How to hide PHP URLs and without reloading page?

Question

I have two questions in mind to ask you guys here, I'm working everyday with PHP scripts but I don't know very good javascript so my questions are:

I have script and for every navbar I'll click or button then page will refresh, So can I get any method from you guys, how to show IMG LOADER instead reloading page?

Also per example: For button called "Update", in PHP I use /update.php?id=10 , Can I hide parameters just to be in URL: /update.php and to works like with parameter, and to show client IMG loader instead refreshing page/

Please, Just tell me methods which I can use to do them!

  <script type="text/JavaScript">
     <!--
        function AutoRefresh( t ) {
           setTimeout("location.reload(true);", t);
        }
     //-->
  </script>

This page will refresh every 5 seconds.
