第一步：添加js

$(function () {
    var ua = window.navigator.userAgent.toLowerCase();
    //微信
    if(ua.match(/MicroMessenger/i) == ‘micromessenger‘){
　　　　　//微信浏览器绑定事件
        /*$(".app").bind(‘click‘, function (event) {
         window.location.href = http://www.mamicode.com/‘‘;
         })*/
    }else{//非微信浏览器
        if (navigator.userAgent.match(/(iPhone|iPod|iPad);?/i)) {   //iPhone|iPod|iPad浏览器

            $(".app").bind(‘click‘, function (event) {
                var loadDateTime = new Date();
                window.setTimeout(function () {
                    var timeOutDateTime = new Date();
                    if (timeOutDateTime - loadDateTime < 5000) {
                        window.location = "http://itunes.apple.com/app/1219885292";//ios下载页面
                    } else {
                        window.close();
                    }
                }, 25);
                window.location = "YuWan://com.YuWan.DianJingPingTai";    //调用ios启动页地址
            })
        }else if (navigator.userAgent.match(/android/i)) {  //安卓浏览器
            $(".app").bind(‘click‘, function (event) {
                var state = null;
                try {
                    window.location = ‘appshare://bluemobi.cn.esport‘; //调用andriod启动页地址

                    setTimeout(function(){
                        window.location= "download.html"; //android下载页面

                    },500);
                } catch(e) {}
            })
        }

    }
})
