Question

我从不使用这种语言，只帮助一个朋友。我正在尝试播放一个字的声音。但是执行速度很快。

audio.vue

methods: {
    .then(setTimeout(() => {
      const arr = 'test'
      Array.prototype.forEach.call(arr, char => {
        audio.playChar(char) //Passing each char separately, wait 1 second before execure next iterator
      })
    }, 
    ...
  }
}

audio.js

 playTest (char) {
    return new Promise((resolve, reject) => {
      const audio = new Audio()
      audio.src = `.../alert/pt/${char}.mp3` //playing separately but very quickly
      audio.onended = resolve
      audio.onerror = reject
      audio.play()
    })
  },

如果要延迟每次执行该函数，请在该函数之后的setTimeout中添加一个整数。

audio.vue：

methods: {
    .then(setTimeout(() => {
      const arr = 'test'
      Array.prototype.forEach.call(arr, char => {
        audio.playChar(char) //Passing each char separately, wait 1 second before execure next iterator
      })
    }, 1000 //<== add 1000 milliseconds to your setTimeout
    ...
  }
}
