以下是有關(guān)如何執(zhí)行此操作的示例：
import React, { useState } from "react";
import "./style.css";
export default function App() {
? const [name, setName] = useState("");
? const [number, setNumber] = useState("");
? const [serverData, setServerData] = useState([]);
? const handleSubmit = event => {
? ? event.preventDefault();
? ? setServerData(serverData.concat({ name: name, number: number }));
? ? setName("");
? ? setNumber("");
? ? console.log(serverData);
? };
? const sendToServer = () => {
? ? console.log("server ko post request with following data...");
? ? console.log(serverData);
? ? setName("");
? ? setNumber("");
? };
? return (
? ? <div>
? ? ? <form onSubmit={handleSubmit}>
? ? ? ? <input value={name} onChange={e => setName(e.target.value)} />
? ? ? ? <input value={number} onChange={e => setNumber(e.target.value)} />
? ? ? ? <button>add data</button>
? ? ? </form>
? ? ? <button onClick={sendToServer}>Submit to server</button>
? ? </div>
? );
}
