Document: visibilityState property

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.

hidden

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

js
document.addEventListener("visibilitychange", () => {
  console.log(document.visibilityState);
  // Modify behavior…
});
