Lock

Lock.mode Read only

Returns the access mode passed to LockManager.request() when the lock was requested. The mode is either "exclusive" (the default) or "shared".

Lock.name Read only

Returns the name passed to LockManager.request() when the lock was requested.

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}`);
}
