function getRadioGroupValue(radioGroupObj)
{
for (var i=0; i < radioGroupObj.length; i++)
if (radioGroupObj[i].checked) return radioGroupObj[i].value;

return null;
}

Использовать так: var v = getRadioGroupValue(document.formName.radioName);

В вашем конкретном случае использовать так:
var v = getRadioGroupValue(f2.r1);
