isOn Property

  • Article

This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.

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

Syntax

[ bHolding = ] currTimeState.isOn

Possible Values

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 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 cannot generate events or respond to events.

Example

This example uses the isOn property to retrieve a value that indicates whether the element is active or holding in its current state.
