您好我尝试使用phoneGap Media对象播放音频内容，但我收到此错误未捕获的ReferenceError：媒体未定义我从phonegap文档http://docs.phonegap.com/en/1.0.0/phonegap_media_media.md.html获取此代码示例 enter image description here

当我在浏览器中打开链接而无法播放声音时，提供播放声音的链接无法正常工作。

请将你的rockGuitar.mp3存储在你的assets / www文件夹中，并在播放该文件时提供文件的src

src= "/android_asset/www/rockGuitar.mp3";
newMedia= new Media(src,onSuccess1,onError);

或者在声音的src中提供工作链接。

使用Media对象在设备上录制和播放音频文件
