ZoomChangeEvent extension type
Properties
- bubbles → bool
-
The
bubbles
read-only property of theEvent
interface indicates whether the event bubbles up through the DOM tree or not.no setterinherited - cancelable → bool
-
The
cancelable
read-only property of theEvent
interface indicates whether the event can be canceled, and therefore prevented as if the event never happened.no setterinherited - cancelBubble ↔ bool
-
The
cancelBubble
property of theEvent
interface is deprecated. UseEvent.stopPropagation
instead. Setting its value totrue
before returning from an event handler prevents propagation of the event. In later implementations, setting this tofalse
does nothing. See Browser compatibility for details.getter/setter pairinherited - composed → bool
-
The read-only
composed
property of theEvent
interface returns a boolean value which indicates whether or not the event will propagate across the shadow DOM boundary into the standard DOM.no setterinherited - currentTarget → EventTarget?
-
The
currentTarget
read-only property of theEvent
interface identifies the element to which the event handler has been attached.no setterinherited - defaultPrevented → bool
-
The
defaultPrevented
read-only property of theEvent
interface returns a boolean value indicating whether or not the call toEvent.preventDefault
canceled the event.no setterinherited - eventPhase → int
-
The
eventPhase
read-only property of theEvent
interface indicates which phase of the event flow is currently being evaluated.no setterinherited - hashCode → int
-
The hash code for this object.
no setterinherited
- isDefinedAndNotNull → bool
-

no setter - isNull → bool
-
Available on JSAny?, provided by the NullableUndefineableJSAnyExtension extension
Whether this value corresponds to JavaScriptnull
.no setter - isTrusted → bool
-
The
isTrusted
read-only property of theEvent
interface is a boolean value that istrue
when the event was generated by the user agent (including via user actions and programmatic methods such asHTMLElement.focus
), andfalse
when the event was dispatched viaEventTarget.dispatchEvent
. The only exception is theclick
event, which initializes theisTrusted
property tofalse
in user agents.no setterinherited - isTruthy → JSBoolean

no setter - returnValue ↔ bool
-
The
Event
propertyreturnValue
indicates whether the default action for this event has been prevented or not.getter/setter pairinherited - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- srcElement → EventTarget?
-
The deprecated
Event.srcElement
is an alias for theEvent.target
property. UseEvent.target
instead.no setterinherited - target → EventTarget?
-
The read-only
target
property of theEvent
interface is a reference to the object onto which the event was dispatched. It is different fromEvent.currentTarget
when the event handler is called during the bubbling or capturing phase of the event.no setterinherited - timeStamp → double
-
The
timeStamp
read-only property of theEvent
interface returns the time (in milliseconds) at which the event was created.no setterinherited - type → String
-
The
type
read-only property of theEvent
interface returns a string containing the event's type. It is set when the event is constructed and is the name commonly used to refer to the specific event, such asclick
,load
, orerror
.no setterinherited

method. It also does not prevent propagation to other event-handlers of the current element. If you want to stop those, seeEvent.stopImmediatePropagation
