How to use audio components to implement music playback function in uniapp

With the popularity of mobile Internet and smart phones, music playback function is becoming more and more common in mobile applications. In uniapp development, we can use the uni-audio component to easily implement the music playback function. This article will introduce in detail how to use audio components in uniapp to implement music playback functions, and provide corresponding code examples.

1. Introducing the uni-audio component
   First, introduce the uni-audio component into the uniapp project. Introduce the path of the uni-audio component in the json file of the page, for example:

"usingComponents": {
  "uni-audio": "/path/to/uni-audio/uni-audio"
}

2. Add audio resources
   In the uniapp project, we need to prepare the audio resources to be played. You can place the audio file in the static directory of the project and save its path to data, for example:

data() {
  return {
    audioUrl: '/static/music.mp3'
  }
}

3. Use the uni-audio component
   In the uniapp page, We can use the uni-audio component to implement the audio playback function. Use the uni-audio component in the template of the page and bind the path of the audio resource, for example:

<uni-audio src="{{ audioUrl }}"></uni-audio>

4. Control audio playback
   Through the uni-audio component, we can easily Control audio playback and pause. Control the audio playback status by calling the component's methods. Add the corresponding control method to the page method, for example:

methods: {
  playAudio() {
    this.$refs.audio.play()
  },
  pauseAudio() {
    this.$refs.audio.pause()
  }
}

5. Add play button
   In order to allow users to control audio playback, we can add play and pause to the page button, and bind the corresponding method, for example:

<button @click="playAudio">播放</button>
<button @click="pauseAudio">暂停</button>

So far, we have completed the steps of using audio components to implement the music playback function in uniapp. Users can control audio playback and pause by clicking buttons.

Complete code example:

<template>
  <view>
    <button @click="playAudio">播放</button>
    <button @click="pauseAudio">暂停</button>
  </view>
</template>

<script>
export default {
  data() {
    return {
      audioUrl: '/static/music.mp3'
    }
  },
  methods: {
    playAudio() {
      this.$refs.audio.play()
    },
    pauseAudio() {
      this.$refs.audio.pause()
    }
  }
}
</script>

<style>
</style>

Through the above steps, we can use the audio component to implement the music playback function in uniapp. Using uni-audio components, we can easily implement audio playback and pause control, and can flexibly expand other audio-related functions. I hope this article will be helpful to you in implementing music playback function in uniapp development.
