public class IDBTransaction
extends EventTarget

The IDBTransaction interface of the IndexedDB API provides a static, asynchronous transaction on a database using event handler attributes. All reading and writing of data is done within transactions. You use IDBDatabase to start transactions, IDBTransaction to set the mode of the transaction (e.g. is it readonly or readwrite), and you access an IDBObjectStore to make a request. You can also use an IDBTransaction object to abort transactions.

Field Summary

Fields

Modifier and Type	Field and Description
EventHandler	onabort In the following code snippet, we open a read/write transaction on our database and add some data to an object store.
EventHandler	oncomplete The oncomplete event handler of the IDBTransaction interface handles the complete event, fired when the transaction successfully completes.
EventHandler	onerror The onerror event handler of the IDBTransaction interface handles the error event, fired when a request returns an error and bubbles up to the transaction object.

Field Detail

onabort

@Nullable
public EventHandler onabort

In the following code snippet, we open a read/write transaction on our database and add some data to an object store. Note also the functions attached to transaction event handlers to report on the outcome of the transaction opening in the event of success or failure. Note the transaction.onabort = function(event) { }; block, reporting when the transaction has been aborted. For a full working example, see our To-do Notifications app (view example live.)

IDBTransaction.onabort - MDN

oncomplete

@Nullable
public EventHandler oncomplete

The oncomplete event handler of the IDBTransaction interface handles the complete event, fired when the transaction successfully completes.

See Also:

IDBTransaction.oncomplete - MDN

onerror

@Nullable
public EventHandler onerror

The onerror event handler of the IDBTransaction interface handles the error event, fired when a request returns an error and bubbles up to the transaction object.

Method Detail

db

@JsProperty(name="db")
 @Nonnull
public IDBDatabase db()

An IDBDatabase object.

See Also:

IDBTransaction.db - MDN

durability

@JsProperty(name="durability")
 @Nonnull
 @IDBTransactionDurability
public java.lang.String durability()

error

@JsProperty(name="error")
 @Nullable
public DOMException error()

A DOMError containing the relevant error. In Chrome 48+/Firefox 58+ this property returns a DOMException because DOMError has been removed from the DOM standard. The exact error is one of serveral possibilities. It can be a reference to the same error as the request object that raised it, or a transaction failure (for example QuotaExceededError or UnknownError).

IDBTransaction.error - MDN

mode

@JsProperty(name="mode")
 @Nonnull
 @IDBTransactionMode
public java.lang.String mode()

An IDBTransactionMode object defining the mode for isolating access to data in the current object stores:

See Also:

IDBTransaction.mode - MDN

objectStoreNames

@JsProperty(name="objectStoreNames")
 @Nonnull
public DOMStringList objectStoreNames()

The objectStoreNames read-only property of the IDBTransaction interface returns a DOMStringList of names of IDBObjectStore objects.

See Also:

IDBTransaction.objectStoreNames - MDN

abort

public void abort()

The abort() method of the IDBTransaction interface rolls back all the changes to objects in the database associated with this transaction.

See Also:

IDBTransaction.abort - MDN

commit

public void commit()

The commit() method of the IDBTransaction interface commits the transaction if it is called on an active transaction.

See Also:

IDBTransaction.commit - MDN

objectStore

@Nonnull
public IDBObjectStore objectStore(@Nonnull
                                           java.lang.String name)

The objectStore() method of the IDBTransaction interface returns an object store that has already been added to the scope of this transaction.
