I need to track my users time on website using javascript. My website is only one page long so something like piwik or google whatever is too heavy handed. How can I generate a random 12 letter long id (for example “sEjhWixldIdy”) when the user first connects and repeatedly ping “example.com/tracker.py?id=sEjhWixldIdy” every 1000 milliseconds or so. I know how to do the python end of it, but how to do the client side?

EDIT:
is this possible without using jQuery?

    The easiest strategy to achieve this in vanilla JS is probably to add an image on the page (src = your Python file) and update it every second:

    <html>
    ...
    <script type="text/javascript">
        var img = document.createElement("IMG"),
            trackerId = Math.random(); // replace Math.random() with another ID generator.

        img.style.display = "none";
        document.body.appendChild(img);

        setInterval(function() {
                img.src = "http://example.com/tracker.py?id=" + trackerId + "&cacheb=" + Math.random();
            }, 1000);
    </script>
</body>
</html>

    Alternatively, you can use the XMLHttpRequest object (and do a POST to eliminate cache-related issues):

    var oHttp = new XMLHttpRequest(),
    trackerId = Math.random(); // replace Math.random() with another ID generator.;

setInterval(function() {
        oHttp.open("post", "http://example.com/tracker.py", true);
        oHttp.send("id=" + trackerId);
    }, 1000);
