title: How to hide PHP URLs and without reloading page?
body: <p>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:</p>
  
  <p>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?</p>
  
  <p>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/</p>
  
  <p>Please, Just tell me methods which I can use to do them!</p>
