How to use audio and video API to implement media playback in Vue

Vue is a popular JavaScript framework that provides a wealth of tools and APIs, allowing developers to easily develop high-quality web applications. Among them, Vue also provides audio and video APIs, allowing developers to easily implement media playback functions.

This article will introduce how to use the audio and video API in Vue to implement media playback functions.

1. Audio and video API in Vue

Vue provides two media APIs: Audio and Video. Both Audio and Video objects can be used by creating Vue instances. Here are some basic examples:

1. Create a Vue instance

new Vue({
  el: '#app',
  data: {
    audio: null,
    video: null
  },
  mounted() {
    this.audio = new Audio('audio.mp3');
    this.video = new Video('video.mp4');
  }
})

2. Play audio

this.audio.play();

3. Pause audio

this.audio.pause();

4. Play video

this.video.play();

5. Pause video

this.video.pause();

2. Use Vue to implement media playback

The following is a simple example that demonstrates how to use the audio and video API in Vue Implement media playback function.

1. Create a Vue instance

new Vue({
  el: '#app',
  data: {
    audio: null,
    video: null,
    isPlaying: false
  },
  mounted() {
    this.audio = new Audio('audio.mp3');
    this.video = new Video('video.mp4');
  },
  methods: {
    playPause() {
      if (this.isPlaying) {
        if (this.audio) this.audio.pause();
        if (this.video) this.video.pause();
      } else {
        if (this.audio) this.audio.play();
        if (this.video) this.video.play();
      }
      this.isPlaying = !this.isPlaying;
    }
  }
})

2. Add HTML template

<div id="app">
  <button @click="playPause">{{isPlaying ? 'Pause' : 'Play'}}</button>
</div>

3. Run the application

You can now run the application and play audio and video. Click the "Play" button to start playing, click the "Pause" button to pause playing.

Summary:

Vue’s audio and video API is very simple and easy to use, and the media playback function can be realized with a few lines of code. In actual applications, you can integrate these APIs with other Vue functions as needed to implement more complex applications.
