兄弟组件可通过 prop 与回调函数式的 prop 进行通信
import { useState } from "react";
import "./styles.css";
function One({ count, setCount }) {
return (
<div style={{ border: "1px solid red" }}>
<h2>Conponent One</h2>
<button onClick={() => setCount(count + 1)}>Click</button>
<div>{count}</div>
</div>
);
}
function Two({ count, setCount }) {
return (
<div style={{ border: "1px solid red" }}>
<h2>Conponent Two</h2>
<button onClick={() => setCount(count + 1)}>Click</button>
<div>{count}</div>
</div>
);
}
export default function App() {
const [count, setCount] = useState(0);
return (
<div className="App">
<One count={count} setCount={(c) => setCount(c)} />
<Two count={count} setCount={(c) => setCount(c)} />
</div>
);
}
