按下按钮时快速更新文本

// 示例代码：使用requestAnimationFrame优化更新
function updateText(newText) {
  requestAnimationFrame(() => {
    document.getElementById('textElement').innerText = newText;
  });
}

document.getElementById('button').addEventListener('click', () => {
  updateText('New Text');
});

// 示例代码：使用async/await处理异步更新
async function fetchDataAndUpdateText() {
  try {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    document.getElementById('textElement').innerText = data.text;
  } catch (error) {
    console.error('Error fetching data:', error);
  }
}

document.getElementById('button').addEventListener('click', fetchDataAndUpdateText);
