JS to determine browser type and language

1, check whether it is mobile, ipad, iphone, QQ, etc.

<script type= "Text/javascript" >//Judging the access terminal        varBrowser={versions:function(){            varU =navigator.useragentreturn{trident:u.indexof (' Trident ') >-1,//IE kernelPresto:u.indexof (' presto ') >-1,//Opera KernelWebkit:u.indexof (' AppleWebKit ') >-1,//Apple, Google kernelGecko:u.indexof (' Gecko ') >-1 && u.indexof (' khtml ') = =-1,//Firefox kernelMobile:!! U.match (/applewebkit.*mobile.*/),//whether it is a mobile terminalIos:!! U.match (/\ (i[^;] +;( U;)? Cpu.+mac OS x/),//iOS terminalAndroid:u.indexof (' Android ') >-1 | | U.indexof (' Adr ') >-1,//Android TerminalIphone:u.indexof (' IPhone ') >-1,//whether it's an iphone or Qqhd browserIpad:u.indexof (' IPad ') >-1,//whether ipadWebapp:u.indexof (' Safari ') = =-1,//whether the web should program, no head with the bottomWeixin:u.indexof (' Micromessenger ') >-1,//isQq:u.match (/\sqq/i) = = "QQ"//whether QQ                }; }(),          //languageLanguage: (Navigator.browserlanguage | |navigator.language). toLowerCase ();</script>

How to use:

//determine if IE kernel        if(browser.versions.trident) {alert ("is IE browser"); }         //determine if the kernel is WebKit        if(Browser.versions.webKit) {Alert ("is WebKit kernel browser"); }         //determine if the mobile side        if(browser.versions.mobile| | browser.versions.android| | Browser.versions.ios) {alert ("mobile"); }        //determine if a browser is built in        if(browser.versions.weixin) {alert ("Built-in browser")}        //determine if QQ built-in browser        if(BROWSER.VERSIONS.QQ) {alert ("QQ built-in browser")}        //Judgment Language        if(Browser.language.indexOf (' zh ') >-1) {alert (Chinese); }Else if(Browser.language.indexOf (' en ') >-1) {alert (English)        }Else{alert (' Other languages ')        }

2, only judge, can be abbreviated like this

    if (Navigator.userAgent.indexOf (' Micromessenger ') >-1) {               alert (' inside ');        } Else {            alert (' outside ')        }    

3. Only the browser language is judged

var language = (Navigator.browserlanguage | | navigator.language). toLowerCase (); if (Language.indexof (' zh ') >-1) {    alert (' Chinese ');} Else if (Language.indexof (' en ') >-1) {    alert (' English ')}else{    alert (' Other languages ')}

4, Judge iphone|ipad|ipod|ios| Android Client | PC-side, jump to different pages separately

if // Judging Iphone|ipad|ipod|ios  Window.location.href = "iphone.html";} Else if (/(Android)/i.test (navigator.useragent)) {  // judging Android  window.location.href = "android.html";} Else // pc  Window.location.href = "pc.html";};

5. Determine if it is iOS or Android client

if (Navigator.userAgent.match (/\ (i[^;] +;( U;)? Cpu.+mac OS x/){    alert ("IOS");} Else if (Navigator.userAgent.indexOf (' Android ') >-1 | | navigator.userAgent.indexOf (' ADR ') >-1) {    alert (" Android ")}

6, judge the PC or mobile end

functionIsPC () {varUseragentinfo =navigator.userAgent.toLowerCase (); varAgents = ["Android", "iphone", "SymbianOS", "Windows Phone", "ipad", "ipod"];  for(varv = 0; v < agents.length; v++) {        if(Useragentinfo.indexof (agents[v]) >= 0) {alert ("Mobile Side"); return false; }    }    return true;} 

7. Determine the version of IE browser

functionieversion () {varuseragent = navigator.useragent;//get the useragent string for the browser    varIsie = Useragent.indexof ("compatible") >-1 && useragent.indexof ("MSIE") >-1;//determine if the browser is ie<11    varIsedge = Useragent.indexof ("Edge") >-1 &&!isie;//determine if IE's Edge browser    varisIE11 = Useragent.indexof (' Trident ') >-1 && useragent.indexof ("rv:11.0") > 1; if(Isie) {varReie =NewRegExp ("MSIE (\\d+\\.\\d+);");        Reie.test (useragent); varFieversion = parsefloat (regexp["$"]); if(Fieversion = = 7) {            return7; } Else if(Fieversion = = 8) {            return8; } Else if(Fieversion = = 9) {            return9; } Else if(Fieversion = = 10) {            return10; } Else {            return6;//IE version <=6        }       } Else if(Isedge) {return' Edge ';//Edge}Else if(isIE11) {return11;//IE11}Else{        return-1;//Not IE browser    }}
