This feature is well established and works across many devices and browser versions. It’s been available across browsers since ⁨July 2015⁩.

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

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

addEventListener("loadeddata", (event) => { })  onloadeddata = (event) => { }

Event type

A generic Event.

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.",   ); };
