js判断客户端是pc端还是移动端

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){}
    }
}
