title: Open JS pop-up when Submit is clicked
body: <p>I have a contact form on my web site included where visitors have to fill in their name, address and email and now I try to add a content locker (javascript) which shall appear once they click on the "submit" button. The "onclick" works but the site automatically moves forward to the "submit.php" site and closes the content locker in seconds. I also want to have the visitors data already saved in case they close the site without paying attention to the PopUp. Is this possible?</p>
  
  <p>Regards</p>
