How to execute ajax function onbeforeunload?
javascript, jquery, onbeforeunload, php
Solution
You fire your ajax async (default for jquery - ajax). But the browser won't wait for anything on unload.
try setting `async : false` in the ajax-settings. But you can never be sure that this will work in all browsers everytime.

Problem
I'm developing a php/javascript chat. When the user logs in, his/her username is inserted in a MySQL table called `queue`. This insert returns the `mysql_insert_id()` that will be stored in a session variable called `$_SESSION['CHAT_QUEUE_ID']` I need the MySQL table row to be deleted when the user closes the page. I tried the following, but without success: js file ``` window.onbeforeunload = closeSession; function closeSession(){ $.ajax({ url: "/chat/process/chat.php", type: "GET" }); return "disconnected"; } ``` chat.php ``` $delete= "DELETE FROM queue WHERE id = " . $_SESSION['CHAT_QUEUE_ID']; // query, etc ``` Is there any way to do this?
