+'&pageSize='+pageSize,
 5               type:"POST",
 6               dataType:"json",
 7               success:function(result){
 8                 if(null != result){
 9                  
10                     )
11                     var beginIndex = (pageIndex - 1) * pageSize;
12                     var endIndex = pageIndex * pageSize - 1;
13                     var pageCount = parseInt((result.totalRecords / pageSize)) + (result.totalRecords % pageSize ? 1 : 0);
14                     $('#dvPager').html(pager(pageSize, pageIndex, pageCount, 'loadData'));
15117             }
18     });
19  } 

说明：

pager(pageSize, pageIndex, pageCount, 'XXX')该方法 最后传入的参数XXX 是调用js方法的名称
