使用React动态添加和删除输入元素

import React, { useState } from 'react';

function DynamicInput() {
  const [inputValues, setInputValues] = useState(['']);

  const handleAddInput = () => {
    setInputValues([...inputValues, '']);
  };

  const handleRemoveInput = (index) => {
    const newInputValues = [...inputValues];
    newInputValues.splice(index, 1);
    setInputValues(newInputValues);
  };

  const handleChangeInput = (index, value) => {
    const newInputValues = [...inputValues];
    newInputValues[index] = value;
    setInputValues(newInputValues);
  };

  return (
    <div>
      {inputValues.map((value, index) => (
        <div key={index}>
          <input
            type="text"
            value={value}
            onChange={(e) => handleChangeInput(index, e.target.value)}
          />
          <button onClick={() => handleRemoveInput(index)}>删除</button>
        </div>
      ))}
      <button onClick={handleAddInput}>添加</button>
    </div>
  );
}

export default DynamicInput;
