<h2>Updated JS SDK example</h2><br />
<div id="user-info"></div>
<p><button id="fb-auth">Login</button>
<label id="lbemail"  runat="server"></label>
 </p>

<script type="text/javascript">
    window.fbAsyncInit = function () {
        FB.init({ appId: ''API'',
            status: true,
            cookie: true,
            xfbml: true,
            oauth: true
        });

        function updateButton(response) {
            var button = document.getElementById(''fb-auth'');
            var email = document.getElementById(''lbemail'');
            if (response.authResponse) {
                //user is already logged in and connected
                var userInfo = document.getElementById(''user-info'');
                FB.api(''/me'', function (response) {
                    userInfo.innerHTML = ''<img src="https://graph.facebook.com/''
	  + response.id + ''/picture">'' + response.name + response.user_location;
                    email.innerHTML = response.email;
                    button.innerHTML = ''Logout'';


                });
                button.onclick = function () {
                    FB.logout(function (response) {
                        var userInfo = document.getElementById(''user-info'');
                        userInfo.innerHTML = "";
                    });
                };
            } else {
                //user is not connected to your app or logged out
                button.innerHTML = ''Login'';
                button.onclick = function () {
                    FB.login(function (response) {
                        if (response.authResponse) {
                            FB.api(''/me'', function (response) {
                                var userInfo = document.getElementById(''user-info'');
                                userInfo.innerHTML =
                ''<img src="https://graph.facebook.com/''
	        + response.id + ''/picture" style="margin-right:5px"/>''
	        + response.name;
                            });
                        } else {
                            //user cancelled login or did not grant authorization
                        }
                    }, { scope: ''email'' });
                }
            }
        }

        // run once with current status and whenever the status changes
        FB.getLoginStatus(updateButton);
        FB.Event.subscribe(''auth.statusChange'', updateButton);
    };

    (function () {
        var e = document.createElement(''script''); e.async = true;
        e.src = document.location.protocol
    + ''//connect.facebook.net/en_US/all.js'';
        document.getElementById(''fb-root'').appendChild(e);
    } ());

</script>
