The IndexChangeEvent.CARET_CHANGE constant defines the value of the
type property of the event object for a caretChange event,
which indicates that the current item in focus is about to change.
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
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. |
newIndex | The zero-based index of the selected item after the change. |
oldIndex | The zero-based index of the selected item before the change. |
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. |
