The API only works during user interaction, so it cannot be used maliciously. Try the following code:
该 API 仅在用户交互期间起作用，因此不能被恶意使用。试试下面的代码：
addEventListener("click", function() {
var el = document.documentElement,
rfs = el.requestFullscreen
|| el.webkitRequestFullScreen
|| el.mozRequestFullScreen
|| el.msRequestFullscreen
;
rfs.call(el);
});

I made a simple wrapper for the Fullscreen API, called screenfull.js, to smooth out the prefix mess and fix some inconsistencies in the different implementations. Check out the demoto see how the Fullscreen API works.
我为 Fullscreen API 制作了一个简单的包装器，称为screenfull.js，以消除前缀混乱并修复不同实现中的一些不一致。查看演示以了解 Fullscreen API 的工作原理。

Here are some functions I created for working with fullscreen in the browser.
以下是我为在浏览器中使用全屏而创建的一些函数。
They provide both enter/exit fullscreen across most major browsers.
它们在大多数主要浏览器中都提供进入/退出全屏显示。
function isFullScreen()
{
return (document.fullScreenElement && document.fullScreenElement !== null)
|| document.mozFullScreen
|| document.webkitIsFullScreen;
}
function requestFullScreen(element)
{
if (element.requestFullscreen)
element.requestFullscreen();
else if (element.msRequestFullscreen)
element.msRequestFullscreen();
else if (element.mozRequestFullScreen)
element.mozRequestFullScreen();
else if (element.webkitRequestFullscreen)
element.webkitRequestFullscreen();
}
function exitFullScreen()
{
if (document.exitFullscreen)
document.exitFullscreen();
else if (document.msExitFullscreen)
document.msExitFullscreen();
else if (document.mozCancelFullScreen)
document.mozCancelFullScreen();
else if (document.webkitExitFullscreen)
document.webkitExitFullscreen();
}
function toggleFullScreen(element)
{
if (isFullScreen())
exitFullScreen();
else
requestFullScreen(element || document.documentElement);
}
