title: Toggle multiple <span> with the same id
body: <p>This shows the hidden numbers on click only on the first occurrence. I am not sure how to make it work if there are multiple  <code>&lt;span id="number"&gt;</code> within the same text. I wouldn't even mind if they would all show when one of them is clicked. Or they can show independently. Either way. </p>
  
  <pre><code>&lt;script&gt;
  $(function(){
  $('#number').click(function() {
  $(this).find('span').text( $(this).data('last') );
  });
  });
  &lt;/script&gt;
  
  &lt;span id="number" data-last="1234"&gt;5678&lt;span&gt;****&lt;span class="showphone"&gt;Show&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;
  </code></pre>
