有没有办法将选中/勾选的项保存到数组中？

// HTML
<input type="checkbox" value="item1" onchange="handleCheckboxChange(event)">
<input type="checkbox" value="item2" onchange="handleCheckboxChange(event)">
<input type="checkbox" value="item3" onchange="handleCheckboxChange(event)">

// JavaScript
let selectedItems = [];

function handleCheckboxChange(event) {
  const value = event.target.value;
  if (event.target.checked) {
    selectedItems.push(value);
  } else {
    const index = selectedItems.indexOf(value);
    if (index > -1) {
      selectedItems.splice(index, 1);
    }
  }
}

import React, { useState } from 'react';

function CheckboxList() {
  const [selectedItems, setSelectedItems] = useState([]);

  const handleCheckboxChange = (event) => {
    const value = event.target.value;
    if (event.target.checked) {
      setSelectedItems([...selectedItems, value]);
    } else {
      setSelectedItems(selectedItems.filter(item => item !== value));
    }
  };

  return (
    <div>
      <input type="checkbox" value="item1" onChange={handleCheckboxChange} />
      <input type="checkbox" value="item2" onChange={handleCheckboxChange} />
      <input type="checkbox" value="item3" onChange={handleCheckboxChange} />
    </div>
  );
}
