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();
