The Lock
interface of the Web Locks API provides the name and mode of a lock. This may be a newly requested lock that is received in the callback to LockManager.request()
, or a record of an active or queued lock returned by LockManager.query()
.
The following examples show how the mode and name properties are passed in the call to LockManager.request()
. LockManager
is the object returned by navigator.locks
.
navigator.locks.request("net_db_sync", show_lock_properties);
navigator.locks.request(
"another_lock",
{ mode: "shared" },
show_lock_properties,
);
function show_lock_properties(lock) {
console.log(`The lock name is: ${lock.name}`);
console.log(`The lock mode is: ${lock.mode}`);
}
