问题描述

我想要一个单选按钮，当它被选择时显示一个警报，这样用户就可以检查他们是否选择了正确的值.这是我的单选按钮代码:

I want to get a radio button to display an alert when it is selcted, so the user can check that they have chosen the correct value. This is the code I have for the radio buttons:

 <tr>
     <td><input type="radio" name="level" id="GCSE" value="GCSE">GCSE<br>
    <input type="radio" name="level" id="AS" value="AS">AS<br>
    <input type="radio" name="level" id="A2" value="A2">A2</td>
 </tr>
