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'); } }
