show element if class matches current body id (Please help)

show element if class matches current body id (Please help)

hi Im new to jquery and having some trouble adapting the code below. the function is for a accordion menu. I want it to recognize the body's id, and show the sub menu who's class matches the body id. right now it is set to show the submenu with class="test".

function initMenu() {

$('#menu ul').hide();
$('#menu ul.test').show();
$('#menu li a').click(
function() {
$(this).next().toggle();
}
);
}
$(document).ready(function() {initMenu();});


do i start with something allong the lines of
var bodyid = $("body").attr("id");
?

Any suggestions greatly appreciated.

Thanks
