当我的Web应用程序正在使用时，我想阻止使用任何计算机应用程序

Question

I am developing an on-line examination portal. I want to block accessing/using of all other application, when the candidates attending exams. I know, we ca not control a computer only with browser's client side scripting. Is any other option for achieving my requirement [Any applications that can be called with JavaScript or anything like that].

Answer 1

就像马克·贝克和哈里·约翰斯顿（Baker And Harry Johnston）所说的那样，不可能在浏览器中执行此操作。您无法使用浏览器控制其他应用程序。也许您可以通过代码而非其他任何应用程序来控制网站甚至浏览器。
