[jQuery] Changing Method Values on the Fly

[jQuery] Changing Method Values on the Fly


I want to dynamically change the function value of the submitHandler:
method. How can I do this?
Here is some sample code:
----------------
        $('#update_inventory').validate({
            submitHandler: function(form) {
                                    $(form).ajaxSubmit({
                                        target: '#inventory',
                                        success: parseResponse
                                    });
                                },
            debug: true,
            errorElement: "em",
            errorContainer: $("#warning, #summary"),
            errorPlacement: function(error, element) {
                error.appendTo( element.parent("span").next("span") );
            },
            success: function(label) {
                label.text("ok!").addClass("success");
            }
        });
