buzz.sound関数と関数スコープの外で対話する方法は？

Question

function audio(path2audio){ 
    var mySound = new buzz.sound (path2audio, { 
     formats: ["mp3"], 
     preload: false, 
     autoplay: false, 
     loop: false, 
     volume: 70, 
    }); 
    mySound.play(); 
}

Well, I need to make a trigger called outside this function in order to stop the audio file to stop playing. My difficulty is that whenever I call the method outside the function, it shows an error: "main.js:40 Uncaught TypeError: Cannot read property 'bind' of undefined". 

mySound.bind('playing', function() { 
    mySound.stop(); 
}); 

誰かがこれを解決するのに手伝ってもらえますか？

グローバルスコープまたは外部スコープの変数に割り当ててみてください。

var myRealSound; 
function audio(path2audio){ 
    var mySound = new buzz.sound (path2audio, { 
     formats: ["mp3"], 
     preload: false, 
     autoplay: false, 
     loop: false, 
     volume: 70, 
    }); 

    myRealSound = mySound; 

    myRealSound.play(); 
} 


myRealSound.bind('playing', function() { 
    myRealSound.stop(); 
}); 

または...あなたの関数と同じ範囲でイベントバインディングを行います。
