onbeforeunload not supported in iOS about timeme.js HOT 3 OPEN

This is what I use for iPhone iPad and iPod. It seems to work if someone wants to test and give me feedback (and maybe update documentation)

<script type="text/javascript">
    TimeMe.setIdleDurationInSeconds(30);
    TimeMe.setCurrentPageName("NAME_OF_THE_PAGE");
    TimeMe.initialize();
    var isOnIOS = navigator.userAgent.match(/iPad/i) || navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPod/i);
    var eventName = isOnIOS ? "pagehide" : "beforeunload";

    window.addEventListener(eventName, function (event) { 
        xmlhttp = new XMLHttpRequest();
        xmlhttp.open("POST", 'URL', false);
        xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        var timeSpentOnPage = TimeMe.getTimeOnCurrentPageInSeconds();
        xmlhttp.send("timeSpent=" + timeSpentOnPage);
    });

</script>

Hi! Thanks for the comment. There are timing issues with onbeforeunload, especially when trying to send a synchronous HTTP request as my documentation suggests to do. I'm not surprised to hear that iOS is not supporting this.

I'll update documentation to find another suggestion, but it may involve websockets or some other pinging mechanism.

I've been play with TimeMe and Ratchet and have it all working nicely, except iOS. Is this due to the sendCurrentTime call that should be triggered by an onbeforeunload that never runs on iOS?
