获取指定tr内的div的值

<tbody>
<tr class="datagrid-row" node-id="000000010" style="height: 25px; ">
<td class="datagrid-td-rownumber">
<div class="datagrid-cell-rownumber">1</div>
</td>
</tr>
<tr class="datagrid-row" node-id="000000012" style="height: 25px; ">
<td class="datagrid-td-rownumber">
<div class="datagrid-cell-rownumber">2</div>
</td>
</tr>
</tbody>
如上，根据node-id 取得指定div内的值，1和2 ；解决问题会有加分，谢谢
问题补充：
html代码不能改动

解决方案 »

  1.   

    JQ的写法
      var data = $("#node-id").find("div").html()
      

  2.   

    <table>
      <tbody>
        <tr class="datagrid-row" node-id="000000010" style="height: 25px; ">
          <td class="datagrid-td-rownumber"><div class="datagrid-cell-rownumber">1</div></td>
        </tr>
        <tr class="datagrid-row" node-id="000000012" style="height: 25px; ">
          <td class="datagrid-td-rownumber"><div class="datagrid-cell-rownumber">2</div></td>
        </tr>
      </tbody>
    </table>
    <script type="text/javascript">
    function getRowNumber(nodeID) {
    var obj = document.getElementsByTagName('table')[0].getElementsByTagName('tbody')[0].getElementsByTagName('tr');
    for (var i = 0; i < obj.length; i ++) if (obj[i].getAttribute('node-id') == nodeID) return obj[i].getElementsByTagName('div')[0].innerHTML;
    }
    alert(getRowNumber('000000010')); //1
    alert(getRowNumber('000000012')); //2
    </script>
