javascript - 用于更改屏幕方向的 phonegap 插件出错

Question

我遇到了这个错误。

Uncaught TypeError: Object # has no method 'exec' at file:///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进行操作。 https://github.com/champierre/pg-plugin-screen-orientation

现在它工作正常。但是当这条线被执行时应用程序崩溃了

activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Answer 1

您使用的是什么版本的 PhoneGap/Cordova？ PhoneGap 对象在最新版本中已重命名为 cordova。因此，您可能需要更新 JS 文件以调用 cordova.exec 而不是 PhoneGap.exec。
