推荐答案
用以下内容替换您的单选按钮代码，
Replace your radio button code with the following,
<input type="radio" name="presenceFor1" />为每一行指定唯一的名称，并为单选按钮的行中的每个td指定相同的名称。
阅读 W3C [ ^ ]更多想法。

Give unique name for each row, and same name for each td in row for radio buttons.
Read W3C[^] for more idea.

您可以简单地为相应的无线电组提供相同的名称，以达到以下目的：
You can simply give the same name to the respective radio groups to achieve this like:
<tr>
<td>1</td>
<td>
<input type="radio" name="rbtnAttendance1" />Present
<input type="radio" name="rbtnAttendance1" />Absent
</td>
</tr>
<tr>
<td>2</td>
<td>
<input type="radio" name="rbtnAttendance2" />Present
<input type="radio" name="rbtnAttendance2" />Absent
</td>
</tr>
这样你只能从同名的单选按钮中选择一个选项。
This way you can only select one option from the radio buttons with same name.
