无法解决javascript的音频搜索问题

Question

我正在使用HTML和JavaScript制作音频播放器。我也在使用Bootstrap，但是当我想要寻找播放器的音频时，在连接Bootstrap时寻求不起作用。没有Bootstrap寻求工作。请帮我弄清楚如何寻找音频。

这是我的 index.html

var audio, playbtn, mutebtn, seekslider, volumeslider, seeking = false,
  seekto, curtimetext, durtimetext;

function initAudioPlayer() {
  audio = new Audio();
  audio.src = "test.mp3";
  audio.loop = true;
  audio.play();
  // Set object references
  playbtn = document.getElementById("playpausebtn");
  mutebtn = document.getElementById("mutebtn");
  seekslider = document.getElementById("seekslider");
  volumeslider = document.getElementById("volumeslider");
  curtimetext = document.getElementById("curtimetext");
  durtimetext = document.getElementById("durtimetext");
  // Add Event Handling
  playbtn.addEventListener("click", playPause);
  mutebtn.addEventListener("click", mute);
  seekslider.addEventListener("mousedown", function(event) {
    seeking = true;
    seek(event);
  });
  seekslider.addEventListener("mousemove", function(event) {
    seek(event);
  });
  seekslider.addEventListener("mouseup", function() {
    seeking = false;
  });
  volumeslider.addEventListener("mousemove", setvolume);
  audio.addEventListener("timeupdate", function() {
    seektimeupdate();
  });
  // Functions
  function playPause() {
    if (audio.paused) {
      audio.play();

    } else {
      audio.pause();

    }
  }

  function mute() {
    if (audio.muted) {
      audio.muted = false;

    } else {
      audio.muted = true;

    }
  }

  function seek(event) {
    if (seeking) {
      seekslider.value = event.clientX - seekslider.offsetLeft;
      seekto = audio.duration * (seekslider.value / 100);
      audio.currentTime = seekto;
    }
  }

  function setvolume() {
    audio.volume = volumeslider.value / 100;
  }

  function seektimeupdate() {
    var nt = audio.currentTime * (100 / audio.duration);
    seekslider.value = nt;
    var curmins = Math.floor(audio.currentTime / 60);
    var cursecs = Math.floor(audio.currentTime - curmins * 60);
    var durmins = Math.floor(audio.duration / 60);
    var dursecs = Math.floor(audio.duration - durmins * 60);
    if (cursecs < 10) {
      cursecs = "0" + cursecs;
    }
    if (dursecs < 10) {
      dursecs = "0" + dursecs;
    }
    if (curmins < 10) {
      curmins = "0" + curmins;
    }
    if (durmins < 10) {
      durmins = "0" + durmins;
    }
    curtimetext.innerHTML = curmins + ":" + cursecs;
    durtimetext.innerHTML = durmins + ":" + dursecs;
  }
}
window.addEventListener("load", initAudioPlayer);
