  .then(function (parts) {
    for (var name in parts.fields) {
      var field = parts.fields[name];
      console.log('field name:', field.value, 'value:', field.value);
    }

    for (var name in parts.files) {
      var file = parts.files[name];
      console.log('file field name:', file.value);
    }
