title: Jquery: Uncheck a radiobutton (in a group of 1 radiobutton)
body: <p>I have this code to uncheck a group of radiobuttons:</p>
  
  <pre><code>$('form[id^="fm-form"]')
       .find("input.groupOfButtons:radio:checked")
       .prop('checked',false);
  </code></pre>
  
  <p>This works fine when there are at least two radiobuttons in the group. </p>
  
  <p>If there is only one, the script doesn't work. </p>
  
  <p>How can I disable a radiobutton when there is only 1 radiobutton?</p>
