On form submit, take the user to a new page and leave behind the old tab in the background


I’m trying to create a leave behind landing page where the user, upon submitting their zip code on a form are:

  1. Taken to a page in a new tab in their browser, with their zip code passed into the URL
  2. The tab left behind (the original landing page) opens a lightbox, also with their zip code fed into it 


Why do you need need a new tab to do so when you can just use the lightbox? Is there something else you’re trying to accomplish?
