title: Simple onkeydown + length count
body: <p>I have a very simple function here: </p>
  
  <pre><code>$('#input').keydown( function(e) {
  
      if( $(this).length === 8 ) { alert('We have a winner!'); }
      else { return false; }
  
  });
  </code></pre>
  
  <p>It does not work. Why? Any help much appreciated. </p>
