Locks.mode

The mode read-only property of the Lock interface returns the access mode passed to LockManager.request() when the lock was requested. The mode is either "exclusive" (the default) or "shared".

Syntax

var mode = Lock.mode

Value

One of "exclusive" or "shared".

Example

The following examples show how the mode property is passed in the call to LockManager.request(). LockManager is the object returned by navigator.locks.

// Should show "exclusive" (the default)
navigator.locks.request("my_resource", show_lock_properties);

// Should show "exclusive"
navigator.locks.request("my_resource", {mode: "exclusive"}, show_lock_properties);

// Should show "shared"
navigator.locks.request("my_resource", {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}`);
}
