Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The Document.fullscreen
read-only property reports whether or not the document is currently displaying content in fullscreen mode.
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.
This property is deprecated; test if Document.fullscreenElement
is not null
instead.
Syntax
var isFullScreen = document.fullscreen;
Return value
- A
Boolean
that istrue
if the document is being displayed in fullscreen mode; otherwise it'sfalse
.
Example
function isDocumentInFullScreenMode() { // Better: use fullscreenElement method! return document.fullscreen; }
