Fake Zip Code Processing/Checking Overlay In Between Form Submit and Confirmation Page

Yeah it should be fairly easy to set it up.

You can set the form submission confirmation dialog box to open up a Lightbox that you can customize to give the impression that it is “Processing…” then include a script that will automatically redirect to another page after X amount of seconds.

Place this script on your lightbox after the form submission:

<script>
 
  (function(){
  
    // Your URL
    var url = 'https://your.url/';
  
    // Delay before the redirect takes place, in seconds
    var delay = 0;
    
     window.setTimeout(function() {
      window.open(url, '_top');
    }, delay * 1000);
  
  })();
 
</script>
