Q:

How to get radio button to display alert message

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>

How would I get so when any of these radio buttons are selected an alert is displayed to the user saying: "Are you sure you have chosen the correct entry level?"
Please keep answers simple, as I have only been learning HTML for 3 weeks

A:

You can do:
<input type="radio" name="level" id="GCSE" value="GCSE" onclick="alert('test');" />

Good luck!
