JS to determine the mobile side or PC side

JS to determine whether the client is a PC or handheld mobile device
Method One

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;
}

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";
};
Method Two

var browser={
Versions:function () {
var u = navigator.useragent, app = Navigator.appversion;
return {//Mobile terminal browser version information
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 (' Linux ') >-1,//android terminal or UC Browser
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
Qq:u.match (/\sqq/i) = = "QQ"//whether 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.zhaizhainv.com";
}

Method Three: excerpted from IM-QQ

var os = function () {
var ua = navigator.useragent,
Iswindowsphone =/(?: Windows Phone)/.test (UA),
Issymbian =/(?: SymbianOS)/.test (UA) | | Iswindowsphone,
Isandroid =/(?: Android)/.test (UA),
Isfirefox =/(?: Firefox)/.test (UA),
Ischrome =/(?: chrome| Crios)/.test (UA),
Istablet =/(?: ipad| PlayBook)/.test (UA) | | (Isandroid &&!/(?: Mobile)/.test (UA)) | | (Isfirefox &&/(?: Tablet)/.test (UA)),
Isphone =/(?: IPhone)/.test (UA) &&!istablet,
IsPc =!isphone &&!isandroid &&!issymbian;
return {
Istablet:istablet,
Isphone:isphone,
Isandroid:isandroid,
Ispc:ispc
};
}();
How to use
if (os.isandroid | | os.isphone) {

Alert ("-----");

}

Method Four:

if (/applewebkit.*mobile/i.test (navigator.useragent) | | (/midp| symbianos| nokia| Samsung| Lg| nec| tcl| alcatel| bird| dbtel| dopod| philips| haier| lenovo| mot-| nokia| sonyericsson| sie-| amoi| Zte/.test (navigator.useragent))) {
if (Window.location.href.indexOf ("mobile") <0) {
try{
if (/android|webos|iphone|ipod| Blackberry/i.test (navigator.useragent)) {
window.location.href= "Mobile page";
}else if (/ipad/i.test (navigator.useragent)) {
window.location.href= "Flat page";
}else{
Window.location.href= "Other mobile pages"
}
}catch (e) {}
}
}
Method Five
<script language= "JavaScript" >
platforms, devices, and operating systems
var system ={
Win:false,
Mac:false,
Xll:false
};
Testing platform
var p = navigator.platform;
System.win = P.indexof ("win") = = 0;
System.mac = P.indexof ("mac") = = 0;
system.x11 = (P = = "X11") | | (P.indexof ("Linux") = = 0);
Jump statement, if it is mobile Access will automatically jump to the caibaojian.com page
if (system.win| | system.mac| | SYSTEM.XLL) {
}else{
Window.location.href= "http://caibaojian.com";
}
</script>
Method Six
<script language= "JavaScript" >
function Is_mobile () {
var regex_match =/(nokia|iphone|android|motorola|^mot-|softbank|foma|docomo|kddi|up.browser|up.link|htc|dopod| blazer|netfront|helio|hosin|huawei|novarra| coolpad|webos|techfaith|palmsource|blackberry|alcatel|amoi|ktouch|nexian|samsung|^sam-|s[cg]h|^lge|ericsson| Philips|sagem|wellcom|bunjalloo|maui|symbian|smartphone|midp|wap|phone|windows ce|iemobile|^spice|^bird|^zte-| Longcos|pantech|gionee|^sie-|portalmmm|jigs browser|hiptop|^benq|haier|^lct|operas*mobi|opera*mini|320x320| 240x320|176x220)/I;
var u = navigator.useragent;
if (null = = u) {
return true;
}
var result = regex_match.exec (u);

if (null = = result) {
return False
} else {
return True
}
}
if (Is_mobile ()) {
document.location.href= ' http://caibaojian.com '; Modify http://caibaojian.com to the destination page address you want to jump to
}

<script language= "JavaScript" >
(function () {
var res = getrequest ();

if (par!= ' Gfan ') {
var ua=navigator.useragent.tolowercase ();

Change the following http://caibaojian.com to your WAP mobile page address like my http://caibaojian.com
var tomobilevertion = function () {

}

If (Contains (UA, "ipad") | | (Contains (UA, "rv:1.2.3.4")) | | (Contains (UA, "0.0.0.0")) | | (Contains (UA, "8.0.552.237"))) {return False}

|| Contains (UA, "Ucweb7") | | Contains (UA, "iphone")) {tomobilevertion ();}
}
})();
function Getrequest () {
var url = location.search; Gets the URL in the "?" String after the character
var therequest = new Object ();
if (Url.indexof ("?")! =-1) {
var str = URL.SUBSTR (1);
STRs = Str.split ("&");
for (var i = 0; i < strs.length; i + +) {
