Represents a database transaction.

Construction

Transactions are created in the following methods and events:

• Dexie.transaction()
• Dexie.on.populate
• Version.upgrade()

The currently executing transaction is retrieved from Dexie.currentTransaction property.

Properties

active : Boolean

True until transaction is committed or aborted.

db : Dexie

The Dexie instance that created the transaction.

mode : String

“readonly” or “readwrite”

idbtrans : IDBTransaction

Backend transaction instance

tables : Object

Deprecated. See Deprecations Map between table names and Table instances

storeNames : Array

Array of object store names that the Transaction can access. The list depends on which tables were given to Dexie.transaction() when starting the transaction. For upgrade transactions, all object stores will be present in this list.

scopeFunc : Function (optional)

The callback function passed to db.transaction(). For Transactions that has been implicitly created (Not created via db.transaction()), this property will not be set.
