Properties

Readonlydb

db: IDBDatabase

Returns the transaction's connection.

MDN Reference

Readonlydurability

durability: IDBTransactionDurability

MDN Reference

Readonlyerror

error: null | DOMException

If the transaction was aborted, returns the error (a DOMException) providing the reason.

MDN Reference

Readonlymode

mode: IDBTransactionMode

Returns the mode the transaction was created with ("readonly" or "readwrite"), or "versionchange" for an upgrade transaction.

MDN Reference

ReadonlyobjectStoreNames

objectStoreNames: DOMStringList

Returns a list of the names of object stores in the transaction's scope. For an upgrade transaction this is all object stores in the database.

onabort

onabort: null | ((this: IDBTransaction, ev: Event) => any)

Methods

abort

  • abort(): void

  • Aborts the transaction. All pending requests will fail with a "AbortError" DOMException and all changes made to the database will be reverted.

    MDN Reference

    Returns void

addEventListener

  • addEventListener<K>(type, listener, options?): void

  • Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

    The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

    When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

    When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

    When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

    If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

    The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.

    Type Parameters

    Parameters

    Returns void

  • addEventListener(type, listener, options?): void

  • Appends an event listener for events whose type attribute value is type. The callback argument sets the callback that will be invoked when the event is dispatched.

    The options argument sets listener-specific options. For compatibility this can be a boolean, in which case the method behaves exactly as if the value was specified as options's capture.

    When set to true, options's capture prevents callback from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE. When false (or not present), callback will not be invoked when event's eventPhase attribute value is CAPTURING_PHASE. Either way, callback will be invoked if event's eventPhase attribute value is AT_TARGET.

    When set to true, options's passive indicates that the callback will not cancel the event by invoking preventDefault(). This is used to enable performance optimizations described in § 2.8 Observing event listeners.

    When set to true, options's once indicates that the callback will only be invoked once after which the event listener will be removed.

    If an AbortSignal is passed for options's signal, then the event listener will be removed when signal is aborted.

    The event listener is appended to target's event listener list and is not appended if it has the same type, callback, and capture.

    Returns void

commit

  • commit(): void

  • MDN Reference

    Returns void

dispatchEvent

  • dispatchEvent(event): boolean

  • Dispatches a synthetic event event to target and returns true if either event's cancelable attribute value is false or its preventDefault() method was not invoked, and false otherwise.

removeEventListener

  • removeEventListener<K>(type, listener, options?): void
