The TextTrackCue interface of the WebVTT API is the abstract base class for the various derived cue types, such as VTTCue; you will work with these derived types rather than the base class.

实例属性

These cues represent strings of text presented for some duration of time during the performance of a TextTrack. The cue includes the start time (the time at which the text will be displayed) and the end time (the time at which it will be removed from the display), as well as other information.

This interface also inherits properties from EventTarget.: TextTrackCue.track 只读
The TextTrack that this cue belongs to, or null if it doesn't belong to any.: TextTrackCue.id
A string that identifies the cue.: TextTrackCue.startTime
A double that represents the video time that the cue will start being displayed, in seconds.: TextTrackCue.endTime
A double that represents the video time that the cue will stop being displayed, in seconds.: TextTrackCue.pauseOnExit

事件
