Document.hidden

The Document.hidden read-only property returns a Boolean value indicating if the page is considered hidden or not.

Note: This property is described as "historical" in the Page Visibility Level 2 specification. Consider using the Document.visibilityState property instead.

Syntax

var boolean = document.hidden

Examples

document.addEventListener("visibilitychange", function() {
  console.log( document.hidden );
  // Modify behavior...
});

Usage notes

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.
