  <script> 
    window.fbAsyncInit = function() { 
    FB.init({ 
    appId  : '645304363653fghdfg', // App ID 
    channelUrl : '//WWW.channelUrl .com', // Channel File 
    status  : true, // check login status 
    cookie  : true, // enable cookies to allow the server to access the session 
    xfbml  : true // parse XFBML 
     }); 

    // Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired 
    // for any authentication related change, such as login, logout or session refresh. This means that 
     // whenever someone who was previously logged out tries to log in again, the correct case below 
    // will be handled. 
     FB.Event.subscribe('auth.authResponseChange', function(response) { 
    // Here we specify what we do with the response anytime this event occurs. 
    if (response.status === 'connected') { 
    // The response object is returned with a status field that lets the app know the current 
    // login status of the person. In this case, we're handling the situation where they 
    // have logged in to the app. 
    testAPI(); 
    } else if (response.status === 'not_authorized') { 
    // In this case, the person is logged into Facebook, but not into the app, so we call 
    // FB.login() to prompt them to do so. 
    // In real-life usage, you wouldn't want to immediately prompt someone to login 
    // like this, for two reasons: 
    // (1) JavaScript created popup windows are blocked by most browsers unless they 
    // result from direct interaction from people using the app (such as a mouse click) 
    // (2) it is a bad experience to be continually prompted to login upon page load. 
    FB.login(); 
    } else { 
    // In this case, the person is not logged into Facebook, so we call the login() 
    // function to prompt them to do so. Note that at this stage there is no indication 
    // of whether they are logged into the app. If they aren't then they'll see the Login 
    // dialog right after they log in to Facebook. 
    // The same caveats as above apply to the FB.login() call here. 
    FB.login(); 
    } 
    }); 
    }; 

    // Load the SDK asynchronously 
(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 = "//connect.facebook.net/en_US/all.js"; 
ref.parentNode.insertBefore(js, ref); 
}(document)); 

// Here we run a very simple test of the Graph API after login is successful. 

// This testAPI() function is only called in those cases. 
function login() { 
FB.login(function(response) { 
    if (response.authResponse) { 
     // connected 
    testAPI(); 
    } else { 
     // cancelled 
    } 
    }, { scope: 'email'/'phone' }); 
    } 
function testAPI() { 
console.log('Welcome! Fetching your information.... '); 
FB.api('/me', function(response) { 
    console.log('Good to see you, ' + response.name + '.' + ' Email: ' + response.email + ' Facebook ID: ' + response.id); 
    //console.log('Good to see you, ' + response.name + '.'); 



    }); 
    } 

    </script> 




    <fb:login-button show-faces="false" width="200" max-rows="1" scope="email" onclick="testAPI();" onlogin="Log.info('onlogin callback')"> 
    Login with Facebook
