The prerenderingchange event is fired on a prerendered document when it is activated (i.e. the user views the page).

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("prerenderingchange", (event) => {});

prerenderingchange = (event) => {};

A generic Event.

The following code sets up an event listener to run a function once prerendering has finished, on a prerendered page (the prerendering is detected via Document.prerendering), or runs it immediately on a non-prerendered page:

if (document.prerendering) {
  document.addEventListener("prerenderingchange", initAnalytics, {
    once: true,
  });
} else {
  initAnalytics();
}
