Simple condition that returns true if document.activeElement = ""
<p>I need to know if the selected element has an ID. </p>

<p>What am I doing wrong?</p>

<pre><code>  var selected = document.activeElement;
  if (selected.id = "") {
  document.getElementById('test3').innerHTML= "is blank";    
  }
</code></pre>

<p>Thanks</p>
