FetchEvent

Boolean that is true if the event was dispatched with the user's intention for the page to reload, and false otherwise. Typically, pressing the refresh button in a browser is a reload, while clicking a link and pressing the back button is not.

The Request that triggered the event handler.

See respondWith page on MDN.

The respondWith() method of the FetchEvent interface is intended for containing code that generates custom responses to the requests coming from the controlled page. This code will resolve by returning a Response or network error to Fetch.

Renderer-side security checks about tainting for cross-origin content are tied to the transparency (or opacity) of the Response body, not URLs. If the request is a top-level navigation and the return value is a Response whose type attribute is opaque (i.e. an opaque response body), a network error is returned to Fetch. The final URL of all successful (non network-error) responses is the requested URL.

A boolean indicating whether the event bubbles up through the DOM or not.

A boolean indicating whether the bubbling of the event has been canceled or not.

A boolean indicating whether the event is cancelable.

Identifies the current target for the event, as the event traverses the DOM. It always refers to the element the event handler has been attached to as opposed to event.target which identifies the element on which the event occurred.

Returns a boolean indicating whether or not event.preventDefault() was called on the event.

Indicates which phase of the event flow is currently being evaluated.

Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)

Cancels the event if it is cancelable, without stopping further propagation of the event.

For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)

Stops the propagation of events further along in the DOM.

This property of event objects is the object the event was dispatched on. It is different than event.currentTarget when the event handler is called in bubbling or capturing phase of the event.

Returns the time (in milliseconds since the epoch) at which the event was created.
