Weird question !

I was wondering if there was any action a website could do to make the user's screensaver disappear.

I wanted to create kind of an alarm-clock website, but with nice visual effects, and I wished I could make the user leave their screensaver.

Is there any action that wakes up the computer ? Like, I don't know, making the website fullscreen, moving the window around.. Or is the screensaver only and exclusively left through keyboard/mouse events ?

I've read that you can't interact with the screensaver with JS : javascript code to prevent screensaver from starting

But I was hoping something like putting the website fullscreen would wake the computer up.

没有。

出于安全原因，浏览器内运行的任何内容都无法访问此类操作系统级别的命令。

仅仅弹出一个警告框是不行的。全屏也不行，无论如何，你不能在计时器上全屏。我刚刚尝试过，显然有浏览器保护措施。如果您请求全屏作为用户交互的直接结果，例如单击，则全屏没问题。但是，将完全相同的代码放入 setTimeout() 函数中，它就无法运行。

对于警报类型应用程序，您有两个选项：

1) 用声音来做。设置<audio>标签并将其设置为在 setTimeout 上播放。

2) Chrome 应用程序提供对不同事物的更多访问，这些事物比典型网页需要更高的安全性。我不知道他们是否允许足够的访问权限来做你想做的事，但你可以在这里阅读：http: //developer.chrome.com/apps/first_app.html

希望有帮助。
