以下是我目前的代码，它输出了我输入的名称，但我想创建一个重置按钮，将状态清空为一个空状态

import { useState } from "react";

function resetName() {
  this.firstName.value = "";
  this.lastName.value = "";
}
export default function Test() {
  const [firstName, setFirstName] = useState("");
  const [lastName, setLastName] = useState("");

  const fullName = `${firstName} ${lastName}`;

  return (
    <div>
      名字：
      <input
        value={firstName}
        onChange={(e) => setFirstName(e.target.value)}
      />{" "}
      <br />
      姓氏：{" "}
      <input
        value={lastName}
        onChange={(e) => setLastName(e.target.value)}
      />{" "}
      <br />
      {fullName}
      <br />
      <button value={resetName}>重置！</button>
    </div>
  );
}
