2 codes for JS to determine whether the client is a mobile phone or a PC_javascript skills

1. The first type:

Copy code The 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 code The 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) ){
                                                                                                                                                                                              | >

Copy code
The 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)/i))) {
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 site", "WEB site");</SCRIPT>

Another article, I don’t feel as good as the above one, but you can refer to it

Copy the code The 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";
}
}
