# 实例事件

播放器的事件分为两种，一种视频的 `原生事件` (前缀 `video:`)，另外一种是 `自定义事件`

监听事件：

<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');
});
```

只监听一次事件：

<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');
});
```

手动触发事件：

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

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

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

移除事件：

<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);
```
