Question : Loop through radio buttons using javascript

I have a form that contains a bunch of radio buttons - that is built dynamically from my DB.

How can I read through the radio buttons named apradio to determine which one was selected?

The HTML code for the radio button is:
<input type='radio' name='apradio' id='apradio' value='1'>
<input type='radio' name='apradio' id='apradio' value='2'>
Etc.

Thanks...
