I have a page with the following:

<script>
    window.setInterval(function () {
        var cookie = $.cookie('download');
            if (cookie !== null) {
                console.log(cookie);
            }
    }, 500); 
</script>

It is checking a cookie called download and its value of 0 (previously set) is being displayed in the console.

From this page I can click a button which launches a php pdf generating file and just before the pdf is output (to download the pdf) have: 

<?php 
    ... pdf created ...
    setcookie("download", 1);
    output pdf;
?>

suposedly to mark set the cookie as 1 to indicate the download is complete. However this change is not reflected in the console and the cookie remains with the value 0.

Is what I am trying to do possible? And if so what am I doing wrong?

This method is proposed with this question: Is there any event/way we can know when a file has finished downloading?

    Cookies are sent in response header. Even tho I'm not sure what are you trying to accomplish, you can't expect that cookie will simply appear like that. – Mladen Ilić Sep 01 '16 at 12:11
  • I am trying to acheive a way of knowing when a pdf file generated by php has downloaded. It is asked a great deal and I have included the link of a method. So I need to find out how to read the header in the output - is that what you are saying? – RGriffiths Sep 01 '16 at 12:14
  • The cookie is there - it is displaying 0 - what I want to do is to change it to 1 when the pdf has completed downloading. – RGriffiths Sep 01 '16 at 12:15
