Confirm beforeunload ajax jquery

Question

Hi I need to confirm with ajax before leave the page but with confirm('message') I have a bug

$( window ).on( "beforeunload", function(){
    confirm('message');
    $.ajax({
        type: "GET",
        async: false,
        url: 'page.php',
        success: function(dat) {
            alert(dat);
        }
    });
});

You have a idea for confirm before ajax?

please add more detail of problem, btw if you don't test the return value of confirm the confirm its useless — ale, Sep 06 '14 at 17:29
this is just not a reliable way to do server communications, do it long before unload — charlietfl, Sep 06 '14 at 17:32

confirm() returns a boolean. You need to check it's value before continuing.

if(confirm("Do you want to AJAX something?") {
$.ajax({
            type: "GET",
            async: false,
            url: 'page.php',
            success: function(dat) {
                alert(dat);
            }
        }); 
}

I'm not sure if you can do all this beforeUnload, though. I think that the confirm dialog will show up, but the AJAX won't finish before the page is unloaded. – Design by Adrian Sep 06 '14 at 17:31
Its work but in `$( window ).on( "beforeunload", function(){` not working why please ? – Mozinor Sep 06 '14 at 18:56
Please see answer posted by @BradChristie. In short: you can't do that inside a beforeunload. – Design by Adrian Sep 06 '14 at 19:00
