Question

对于客户端，我需要使用Sencha Touch和Cordova构建本机应用程序。

为了提高性能，我使用SDK Tools中的命令“sencha app build package”来缩小javascript源代码。

如果我使用Sencha进行开发，使用Corova进行webview，则没有问题。但是我需要使用Cordova函数（比如FileSystem，...），这是Sencha无法做到的。

问题在于，当我使用“sencha app build package”时，我遇到了[ERROR] ReferenceError: Can't find variable: fileSystem等错误。

我阅读了许多关于Sencha + Cordova的帖子，但没有人谈论Cordova + Sencha的构建/缩小源代码。

有没有人遇到过这个问题，你是怎么解决的？

祝你好运

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，我的app.js和其他View / Controller调用CordovaFunctions.js中的方法......

这是我的app.json：

{
/**
 * The application's namespace, used by Sencha Command to generate classes
 */
"name": "ImageDownloader",

/**
 * The file path to this application's front HTML document, relative to this app.json file
 */

/**
 * The absolute URL to this application in development environment, i.e: the URL to run this application
 * on your web browser during development, e.g: "http://localhost/myapp/index.html".
 *
 * This value is needed when build to resolve your application's dependencies if it requires server-side resources
 * that are not accessible via file system protocol.
 */

在app.json配置文件中，您需要告诉Sencha构建命令您的应用程序需要phoneGap库。将其添加到js节点：

/**
 * List of all JavaScript assets in the right execution order.
 * Each item is an object with the following format:
 *      {
 *          "path": "path/to/script.js" // Relative path to this app.json file
 *          "update": "delta"           // (Optional)
 *                                      //  - If not specified, this file will only be loaded once, and
 *                                      //    cached inside localStorage until this value is changed.
 *                                      //  - "delta" to enable over-the-air delta update for this file
 *                                      //  - "full" means full update will be made when this file changes
 *
 *      }
 */
"js": [
    {
        "path": "sdk/sencha-touch.js"
    },
    {
        "path": "cordova-1.5.0.js"
    },
    {
        "path": "app.js",
        "bundle": true,  /* Indicates that all class dependencies are concatenated into this file when build */
        "update": "delta"
