在安卓 App 分享的时候会调用 toptodayandroid 这个函数

    1. <script type="text/javascript">
    2.     var u = navigator.userAgent, app =  navigator.appVersion;
    3.     var isAndroid = u.indexOf('Android') > -1 ||  u.indexOf('Linux') > -1; //android终端或者uc浏览器
    4.     var isiOS = !!u.match(/\(i[^;]+;( U;)? CPU.+Mac  OS X/); //ios终端
    5.     var isiosapp = u.indexOf('Safari') == -1 &&  u.indexOf('Language') == -1 &&  u.indexOf('MicroMessenger') == -1;
    6.     var isanapp = u.indexOf('igetapp') > -1;
    7.     //判断该页面是否在微信上？
    8.     function is_weixn(){
    9.         var ua = navigator.userAgent.toLowerCase();
    10.         if(ua.match(/MicroMessenger/i)=="micromessenger")  {//alert(1);
    11.             return true;
    12.         } else {//alert(2)
    13.             return false;
    14.         };
    15.     };
    16.     function toptodayandroid(top){
    17.         var bt = "共读训练营";

    33.     //ios显示分享按钮
    34.     if(isiOS&&isiosapp){
    35.         $('.invite').click(function(){
