Summary

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 mozallowfullscreen attribute set.

Syntax

var isFullScreenAvailable = document.mozFullScreenEnabled;

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

Example

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

Notes
