How to develop a music player applet?

How to develop a music player applet? The following article will introduce it to you. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

This article follows other people’s examples and makes a music player applet, leaving a footprint. Implement the music player of the following WeChat applet.

The interface is really ugly, first upload the wxss file

//index.wxss
.button-style{ 
background-color: #eee; 
border-radius: 8rpx; 
margin: 20rpx; 
}

It’s just the rounded corners and spacing of a simple button, I still like the color Use the small green primary.

The following is the index.wxml file

//index.wxml

Play

Pause

Set playback progress

Stop playing

Get the playback status

There is no way, using the developer tools to type out this ugly format

The following is the key index. js

//index.js
//获取应用实例
var app = getApp()
Page({
data:{
  },
//播放
listenerButtonPlay:function(){
    wx.playBackgroundAudio({
      dataUrl: \'http://ac-5g9r20ds.clouddn.com/e54ad7f0a834b9c07ec6.mp3\',
      title:\'李宗盛\',
      //图片地址地址
      coverImgUrl:\'http://ac-5g9r20ds.clouddn.com/63bedb5f584234b6827c.jpg\'
    })
  },
  //监听button暂停按钮
  listenerButtonPause:function(){
    wx.pauseBackgroundAudio({
    });
    console.log(\'暂停播放\')
  },
  /**
   * 播放状态
   */
  listenerButtonGetPlayState:function(){
    wx.getBackgroundAudioPlayerState({
      success: function(res){
        // success
        //duration  选定音频的长度（单位：s），只有在当前有音乐播放时返回
        console.log(\'duration:\' + res.duration)
        console.log(\'currentPosition:\' + res.currentPosition)  
        //status    播放状态（2：没有音乐在播放，1：播放中，0：暂停中）
        console.log(\'status:\' + res.status)  
        console.log(\'downloadPercent:\' + res.downloadPercent) 
        //dataUrl   歌曲数据链接，只有在当前有音乐播放时返回 
        console.log(\'dataUrl:\' + res.dataUrl)
      },
      fail: function() {
        // fail
      },
      complete: function() {
        // complete
      }
    })
  },
  /**
   * 设置进度
   */
  listenerButtonSeek:function(){
    wx.seekBackgroundAudio({
      position: 40
    })
  },
  /**
   * 停止播放
   */
  listenerButtonStop:function(){
    wx.stopBackgroundAudio({
    })
    console.log(\'停止播放\')
  },
  onLoad:function(options){
    // 页面初始化 options为页面跳转所带来的参数  
    /** 
     * 监听音乐播放 
     */  
    wx.onBackgroundAudioPlay(function() {
      // callback
      console.log(\'onBackgroundAudioPlay\')
    })
    /**
     * 监听音乐暂停
     */
    wx.onBackgroundAudioPause(function() {
      // callback
      console.log(\'onBackgroundAudioPause\')
    })
    /**
     * 监听音乐停止
     */
    wx.onBackgroundAudioStop(function() {
      // callback
      console.log(\'onBackgroundAudioStop\')
    })
  }
})

You can first look at the onLoad function in order. Three listening functions are defined in it. You can see the effect in the console as shown
