FetchEvent class

This is the event type for fetch events dispatched on the service worker global scope. It contains information about the fetch, including the request and how the receiver will treat the response. It provides the event.respondWith() method, which allows us to provide a response to this fetch.

Properties

atTarget → num: Available on Event, provided by the Event$Typings extension

no setter
bubbles → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.
no setter
bubblingPhase → num: Available on Event, provided by the Event$Typings extension

no setter
cancelable → bool: Available on Event, provided by the Event$Typings extension
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.

no setter
composed → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
no setter
composedPath ↔ List<EventTarget> Function(): Available on Event, provided by the Event$Typings extension

getter/setter pair
currentTarget → EventTarget?: Available on Event, provided by the Event$Typings extension
Returns the object whose event listener's callback is currently being invoked.
no setter
defaultPrevented → bool: Available on Event, provided by the Event$Typings extension
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
no setter
eventPhase → num: Available on Event, provided by the Event$Typings extension
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
