Question

How can I use AJAX to check a file, like, every 30 seconds, and then just print the result? I would prefer to use jQuery, but just plain javascript is okay too.

P.S.
I’ve been searching for how to do this for a while.

Something like this should help:

function getData() {
    $.get("filepath", function (data) {
        // process data...
        console.log(data);

        // Invoke the data lookup again after 30s
        window.setTimeout(function () { 
            getData();
        }, 30000); // 30s
    });
}

And then invoke the starting of the loop:

$(document).ready(function () {
    getData();
});
