The Document.hidden
read-only property returns a Boolean value indicating if the page is considered hidden or not.
document.addEventListener("visibilitychange", () => {
console.log(document.hidden);
});
Warning: Due to prerendering, it may happen that document.hidden
is true
, even if the page is actually visible to the user. In such scenario the page load starts with document.visibilityState = "prerender"
and transitions to document.visibilityState = "visible"
after some delay. This scenario can be reproduced by opening a new browser tab in Safari, pasting a URL in the URL bar, and navigating to that URL.
