Initially loading the page
Navigating to the page from another page in the same window or tab
Restoring a frozen page on mobile OSes
Returning to the page using the browser's forward or back buttons

During the initial page load, the pageshow event fires after the load 事件。

  "unload", "load"
];
const eventLogger = event => {
  switch (event.type) {
    case "pagehide":
    case "pageshow":
      let isPersisted = event.persisted ? "persisted" : "not persisted";
      console.log('Event:', event.type, '-', isPersisted);
      break;
    默认：
      console.log('Event:', event.type);
      break;
  }
