检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

metadata 特性为 MediaSession interface contains a MediaMetadata object  providing descriptive information about the currently playing media, or null if the metadata has not been set. This metadata is provided by the browser to the device for presentation in any standard media control user interface the device might offer.

句法

var mediaMetadata = navigator.mediaSession.metadata;
navigator.mediaSession.metadata = mediaMetadata;
					

实例化的 MediaMetadata containing information about the media currently being played.

范例

The following example creates a new media session and assigns action handlers to it:

if ('mediaSession' in navigator){
  navigator.mediaSession.metadata = new MediaMetadata({
    title: "Podcast Episode Title",
    artist: "Podcast Host",
    album: "Podcast Name",
    artwork: [{src: "podcast.jpg"}]
  });
  navigator.mediaSession.setActionHandler('play', function() {});
  navigator.mediaSession.setActionHandler('pause', function() {});
  navigator.mediaSession.setActionHandler('seekbackward', function() {});
  navigator.mediaSession.setActionHandler('seekforward', function() {});
  navigator.mediaSession.setActionHandler('previoustrack', function() {});
  navigator.mediaSession.setActionHandler('nexttrack', function() {});
}
