The PropertyChangeEvent.PROPERTY_CHANGE
constant defines the value of the
type
property of the event object for a PropertyChange
event.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | Determined by the constructor; defaults to false. |
cancelable | Determined by the constructor; defaults to false. |
kind | The kind of change; PropertyChangeEventKind.UPDATE or PropertyChangeEventKind.DELETE. |
oldValue | The original property value. |
newValue | The new property value, if any. |
property | The property that changed. |
source | The object that contains the property that changed. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
