html5 to determine what equipment

We will use html5 to determine what device is currently moving. The following code of the look around pc can be judged

<script type="text/javascript">
		 $(function(){
    
    

		    var system = {
    
    
		        win: false,
		        mac: false,
		        xll: false,
		        ipad:false
		    };

		    //检测平台
		    var p = navigator.platform;

		    system.win = p.indexOf("Win") == 0;
		    system.mac = p.indexOf("Mac") == 0;
		    system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
		    system.ipad = (navigator.userAgent.match(/iPad/i) != null)?true:false;

		    if (system.win || system.mac || system.xll ||system.ipad) {
    
    
		      	
		    } else {
    
    

		       some code;
		    }

		})
		$(function(){
    
    
		 if (!navigator.userAgent.match(/mobile/i)) {
    
    
		//PC端
				console.log("PC端");
		        }else{
    
    console.log("移动端");
		//移动端
		}
		})
	</script>
