如何让 ExtJS 使用外部变量构建

如何解决如何让 ExtJS 使用外部变量构建

我正在尝试做一个

sencha 应用构建

在我的项目中 - 但它使用“broadcastChannel”并且我收到构建错误：

== Unhandled Error ==
ReferenceError: Can'''t find variable: broadcastChannel

  file:[.Stuff.]/PopupWindowWithComms.js:11 in global code

（如果我进行 sencha 应用程序构建开发 - 很好..）

有什么办法让它接受那只是一个可用的全局变量吗？

我试过了

/*全局变量广播频道 */

只是偶然，但这似乎没有帮助
