[jQuery] click function populating value in a hidden field

[Chuk]

Hi.  I have a table set up with a .click() function on each row so
that if it is clicked on, a class is added to the row thus changing
the background, etc.  I was wondering if there was is a way to take
the id of the row that was clicked and populate a hidden field with
it.  What would I need to include in my .click() function for this to
work?

Here is my current one:
$("tr").click(function () {
    $(".clicked").removeClass("clicked");
    $(this).addClass("clicked");
});
