我是 Android 编程的新手。现在，我正在尝试使用 phonegap 播放声音 onclick。，这是我的完整代码。，

        var sound;
        function playAudio(src) {
            sound = new Media('/android_asset/www/sounds/' + src, onSuccess, onError);
            sound.play();
        }
        function onSuccess() {
            console.log("playAudio():Audio Success");
        }
        function onError(e) {
            alert('code: '    + error.code    + '\n' +
                    'message: ' + error.message + '\n');
        }
    </script>
</head>
<body>
<div data-role="page" id="home">
<div data-role="header">
    <a href="hira_menu.html" data-icon="grid" data-iconpos="notext" data-transition="fade">Upper Menu</a>
    <a href="search.html" data-icon="search" data-iconpos="notext" data-rel="dialog" data-transition="pop">Search</a>

<div data-role="content">

    </div>
</div>
<div data-role="popup" id="a" class="photopopup" data-overlay-theme="a" data-corners="false"
     data-tolerance="30,15">
    <a href="#" data-rel="back" data-role="button" data-theme="a" data-icon="delete" data-iconpos="notext" class="ui-btn-right">Close</a><img src="images/hiragana/a.gif">
    <div align="center">
        <a href="#" onClick="playAudio('aaa.mp3')"><img data-role="button" data-iconpos="notext" src="images/sound.png"/></a>
    </div>
</div>
</div>
</body>
</html>

问题是我有这个错误：

CordovaLog     Uncaught ReferenceError : playAudio is not defined
Web Console    Uncaught ReferenceError : playAudio is not defined at file:///android_asset/www/hira_menu.html : 1

注意：文件 hira_menu.html 是该文件之前的文件。我在这个论坛上搜索了解决方法，但还是不行。，请知道的解决方法...
