推荐答案

这是不可能的。

我跑了我的浏览器控制台中的以下代码段：

I ran the following snippet in my browser console:

var e = document.getElementById('answers');
(e.webkitRequestFullScreen || e.mozRequestFullScreen).apply(e);

Chrome告诉我：

Chrome told me:

无法在'Element'上执行'requestFullScreen'：API只能通过用户手势发起。

Failed to execute 'requestFullScreen' on 'Element': API can only be initiated by a user gesture.

Firefox告诉我：

Firefox told me:

全屏的请求被拒绝，因为没有从短暂运行的用户生成的事件中调用Element.mozRequestFullScreen（）处理程序。

Request for full-screen was denied because Element.mozRequestFullScreen() was not called from inside a short running user-generated event handler.

这是一个防止滥用的限制，类似于 window.open （请参阅此或这个问题，例如）。

That is a restriction put in place to prevent abuse, similar to that on window.open (see this or this question for example).
