This is a wrong idea IMHO.

A radio-group without any checked is strictly illegal and error-prone.

Better make a hidden radio-button that can be checked by javascript.
And no loop is needed.


<form>
<input type='radio' name='a' value='none' 
checked style='display:none;' id='aNone'>
<label><input type='radio' name='a' value='1'> 1</label><br>
<label><input type='radio' name='a' value='2'> 2</label><br>
<label><input type='radio' name='a' value='3'> 3</label><br>
</form>

<button onclick = "document.getElementById('aNone').checked = true;">
Uncheck
</button>
