react-day-picker - 为 react-day-picker 添加一个类？

Question

如何将类添加到 react-day-picker 的今天按钮？

从文档中似乎是可能的:
http://react-day-picker.js.org/api/DayPicker#classNames

const dayPickerClassNames = { todayButton: 'newClass' };

<DayPicker
  classNames={dayPickerClassNames}
/>

但是我收到一个错误:

Warning: Failed prop type: The prop `classNames.day` is marked as required in `DayPicker`, but its value is `undefined`.

根据 API，它需要以下键(即，它需要容器、包装器、..months..month..day.. 等键)，但您只提供 todayButton 键/值，显然您需要提供每个键/值对。

您应该能够导入默认值 classNames对象，然后只需更新 todayButton像这样的值(value):

import classNames from '../classNames' // this path is probably not correct

const dayPickerClassNames = { ...classNames, todayButton: 'newClass' };

<DayPicker
  classNames={dayPickerClassNames}
/>
