js 实现 F11 全屏成果

提醒

该事件只能从用户操作的事件触发，因为全屏后看不到地址栏，很容易做成坑骗性质的钓鱼网站

1. 关上全屏：

       const docElm = document.documentElement;
       if (docElm.requestFullscreen) {docElm.requestFullscreen();  
       }  
       else if (docElm.mozRequestFullScreen) {docElm.mozRequestFullScreen();  
       }  
       else if (docElm.webkitRequestFullScreen) {docElm.webkitRequestFullScreen();  
       }  
       else if (elem.msRequestFullscreen) {elem.msRequestFullscreen();  
       } 

2. 退出全屏：

       if (document.exitFullscreen) {document.exitFullscreen();  
       }  
       else if (document.mozCancelFullScreen) {document.mozCancelFullScreen();  
       }  
       else if (document.webkitCancelFullScreen) {document.webkitCancelFullScreen();  
       }  
       else if (document.msExitFullscreen) {document.msExitFullscreen();  
       }
