Question

how do I change the code below so that multiple elements with ids can be returned (actions to happen to more elements than just the one with id=”firstId”). Thanks in advance.

   $("#main").change(function() {
    var first = $(this);
    $('#occupation').prop("disabled", function() {
        return first.children(":selected").attr("id") === ("firstId");
    });
});

var ids = ["firstId", "secondId"];
$("#main").change(function() {
    var first = $(this);
    $('#occupation').prop("disabled", function() {
        return jQuery.inArray(first.children(":selected").attr("id"), ids) !== -1;
    });
});
