这是一个普通的音频播放器，但如果我想我的来源是音频存储在我的数据库中，我将如何去实现这一点？

<audio controls="controls" autoplay="true" loop="loop">
<source src="WhiteChristmas.mp3"/>
</audio>

这就是我目前使用WebService从数据库中阅读音频文件的方式。

[WebMethod]
    public void PlayXhosa(int id)
    {

        using (The_FactoryDBContext db = new The_FactoryDBContext())
        {
            if (db.Words.FirstOrDefault(word => word.wordID == id).xhosaAudio != null)
            {
                byte[] bytes = db.Words.FirstOrDefault(word => word.wordID == id).xhosaAudio;

                MemoryStream ms = new MemoryStream(bytes);
                System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(ms);
                myPlayer.Play();
            }
        }

    }

这就是我的客户端代码目前的样子

function PlayXhosa() {
                var id = $("[id$=hiddenWord_id]").val();
                $.ajax({

                    url: "../../WebService.asmx/PlayXhosa",
                    data: "{ 'id': '" + id + "'}",
                    dataType: "json",
                    type: "POST",
                    contentType: "application/json; charset=utf-8",
                    success: function (data) {
                    },
                    error: function (XMLHttpRequest, textStatus, errorThrown) {

                    }
                });
            };

然后我尝试像这样调用这个函数：

var audio = document.createElement('audio');
 audio.autoplay = false;
 audio.oncanplaythrough = function() {
 foo.disabled = false;
    };
   audio.src = 'PlayXhosa()';
   foo.onclick = function() {
     audio.play();

}
然后是按钮。

<button id="foo" disabled>play xhosa audio</button>
