Question

我正在尝试使用jquery数据表向tr添加行ID。我甚至试过这个例子 http://datatables.net/release-datatables/examples/server_side/ids.html但似乎没有用，我使用了相同的JSON文件。

非常感谢任何帮助。

应该提供类似

的内容

<tr id="row_7">
  <td>Emkay Entertainments</td>
  <td>Nobel House, Regent Centre</td>
  <td>Lothian</td>
</tr>
<tr id="row_8">
  <td>The Empire</td>
  <td>Milton Keynes Leisure Plaza</td>
  <td>Buckinghamshire</td>
</tr>

＆GT;更新的代码

<script type="text/javascript" charset="utf-8">
  $(document).ready(function () {
    var oTable = $('#example').dataTable(
      /** column structure and ppoluating columns **/ {
      "aoColumnDefs": [{
          "aTargets": [0],
          //"mData": "download_link",
          "mRender": function (data, type, full) {}
        }, {
          "aTargets": [1],
          //"mData": "download_link",
        }, {
          "aTargets": [2],
          //"mData": "download_link",
        }, {
          "aTargets": [3],
          //"mData": "download_link",
        }, {
          "aTargets": [4],
          //"mData": "download_link",
        }],
      "fnRowCallback": function(nRow, aData, iDisplayIndex) {
        nRow.setAttribute('id',some_variable);
      },
      "bFilter": false,
      "sScrollY": "300px",
      "bPaginate": false,
      "bProcessing": true,
      //"bServerSide": true,
      "sAjaxSource": "media/sample.json"
    }
  /*** End of column structure **/).makeEditable({
      sUpdateURL: "UpdateData.php",
      sAddURL: "AddData.php",
      sAddHttpMethod: "GET", //Used only on google.code live example because google.code server do not support POST request
      sDeleteURL: "DeleteData.php"
    });
  });
</script>

您可以将以下内容添加到dataTables初始化选项中：

"fnRowCallback": function(nRow, aData, iDisplayIndex) {
    nRow.setAttribute('id',some_variable);
}

要使用特定表格单元格的值作为每行的ID，请从aData变量中提取它：

"fnRowCallback": function(nRow, aData, iDisplayIndex) {
    nRow.setAttribute('id',aData[0]);
}

如何为每行添加行ID？
