Document.fullscreenEnabled

The Document.fullscreenEnabled read-only property returns a Boolean that reports whether or not full-screen mode is available. Full screen mode is available only for a page that has no windowed plug-ins in any of its documents, and if all <iframe> elements which contain the document have their allowfullscreen attribute set.

Although this property is read-only, it will not throw if it is modified (even in strict mode); the setter is a no-operation and it will be ignored.

Syntax

var isFullscreenAvailable = document.fullscreenEnabled;

On return, isFullscreenAvailable is true if the document can be put into full-screen mode.

Example

function requestFullScreen() {
  if (document.fullscreenEnabled) {
    videoElement.requestFullScreen();
  } else {
    console.log('Your browser cannot use fullscreen right now');
  }
}
