标签: javascript jquery

我正在使用datatable来获取表值。但我无法获得任何数据,甚至表格长度。不知道我错过了什么。请有人帮我这个,



$(document).ready(function() {
  var table = $('#myTable').DataTable();
  var data = table.rows().data();
  alert("2");
  alert('The table has ' + data.length + ' records');
});

<script type="text/javascript" charset="utf8" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.7.1.min.js"></script>
<script type="text/javascript" charset="utf8" src="http://ajax.aspnetcdn.com/ajax/jquery.dataTables/1.9.0/jquery.dataTables.min.js"></script>

<table id="myTable" class="display" cellspacing="0" width="100%">
  <tbody>
    <tr>
      <td>Tiger Nixon</td>
      <td>System Architect</td>
      <td>Edinburgh</td>
      <td>61</td>
      <td>$320,800</td>
    </tr>
    <tr>
      <td>Cedric Kelly</td>
      <td>Senior Javascript Developer</td>
      <td>Edinburgh</td>
      <td>22</td>
      <td>$433,060</td>
    </tr>
  </tbody>
</table>

试试这个:

  var table = $('#example').DataTable();
 var data = table.rows().data();

  alert('The table has ' + data.length + ' records');
  $('td').click( function() {
    
    console.log(this);
    
    row_index = table.fnGetPosition(this)[0];
    
    console.log(row_index);
    
  });

数据表不是JQuery的内置属性。你必须使用外部插件吗?你收到了吗? 链接https://datatables.net

答案 2 :(得分:0)

Datable需要thead和tbody正常工作(你提到它在你的代码中但不在你的代码片段中)你还需要最小的css。您的问题似乎是您使用的版本。更新到lastr(参见片段)
