范例

On the TextTrack

You can set up a listener for the cuechange event on a TextTrack 使用 addEventListener() 方法：

track.addEventListener('cuechange', function () {
  let cues = track.activeCues;  // array of current cues
});
					

Or you can just set the oncuechange 事件处理程序特性：

track.oncuechange = function () {
  let cues = track.activeCues; // array of current cues
}
					

On the track element

The underlying TextTrack , indicated by the track property, receives a cuechange event every time the currently-presented cue is changed. This happens even if the track isn't associated with a media element.

If the track is associated with a media element, using the <track> element as a child of the <audio> or <video> element, the cuechange event is also sent to the HTMLTrackElement .

let textTrackElem = document.getElementById("texttrack");
textTrackElem.addEventListener("cuechange", (event) => {
  let cues = event.target.track.activeCues;
});
					

In addition, you can use the oncuechange event handler:

let textTrackElem = document.getElementById("texttrack");
textTrackElem.oncuechange = (event) => {
  let cues = event.target.track.activeCues;
});
