# Instance Events

Player events are divided into two types: `native events` of the video (prefixed with `video:`), and `custom events`.

Listening to events:

<div className="run-code">▶ Run Code</div>

```js{6}
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
});

art.on('video:canplay', () => {
    console.info('video:canplay');
});
```

Listening to an event only once:

<div className="run-code">▶ Run Code</div>

```js{6}
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
});

art.once('video:canplay', () => {
    console.info('video:canplay');
});
```

Manually triggering an event:

<div className="run-code">▶ Run Code</div>

```js{6}
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
});

art.emit('focus');
```

Removing an event:

<div className="run-code">▶ Run Code</div>

```js{8}
var art = new Artplayer({
    container: '.artplayer-app',
    url: '/assets/sample/video.mp4',
});

const onReady = () => {
    console.info('ready');
    art.off('ready', onReady);
}

art.on('ready', onReady);
```
