AJAX and user leaving a page

Question

I\'m working on a chat and I\'m trying to figure out how I can detect that the user has left the page or not. Almost everything is being handled by the database to avoid the fro

Answer 1

Try this:

$(window).unload(function(){
    $.ajax({
        type: 'POST',
        url: 'script.php',
        async:false,
        data: {key_leave:"289583002"}
    });
});

Note the async:false, that way the browser waits for the request to finish.

Using $.post is asynchronous, so the request may not be quick enough before the browser stops executing the script.
