推荐答案

您需要使用name属性将它们连接在一起，使用value属性为它们赋予不同的值。

You need to use the "name" attribute to tie them all together, use the value attribute to give them different values.

<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 />

想想姓氏......举个例子，如果你有Bart，Lisa，Homer， Marge和Maggie，这个名字将是他们的姓氏：Simpson，其价值将会是上述名字：

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:

<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 />
