HTMLMediaElement: loadeddata event

Baseline Widely available

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.

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

js
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():

js
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:

js
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.",
  );
};
