Element.onfullscreenerror

The Element interface's onfullscreenerror property is an event handler for the fullscreenerror event which is sent to the element when an error occurs while attempting to transition into or out of full-screen mode.

Syntax

targetElement.onfullscreenerror = fullscreenErrorHandler;

Value

An error handler for the fullscreenerror event.

Example

This example attempts to switch into full-screen mode from outside a handler for a user-initiated event (such as a click or keypress event). SInce full-screen mode changes are only permitted in response to a user input, this causes an error to occur, which triggers the delivery of the fullscreenerror event to the error handler,

let elem = document.querySelector("video")}}

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

//....

elem.requestFullscreen();
