前言 

這篇文章上一版本是用audio元件開發的播放器,隨後反應音訊載入速度慢的問題

又用小程式內建的背景音樂播放的方法寫了一遍,邏輯是一樣的邏輯,希望對大家有所幫助！

<view class='audiosBox'>
    <view class="audioOpen" bindtap="listenerButtonPlay" wx:if="{{!isOpen}}">
      <image class='image2' src="../../images/play.png" />
    </view>
    <view class="audioOpen" bindtap="listenerButtonPause" wx:if="{{isOpen}}">
      <image src="../../images/pauses.png" />
    </view>
    <view class='slid'>
      <slider bindchange="sliderChange"  block-size="12px" step="2" value="{{offset}}" max="{{max}}" selected-color="#4c9dee" />
      <view>
        <text class='times'>{{starttime}}</text> <!-- 進度時長 -->
       
        <text class='times'>{{duration}}</text>   <!-- 總時長 -->
      </view>
    </view>
</view>
 

js部分注意了：bug ios 播放時必須加title 不然會報錯導致音樂不播放

//index.js
//獲取應用例項
const bgMusic = wx.getBackgroundAudioManager()
const app = getApp()

Page({
  data: {
    isOpen: false,//播放開關
    starttime: '00:00', //正在播放時長
    duration: '06:41',   //總時長
    src:"http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guid=ffffffff82def4af4b12b3cd9337d5e7&uin=346897220&vkey=6292F51E1E384E061FF02C31F716658E5C81F5594D561F2E88B854E81CAAB7806D5E4F103E55D33C16F3FAC506D1AB172DE8600B37E43FAD&fromtag=46"
  },
  // 播放
  listenerButtonPlay: function () {
    var that = this
    //bug ios 播放時必須加title 不然會報錯導致音樂不播放
    bgMusic.title = '此時此刻'  
    bgMusic.epname = '此時此刻'
    bgMusic.src = that.data.src;
    bgMusic.onTimeUpdate(() => { 
      //bgMusic.duration總時長  bgMusic.currentTime當前進度
      console.log(bgMusic.currentTime)
      var duration = bgMusic.duration; 
      var offset = bgMusic.currentTime;  
      var currentTime = parseInt(bgMusic.currentTime);
      var min = "0" + parseInt(currentTime / 60);
      var max = parseInt(bgMusic.duration);
      var sec = currentTime % 60;
      if (sec < 10) {
        sec = "0" + sec;
      };
      var starttime = min + ':' + sec;   /*  00:00  */
      that.setData({
        offset: currentTime,
        starttime: starttime,
        max: max,
        changePlay: true
      })
    })
    //播放結束
    bgMusic.onEnded(() => {
      that.setData({
        starttime: '00:00',
        isOpen: false,
        offset: 0
      })
      console.log("音樂播放結束");
    })
    bgMusic.play();
    that.setData({
      isOpen: true,
    })
  },
  //暫停播放
  listenerButtonPause(){
     var that = this
    bgMusic.pause()
    that.setData({
      isOpen: false,
    })
  },
  listenerButtonStop(){
    var that = this
    bgMusic.stop()
  },
  // 進度條拖拽
  sliderChange(e) {
    var that = this
    var offset = parseInt(e.detail.value);
    bgMusic.play();
    bgMusic.seek(offset);
    that.setData({
      isOpen: true,
    })
  },
  // 頁面解除安裝時停止播放
  onUnload() {
    var that = this
    that.listenerButtonStop()//停止播放
    console.log("離開")
  },
})
