整理文档，搜刮出一个jquery DataTable实现前后台动态分页，稍微整理精简一下做下分享。

html代码:

<body>
<div style="width:50%;height:500px;margin:150px auto ;background-color: #f4cccc">
<table id="example" class="display" cellspacing="0" width="100%">
  <thead>
  <tr>
    <th>Name</th>
    <th>Cellphone</th>
    <th>Position</th>
    <th>Company</th>
    <th>Salary</th>
  </tr>
  </thead>
  <tbody>

  </tbody>
</table>
</div>

<script type="text/javascript" src="//code.jquery.com/jquery-1.12.3.min.js"></script>
<script type="text/javascript" src=" //cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
<script type="text/javascript">
  $(document).ready(function() {
    refreshDataTable();
  });

 var refreshDataTable=function() {
   var table = $('#example').DataTable({
     //"ajax":"data/tabledata.json",
    // "iDisplayLength": 3,
     "sPaginationType": "full_numbers",
     "bPaginite": true,
     "bInfo": true,
     "bSort": true,
     "processing": false,
     "serverSide": true,
     "sAjaxSource": "customize/datatable.php",//这个是请求的地址
     "fnServerData": retrieveData

   });
   function retrieveData(url, aoData, fnCallback) {
     var data={"data":{"id":"123123","name":"2s",}};
     $.ajax({
       url: url,//这个就是请求地址对应sAjaxSource
       data : {
         "aoData" : JSON.stringify(aoData)
       },
       type: 'POST',
       dataType: 'json',
       async: false,
       success: function (result) {

         //var obj=JSON.parse(result);
         console.log(result);
         fnCallback(result);//把返回的数据传给这个方法就可以了,datatable会自动绑定数据的
       },
       error:function(XMLHttpRequest, textStatus, errorThrown) {

         alert("status:"+XMLHttpRequest.status+",readyState:"+XMLHttpRequest.readyState+",textStatus:"+textStatus);

       }
     });
   }
 };
</script>
</body>
</html>

PHP代码:

<?php
header('Content-type: text/json');
  $res = $_POST['aoData'];
 $sEcho = 0;
 $iDisplayStart = 0; // 起始索引
 $iDisplayLength = 0;//分页长度
 $jsonarray= json_decode($res) ;
  foreach($jsonarray as $value){ 
  if($value->name=="sEcho"){
    $sEcho=$value->value;
  }
  if($value->name=="iDisplayStart"){
    $iDisplayStart=$value->value;
  }
  if($value->name=="iDisplayLength"){
    $iDisplayLength=$value->value;
  }
  }  
  $Array = Array(); 
   //此处生成50条数据，模仿数据库数据
  for ($i = 1; $i < 51; $i++) {
    $d = array($i,$i,$i,$i,$i);
    Array_push($Array, $d);
  }

   $json_data = array ('sEcho'=>$sEcho,'iTotalRecords'=>50,'iTotalDisplayRecords'=>50,'aaData'=>array_slice($Array,$iDisplayStart,$iDisplayLength)); //按照datatable的当前页和每页长度返回json数据
  $obj=json_encode($json_data);
  echo $obj; 

?>
