问题描述
我正在使用 JavaScript、node.js 和 Electron 构建一个应用程序.
I am building an application using JavaScript, node.js, and Electron.
此应用程序的一部分旨在锁定计算机，直到用户进行身份验证.
Part of this application is designed to lock the computer until the user authenticates themselves.
这可行，但是我需要让我的应用程序禁用 alt + tab 键盘快捷键，因为目前用户可以使用它来跳过我的锁定页面(并且从而能够在没有经过身份验证的情况下使用计算机).
This works, however I need to make my application disable the alt + tab keyboard shortcut, as currently the user can use this to skip over my lock page (and thus be able to use the computer without having been authenticated).
任何建议将不胜感激.
推荐答案
您可以为窗口打开信息亭模式，使其全屏并始终在顶部，这样您就无法转到其他应用程序.
You could turn on kiosk mode for the window which makes it full screen and always on top so you can't go to another application.
您还可以使窗口透明并将登录信息放置在屏幕中间，这样看起来就好像屏幕中间有一个窗口，但您不能点击屏幕的其他区域.
You could also make the window transparent and position the login in the middle of the screen so it appears as if there is one window in the middle of the screen but you can't click on other areas of the screen.
要处理 Alt+F4 可以使用 window.onbeforeunload 事件或调用 event.preventDefault()close 事件中的 code>.
To handle for Alt+F4 you can use the window.onbeforeunload event or call event.preventDefault() in the close event.
