dhtml语法

DHTML可能的值

sState String that receives one of the following values.
unknown Timeline is in an unknown state.
active Timeline is active.
cueing Timeline is cueing the media file.
holding Timeline is holding on the current element, waiting for the parent element's timeline to end.
inactive Timeline is inactive.
The property is read-only. The property has no default value.

Remarks

An element is active when it is in either a cueing or seeking state. Note that these two states apply only to elements containing media that can be played, such as an audio or video file.
Elements with the fill attribute set to hold or freeze will wait to synchronize with other elements on the page. an element is inactive when it is in a holding state. when an element is inactive, it can neither generate nor respond to events.
to retrieve the statestring value as an integer, use the state property.
