JS判斷pc mobile幾種方式

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 {//移動終端瀏覽器版本信息   
                trident: u.indexOf('Trident') > -1, //IE內核  
                presto: u.indexOf('Presto') > -1, //opera內核  
                webKit: u.indexOf('AppleWebKit') > -1, //蘋果、谷歌內核  
                gecko: u.indexOf('Gecko') > -1 && u.indexOf('KHTML') == -1, //火狐內核  
                mobile: !!u.match(/AppleWebKit.*Mobile.*/), //是否爲移動終端  
                ios: !!u.match(/\(i[^;]+;( U;)? CPU.+Mac OS X/), //ios終端  
                android: u.indexOf('Android') > -1 || u.indexOf('Linux') > -1, //android終端或者uc瀏覽器  
                iPhone: u.indexOf('iPhone') > -1 , //是否爲iPhone或者QQHD瀏覽器  
                iPad: u.indexOf('iPad') > -1, //是否iPad    
                webApp: u.indexOf('Safari') == -1, //是否web應該程序，沒有頭部與底部  
                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：（推薦，摘自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  
     };  
}();
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="手機頁面";  
            }else if(/iPad/i.test(navigator.userAgent)){  
                window.location.href="平板頁面";  
            }else{  
                window.location.href="其他移動端頁面"  
            }  
        }catch(e){}  
    }  
}  

方法五：

//平臺、設備和操作系統    
var system ={    
win : false,    
mac : false,    
xll : false    
};    
//檢測平臺    
var p = navigator.platform;    
system.win = p.indexOf("Win") == 0;    
system.mac = p.indexOf("Mac") == 0;    
system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);    
//跳轉語句，如果是手機訪問就自動跳轉到caibaojian.com頁面    
if(system.win||system.mac||system.xll){    
}else{    
window.location.href="http://caibaojian.com";    
}    

方法六：

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爲你所需跳轉目標頁地址  
 }

   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]);  
      }  
   }  
   return theRequest;  
}
