Event Interface / dart:html Library / Dart API Reference

Event Interface

This chapter describes the DOM Event Model. The Event interface itself is described, as well as the interfaces for event registration on nodes in the DOM, and event listeners, and several longer examples that show how the various event interfaces relate to one another.

There is an excellent diagram that clearly explains the three phases of event flow through the DOM in the DOM Level 3 Events draft.

Methods

Code void preventDefault() #

Cancels the event (if it is cancelable).

from MDN

void preventDefault();

Code void stopImmediatePropagation() #

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)

from MDN

void stopImmediatePropagation();

Code void stopPropagation() #

Stops the propagation of events further along in the DOM.

from MDN

void stopPropagation();

Code void $dom_initEvent(String eventTypeArg, bool canBubbleArg, bool cancelableArg) #

Initializes the value of an Event created through the DocumentEvent interface.

from MDN

void $dom_initEvent(String eventTypeArg, bool canBubbleArg, bool cancelableArg);

Fields

Code final bool bubbles #

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

from MDN

final bool bubbles;

Code bool cancelBubble #

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

from MDN

bool cancelBubble;

Code final bool cancelable #

A boolean indicating whether the event is cancelable.

from MDN

final bool cancelable;

Code final Clipboard clipboardData #

final Clipboard clipboardData;

Code final EventTarget currentTarget #

A reference to the currently registered target for the event.

from MDN

final EventTarget currentTarget;

Code final bool defaultPrevented #

Indicates whether or not event.preventDefault() has been called on the event.

from MDN

final bool defaultPrevented;

Code final int eventPhase #

Indicates which phase of the event flow is being processed.

from MDN

final int eventPhase;

Code bool returnValue #

bool returnValue;

Code final EventTarget srcElement #

final EventTarget srcElement;

Code final EventTarget target #

A reference to the target to which the event was originally dispatched.

from MDN

final EventTarget target;

Code final int timeStamp #

The time that the event was created.

from MDN

final int timeStamp;

Code final String type #

The name of the event (case-insensitive).

from MDN

final String type;
