Methods

composedPath() → JSArray<EventTarget>
The composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked. This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode closed.
inherited
initEvent(String type, [bool bubbles, bool cancelable]) → void
The Event.initEvent() method is used to initialize the value of an event created using Document.createEvent.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
preventDefault() → void
The preventDefault() method of the Event interface tells the that if the event does not get explicitly handled, its default action should not be taken as it normally would be.
inherited
stopImmediatePropagation() → void
The stopImmediatePropagation() method of the Event interface prevents other listeners of the same event from being called.
inherited
stopPropagation() → void
The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases. It does not, however, prevent any default behaviors from occurring; for instance, clicks on links are still processed. If you want to stop those behaviors, see the Event.preventDefault method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, see Event.stopImmediatePropagation.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
