JS to determine if the client is iOS or Android

* * First: By judging the browser's useragent, use the regular to determine whether it is an iOS and android client. The code is as follows: *

<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(‘是否是Android：‘+isAndroid);
    alert(‘是否是iOS：‘+isiOS);
</script>

* * The second type: check whether the mobile side (Mobile), ipad, iphone, QQ, etc. **

<script type= "Text/javascript" >
Judging the access terminal
var browser={
Versions:function () {
var u = navigator.useragent,
App = Navigator.appversion;
return {
Trident:u.indexof (' Trident ') >-1,//ie core
Presto:u.indexof (' presto ') >-1,//opera core
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 terminal
Android:u.indexof (' Android ') >-1 | | U.indexof (' Adr ') >-1,//android terminal
Iphone:u.indexof (' iphone ') >-1,//whether for iphone or Qqhd browser
Ipad:u.indexof (' ipad ') >-1,//whether ipad
Webapp:u.indexof (' Safari ') = =-1,//whether the Web should be program, no head with bottom
Weixin:u.indexof (' Micromessenger ') >-1,//whether (added 2015-01-22)
Qq:u.match (/\sqq/i) = = "QQ"//whether QQ
};
}(),
Language: (Navigator.browserlanguage | | navigator.language). toLowerCase ()
}
</script>


How to use:

Determine if IE kernel
if (browser.versions.trident) {alert ("is IE");}
Determine if the kernel is WebKit
if (browser.versions.webKit) {alert ("is WebKit");}
Determine if the mobile side
if (browser.versions.mobile| | browser.versions.android| | Browser.versions.ios) {alert ("mobile Side");}

Detecting Browser language

Currentlang = Navigator.language; Determine the language used by other browsers except IE
if (!currentlang) {//To determine the language used by IE browser
Currentlang = Navigator.browserlanguage;
}
alert (Currentlang);

* * The third type: judging iphone|ipad|ipod|ios| Android client, from http://www.fufuok.com/js-iphone-android.html**

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

* * Fourth: Judging the PC or the mobile side * *

                  "SymbianOS", "Windows Phone", 
                  "ipad", "ipod"); 
     var ly=document.referrer; //Returns the URL of the page that contains the hyperlink that navigates to the current page 
 
     for (var v = 0; v < agents.length; v++) {
         if (Useragentinfo.indexof (Agents[v]) >= 0&& (ly== "" | | Ly==null) {
             this.location.href= ' http://m.***.com ';  //wap End Address 
        } 
     } 
 </script>
