他们都需要相同 name 属性。

单选按钮按名称分组属性。以下是一个例子：



The radio buttons are grouped by the name attribute. Here's an example:

<fieldset>
    <legend>Please select one of the following</legend>
    <input type="radio" name="action" id="track" value="track" /><label for="track">Track Submission</label><br />
    <input type="radio" name="action" id="event" value="event"  /><label for="event">Events and Artist booking</label><br />
    <input type="radio" name="action" id="message" value="message" /><label for="message">Message us</label><br />
</fieldset>
