The pageshow event is sent to a Window when the browser makes the window's document visible due to navigation tasks. This includes the process of initially loading the page, navigating to the page from another page within the same window or tab, or returning to the page using the browser's forward or back buttons.

When this event is sent during the page load process, it's sent after the load event.

Example

This example sets up event handlers for all of the events listed in the array events. The handler, eventLogger(), logs the type of event that occurred to the console, and includes the value of the persisted flag on pageshow and pagehide events.

JavaScript

const events = [
  "pagehide", "pageshow",
  "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;
    case "load":
    case "unload":
      console.log(`Event: ${event.type}`);
      break;
    default:
      console.log(`Event: ${event.type}`);
      break;
  }
};

events.forEach(eventName => {
  window.addEventListener(eventName, eventLogger, false);
});

HTML

<p>Open the console and watch the output as you navigate in and out of
this page. Try loading new pages into this tab and then navigate forward
and backward through history, noting the events output to the log.</p>
