I am building an app with extensive audio requirements, so I am using SoundJS for that, and I am compiling the app using phonegap.
(我正在构建具有广泛音频要求的应用程序，因此我为此使用了SoundJS，并使用phonegap编译了该应用程序。)
I am using the mobile safe approach to build a soundJS app.
(我正在使用移动安全方法来构建soundJS应用。)
It seems that there are different audio plugins , including a special Cordova audio plugin.(似乎有不同的音频插件 ，包括特殊的Cordova音频插件。)
So, I am not able to register any of these plugins on the compiled app.(因此，我无法在已编译的应用程序中注册任何这些插件。)
This is because registering any plugin requires to check if this plugin is supported or not.(这是因为注册任何插件都需要检查该插件是否受支持。)
In case of the cordova, the method isSupported checks for the following:(如果是cordova，则isSupported方法检查以下内容：)
if (s._capabilities != null || !(window.cordova || window.PhoneGap || window.phonegap) || !window.Media) { return;}
This means when the app is compiled, there is no global variable called window.cordova or phonegap and no global variable called window.media (I think this is the media plugin that needs to be installed to get soundjs to work, and I have added it to the config.xml that I'm using for phonegap build.
(这意味着在编译应用程序时，没有名为window.cordova或phonegap的全局变量，也没有名为window.media的全局变量（我认为这是需要安装的媒体插件才能使soundjs正常工作，我已经添加了它到我用于phonegap构建的config.xml中。)
So the question is, how to investigate what is wrong, how to know if for example the media plugin is not installed properly (all from the javascript variables that we can use, as I am not able to use any other debugging), or is it the case that when I compile using phonegap build there is no variables for cordova or phonegap.. can we list all global variables to see which ones are used?
(所以问题是，如何调查出了什么问题，如何知道例如媒体插件安装不正确（全部来自我们可以使用的javascript变量，因为我无法使用任何其他调试功能），或者当我使用phonegap构建进行编译的情况下，cordova或phonegap没有变量..我们能否列出所有全局变量以查看使用了哪些全局变量？)
Edit Thanks Jesse for drawing my attention to these points about phonegap, so I built a small app just to test the deviceready event, but for some reason it still doesn't work when compiled by phonegap build:
(编辑感谢Jesse提请我注意关于phonegap的这些要点，因此我构建了一个小应用程序只是为了测试deviceready事件，但是由于某些原因，当通过phonegap构建进行编译时，它仍然不起作用：)

Can you please help me locate where can the problem be?
(您能帮我找出问题所在吗？)
EDIT2 I figured out that the deviceready was not working because I didn't add cordova:
(EDIT2我发现该设备无法使用，因为我没有添加cordova：)
<script type="text/javascript" src="cordova.js"></script>
So, when I did, I was able to initialize the cordova audio plugin.
(这样，当我这样做时，便能够初始化cordova音频插件。)
However, I am still unable to play sound, despite using mobile safe approach:(但是，尽管使用了移动安全方式，我仍然无法播放声音：)
