Document: visibilityState property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Document.visibilityState
read-only property returns the visibility of the document. It can be used to check whether the document is in the background or in a minimized window, or is otherwise not visible to the user.
When the value of this property changes, the visibilitychange event is sent to the Document.
The Document.hidden property provides an alternative way to determine whether the page is hidden.
Value
A string with one of the following values:
visible-
The page content may be at least partially visible. In practice this means that the page is the foreground tab of a non-minimized window.
-
The page content is not visible to the user. In practice this means that the document is either a background tab or part of a minimized window, or the OS screen lock is active.
Examples
document.addEventListener("visibilitychange", () => {
console.log(document.visibilityState);
// Modify behavior…
});
