IDBVersionChangeEvent

« IDBVersionChangeEvent

The IDBVersionChangeEvent interface of the IndexedDB API indicates that the version of the database has changed.

The specification has changed and some not up-to-date browsers only support the deprecated unique attribute, version, from an early draft version.

Properties

IDBVersionChangeEvent.oldVersion Read only
Returns the old version of the database.
IDBVersionChangeEvent.newVersion Read only
Returns the new version of the database.
IDBVersionChangeEvent.version Read only

The new version of the database in a versionchange transaction.

Warning: While this property is still implemented in older browsers, the latest specification replaces it with the oldVersion and newVersion attributes. See the compatibility table to know what browsers support them.

Example

TBD
