jQuery - Partial page refresh

If you need to refresh only a portion of a page, the 3 lines of code below will definitely help. In this example, a #refresh div is automatically refreshed every 10 seconds.

setInterval(function() {
    $("#refresh").load(location.href+" #refresh>*","");
}, 10000); // milliseconds to wait
