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

cancelBubble ↔ bool

Available on Event, provided by the Event$Typings extension

@deprecated

getter/setter pair

capturingPhase → num

Available on Event, provided by the Event$Typings extension

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.

no setter

hashCode → int

The hash code for this object.

no setter, inherited

initEvent ↔ void Function(String, [bool?, bool?])

Available on Event, provided by the Event$Typings extension

getter/setter pair

isTrusted → bool

Available on Event, provided by the Event$Typings extension

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

no setter

none → num

Available on Event, provided by the Event$Typings extension

no setter

preventDefault ↔ void Function()

Available on Event, provided by the Event$Typings extension

getter/setter pair

returnValue ↔ bool

Available on Event, provided by the Event$Typings extension

runtimeType → Type

A representation of the runtime type of the object.

target → EventTarget?

Available on Event, provided by the Event$Typings extension

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

no setter

timeStamp → num

Available on Event, provided by the Event$Typings extension

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

no setter

type → String

Available on Event, provided by the Event$Typings extension

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

no setter
