向映射函数添加条件

Question

我有这个map功能：

  return docTypes.map(docType => ({
    label: docType.docType,
    value: docType.id,
  }));

如何添加条件以仅返回 if docType.generic = true？

Answer 1

filter在您的之前添加map：

return docTypes.filter(docType => docType.generic).map(docType => ({
  label: docType.docType,
  value: docType.id,
}));
