检测页面是在移动端还是PC端打开的方法总结

• Navigator对象

  在介绍方法之前，先了解下Navigator 对象，Navigator对象包含有关浏览器的信息，下面的userAgent 属性是一个只读的字符串，声明了浏览器用于 HTTP 请求的用户代理头的值。实际上就是利用正则去判断 navigator.useragent 是否含有 Android/webOs/iphone 等字符串，并且利用修饰符 "i" 做了不区分大小写，然后用正则的方法 test 去判断是否满足，或者利用字符串的 indexOf 方法做判断。

• 方法1：

    function IsPC() {
       var userAgentInfo = navigator.userAgent;
       var Agents = ["Android", "iPhone","SymbianOS", "Windows Phone", "iPad", "iPod"];
       var flag = true;
       for (var i = 0; i < Agents.length; i++) {
              if (userAgentInfo.indexOf(Agents[i]) > 0) {
                   flag = false;
                   break;
              }
       }
       return flag;
     }
     if(IsPC()==true) {
        window.location.href = "http://www.zhenglinglu.cn/pc/"; pc站地址
     } else {
        window.location.href = "http://www.zhenglinglu.cn/move/"; 移动端地址
     }

• 方法2：

    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) ){
          /*执行语句，比如：window.location.href=http://www.zhenglinglu.cn */
        }
    }
browserRedirect();

• 方法3：

    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
  }
 }
 }
};

使用方法：
<script type=text/javascript>uaredirect("手机站地址","WEB站地址");</script >
