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--------------------
