Element: fullscreenerror event
{{APIRef("Fullscreen API")}}
The fullscreenerror event is fired when the browser cannot switch to fullscreen mode.
As with the fullscreenchange event, two fullscreenerror events are fired; the first is sent to the {{domxref("Element")}} which failed to change modes, and the second is sent to the {{domxref("Document")}} which owns that element.
For some reasons that switching into fullscreen mode might fail, see the guide to the Fullscreen API.
This event is not cancelable.
Syntax
Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}} , or set an event handler property.
addEventListener("fullscreenerror", (event) => { })
onfullscreenerror = (event) => { }
Event type
A generic {{domxref("Event")}} .
Examples
const requestor = document.querySelector("div");
function handleError(event) {
console.error("an error occurred changing into fullscreen");
console.log(event);
}
requestor.addEventListener("fullscreenerror", handleError);
// or
requestor.onfullscreenerror = handleError;
requestor.requestFullscreen();
