The ScrollEvent.SCROLL constant defines the value of the
type property of the event object for a scroll event.
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. |
delta | Contains the change in scroll position, expressed in pixels. A positive value indicates the scroll was down or to the right. A negative value indicates the scroll was up or to the left. |
direction | Contains the
scroll direction, either ScrollEventDirection.HORIZONTAL or
ScrollEventDirection.VERTICAL. |
position | Contains the new scroll position. |
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. |
