Jquery check value change across multiple Dropdownlist

I wanting to know is it possible to check the change of like Dropdownlist in one jquery function.
Currently I can check the change of one or another control, ie.   $('#<%= Allergies1DDL.ClientID %>').change(function () {... and then do the same for    $('#<%= Allergies2DDL.ClientID %>').change(function () {...  

But I would like to combine the change event to listen for change using an OR operator like,
 $('#<%= Allergies1DDL.ClientID %>' || '#<%= Allergies2DDL.ClientID %>').change(function () {...

Is this possible?  When I run the program the first item is only works.

//This section checks DropdownList on change if 'Other' has been selected if it has then Open Jquery UI and allow user to add item.
    $(document).ready(function () {
        $('#<%= Allergies1DDL.ClientID %>').change(function () {
            var aDDL = $(this).val();
            if (aDDL == "-1") {
                //Open Jquery Dialog             
                addDDLOpenDialog(-1, "Allergies");
            }
        });
    });
