Can anyone please tell about how to apply group name to html (input) radio button controls so that i can select any one of the available radio buttons?
谁能告诉我如何将组名应用于 html（输入）单选按钮控件，以便我可以选择任何一个可用的单选按钮？
I have input radios in a table. Each row contains two radios as follows. I want to select one from each row. But i am able to select only one radio button amongst all radio buttons present on all rows.
我在表格中输入了收音机。每行包含两个无线电，如下所示。我想从每一行中选择一个。但是我只能在所有行上的所有单选按钮中选择一个单选按钮。
<input name="radiobutton" type="radio" value="radiobutton" />Option1
<input name="radiobutton" type="radio" value="radiobutton" />Option2

As far as I know, radiobuttons in HTML do not have group names. Their HTML "name" attribute isthe group name.
据我所知，HTML 中的单选按钮没有组名。它们的 HTML“名称”属性是组名称。
It is important to verify that each radiobutton has a unique "value" attribute. Otherwise there is no way to tell which of the duplicate values was selected:
验证每个单选按钮是否具有唯一的“值”属性很重要。否则无法判断选择了哪个重复值：
<input name="radiobutton" type="radio" value="radiobutton1" />Option1
<input name="radiobutton" type="radio" value="radiobutton2" />Option2

This example lets you choose only one radio button per table row. You have to give all radio buttons the same Name= to create a mutually exclusive group of them.
此示例允许您在每个表格行中仅选择一个单选按钮。您必须为所有单选按钮提供相同的 Name= 以创建它们的互斥组。
<form>
<table>
<tr><td>
<!-- Can choose only one of these two. -->
<input name="group1" type="radio" value="1a" />Option1
<input name="group1" type="radio" value="1b" />Option2
</td></tr>
<tr><td>
<!-- Can choose only one of these two. -->
<input name="group2" type="radio" value="2a" />Option1
<input name="group2" type="radio" value="2b" />Option2
</td></tr>
</table>
</form>
