ended event of the MediaStreamTrack interface is fired when playback or streaming has stopped because the end of the media was reached or because no further data is available.

冒泡	No
可取消	No
接口	`事件`
事件处理程序特性	`MediaStreamTrack.onended`

用法注意事项

ended events fire when the media stream track's source permanently stops sending data on the stream. There are various ways this can happen, including:

There is no more data left to send.
The user revoked the permissions needed for the data to be sent.
The hardware generating the source data has been removed or ejected.
A remote peer has permanently stopped sending data; pausing media does not generate an ended 事件。

范例

This example sets up an event handler for the ended event, which changes an on-screen icon to indicate that the track is no longer active.

track.addEventListener('ended', () => {
  let statusElem = document.getElementById("status-icon");
  statusElem.src = "/images/stopped-icon.png";
})

You can also set up the event handler using the MediaStreamTrack.onended 特性：

track.onended = function() {
  let statusElem = document.getElementById("status-icon");
  statusElem.src = "/images/stopped-icon.png";
}
