【问题描述】：

我必须使用这个插件在 cordova 中制作一个 android 应用程序：https://github.com/sezerkorkmaz/cordova-plugin-sip 但是当我尝试使用一些插件功能时，我收到了这个错误消息：

index.js:23 Uncaught TypeError: Cannot read property 'sip' of undefinedat Object.register (index.js:23) at HTMLButtonElement。 (index.js:74)注册@index.js:23 (匿名)@index.js:74

这是我的代码，我只想做一些基础知识，如何为别人使用连接函数和调用函数，我对编程很陌生

将此行添加到您的 js 文件并检查：

声明 const cordova: any;
