1、第一種：
複制代碼代碼如下:
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、第二種：
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頁面;
browserRedirect();
百度的判斷代碼
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)
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
c = c.replace(".", "\\.");
var a = new RegExp("\\." + c + "$");
if (b.match(a)) {
return 2
return 0
}
};
使用方法：
<SCRIPT type=text/javascript>uaredirect("手機站","WEB站");</SCRIPT>
另外一篇，感覺不如上面的好，不過大家可以參考下
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) {
