- 当前 Bug 的表现（可附上截图）
//index.js

clearInterval(this.timer)
this.timer=setInterval(()=>{
this.setData({

audioContext.pause()
} else {
audioContext.play()

this.setData({
nowplay:!this.data.nowplay
})
},

audioContext.stop()
},
beforesong(){
let index;
if (this.data.nowSong<0){
index = this.data.songs.length-1;
}else{
index = this.data.nowSong-1;
}
this.setData({
nowSong: index
})
audioContext.src=this.data.songs[this.data.nowSong]
},
aftersong(){
let index;
if (this.data.nowSong > this.data.songs.length - 1) {
index = 0;
} else {
index = this.data.nowSong + 1;
}
this.setData({
nowSong: index
})
audioContext.src = this.data.songs[this.data.nowSong]
},
darg(event){
audioContext.seek(event.detail.value * audioContext.duration/100)
this.setData({
persent: event.detail.value
})
},
/**
* 生命周期函数--监听页面加载
*/
onLoad: function(options) {
let that=this;
this.play(this.data.songs[this.data.nowSong])
audioContext.onEnded(function () {
console.log("123")
that.aftersong()
})
},
})




onEnded事件在开发工具上不会触发，但是用手机预览测试可以触发，另外onTimeUpdate事件也不会触发
- 预期表现


- 复现路径


- 提供一个最简复现 Demo
