React -创建具有动态输入数量的表单

import React, { useState } from 'react';

const DynamicForm = () => {
  const [inputs, setInputs] = useState(['']);

  const handleInputChange = (index, value) => {
    const newInputs = [...inputs];
    newInputs[index] = value;
    setInputs(newInputs);
  };

  const handleAddInput = () => {
    setInputs([...inputs, '']);
  };

  const handleRemoveInput = (index) => {
    const newInputs = [...inputs];
    newInputs.splice(index, 1);
    setInputs(newInputs);
  };

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

  return (
    <form onSubmit={handleSubmit}>
      {inputs.map((input, index) => (
        <div key={index}>
          <input
            type="text"
            value={input}
            onChange={(e) => handleInputChange(index, e.target.value)}
          />
          <button type="button" onClick={() => handleRemoveInput(index)}>
            删除
          </button>
        </div>
      ))}
      <button type="button" onClick={handleAddInput}>
        添加输入
      </button>
      <button type="submit">提交</button>
    </form>
  );
};

export default DynamicForm;
