php - 使用 jquery 数据表添加、更新和删除数据库记录

Question

我使用以下代码使用 jquery 数据表显示数据库中的数据

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

上面的代码显示表格中的数据

 <table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
    <thead>
      <tr>
        <th>first name</th>
        <th>last name</th>
        <th>email</th>


      </tr>
    </thead>

    <tfoot>
      <tr>
        <th>first name</th>
        <th>last name</th>
        <th>email</th>
      </tr>
    </tfoot>
  </table>

现在我想添加/更新和删除数据。我该怎么做？

我试过了

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

但是数据没有显示。我该怎么办？

编辑:

这是我使用的文件 server.php。 server.php 只是我给该文件指定的名称服务器.php

我建议在谷歌上搜索您的确切问题，然后将“jQuery Datatable”添加到搜索末尾。我已经使用这个插件很多次了，看来围绕这个插件的社区非常好。
