MediaSession: playbackState property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The playbackState property of the
MediaSession interface indicates whether the current media session is
playing or paused.
Value
A string indicating the current playback state of the media session. The value may be one of the following:
Example
The following example sets up two functions for playing and pausing, then uses them as
callbacks with the relevant action handlers. Each function harnesses the
playbackState property to indicate whether the audio is playing or paused.
js
const actionHandlers = [
// play
[
"play",
async () => {
// play our audio
await audioEl.play();
// set playback state
navigator.mediaSession.playbackState = "playing";
// update our status element
updateStatus(allMeta[index], "Action: play | Track is playing…");
},
],
[
"pause",
() => {
// pause out audio
audioEl.pause();
// set playback state
navigator.mediaSession.playbackState = "paused";
// update our status element
updateStatus(allMeta[index], "Action: pause | Track has been paused…");
},
],
];
for (const [action, handler] of actionHandlers) {
try {
navigator.mediaSession.setActionHandler(action, handler);
} catch (error) {
console.log(`The media session action "${action}" is not supported yet.`);
}
}
