isOn参数属性

Retrieves a value that specifies whether the element is active or holding on the timeline in its current state.

dhtml语法

[ bHolding = ] currTimeState.isOn

DHTML可能的值

bHolding Boolean that specifies one of the following values:
true Element is active on the timeline or paused at its end, waiting for the container's timeline to end.
false Default. Element is not active, or is holding on the timeline.
The property is read-only. The property has a default value of false.

Remarks

An element must have the fill attribute set to freeze or hold to enable holding. this property is equivalent to the state property when it returns a value of 4.
an element is considered inactive when it is in a holding state. when an element is inactive, it can neither generate nor respond to events.
