About APP common tests

Detect whether the device, WeChat platform and app are installed

// 检测是否安装了APP
var isappinstalled = (function () {
        return (location.search.indexOf("isappinstalled=1") !== -1);
    }()),
    
    // 检测ios设备
    isIOS = (function () {
        return (navigator.userAgent.search(/iphone|ipad|ipod/i) !== -1);
    }()),

    // 检测微信平台
    isWeiXin = (function () {
        return (navigator.userAgent.toLowerCase().indexOf("micromessenger") !== -1);
    }());

Distinguish between computers and handheld devices through device platforms

// 通过平台检测是否为PC端
var isPC = (function () {

    var system = {
        win: false,
        mac: false
    };
    var p = navigator.platform;


    system.win = p.indexOf("Win32") === 0;
    system.mac = p.indexOf("Mac") === 0;

    // iphone ipad ipod 的平台检测为 IOS

    // 小米手机用的是Xll或Linux系统平台
    // system.x11 = (p == “X11”) || (p.indexOf(“Linux”) == 0);

    if (system.win || system.mac) {
        return true;
    } else {
        return false;
    }
}());

if (isPc) {
    // go to pc web
} else {
    // go to mobile wap
}
