Examples

These examples add an event listener for the HTMLMediaElement's loadedmetadata 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("loadedmetadata", (event) => {
  console.log(
    "The duration and dimensions of the media and tracks are now known.",
  );
});

Using the onloadedmetadata event handler property:

js
const video = document.querySelector("video");

video.onloadedmetadata = (event) => {
  console.log(
    "The duration and dimensions of the media and tracks are now known.",
  );
};
