Document.onfullscreenerror

The Document.onfullscreenerror property is an event handler for the fullscreenerror event that is sent to the  document when it fails to transition into full-screen mode after a prior call to Element.requestFullscreen().

Syntax

targetDocument.onfullscreenerror = fullscreenErrorHandler;

Value

An event handler for the fullscreenerror event.

Example

This example attempts to call requestFullscreen() outside of an event handler. Since requestFullscreen() can only be called in response to user action, for security reasons, this will fail, causing the fullscreenerror to be sent to the document.

document.onfullscreenerror = function ( event ) {
  displayWarning("Unable to switch into full-screen mode.");
};

//....

document.documentElement.requestFullscreen();
