Question

我正在使用jquery数据表，我想显示数据库中存在的数据。我使用了以下代码：

$(document).ready(function() {
var oTable = $('#example').dataTable( {
    "bProcessing": true,
    "sAjaxSource": "server.php",
    "aoColumns": [
        { "mData": "f_name" },
        { "mData": "l_name" },
        { "mData": "email" },
        { "mData": "active_date" }

    ]
   } );
 } );

但我收到json格式错误，说服务器的json数据无法通过。我想知道应该在sAjaxSource中传递哪个文件，以便显示来自数据库的数据？现在我传递的server.php包含我的数据库连接代码

帮助将不胜感激这是我的server.php文件..但是我收到了json格式错误。

这里是html：我只粘贴

 <table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
    <thead>
      <tr>
        <th>f_name</th>
        <th>l_name</th>
        <th>email</th>
    <th>active</th>
         <th>create_date</th>   

      </tr>
    </thead>
  <tfoot>
      <tr>
        <th>f_name</th>
        <th>l_name</th>
        <th>email</th>
    <th>active</th>
         <th>create_date</th>
      </tr>
    </tfoot>
  </table>

Answer 1

    $(document).ready(function() { 
      var oTable = $('#example').dataTable( { 
       "bProcessing": true, 
       "bServerSide": true, 
       "sAjaxSource": "server.php" 
     } ); 
   } );

你错过了"bServerSide": true。
