实现音乐播放功能的基本步骤

在Vue中实现音乐播放功能，可以通过HTML5的<audio>标签或第三方库如howler.js来完成。以下是两种方法的详细说明。

使用HTML5 `<audio>`标签

通过Vue绑定<audio>标签的属性和事件，可以轻松实现音乐播放功能。

模板部分

<template>
  <div>
    <audio ref="audioPlayer" :src="currentSong.url"></audio>
    <button @click="togglePlay">{{ isPlaying ? '暂停' : '播放' }}</button>
    <input type="range" v-model="currentTime" @input="seek" min="0" :max="duration">
    <span>{{ formatTime(currentTime) }} / {{ formatTime(duration) }}</span>
  </div>
</template>

脚本部分

<script>
export default {
  data() {
    return {
      currentSong: {
        url: 'path/to/music.mp3'
      },
      isPlaying: false,
      currentTime: 0,
      duration: 0
    }
  },
  mounted() {
    const audio = this.$refs.audioPlayer;
    audio.addEventListener('timeupdate', this.updateTime);
    audio.addEventListener('loadedmetadata', this.updateDuration);
    audio.addEventListener('ended', this.onEnded);
  },
  methods: {
    togglePlay() {
      const audio = this.$refs.audioPlayer;
      if (this.isPlaying) {
        audio.pause();
      } else {
        audio.play();
      }
      this.isPlaying = !this.isPlaying;
    },
    updateTime() {
      this.currentTime = this.$refs.audioPlayer.currentTime;
    },
    updateDuration() {
      this.duration = this.$refs.audioPlayer.duration;
    },
    seek() {
      this.$refs.audioPlayer.currentTime = this.currentTime;
    },
    onEnded() {
      this.isPlaying = false;
    },
    formatTime(seconds) {
      const minutes = Math.floor(seconds / 60);
      const secs = Math.floor(seconds % 60);
      return `${minutes}:${secs < 10 ? '0' : ''}${secs}`;
    }
  }
}
</script>

使用howler.js库

howler.js是一个功能强大的音频库，适合处理更复杂的音频需求。

安装howler.js

npm install howler

实现代码

<script>
import { Howl } from 'howler';

export default {
  data() {
    return {
      sound: null,
      isPlaying: false,
      currentTime: 0,
      duration: 0
    }
  },
  mounted() {
    this.sound = new Howl({
      src: ['path/to/music.mp3'],
      html5: true,
      onplay: () => {
        this.isPlaying = true;
        this.updateDuration();
        requestAnimationFrame(this.updateTime);
      },
      onpause: () => {
        this.isPlaying = false;
      },
      onend: () => {
        this.isPlaying = false;
      }
    });
  },
  methods: {
    togglePlay() {
      if (this.isPlaying) {
        this.sound.pause();
      } else {
        this.sound.play();
      }
    },
    updateTime() {
      this.currentTime = this.sound.seek();
      if (this.isPlaying) {
        requestAnimationFrame(this.updateTime);
      }
    },
    updateDuration() {
      this.duration = this.sound.duration();
    },
    seek() {
      this.sound.seek(this.currentTime);
    },
    formatTime(seconds) {
      const minutes = Math.floor(seconds / 60);
      const secs = Math.floor(seconds % 60);
      return `${minutes}:${secs < 10 ? '0' : ''}${secs}`;
    }
  }
}
</script>
