Question

let openApp = function () {
            var u = navigator.userAgent;
            var isWeixin = u.toLowerCase().indexOf('micromessenger') !== -1; // 微信内
            var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Linux') > -1; //android终端
            var isIOS = !!u.match(/(i[^;]+;( U;)? CPU.+Mac OS X/); //IOS终端
            // 微信内
            if (isBlackApp()) {
                alert('请在浏览器上打开')
            } else {
                //android端
                if (isAndroid) {
                    //安卓app的scheme协议
                    window.location.href = 'xxx://';

                            .msHidden || window.document.webkitHidden
                        if (typeof hidden == "undefined" || hidden == false) {
                            //应用宝下载地址 (emmm 找不到淘宝应用宝的地址，这里放的是 lucky coffee 地址)
                            window.location.href =
