Js判断客户端是否为PC还是手持移动设备

Js判断客户端是否为PC还是手持移动设备

方法一

 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";
 };

方法二

 var browser={
     versions:function(){
            var u = navigator.userAgent, app = navigator.appVersion;
            return {//移动终端浏览器版本信息
                 trident: u.indexOf('Trident') > -1, //IE内核
                 presto: u.indexOf('Presto') > -1, //opera内核
                 webKit: u.indexOf('AppleWebKit') > -1, //苹果、谷歌内核
                 gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐内核
                 mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否为移动终端
                 ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios终端
                 android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android终端或者uc浏览器
                 iPhone: u.indexOf('iPhone') > -1 , //是否为iPhone或者QQHD浏览器
                 iPad: u.indexOf('iPad') > -1, //是否iPad
                 webApp: u.indexOf('Safari') == -1, //是否web应该程序，没有头部与底部
                 weixin: u.indexOf('MicroMessenger') > -1, //是否微信
                 qq: u.match(/\sQQ/i) == " qq" //是否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";
   }

方法三： 摘自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
      };
 }();

使用方法 

if(os.isAndroid || os.isPhone){

alert("-----");

}

方法四：

 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="手机页面";
             }else if(/iPad/i.test(navigator.userAgent)){
                 window.location.href="平板页面";
             }else{
                 window.location.href="其他移动端页面"
             }
         }catch(e){}
     }
 }

方法五

 <script language="javascript">
 //平台、设备和操作系统
 var system ={
 win : false,
 mac : false,
 xll : false
 };
 //检测平台
 var p = navigator.platform;
 system.win = p.indexOf("Win") == 0;
 system.mac = p.indexOf("Mac") == 0;
 system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
 //跳转语句，如果是手机访问就自动跳转到caibaojian.com页面
 if(system.win||system.mac||system.xll){
 }else{
 window.location.href="http://caibaojian.com";
 }

方法六

 <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';  //修改http://caibaojian.com为你所需跳转目标页地址
  }

     var res = GetRequest();
     var par = res['index'];
     if(par!='gfan'){
         var ua=navigator.userAgent.toLowerCase();

 function GetRequest() {
    var url = location.search; //获取url中"?"符后的字串
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
       var str = url.substr(1);
       strs = str.split("&");
       for(var i = 0; i < strs.length; i ++) {
          theRequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
