I'm trying to update the LastName field for PersonID. I can pass PersonID, but I don't know the syntax for also passing the LastName field.

$('input[name="LastName"]').live('focusout', function() {
    var PersonID = $(this).parents("tr").attr("ID");
    var LastName = $(this).val(); // todo: serialize
    $.ajax({
        url:'Remote/Person.cfc?method=UpdateLastName&returnformat=json'
        ,data:'PersonID='+PersonID
    });
    $(this).parents("td").empty().append(LastName);
});

Q: Is is something like data:{'PersonID='+PersonID,'LastName='+LastName}

Am I missing a squiggly line or a parenthesis or comma or dot or colon or semi-colon or something?
