[jQuery] jquery - adding flexibility to a function

[TheOriginalH]

    <script src="jquery-latest.js" type="text/javascript"></script>
    <script type="text/javascript">
        function loadContent(id) {
            $("#contentArea").load("rpc.php?o="+id+"");
        }
    </script>

Works well, but I'd like the function to work for an area with a
variable div. So if the function is called with an id of 6, it loads
the content to "#contentArea6". Any ideas on how to achieve it? TIA.
