推荐答案

有一个实验性的全屏API，但它在浏览器之间并不一致：

http://caniuse.com/#feat=fullscreen [ ^ ]



GitHub上有一个项目尝试将这些更改隐藏在一致的API背后：

https://github.com/sindresorhus/screenfull。 js / [ ^ ]



然而，此API将 NOT 允许您在没有用户交互的情况下进入全屏模式，它将 NOT 阻止用户退出全屏模式。这是好的事情。如果随机网站能够接管整个屏幕，并阻止您访问计算机上的任何其他内容，那将是一个主要的安全问题。

There is an experimental full-screen API, but it's not consistent between browsers:
http://caniuse.com/#feat=fullscreen[^]

There's a project on GitHub which attempts to hide these changes behind a consistent API:
https://github.com/sindresorhus/screenfull.js/[^]

However, this API will NOT allow you to enter full-screen mode without user interaction, and it will NOT prevent the user from exiting full-screen mode. And that's a good thing. If a random website was able to take over your entire screen, and prevent you from accessing anything else on your computer, that would be a major security problem.
