title: jQuery: how do I check if an element is the last sibling?
body: <p>How do I check if an element is the last sibling?</p>
  
  <p>For the last cell in a row I want to perform a different action.</p>
  
  <p>This doesn't work:</p>
  
  <pre><code>$('td').each(function(){
      var $this = $(this);
      if ( $this === $this.parent().last('td') )
          {
              alert('123');
          }
  })
  </code></pre>
  
  <p>And neither does it if I remove <code>.parent()</code>.</p>
