[jQuery] Getting a div with scroll bar to stay scrolled down

[Eric]

Hi all,

I have a div that will refresh itself and the scroll bar just won't
stay down. The solution I've found is:

        var objDiv = document.getElementById("divname");
        objDiv.scrollTop = objDiv.scrollHeight;

This doesn't work:
$('#divname').scrollTop = $('#divname').scrollHeight;

Therefore is there a more jquery-like way of doing it other than using
plugins perhaps?

Thanks.

Eric
