HTMLMediaElement: loadeddata event - Web APIs 编辑

The loadeddata event is fired when the frame at the current playback position of the media has finished loading; often the first frame.

Note that this event will not fire in mobile/tablet devices if data-saver is on in browser settings.

Examples

These examples add an event listener for the HTMLMediaElement's loadeddata event, then post a message when that event handler has reacted to the event firing.

Using addEventListener():

const video = document.querySelector('video');

video.addEventListener('loadeddata', (event) => {
  console.log('Yay! The readyState just increased to  ' +
      'HAVE_CURRENT_DATA or greater for the first time.');
});

Using the onloadeddata event handler property:

const video = document.querySelector('video');

video.onloadeddata = (event) => {
  console.log('Yay! The readyState just increased to  ' +
      'HAVE_CURRENT_DATA or greater for the first time.');
};
