    (function (d) {

        var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];

        if (d.getElementById(id)) { return; }

        js = d.createElement('script'); js.id = id; js.async = true;

        js.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';

        ref.parentNode.insertBefore(js, ref);

    var called = false;

    window.fbAsyncInit = function () {

        FB.init({
            appId: 'XXXX', // App ID           
            status: true, // check login status

        });

        alert("12");
        FB.getLoginStatus(function (response) {

            if (response.status === 'connected') {
                alert("Your UID is " + response.authResponse.userID);
            }
