JS to determine whether the client is a mobile phone or PC 2 code

Javascript to determine whether the client is a PC or handheld device, sometimes the project needs to use, very convenient detection, the source of the Oh, a total of two kinds of methods

1. The first kind:

Copy CodeThe code is as follows: function IsPC () {
var useragentinfo = navigator.useragent;
var Agents = ["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;
}

2. The second type:

Copy CodeThe code is as follows: function Browserredirect () {
var suseragent = Navigator.userAgent.toLowerCase ();
var bisipad = Suseragent.match (/ipad/i) = = "ipad";
var Bisiphoneos = Suseragent.match (/iphone os/i) = = "iphone OS";
var BISMIDP = Suseragent.match (/midp/i) = = "MIDP";
var bIsUc7 = Suseragent.match (/rv:1.2.3.4/i) = = "rv:1.2.3.4";
var bisuc = Suseragent.match (/ucweb/i) = = "UCWeb";
var bisandroid = Suseragent.match (/android/i) = = "Android";
var bisce = Suseragent.match (/windows ce/i) = = "Windows CE";
var biswm = Suseragent.match (/windows mobile/i) = = "Windows Mobile";
if (! ( Bisipad | | Bisiphoneos | | BISMIDP | | BIsUc7 | | Bisuc | | bisandroid | | Bisce | | BISWM)) {
Window.location.href=b page;
}
}
Browserredirect ();

Baidu's judgment code

Copy CodeThe code is as follows:
function Uaredirect (f) {
try {
if (document.getElementById ("bdmark") = null) {
Return
}
var B = false;
if (Arguments[1]) {
var e = window.location.host;
var a = window.location.href;
if (Issubdomain (arguments[1], e) = = 1) {
f = f + "/#m/" + A;
B = True
} else {
if (Issubdomain (arguments[1], e) = = 2) {
f = f + "/#m/" + A;
B = True
} else {
f = A;
B = False
}
}
} else {
B = True
}
if (b) {
var c = Window.location.hash;
if (!c.match ("Fromapp")) {
if (Navigator.userAgent.match (/(iphone|ipod| android|ios| SymbianOS))) {
Location.replace (f)
}
}
}
} catch (d) {}
}
function Issubdomain (c, D) {
This.getdomain = function (f) {
var e = F.indexof ("://");
if (E > 0) {
var h = f.substr (e + 3)
} else {
var h = f
}
var g =/^www\./;
if (G.test (h)) {
H = h.substr (4)
}
Return h
};
if (c = = d) {
Return 1
} else {
var C = This.getdomain (c);
var B = This.getdomain (d);
if (c = = b) {
Return 1
} else {
c = C.replace (".", "\ \.");
var a = new RegExp ("\ \" + C + "$");
if (B.match (a)) {
Return 2
} else {
return 0
}
}
}
};

How to use:
<script Type=text/javascript>uaredirect ("Mobile Station", "Web Station");</script>

Another article, feel as good as above, but we can refer to the next

Copy CodeThe code is as follows:
var browser_class = navigator.useragent;
var browser_class_name1 = Browser_class.match ("Mobile");
var browser_class_name2 = Browser_class.match ("mobile");
var location_url = window.location.href;
if (browser_class_name1! = NULL | | Browser_class_name2! = NULL) {
if (Location_url.match ("wap") = = null) {
Window.location.href = "http://wap.xxxx.com";
}
} else {
if (Location_url.match ("3g")! = NULL | | Location_url.match ("WAP")! = null) {
Window.location.href = "http://wap.xxxx.com";
}
}
