js自动判断访问设备

一、

F12（手机）模式下处于非手机

//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);
if (system.win || system.mac || system.xll) {} else {
    //手机设备的情况
    setTimeout(function(){
            window.location.href = "http://bd.rtkgyo.com/";
        }, 6000)
}

二、

开发者F12（手机）模式下处于手机（个人感觉不太真实）

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)) {
        console.log("手机")
    }
}
browserRedirect();
