在 HOC 中使用 useState/Hooks 導致錯誤“Hooks can only be called inside of a function component”

Question

是否不允許在高階組件內部使用鈎子？ 當我嘗試使用這個簡單的模式執行此操作時，我收到錯誤Invalid hook call. Hooks can only be called inside of the body of a function component. Invalid hook call. Hooks can only be called inside of the body of a function component.

// App.js
import React, { useState } from 'react';

const WithState = (Component) => {
  const [state, dispatch] = useState(0);
  return () => <Component state={state} dispatch={dispatch} />;
}

const Counter = ({ state }) => {
  return (
    <div style={{ textAlign: 'center', margin: '0 auto'}}>
      {state}
    </div>
  )
}

const CounterWithState = WithState(Counter);

const App = () => {
  return <CounterWithState />;
}

export default App;

Answer 1

我相信你應該使用 HOC 中的鈎子：

const WithState = (Component) => {
  const WithStateComponent = () => {
    const [state, dispatch] = useState(0);
    return <Component state={state} dispatch={dispatch} />;
  }
  return WithStateComponent;
}

受 Rafael Souza 的回答啟發，您可以通過以下方式使其更加清潔：

const WithState = (Component) => {
  return () => {
    const [state, dispatch] = useState(0);
    return <Component state={state} dispatch={dispatch} />
  }
}
