HTML5音頻標籤停止按鈕，停止一個實時MP3流？

Question

我想添加一個停止按鈕。此刻只有一個播放和暫停按鈕，但該停止並不是真正的瀏覽器緩衝音樂，但不會跳到開始。使用MP3文件也許是可以的，但不是在直播中。有人能幫我嗎？謝謝。

var pause = new Image(); 
pause.src = "pause.png"; 

var play_control = 0; 
function playmusic() { 
    if (play_control == 0) { 
     document.getElementById('musikplayer').play(); 
     document.getElementById('playbutt').src = 'pause.png'; 
     play_control = 1; 
     window.setTimeout("playcontrol()", 0); 
     window.setTimeout("zeitanzeige()", 0); 
    } else { 
     document.getElementById('musikplayer').pause(); 
     document.getElementById('playbutt').src = 'play.png'; 
     play_control = 0; 
    } 
} 
function playcontrol() { 
    if(play_control == 1) { 
     if(
      document.getElementById('musikplayer').currentTime 
      == document.getElementById('musikplayer').duration 
     ) { 
      document.getElementById('playbutt').src = 'play.png'; 
      play_control = 0; 
     } else { 
      window.setTimeout("playcontrol()",0); 
     } 
    } 
} 
function zeitanzeige() { 
    if(play_control == 1) { 
     var full = document.getElementById('musikplayer').duration; 
     var full_min = Math.floor(full/60); 
     var full_sec = Math.floor(full - (full_min * 60)); 

     if(full_min < 10) { 
      full_min = '0' + full_min;

如果您只需要一個停止按鈕，則不會通過JavaScript API直接控制這樣的事情。但是，基本上可以通過暫停歌曲並將其設置爲從一開始播放（假設您不想停止緩衝）來模擬相同的行爲。類似這樣的：

var stop = function(stopButtonAudio) { 
    stopButtonAudio.pause(); 
    stopButtonAudio.currentTime=0; 
}
