Javascript: webkitIsFullScreen property IE equivalent

Question

According to this documentation, Internet Explorer does not support something like webkitIsFullScreen or like mozFullScreen property. I need to read if browser is in full screen mode. Is there any way to get it on IE somehow? THANKS!

Answer 1

Using IE11, an equivalent check would be:

document.msFullscreenElement !== null
