The read-only released
property of the WakeLockSentinel
interface returns a boolean that indicates whether a WakeLockSentinel
has been released yet.
The read-only released
property of the WakeLockSentinel
interface returns a boolean that indicates whether a WakeLockSentinel
has been released yet.
js
const released = sentinel.released
A boolean value, that is false
until the WakeLockSentinel
has been released (either through a call to WakeLockSentinel.release()
or because the lock has been released automatically) and the release
event has been emitted, after which it becomes true
and no longer changes.
This example shows how released
's value changes within a WakeLockSentinel
's life cycle.
js
const sentinel = await navigator.wakeLock.request("screen"); console.log(sentinel.released); // Logs "false" sentinel.onrelease = () => { console.log(sentinel.released); // Logs "true" }; await sentinel.release();
