The events are working only if JavaScript calls the requestFullScreen API, but not if the user presses F11.,I'm trying to monitor when the browser enters fullscreen mode.

The fullscreenchange event is fired immediately after an Element switches into or out of full-screen mode.,Element: fullscreenchange event,In this example, a handler for the fullscreenchange event is added to the element whose ID is fullscreen-div.,Document: fullscreenchange event

 <h1>fullscreenchange event example</h1>
 <div id="fullscreen-div">
    <button id="toggle-fullscreen">Toggle Fullscreen Mode</button>

The 'fullscreenchange' event is not firing on chrome/firefox (probably others too but I haven't tested).,I can confirm this is happening everywhere. Apparently we missed that when refactoring fullscreen.,A knock-on effect, and the reason I noticed, is that the vjs-fullscreen class never gets added because the onFullscreenChange function never gets called., The text was updated successfully, but these errors were encountered:

This does not work in Safari, and the method won’t be called.,Notice here that the W3C approach doesn’t use a hyphen between the word ‘full’ and the word ‘screen’.,The user could, for instance, exit fullscreen, something that might be good for you to know. For that we have a fullscreenchange event, that you can apply both to the element that requested fullscreen, but also to the document. Then we just detect the fullscreen state and take act accordingly, like this:,For security reasons, most keyboard inputs have been blocked in the fullscreen mode. However, in Google Chrome you can request keyboard support by calling the method with a flag:

We now have access to a method called requestFullScreen, so far implemented in Firefox, Google Chrome and Safari. Therefore, to make it work at the moment, we need this code:
