window.onbeforeunload = function(){


     $.ajax({

I am trying to destroy session if user pressed (X) in tab

I used the onbeforeunload event but the session is destroyed each time when I click the "Submit" button in the form or just refreshing the page

</div>

Keep a flag to check whether you clicked on a Submit button or Close button of browser.

<script>
var btnClickedFlag = false;
window.onbeforeunload = function(){

  if(!btnClickedFlag){
    $.ajax({
      type: "GET",
      url: "page/out.php"
    });
  }    
}

$('button').click(function(){
  btnClickedFlag = true;
});
</script>

Hope this will help you.
