HTMLMediaElement: canplaythrough event

The canplaythrough event is fired when the user agent can play the media, and estimates that enough data has been loaded to play the media up to its end without having to stop for further buffering of content.

This event is not cancelable and does not bubble.

Syntax

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

addEventListener('canplaythrough', (event) => { });

oncanplaythrough = (event) => { };

Event type

A generic Event.

Examples

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

Using addEventListener():

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

video.addEventListener('canplaythrough', (event) => {
  console.log('I think I can play through the entire ' +
      'video without ever having to stop to buffer.');
});

Using the oncanplaythrough event handler property:

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

video.oncanplaythrough = (event) => {
  console.log('I think I can play through the entire ' +
      'video without ever having to stop to buffer.');
};
