You need to use the "name" attribute to tie them all together, use the value attribute to give them different values.
您需要使用“名称”属性将它们联系在一起，使用 value 属性为它们提供不同的值。
<input type="radio" name="number" value="one" /> One<br />
<input type="radio" name="number" value="two" /> Two<br />
<input type="radio" name="number" value="three" /> Three<br />
Think of name as last name... For example, if you had Bart, Lisa, Homer, Marge and Maggie, the name would be their last name: Simpson, the value would be the said names:
将 name 视为姓氏...例如，如果您有 Bart、Lisa、Homer、Marge 和 Maggie，则名称将是他们的姓氏：Simpson，值将是上述姓名：
<input type="radio" name="Simpson" value="Bart" /> Bart<br />
<input type="radio" name="Simpson" value="Lisa" /> Lisa<br />
<input type="radio" name="Simpson" value="Marge" /> Marge<br />
<input type="radio" name="Simpson" value="Homer" /> Homer<br />
<input type="radio" name="Simpson" value="Maggie" /> Maggie<br />

Also the order of name/value pair matter's I guess.Name should appear before the order
我猜测名称/值对的顺序也很重要。名称应该出现在顺序之前

I know! Do like this:
我知道！这样做：
<label><input type="radio" name="a">1</label>
<label><input type="radio" name="a">2</label>
<label><input type="radio" name="a">3</label>
Give everything same value for 'name' attribute. You add the name for the radio buttons
为“名称”属性赋予所有相同的值。您为单选按钮添加名称
