php ajax window close problem

Question

i have a php web application, where i use an authentication method. I have a script logout.php in the same directory as the index file. I want that the code in the logout.php be executed if the used mid session decides to exit or navigate away from the page.

ive tried using

function closeIt()
{
    var exit = confirm("Are you sure you want to end this chat session ?");
    if(exit==true){
$.ajax({
   type: "GET",
   url: "logout.php",
   success: function(){ alert("Done");}
 });
    }
}

window.onbeforeunload = closeIt;

i get the confirm box, but i am not getting success, am i doing somethign worng or do i need a new approach all together ?

have you used firebug or something to see if the AJAX call is failing? — Munzilla

The Ajax call is performed asynchronously, so the call is made and processing is passed back to the page immediately, which then closes before the ajax call completes.

You need to make a synchronous call to make this work.

A in AJAX stands for asynchronous. You may want to use synchronous XMLHttpRequest or return false at the end of closeIt() (that should prevent closing window) and in your success function, change onbeforeunload to null and close the window with window.close()
