Question

我刚刚安装了cordova并且我正在编写我的第一个应用程序，并在我第一次测试时安装了这个插件“cordova-plugin-facebook4”，当我把插件登录代码放在后面时：onDeviceReady它显示了facebook登录一旦我运行命令“cordova run android”，但是我创建了一个events.js文件并且我正在进行测试以点击事件上的facebook登录而没有运气，当我点击时我得到以下错误 - ＆gt;

events.js:10 Uncaught ReferenceError: facebookConnectPlugin is not defined
at HTMLButtonElement.<anonymous> (events.js:10)
at HTMLButtonElement.dispatch (jquery-2.2.4.js:4737)
at HTMLButtonElement.elemData.handle (jquery-2.2.4.js:4549)

这里我附上我的代码
