Как добавить захват select и textarea в ajax отправке письма?

$(function() {
        $('#writeAppointment').on('submit', function(e){
            e.preventDefault();
            var form = $(this);
            var data = new FormData();
            form.find(':input[name]').not('[type="file"]').each(function() {
                var field = $(this);
                data.append(field.attr('name'), field.val());
            });
            var filesField = form.find('input[type="file"]');
            var fileName = filesField.attr('name');
            var file = filesField.prop('files')[0];
            data.append(fileName, file) ;

            var url = 'multisend.php';

            $.ajax({
                url: url,
                type: 'POST',
                data: data,
                contentType: false,
                cache: false,
                processData:false,
                success: function(response) {
                    console.log(response)
                }
            });
        })
    });
