HTML 5音频标记多个文件

时间：2013-08-16 13:07:03

标签： html5 html5-audio

我正在尝试将一个HTML 5音频标签中的两个文件一个接一个地播放。我到目前为止的代码是：

<audio id="ListenLive" controls autoplay>
<source src="advert.mp3" type="audio/mpeg">
<source src="stream.mp3" type="audio/mpeg">

</audio>

我目前遇到的问题是只有第一个文件会播放和结束，就像没有第二个文件一样。第一首歌结束后，它就没有别的了。

当第一首曲目结束时，有没有办法让第二首曲目自动播放？我需要它在HTML中，因为它适用于移动网站，因此某些代码可能无法在某些设备上运行

向标记添加多个源不会以这种方式工作。您可以使用它以多种格式提供源。（某些浏览器不支持mp3 - 即Firefox不支持mp3，您应该提供ogg文件）

样品：

<audio>
   <source src="" id="oggSource" type="audio/ogg" />
   <source src="" id="mp3Source" type="audio/mpeg" />
   Your browser does not support the audio element.
</audio>

你的情况不同。您正在尝试制作播放列表。您可以自己制作播放列表：

或者只是使用第三方插件，如：

http://www.jplayer.org/latest/demo-02-jPlayerPlaylist/

使用jPlayer也可以解决浏览器兼容性问题。例如，如果您只提供.mp3格式，当用户使用Firefox浏览时，它将切换到Flash版本。

在javascript中你可以这样做（这只是为了让你入门）：

audio = new Audio("start url");

  audio.addEventListener('ended',function(){
        audio.src = "new url";
        audio.pause();
        audio.load();
        audio.play();
    });

如果你想要你也可以使用同一个播放器（jquery）：

var audio = $("#player");

使用一些javascript你可以做一个技巧

以下是sample，另一个one 

jQuery(function($) {
  var supportsAudio = !!document.createElement('audio').canPlayType;
  if(supportsAudio) {
    var index = 0,
    playing = false;
    mediaPath = 'http://jonhall.info/how_to/assets/media/audio/',
    extension = '',
    tracks = [
      {"track":1,"name":"Happy Birthday Variation: In the style of Beethoven","length":"00:55","file":"01_Happy_Birthday_Variation_In_The"},
      {"track":2,"name":"Wedding March Variation 1","length":"00:37","file":"02_Wedding_March_1"},
      {"track":3,"name":"Happy Birthday Variation: In the style of Tango","length":"01:05","file":"03_Happy_Birthday_Variation_In_The"},
      {"track":4,"name":"Wedding March Variation 2","length":"00:40","file":"04_Wedding_March_2"},
      {"track":5,"name":"Random Classical","length":"00:59","file":"05_AFI_com"}
    ],
    trackCount = tracks.length,
    npAction = $('#npAction'),
    npTitle = $('#npTitle'),
    audio = $('#audio1').bind('play', function() {
      playing = true;
      npAction.text('Now Playing:');
    }).bind('pause', function() {
      playing = false;
      npAction.text('Paused:');
    }).bind('ended', function() {
      npAction.text('Paused:');
      if((index + 1) < trackCount) {
        index++;
        loadTrack(index);
        audio.play();
      } else {
        audio.pause();
        index = 0;
        loadTrack(index);
      }
    }).get(0),
    btnPrev = $('#btnPrev').click(function() {
      if((index - 1) > -1) {
        index--;
        loadTrack(index);
        if(playing) {
          audio.play();
        }
      } else {
        audio.pause();
        index = 0;
        loadTrack(index);
      }
    }),
    btnNext = $('#btnNext').click(function() {
      if((index + 1) < trackCount) {
        index++;
        loadTrack(index);
        if(playing) {
          audio.play();
        }
      } else {
        audio.pause();
        index = 0;
        loadTrack(index);
      }
    }),
    li = $('#plUL li').click(function() {
      var id = parseInt($(this).index());
      if(id !== index) {
        playTrack(id);
      }
    }),
    loadTrack = function(id) {
      $('.plSel').removeClass('plSel');
      $('#plUL li:eq(' + id + ')').addClass('plSel');
      npTitle.text(tracks[id].name);
      index = id;
      audio.src = mediaPath + tracks[id].file + extension;
    },
    playTrack = function(id) {
      loadTrack(id);
      audio.play();
    };

    extension = audio.canPlayType('audio/mpeg') ? '.mp3' : audio.canPlayType('audio/ogg') ? '.ogg' : '';

    loadTrack(index);
  }

  $('#useLegend').click(function(e) {
    e.preventDefault();
    $('#use').slideToggle(300, function() {
      $('#useSpanSpan').text(($('#use').css('display') == 'none' ? 'show' : 'hide'));
    });
  });
});
