如何为两个独立的函数设置本地存储(暗光模式)

// 设置暗光模式
function setDarkMode(enabled) {
  localStorage.setItem('darkMode', enabled ? 'true' : 'false');
}

// 获取暗光模式状态
function getDarkMode() {
  const darkMode = localStorage.getItem('darkMode');
  return darkMode === 'true';
}

// 示例使用
document.getElementById('toggleDarkMode').addEventListener('click', () => {
  const isEnabled = getDarkMode();
  setDarkMode(!isEnabled);
  updateUI(!isEnabled);
});

function updateUI(isDarkMode) {
  const body = document.body;
  if (isDarkMode) {
    body.classList.add('dark-mode');
  } else {
    body.classList.remove('dark-mode');
  }
}

// 初始化UI状态
document.addEventListener('DOMContentLoaded', () => {
  updateUI(getDarkMode());
});

body.dark-mode {
  background-color: #121212;
  color: #ffffff;
}

function getDarkMode() {
  try {
    const darkMode = localStorage.getItem('darkMode');
    return darkMode === 'true';
  } catch (error) {
    console.error('Failed to read dark mode from localStorage', error);
    return false; // 默认值
  }
}
