在react中提升表单提交的数据

// 父组件
import React, { useState } from 'react';
import ChildComponent from './ChildComponent';

function ParentComponent() {
  const [formData, setFormData] = useState({ name: '', email: '' });

  const handleFormSubmit = () => {
    // 在这里可以进行表单提交的操作，使用formData中的数据
    console.log(formData);
  };

  const handleInputChange = (e) => {
    const { name, value } = e.target;
    setFormData((prevData) => ({
      ...prevData,
      [name]: value,
    }));
  };

  return (
    <div>
      <ChildComponent
        formData={formData}
        onInputChange={handleInputChange}
        onFormSubmit={handleFormSubmit}
      />
    </div>
  );
}

export default ParentComponent;

// 子组件
import React from 'react';

function ChildComponent({ formData, onInputChange, onFormSubmit }) {
  return (
    <form onSubmit={onFormSubmit}>
      <input
        type="text"
        name="name"
        value={formData.name}
        onChange={onInputChange}
      />
      <input
        type="email"
        name="email"
        value={formData.email}
        onChange={onInputChange}
      />
      <button type="submit">提交</button>
    </form>
  );
}

export default ChildComponent;
