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="/UploadFiles/2021-04-02/play.png">
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"
},
// 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; /* 00:00 */
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")
},
})
