如何为具有不同音频src的多个onclick图像添加播放/暂停切换

标签： javascript html5

我有多个具有onclick功能的图像，可以为每个单独的图像播放不同的音频源。但是，我还想要一个切换或播放/暂停功能，如果再次点击同一图像，音频会暂停。

我曾尝试合并.pause（）和切换功能，但我不能让它正常工作。在这种情况下，你们有任何想法和建议如何使用暂停和/或切换功能吗？

这是我的fiddle

＆＃13;
＆＃13; 
var aAudio = new Audio('a.mp3');
var bAudio = new Audio('b.mp3');
var cAudio = new Audio('c.mp3');

function myAudioFunction(letter) {
  if (letter == 'a') {
    aAudio.play();
  } else if (letter == 'b') {
    bAudio.play();
  } else if (letter == 'c') {
    cAudio.play();
  }
}
＆＃13;

您可以使用paused属性与currentTime属性相结合来判断按下按钮时是否需要暂停或播放音频元素。

function myAudioFunction(letter) {
  var players = {
    a: aAudio,
    b: bAudio,
    c: cAudio
  };

  var player = players[letter];

  if (player.currentTime == 0 || player.paused) {
    player.play();
  } else {
    player.pause();
  }
}

您可以通过检查其paused属性来检查音频是否正在播放。您还必须检查音频是否从未启动，您可以使用currentTime属性执行此操作。

以下是一个例子：

var aAudio = new Audio('a.mp3');
var bAudio = new Audio('b.mp3');
var cAudio = new Audio('c.mp3');

function myAudioFunction(letter) {
  toggleAudio(window[letter+"Audio"]);
}

function toggleAudio(audioElm){
   if(!audioElm.currentTime || audioElm.paused){
       audioElm.play();
   }else{
       audioElm.pause();
   }
}

有几种方法可以做到这一点！使用paused属性

var audiolinks = document.querySelectorAll("a");

//loop over all links | audiolinks is a nodelist without forEach - use Array's forEach
Array.prototype.forEach.call(audiolinks, function(element, index) {
  element.addEventListener("click", function() {
    myAudioFunction(index);
  })
});

var aAudio = new Audio('a.mp3');
var bAudio = new Audio('b.mp3');
var cAudio = new Audio('c.mp3');
var audioPlaying = "|"; //use | to avoid selecting Audio element

function myAudioFunction(index) {
  res = String.fromCharCode(97 + index);
  //select char (a, b, etc.) and use bracket to combine it with audio.
  if (window[audioPlaying + "Audio"]) {
    if (!window[audioPlaying + "Audio"].paused && res == audioPlaying) {
      console.log("pause", audioPlaying);
      window[audioPlaying + "Audio"].pause();
    } else if (!window[audioPlaying + "Audio"].paused && res != audioPlaying) {
      console.log("stop", audioPlaying);
      window[audioPlaying + "Audio"].pause();

      window[audioPlaying + "Audio"].currentTime = 0;
    } else {
      console.log("play", audioPlaying);
      window[audioPlaying + "Audio"].play();
    }

  }

  //if res isn't audioPlaying, start the audio
  if (res != audioPlaying) {
    console.log("play", res);
    window[res + "Audio"].play();
    audioPlaying = res;
  }
}
