The leavepictureinpicture event is fired when the HTMLVideoElement leaves picture-in-picture mode successfully.

This event is not cancelable and does not bubble.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('leavepictureinpicture', event => { });

onleavepictureinpicture = event => { };

Event properties

This interface also inherits properties from its parent Event.

Examples

These examples add an event listener for the HTMLVideoElement's leavepictureinpicture event, then post a message when that event handler has reacted to the event firing.

Using addEventListener():

const video = document.querySelector('#video');
const button = document.querySelector('#button');

function onExitPip() {
  console.log("Picture-in-Picture mode deactivated!");
}

video.addEventListener("leavepictureinpicture", onExitPip, false);

button.onclick = function() => {
  if (document.pictureInPictureElement) {
    document.exitPictureInPicture();
  }
}

Using the onleavepictureinpicture event handler property:

const video = document.querySelector('#video');
const button = document.querySelector('#button');

function onExitPip() {
  console.log("Picture-in-Picture mode deactivated!");
}

video.onleavepictureinpicture = onExitPip;

button.onclick = function() => {
  if (document.pictureInPictureElement) {
    document.exitPictureInPicture();
  }
}
