下面代码复制不了 检测bug 并且优化写出代码button id=copy-button class=refresh-button复制buttonscriptconst copyButton = documentgetElementByIdcopy-button;const responseTextarea = documentgetElementByIdchatgpt-response;copy

<p><button id="copy-button" class="refresh-button">复制</button></p>
<textarea id="chatgpt-response"></textarea>
<script>
const copyButton = document.getElementById('copy-button');
const responseTextarea = document.getElementById('chatgpt-response');

copyButton.addEventListener('click', () => {
  responseTextarea.select();
  document.execCommand('copy');
});

// 优化部分
// 检测浏览器是否支持 execCommand
if (!document.queryCommandSupported('copy')) {
  copyButton.style.display = 'none';
}

// 添加复制成功提示
responseTextarea.addEventListener('copy', (event) => {
  event.preventDefault();
  if (event.clipboardData) {
    event.clipboardData.setData('text/plain', responseTextarea.value);
    console.log('复制成功！');
  }
});
</script>
