⚠️ 报错分析

原文：[Deprecation]Listener added for a 'DOMNodeRemovedFromDocument' mutation event. This event type is deprecated, and will be removed from this browser VERY soon. Usage of this event listener will cause performance issues today, and represents a large risk of imminent site breakage. Consider using MutationObserver instead.
译文：[弃用警告]已为 'DOMNodeRemovedFromDocument' 变异事件添加监听器。此事件类型已被弃用，并将很快从浏览器中移除。目前使用此事件监听器会导致性能问题，并存在网站即将损坏的重大风险。建议改用 MutationObserver。

🎯 原因分析

💡 解决方案

// 旧版代码（已弃用）
// document.addEventListener('DOMNodeRemovedFromDocument', (event) => {
//   console.log('节点从文档中移除:', event.target);
// });

// 推荐使用MutationObserver
const observer = new MutationObserver((mutationsList, observer) => {
  for (const mutation of mutationsList) {
    if (mutation.type === 'childList') {
      mutation.removedNodes.forEach(node => {
        console.log('节点从文档中移除:', node);
      });
    }
  }
});

// 配置观察选项：监听子节点移除，并设置子树扩展以覆盖深层变动
observer.observe(document.body, {
  childList: true,
  subtree: true
});
