我有一张桌子:
<table>
<thead>
<tr>
<td>some1</td>
......
<td>some2</td>
<th>count</th>
<th>EditCount</th>
</tr>
</thead>
<tbody>
<tr>
<td>some1</td>
......
<td>some2</td>
<td>25</td>
<td><input type='text' value='1'/></td>
</tr>
<tr>
<td>some1</td>
......
<td>some2</td>
<td>35</td>
<td><input type='text' value='3'/></td>
</tr>
如何从每一行的输入中获取左侧的 td 值,例如当用户单击此输入时?
