FullScreen works onclick but not onload
提问by ispiro
I'm trying the code from hereto start fullscreen mode. It works if executed onclick, but not onload. (I've also discovered that setting an alertbefore it will disable it unless the alertis clicked immediately.) So perhaps the problem is that sometimes the browser isn't 'ready' for fullscreen.
我正在尝试使用此处的代码来启动全屏模式。如果执行onclick，它会起作用，但不会onload。（我还发现alert在它之前设置一个会禁用它，除非alert立即点击它。）所以也许问题是有时浏览器没有“准备好”全屏。
So what is the last event fired when a page is completely ready? Or is the solution different?
那么当页面完全准备好时，最后触发的事件是什么？还是解决方法不一样？

Fullscreen requires user interaction to initiate. It's a security feature.
全屏需要用户交互才能启动。这是一个安全功能。
Imagine if some pop-up could force you into fullscreen mode, lock your mouse pointer, and start playing an advertisement without your permission.
想象一下，如果某个弹出窗口可以强制您进入全屏模式，锁定鼠标指针，并在未经您许可的情况下开始播放广告。
Having a 'enable full screen' link or button who's visibility is toggled in the document 'fullscreenchange' event handler seems like a practical approach.
在文档“fullscreenchange”事件处理程序中切换可见性的“启用全屏”链接或按钮似乎是一种实用的方法。

Was trying to do this myself then I came to this site Fullscreen API Phishing Attacks
试图自己做这件事然后我来到了这个网站Fullscreen API Phishing Attacks
Basically, if fullscreen mode was allowed onload, we don't know if site is actual website...fake site can have the lock logo saying it's safe, etc.
基本上，如果允许全屏模式加载，我们不知道网站是否是实际网站……假网站可以有锁标志，表示它是安全的，等等。
