检测客户端与服务器端路由

Question

浏览网站时，除了检查下载的HTML文档的“网络”选项卡（在开发工具中）以外，是否有其他方法可以检测出它是使用客户端路由还是服务器端路由？

Answer 1

You could use the beforeunload event to decide what type of routing that is.

window.addEventListener('beforeunload', function (e) {
  console.log(e);

  // This is usually used to block user navigation, for example, when they have not saved cahnges
  /**
   * // Cancel the event
   * e.preventDefault();
   * // Chrome requires returnValue to be set
   * e.returnValue = '';
   */
});

To detect changes to DOM, you could use MutationObserver . But I would either useone or the other.
