title: Possible causes of Cannot read property constructor of undefined
body: <p>I want to iterate over all the forms present in a div. So I am using the following code for this</p>
  
  <pre><code>$('#divid form').each(function (index, formDetails) {
      if (formDetails) {
          console.log($(formDetails).attr('id'));
      }
  });
  </code></pre>
  
  <p>This is working fine in Mozilla with no issues but when I run this code in Chrome sometimes it throws the following error.</p>
  
  <p>This error is coming</p>
  
  <blockquote>
    <p>Uncaught TypeError: Cannot read property 'Constructor' of undefined</p>
  </blockquote>
  
  <p>I am using Version 33.0.1750.117 m of Chrome.</p>
  
  <p>Why this error is coming I am not able to understand?</p>
