[jQuery] How pass more variables in Star Rating System (AJAX Question)

Hi Folks

I saw that Star Rating System pass only the vote.

How can I add more variables? Something like this:

            $.post("url.php",
                  {
                  user: $('#user').attr('name'),
                  currenttime : $('#currenttime').attr("name"),
                  }

Regards
