Look at this
Ajax tutorial for post and get

So, the jQuery

$('body').on('submit', '#contact-form', function(){
  $.post({$(this).attr("action"), $(this).serialize(), function(data){
    if(data){
      alert(data.message);
    }
  }, 'json');
  return false;
});

And the server side

<?php 
  if($_SERVER['REQUEST_METHOD'] === 'POST'){
    // do your thing here
    echo json_encode(array("message" => make_clickable($tosay).$link_delete));
    die();
  }
?>
