React表单在提交POST后不清除输入

import React, { useState } from 'react';

function Form() {
  const [inputValue, setInputValue] = useState('');

  const handleSubmit = (e) => {
    e.preventDefault();
    // 提交表单的逻辑处理
    setInputValue('');
  };

  return (
    <form onSubmit={handleSubmit}>
      <input
        type="text"
        value={inputValue}
        onChange={(e) => setInputValue(e.target.value)}
      />
      <button type="submit">提交</button>
    </form>
  );
}

import React, { useRef } from 'react';

function Form() {
  const inputRef = useRef(null);

  const handleSubmit = (e) => {
    e.preventDefault();
    // 提交表单的逻辑处理
    inputRef.current.value = '';
  };

  return (
    <form onSubmit={handleSubmit}>
      <input type="text" ref={inputRef} />
      <button type="submit">提交</button>
    </form>
  );
}

import React, { useRef } from 'react';

function Form() {
  const formRef = useRef(null);

  const handleSubmit = (e) => {
    e.preventDefault();
    // 提交表单的逻辑处理
    formRef.current.reset();
  };

  return (
    <form ref={formRef} onSubmit={handleSubmit}>
      <input type="text" />
      <button type="submit">提交</button>
    </form>
  );
}
