Answer 1

You can make ajax request on

window.onbeforeunload = function(){ 
    ////make ajax request
}

Or can prevent the user by giving confirm box

function showalert() {
  if (!confirm('Are you sure you want to exit without saving changes?')) { 
     ////make ajax request
  }
  else {return true;}
}

window.onbeforeunload = function(){ showalert }

For example check this out when I leave this page while answering SO prevent me
