IDBDatabase.onclose
The onclose event handler of the
IDBDatabase interface handles the close event, which is
fired when the database is unexpectedly closed. This can happen, for example, when the
application is shut down or access to the disk the database is stored on is lost while
the database is open.
The close event is fired after all transactions have been aborted and
the connection has been closed.
Note: This feature is available in Web Workers.

A function which is called when the close event is fired.

db.onclose = function(event) {
myAppShowAlert('The database "' + db.name + '" has unexpectedly closed.');
