我是新来的反应,并试图创建一个基本的应用程序来交换两个值交换部分正在工作但第二个框的初始值已设置但对于第一个它正在工作
import React, { useState } from "react";
import "./App.css";
function Content(props) {
const { firstName, lastname } = props;
const [text1, setText1] = useState(firstName);
const [text2, setText2] = useState(lastname);
return (
<div className="content">
<input
type="text"
onChange={function (event) {
setText1(event.target.value);
}}
value={text1}
/>
<input
type="text"
onChange={function (event) {
setText2(event.target.value);
}}
value={text2}
/>
<button
onClick={function () {
// [text1 , text2] = [text2, text1]
setText1(text2);
setText2(text1);
}}
>
SWAP
</button>
</div>
);
}
function App() {
return <Content firstName={"First Name"} lastName={"Last Name"} />;
}
export default App;
