浏览器可能是处于安全的考虑，无法实现进入页面自动全屏，只能通过用户操作的形式触发全屏！！！
ps：可以通过登录按钮触发登录成功自动全屏
实测vue中可通过登录点击事件加载组件自动全屏
import { useFullscreen } from '@vueuse/core'const { isFullscreen, enter, exit, toggle } = useFullscreen();toggle();同理这个应该也可以实现（没有测试）
import screenfull from 'screenfull'
// 切换全屏
screenfull.toggle()
第一种形式：点击按钮实现全屏和退出全屏
<!DOCTYPE html>
<html><head><script>window.onload = openfullscreen();function launchIntoFullscreen(element) {if (element.requestFullscreen) {element.requestFullscreen();} else if (element.mozRequestFullScreen) {element.mozRequestFullScreen();} else if (element.webkitRequestFullscreen) {element.webkitRequestFullscreen();} else if (element.msRequestFullscreen) {element.msRequestFullscreen();}}function openfullscreen() {launchIntoFullscreen(document.documentElement);}function exitFullscreen() {if (document.exitFullscreen) {document.exitFullscreen();} else if (document.mozCancelFullScreen) {document.mozCancelFullScreen();} else if (document.webkitExitFullscreen) {document.webkitExitFullscreen();}window.close();}function fix() {var screenwidth = screen.width;var screenhei = screen.height;document.getElementById("ifam").width = screenwidth;document.getElementById("ifam").height = screenhei;}</script><style>#ifam {position: fixed;left: 0%;top: 0%;z-index: -1;}#fullscreen {position: fixed;left: 0%;top: 0%;z-index: 1;}</style></head><body onload="fix()"><div id="fullscreen"><button onclick="openfullscreen()">Open</button><button onclick="exitFullscreen()">Exit</button></div><iframe id="ifam" src="https://docs.python.org"></iframe></body>
</html>
第二种形式：点击页面任何位置实现全屏
<html><head><script language="jscript">function goFullscreen() {// Must be called as a result of user interaction to workmf = document.getElementById("main_frame");mf.webkitRequestFullscreen();mf.style.display = "";}function fullscreenChanged() {if (document.webkitFullscreenElement == null) {mf = document.getElementById("main_frame");mf.style.display = "none";}}document.onwebkitfullscreenchange = fullscreenChanged;document.documentElement.onclick = goFullscreen;document.onkeydown = goFullscreen;</script></head><body style="margin: 0"><h1>Click anywhere or press any key to browse <u>Python documentation</u> infullscreen.</h1><iframeid="main_frame"src="https://docs.python.org"style="width: 100%; height: 100%; border: none; display: none"></iframe></body>
