title: Radio buttons not checked in jQuery
body: <p>I have this line of code for page load:</p>
  
  <pre><code>if ($("input").is(':checked')) {
  </code></pre>
  
  <p>and it works fine when the radio button input is checked.  However, I want the opposite.  Something along the lines of </p>
  
  <pre><code>if ($("input").not(.is(':checked'))) {
  </code></pre>
  
  <p>so that my if statement runs when none of the radiobuttons are selected.  What is the best way to go about this?</p>
