反应本机:失败的道具类型:Prop BusinessPhoneNumberchanged已根据需要标记

Question

我有一个反应本机应用程序，其中会员可以更改其业务电话号码，但是一旦用户保存并关闭了该屏幕，该电话号码不会持续存在。

有一个警告说：

失败的道具类型：Prop BusinessPhonenumberchanged被标记为在BusinessDetailsform中需要，但其价值不确定。

我想知道这是否与BusinessDetailsForm是一个功能组件有关，这意味着必须有一个正在向其传递道具的父组件，而且我在任何地方都没有将其父件找到：

这是功能组件：

我看不到此businessPhoneNumberChanged的父组件。当我使用道具时，我会将此BusinessDetailsForm制成基于类的组件，但我不确定这是否是问题。我总是认为人们知道他们在做什么。

道具类型的作用对我来说也不清楚100％，因为我没有使用太多。

所以我自己的理论，为什么businessPhoneNumberChanged的价值不确定？

我唯一发现的是父组件是 BusinessDetails：

Answer 1

在父组件中，prop businessPhoneNumberChanged实际上是呼叫 而不是传递函数本身。尝试更改此问题：

businessPhoneNumberChanged={getGoodBusinessPhoneNumber(this._businessPhoneNumberChanged)}

：

businessPhoneNumberChanged={() => getGoodBusinessPhoneNumber(this._businessPhoneNumberChanged)}
