React -如何处理嵌套表单及其值

import React, { useState } from 'react';

const NestedForm = () => {
  const [formValues, setFormValues] = useState({
    name: '',
    email: '',
    address: {
      street: '',
      city: '',
      state: ''
    }
  });

  const handleChange = (event) => {
    const { name, value } = event.target;
    setFormValues(prevState => ({
      ...prevState,
      [name]: value
    }));
  };

  const handleNestedChange = (event) => {
    const { name, value } = event.target;
    setFormValues(prevState => ({
      ...prevState,
      address: {
        ...prevState.address,
        [name]: value
      }
    }));
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    // 处理表单提交逻辑
  };

  return (
    <form onSubmit={handleSubmit}>
      <label>
        Name:
        <input type="text" name="name" value={formValues.name} onChange={handleChange} />
      </label>
      <label>
        Email:
        <input type="email" name="email" value={formValues.email} onChange={handleChange} />
      </label>
      <label>
        Street:
        <input type="text" name="street" value={formValues.address.street} onChange={handleNestedChange} />
      </label>
      <label>
        City:
        <input type="text" name="city" value={formValues.address.city} onChange={handleNestedChange} />
      </label>
      <label>
        State:
        <input type="text" name="state" value={formValues.address.state} onChange={handleNestedChange} />
      </label>
      <button type="submit">Submit</button>
    </form>
  );
};

export default NestedForm;
