前言

这篇文章上一版本是用audio组件开发的播放器，随后反应音频加载速度慢的问题

又用小程序内置的背景音乐播放的方法写了一遍，逻辑是一样的逻辑，希望对大家有所帮助！

<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> <!-- 进度时长 --> <text class='times'>{{duration}}</text> <!-- 总时长 --> </view> </view></view>

js部分注意了：bug ios 播放时必须加title 不然会报错导致音乐不播放

//index.js//获取应用实例const bgMusic = wx.getBackgroundAudioManager()const app = getApp() Page({ data: { isOpen: false,//播放开关 starttime: '00:00', //正在播放时长 duration: '06:41', //总时长 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 播放时必须加title 不然会报错导致音乐不播放 bgMusic.title = '此时此刻' bgMusic.epname = '此时此刻' bgMusic.src = that.data.src; bgMusic.onTimeUpdate(() => { //bgMusic.duration总时长 bgMusic.currentTime当前进度 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; that.setData({ offset: currentTime, starttime: starttime, max: max, changePlay: true }) }) //播放结束 bgMusic.onEnded(() => { that.setData({ starttime: '00:00', isOpen: false, offset: 0 }) console.log("音乐播放结束"); }) bgMusic.play(); that.setData({ isOpen: true, }) }, //暂停播放 listenerButtonPause(){ var that = this bgMusic.pause() that.setData({ isOpen: false, }) }, listenerButtonStop(){ var that = this bgMusic.stop() }, // 进度条拖拽 sliderChange(e) { var that = this var offset = parseInt(e.detail.value); bgMusic.play(); bgMusic.seek(offset); that.setData({ isOpen: true, }) }, // 页面卸载时停止播放 onUnload() { var that = this that.listenerButtonStop()//停止播放 console.log("离开") },})

css部分

/**index.wxss**/.audiosBox{ width: 92%; margin: auto; height: 130rpx; display: flex; justify-content: space-between; align-items: center; background: #f6f7f7; border-radius: 10rpx;}.audioOpen{ width: 70rpx; height: 70rpx; border: 2rpx solid #4c9dee; border-radius: 50%; display: flex; align-items: center; justify-content: center; margin-left: 20rpx;} image{ width: 30rpx; height: 40rpx;}.image2{ margin-left: 10%;}.slid{ flex: 1; position: relative;}.slid view{ display: flex; justify-content: space-between;}.slid view>text:nth-child(1){ color: #4c9dee; margin-left:6rpx; }.slid view>text:nth-child(2){ margin-right:6rpx; }slider{ width: 520rpx; margin: 0; margin-left: 35rpx;}.times{ width: 100rpx; text-align: center; display: inline-block; font-size: 24rpx; color:#999999; margin-top: 5rpx;}.title view{ text-indent: 2em; }
