解决监听全屏状态下esc退出全屏

//判断是否全屏
const checkFull=()=> {
    var isFull =
        document.fullscreenElement ||
        document.mozFullScreenElement ||
        document.webkitFullscreenElement;//兼容不同浏览器
    //to fix : false || undefined == undefined
    if (isFull === undefined) isFull = false;
    return isFull;
}
//监听窗口退出全屏解决无法监听Esc按键
window.onresize = function () {
    if (!checkFull()) {
        //要执行的动作
        isFull.value = false;//样式改变
       console.log("退出全屏")
    }
}
