js to achieve browser full screen
When the page automatically triggers full screen, an error will be reported, and the browser will give a warning as follows, which means that the browser full screen API can only be triggered by user gestures . Tried window.onload, timer, mouse movement event can not achieve full screen, click event can. 
Full screen api document address: https://developer.mozilla.org/zh-CN/docs/Web/API/Fullscreen_API
Simple implementation of click full screen code:
<body>
<button onclick="fullScreen()">浏览器全屏</button>
</body>
<script type="text/javascript">
//实现全屏
function fullScreen() {
// documentElement 属性以一个元素对象返回一个文档的文档元素
var el = document.documentElement;
el.requestFullscreen||el.mozRequestFullScreen||el.webkitRequestFullscreen||el.msRequestFullScreen?
el.requestFullscreen()||el.mozRequestFullScreen()|| el.webkitRequestFullscreen()||el.msRequestFullscreen():null;
}
</script>
Google, Firefox, Edg, 360 speed mode can all achieve full screen, 360 compatibility mode does not take effect
