title: Update data on a page without refreshing
body: <p>I have a website where I need to update a status.
  Like for a flight, you are departing, cruise or landed.
  I want to be able to refresh the status without having my viewers to have and reload the whole page. I know there is a way to do it with AJAX and jQuery, but I don't have any understanding of how that works. I also don't want them to have and click a button.
  If anybody knows how that would be done I much appreciate it!</p>
