为了客户需要,我需要使用Sencha Touch和Cordova构建原生应用程序。
为了提高性能,我使用SDK工具中的“sencha app build package”命令来压缩JavaScript源代码。
如果我在开发中使用Sencha并且使用Corova进行Webview,则没有问题。但是,我需要使用Cordova函数(如FileSystem等),这是我无法在Sencha中完成的。
问题在于当我使用“sencha app build package”时,会出现错误,例如“[ERROR] ReferenceError:Can't find variable: fileSystem”。
我阅读了许多关于Sencha + Cordova的文章,但其中没有一篇涉及使用Cordova + Sencha构建/压缩源码。
是否有人遇到过这个问题,以及您是如何解决的?

我为每个需要访问cordova变量的方法使用一个名为CordovaFunctions.js的文件,并且我的app.js和其他View / Controller调用CordovaFunctions.js中的方法...
