JS to determine whether the Apple system (ios) and Android system (Android) client

<!--By determining the browser's userAgent, use a regular to determine if it is an ios and Android client. The code is as below -->
 
<script type="text/javascript">
    var u = navigator.userAgent;
    var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android终端
    var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/); //ios终端
    alert('Is it Android：'+isAndroid);
    alert('Is it IOS：'+isiOS);
    
    //Or just use the regular, i is case-ignoring
    checkPlatform(){
	if(/android/i.test(navigator.userAgent)){
		console.log("Android");//Android
	}
	if(/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)){
		console.log("iOS");//iOS
	}
}

</script>

Js determine whether the client is PC or mobile access

//Method 1
function IsPC(){  
     var userAgentInfo = navigator.userAgent;
     var Agents = new Array("Android", "iPhone", "SymbianOS", "Windows Phone", "iPad", "iPod");  
     var flag = true;  
     for (var v = 0; v < Agents.length; v++) {  
         if (userAgentInfo.indexOf(Agents[v]) > 0) { flag = false; break; }  
     }  
     return flag;  
  }


//Method 2
if (/(iPhone|iPad|iPod|iOS)/i.test(navigator.userAgent)) {
    //alert(navigator.userAgent);  
    window.location.href ="iPhone.html";
} else if (/(Android)/i.test(navigator.userAgent)) {
    //alert(navigator.userAgent); 
    window.location.href ="Android.html";
} else {
    window.location.href ="pc.html";
};

Js determine what browser to run with

  var browser={
    versions:function(){ 
           var u = navigator.userAgent, app = navigator.appVersion; 
           return {//Mobile Browser Version Information 
                trident: u.indexOf('Trident') > -1, //IE
                presto: u.indexOf('Presto') > -1, //opera
                webKit: u.indexOf('AppleWebKit') > -1, //Apple, Google Kernel
                gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //Firefox kernel
                mobile: !!u.match(/AppleWebKit.*Mobile.*/), //Whether it is a mobile terminal
                ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios
                android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android terminal or uc browser
                iPhone: u.indexOf('iPhone') > -1 , //Whether for iPhone or QQHD browser
                iPad: u.indexOf('iPad') > -1, //iPad
                iEdg: u.indexOf('Edg') > -1, // Microsoft edge
               webApp: u.indexOf('Safari') == -1, //Whether the web should be programmed with no header & footer
                weixin: u.indexOf('MicroMessenger') > -1, //Wechat
                qq: u.match(/\sQQ/i) == " qq" //QQ
            };
         }(),
         language:(navigator.browserLanguage || navigator.language).toLowerCase()
} 
 
  if(browser.versions.mobile || browser.versions.ios || browser.versions.android || 
  	browser.versions.iPhone || browser.versions.iPad){  	
   		window.location = "http://m.lllomh.com";	
  }
