IndexedDB是否支持类似SQL的事务？

Question

I am trying to understand IndexedDB using the docs at MDN .

I'm still not clear if it supports SQL-like transactions with rollbacks.

Answer 1

Yes it does.

IndexedDB is built on a transactional database model. Everything you do in IndexedDB always happens in the context of a transaction. The IndexedDB API provides lots of objects that represent indexes, tables, cursors, and so on, but each of these is tied to a particular transaction. Thus, you cannot execute commands or open cursors outside of a transaction.
