title: Determine if no Radio Button is Checked
body: <p>A large group of radio buttons exist on a form. They are not inside a panel, but for this example they are the only set of radios on the form.</p>
  
  <p>At initialization, <strong>no</strong> button will be selected.  (Likely, this is  not proper implementation of radios, but it's outside of my control; Suffice to say, for this example, the form must start out with no radio button selected.)</p>
  
  <p>Currently I use a rather lengthy if-else statement to check each button one at a time, but I feel there must be a simpler way to determine, right off the bat, if no button is checked. Besides the buttons already work as a group, because by definition a maximum of 1 selection is forced throughout.</p>
  
  <p>What would be the best practice for detecting if <strong>no radio button</strong> has been selected?</p>
