title: Remove "autoplay" attribute from <video> element
body: <p>I got the following HTML:</p>
  
  <pre><code>&lt;video width="552" height="572" id="video" autoplay preload="none" poster="image.png"&gt;
  </code></pre>
  
  <p>How would I go about removing <code>autoplay</code> entirely from the <code>&lt;video&gt;</code> element?</p>
  
  <p>I've tried something like the following:</p>
  
  <pre><code>//Attempt
  jQuery('video').remove('autoplay');
  
  //Attempt
  jQuery( 'video' ).removeClass( 'autoplay' );
  </code></pre>
