Examples
Using addEventListener()
:
const videoElement = document.querySelector('video'); videoElement.videoTracks.addEventListener('change', (event) => { console.log(`'${event.type}' event fired`); }); // changing the value of `selected` will trigger the `change` event const toggleTrackButton = document.querySelector('.toggle-track'); toggleTrackButton.addEventListener('click', () => { const track = videoElement.videoTracks[0]; track.selected = !track.selected; });
Using the onchange
event handler property:
const videoElement = document.querySelector('video'); videoElement.videoTracks.onchange = (event) => { console.log(`'${event.type}' event fired`); }; // changing the value of `selected` will trigger the `change` event const toggleTrackButton = document.querySelector('.toggle-track'); toggleTrackButton.addEventListener('click', () => { const track = videoElement.videoTracks[0]; track.selected = !track.selected; });
