[jQuery] sending an array[] with $.ajax post


hi
i've got an array made after a selection of checkboxes and i want to
send this values to a php page to do some sql query.
i couldn't manage to pass the values via post and this is my function
var myFunction = function() {
        $("#cancellaRecord").click(function() {
            if (confirm("sei sicuro di voler cancellare questi record?")){
                arrayCheckBox = new Array;
                arrayCheckBox = $("#selezionaCancella input:checked");
                $.ajax({type: "POST",
                    url: "effettuaCancellazioneMultipla.php",
                    data: what should i write here??? how should i send my
arrayCheckBox values??
                    success: function(){
                        alert("success")
                        }
                });
            } else {
                alert("non cancellato");
            }
        });
    }
Any idea?
thanks vitto
