IDBFactorySync - Web APIs 编辑

Draft

This page is not complete.

Important: The synchronous version of the IndexedDB API was originally intended for use only with Web Workers, and was eventually removed from the spec because its need was questionable. It may however be reintroduced in the future if there is enough demand from web developers.

The IDBFactorySync interface of the IndexedDB API provide a synchronous means of accessing the capabilities of indexed databases.
