            MainActivity.wifi.disconnect();
            MainActivity.wifi.enableNetwork(i.networkId, true);

这是一张3x3的桌子，里面有9个单选按钮。我想配置它以便我可以：

• 每行选择仅1 单选按钮或
• 每列选择仅1 单选按钮

这可能没有任何JavaScript吗？谢谢！

您可以使行/列中的输入（根据您的需要）具有相同的名称，以便只能检查其中一个。

每行一个

<table>
  <tr>
    <td><input type="radio" name="radio1"></td>
    <td><input type="radio" name="radio1"></td>
    <td><input type="radio" name="radio1"></td>
  </tr>
  <tr>
    <td><input type="radio" name="radio2"></td>
    <td><input type="radio" name="radio2"></td>
    <td><input type="radio" name="radio2"></td>
  </tr>
  <tr>
    <td><input type="radio" name="radio3"></td>
    <td><input type="radio" name="radio3"></td>
    <td><input type="radio" name="radio3"></td>
  </tr>
</table>

每列一个

<table>
  <tr>
    <td><input type="radio" name="radio1"></td>
    <td><input type="radio" name="radio2"></td>
    <td><input type="radio" name="radio3"></td>
  </tr>
  <tr>
    <td><input type="radio" name="radio1"></td>
    <td><input type="radio" name="radio2"></td>
    <td><input type="radio" name="radio3"></td>
  </tr>
  <tr>
    <td><input type="radio" name="radio1"></td>
    <td><input type="radio" name="radio2"></td>
    <td><input type="radio" name="radio3"></td>
  </tr>
</table>
