The loadedmetadata event is fired when the metadata has been loaded.

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

addEventListener("loadedmetadata", (event) => {});

onloadedmetadata = (event) => {};

A generic Event.

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():

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:

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

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