js判断客户端是PC端还是移动端访问

js判断客户端是PC端还是移动端访问

方法一 (推荐）

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";  
}  
</script>

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
 }
