Is there a way for a browser to take a global screenshot ? I mean, the entire screen, including what is not in the browser.
浏览器有没有办法截取全局截图？我的意思是，整个屏幕，包括浏览器中没有的内容。
I kown that I may sound a little bit silly by asking this.
我知道问这个可能听起来有点傻。

There is experimental support for full-screen capturein Chrome's getUserMediaWebRTC function, using a {chromeMediaSource: 'screen'}parameter. The functionality currently requires explicit activation by an option in chrome://flags, and (like all WebRTC capture mechanisms) requires explicit consent from the user when the function is called.
Chrome 的WebRTC 功能中有对全屏捕获的实验性支持getUserMedia，使用{chromeMediaSource: 'screen'}参数。该功能目前需要通过 中的选项显式激活chrome://flags，并且（与所有 WebRTC 捕获机制一样）在调用该功能时需要用户的明确同意。
Other than that experimental option in Chrome, is not possible using pure JavaScript, but you could probably do it using a plugin like Flash, or an ActiveX control.
除了 Chrome 中的实验性选项之外，使用纯 JavaScript 是不可能的，但您可以使用 Flash 或 ActiveX 控件等插件来实现。
If you only want to capture a web page (rather than the whole screen), see Using HTML5/Canvas/JavaScript to take screenshots.
如果您只想截取网页（而不是整个屏幕），请参阅使用 HTML5/Canvas/JavaScript 截取屏幕截图。
