StorageEvent

Represents the key changed. The key attribute is null when the change is caused by the storage clear() method. Read only.

The new value of the key. The newValue is null when the change has been invoked by storage clear() method or the key has been removed from the storage. Read only.

The original value of the key. The oldValue is null when the change has been invoked by storage clear() method or the key has been newly added and therefor doesn't have any previous value. Read only.

Represents the Storage object that was affected. Read only.

The URL of the document whose key changed. Read only.

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.

Indicates whether or not the event will propagate across the shadow DOM boundary into the standard DOM.

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.
