title: Making this timer start with a button
body: <p>I found this neat countdown timer and I was curious if someone could help with a few changes to it. </p>
  
  <ol>
  <li>Start on the click of a button. </li>
  <li>Where would I place an AJAX call function to a PHP file for when the timer hits 0?</li>
  <li>Repeat when it is finished.</li>
  </ol>
  
  <p>The timer I found is here: <a href="http://jsfiddle.net/johnschult/gs3WY/" rel="nofollow">http://jsfiddle.net/johnschult/gs3WY/</a></p>
  
  <pre><code>var countdown = $("#countdown").countdown360({
  radius: 60,
  seconds: 20,
  label: ['sec', 'secs'],
  fontColor: '#FFFFFF',
  autostart: false,
  onComplete: function () {
    console.log('done');
  }
  });
  
  countdown.start();
  
  $('#countdown').click(function() {
    countdown.extendTimer(2);
  });
  </code></pre>
  
  <p>Thanks in advance for any help given. </p>
