Question

我收到此错误。

未捕获的TypeError：对象＃在文件中没有方法'exec'：///android_asset/www/JS/pg-plugin-screen-orientation.js：4

var screenOrientation = function() {}

screenOrientation.prototype.set  = function(str, success, fail) {

 PhoneGap.exec(success, fail, "ScreenOrientation", "set", [str]); // GETTING ERROR IN THIS LINE

};

navigator.screenOrientation = new screenOrientation();

我已按照本文档中给出的步骤操作。 https://github.com/champierre/pg-plugin-screen-orientation

现在工作正常。但是当这一行被执行时，应用程序崩溃了

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Answer 1

您使用的是哪个版本的PhoneGap / Cordova？在最近的版本中，PhoneGap对象已重命名为cordova。因此，您可能需要更新JS文件以调用cordova.exec而不是PhoneGap.exec。

Answer 2

我在调用exec时遇到此错误。在
