JS与APP应用交互

JS打开app应用，如果不存在就去下载应用

var APPCommon = {
    iphoneSchema: 'yr-hotblood://',
    iphoneDownUrl: '',
    androidSchema: 'yr-hotblood://',
    androidDownUrl: '',
    openApp: function () {
        var this_ = this;
        //微信
        if (this_.isWeixin()) {
            if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i)) {
                $('.wechat img').attr("src", "images/tips_weixin_ios.png");
            } else {
                $('.wechat img').attr("src", "images/tips_weixin_android.png");
            }
            $(".wechat").css("height", $(window).height());
            $(".wechat").show();
        } else {//非微信浏览器
            var baseUrl = window.location.href.replace(/http:\/\/|https:\/\//, '');
            if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i)) {
                var loadDateTime = new Date();
                window.setTimeout(function () {
                    var timeOutDateTime = new Date();
                    if (timeOutDateTime - loadDateTime < 5000) {
                        window.location = this_.iphoneDownUrl;//ios下载地址
                    } else {
                        window.close();
                    }
                }, 25);
                $('#js_downSrc').attr('href', this_.iphoneDownUrl);
                window.location = this.iphoneSchema + baseUrl;
            } else if (navigator.userAgent.match(/android/i)) {
                try {
                    var appKey=this.androidSchema + baseUrl;
                        openApp(appKey,this.GetQueryString('refresh'));
                } catch (e) {
                }
                $('#js_downSrc').attr('href', this_.androidDownUrl);
            }
        }
    },isWeixin: function () { //判断是否是微信
        var ua = navigator.userAgent.toLowerCase();
        if (ua.match(/MicroMessenger/i) == "micromessenger") {
            return true;
        } else {
            return false;
        }
    },GetQueryString(t){
        var n = new RegExp("(^|&)" + t + "=([^&]*)(&|$)", "i"), e = window.location.search.substr(1).match(n);
        return null != e ? decodeURI(e[2]) : null
    }
};
APPCommon.openApp();
function openApp(appKey,refresh) {
    var isRefresh = refresh; // 获得refresh参数
    if(isRefresh == 1) {return}
    window.location = appKey;
    window.setTimeout(function () {
        window.location.href += '?refresh=1' // 附加一个特殊参数，用来标识这次刷新不要再调用myapp:// 了
    }, 500);
}

注：iphoneSchema、androidSchema 需要开发在app中设置；android 应用不能直接打开，只能通过点击事件触发
