I saw on Facebook and other apps that Don't allow users to taking screenshots.我在 Facebook 和其他不允许用户截屏的应用程序上看到。 When we swipe down 3 fingers, or click power button and volume Down btn together, it says "Taking Screenshots is not allowed by the app or your organisation".当我们向下滑动 3 个手指，或同时单击电源按钮和降低音量按钮时，它会显示“应用程序或您的组织不允许截屏”。 How do they do it.他们是怎么做到的呢。

It is not possible to block taking screenshot on websites through JavaScript. The only way you might be able to do it is only if you are displaying the website in your own app on Android, it is possible to set FLAG_SECURE in your code.无法通过 JavaScript 阻止在网站上截取屏幕截图。只有当您在 Android 上在自己的应用程序中显示该网站时，您才能做到这一点，可以在您的代码中设置FLAG_SECURE 。 You can read more about it here .您可以在此处阅读更多相关信息。 Just mind the fact that any rooted device would be able to go around it anyway.请记住一个事实，即任何有根设备无论如何都可以 go 绕过它。
