title: jQuery accessing html5 data attribute
body: <p>On click of one of the options I am trying to get the data value from the 'ul li a' and place it into button below, I've set up a fiddle example here: <a href="http://jsfiddle.net/q5j8z/4/">http://jsfiddle.net/q5j8z/4/</a></p>
  
  <p>But cant seem to get it working</p>
  
  <pre><code>$('ul li a').click(function(e) {
      e.preventDefault();
  
      var value = $(this).data();
  
      $('.button').data('value');
  });
  </code></pre>
  
  <p>Does anyone have any ideas please?</p>
