[jQuery] scrollTo jScrollPane using each()

[dcasey]

I can't figure out how to scroll ALL my panes to the top.
Here is the pertinent code:

// dynamically assign ids and jScrollPane, I would rather not assign
any IDs...
$('.scrollpane').each(function(n) {
     $(this).attr('id', 'scrollpane'+n);
     $(this).jScrollPane({showArrows:true, scrollbarWidth: 11});
});
etc...

function scrollAllToTop() {
    $('#scrollpane1')[0].scrollTo(0); // will scroll that one id to
the top, just as described

    // but, why doesn't this work? I keep getting $(this)[0].scrollTo
is not a function
    $('.scrollpane').each(function() {
        //alert($('#scrollpane1')[0] == $(this)[0]); // yup it finds
one same object in the list...
        $(this)[0].scrollTo(0);
    });
}
