# AT_TARGET

• AT_TARGET: number

Inherited from ServiceWorkerMessageEvent.AT_TARGET

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5445

# BUBBLING_PHASE

• BUBBLING_PHASE: number

Inherited from ServiceWorkerMessageEvent.BUBBLING_PHASE

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5446

# CAPTURING_PHASE

• CAPTURING_PHASE: number

Inherited from ServiceWorkerMessageEvent.CAPTURING_PHASE

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5447

# Event

• Event: object

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5451

# Type declaration:

new __type(type: string, eventInitDict?: EventInit): Event
AT_TARGET: number
BUBBLING_PHASE: number
CAPTURING_PHASE: number
NONE: number
prototype: Event

# NONE

• NONE: number

Inherited from ServiceWorkerMessageEvent.NONE

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5448

# bubbles

• bubbles: boolean

Inherited from ServiceWorkerMessageEvent.bubbles

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5387

Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.

# cancelBubble

• cancelBubble: boolean

Inherited from ServiceWorkerMessageEvent.cancelBubble

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5388

# cancelable

• cancelable: boolean

Inherited from ServiceWorkerMessageEvent.cancelable

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5392

Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.

# composed

• composed: boolean

Inherited from ServiceWorkerMessageEvent.composed

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5396

Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.

# currentTarget

• currentTarget: EventTarget | null

Inherited from ServiceWorkerMessageEvent.currentTarget

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5400

Returns the object whose event listener's callback is currently being invoked.

# data

• data: any

Defined in packages/workers/src/service-worker.d.ts:6

# defaultPrevented

• defaultPrevented: boolean

Inherited from ServiceWorkerMessageEvent.defaultPrevented

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5404

Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.

# eventPhase

• eventPhase: number

Inherited from ServiceWorkerMessageEvent.eventPhase

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5408

Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.

# isTrusted

• isTrusted: boolean

Inherited from ServiceWorkerMessageEvent.isTrusted

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5412

Returns true if event was dispatched by the user agent, and false otherwise.

# lastEventId

• lastEventId: string

Defined in packages/workers/src/service-worker.d.ts:7

# origin

• origin: string

Defined in packages/workers/src/service-worker.d.ts:8

# ports

• ports: ReadonlyArray‹MessagePort› | null

Defined in packages/workers/src/service-worker.d.ts:9

# returnValue

• returnValue: boolean

Inherited from ServiceWorkerMessageEvent.returnValue

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5413

# source

• source: ServiceWorker | MessagePort | null

Defined in packages/workers/src/service-worker.d.ts:10

# srcElement

• srcElement: EventTarget | null

Inherited from ServiceWorkerMessageEvent.srcElement

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5415

deprecated

# target

• target: EventTarget | null

Inherited from ServiceWorkerMessageEvent.target

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5419

Returns the object to which event is dispatched (its target).

# timeStamp

• timeStamp: number

Inherited from ServiceWorkerMessageEvent.timeStamp

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5423

Returns the event's timestamp as the number of milliseconds measured relative to the time origin.

# type

• type: string

Inherited from ServiceWorkerMessageEvent.type

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5427

Returns the type of event, e.g. "click", "hashchange", or "submit".

# Methods

# composedPath

▸ composedPath(): EventTarget[]

Inherited from ServiceWorkerMessageEvent.composedPath

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5431

Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.

Returns: EventTarget[]

# initEvent

▸ initEvent(type: string, bubbles?: boolean, cancelable?: boolean): void

Inherited from ServiceWorkerMessageEvent.initEvent

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5432

Parameters:

Name	Type
`type`	string
`bubbles?`	boolean
`cancelable?`	boolean

Returns: void

# preventDefault

▸ preventDefault(): void

Inherited from ServiceWorkerMessageEvent.preventDefault

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5436

If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.

Returns: void

# stopImmediatePropagation

▸ stopImmediatePropagation(): void

Inherited from ServiceWorkerMessageEvent.stopImmediatePropagation

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5440

Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.

Returns: void

# stopPropagation

▸ stopPropagation(): void

Inherited from ServiceWorkerMessageEvent.stopPropagation

Defined in node_modules/typedoc/node_modules/typescript/lib/lib.dom.d.ts:5444

When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.

Returns: void
