document.mozFullScreenEnabled Redirect 1

« DOM Reference


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.


var isFullScreenAvailable = document.mozFullScreenEnabled;

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



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



See Using full-screen mode for details and examples.
