新手求助JS报错：Cannot read property 'play' of undefined

const audios = databus.resources.audios
const scoreList = [
'score1',
'score2',
'score3',
'score4',
'score5',
'score6',
'score7',
'score8',
'score9',
'score10',
'score11',
'score12',
'score13',
'score14',
'score15',
'score16',
'score17',
'score18',
'score19',
'score20',
'score21'
]
var n

playScore() {
scoreList.currentTime = 0,
n = Math.round(Math.random() * 20 + 1);
const bb = scoreList[n]
console.log(bb)
audios.bb.play()
},

bb可以正常打印，把bb改成score1之类的也可以正常播放，为什么用bb就不行？

Answer 1

改成

audios[bb].play()

试试

Answer 2

bb.play()方法中报的错吧，play()里怎么写的

追问

export default {
playScore() {
scoreList.currentTime = 0,
n = Math.round(Math.random() * 20 + 1);
const bb = scoreList[n]
console.log(bb)
audios.bb.play()
},
｝
引用就在场景中直接引用
music.playScore()

追答

你搜索一下，哪里有“.play”的代码，看看对吗

追问

{
key: 'play',
value: function play() {
_innerAudioContext.get(this).play()
}
}
就只剩这里的weapp-adapter.js有一个
