title: Jquery "$("*:focus")" is empty. How to detect where is the focus?
body: <p>Im working with jQuery. There are input fields with ID's and attached .blur() events. The problem comes when I try to figure out the very new item where the focus is on:</p>
  
  <pre><code>$("#"+field).blur(function()
  {
   console.log ($(this).attr('id')+' -&gt; '+$("*:focus").attr('id'));
  }
  </code></pre>
  
  <p>but this <strong>$("*:focus").attr('id')</strong> is undefined. How to detect where is the focus?</p>
