Jak zalogować się przy użyciu konta Facebook?

Question

Przeszedłem przez this link i wypróbowałem kod.

Robię to samo, ale nie ma odpowiedzi z Facebooka. Brak wyskakującego okienka (niezablokowane). Mój kod jest podany poniżej:

<div id="fb-root"></div> 
<script> 


// Additional JS functions here 


window.fbAsyncInit = function() { 


FB.init({ 

     appId  : 'myappid', // App ID 
     channelUrl : '//myurl/channel.html', // Channel File 
     status  : true, // check login status 
     cookie  : true, // enable cookies to allow the server to access the session 
     xfbml  : true // parse XFBML 
    }); 


FB.getLoginStatus(function(response) { 
alert("Response"); 
alert("getloginstatus"); 
    if (response.status === 'connected') { 
     // connected 
    } else if (response.status === 'not_authorized') { 
     // not_authorized 
     login(); 
    } else { 
     // not_logged_in 
     login(); 
    } 
}); 

}; 


    (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); 
    alert("Lodaed SDK"); 
    }(document)); 

function testAPI() { 
    console.log('Welcome! Fetching your information.... '); 
    FB.api('/me', function(response) { 
     alert("Good to see you, " + response.name + "."); 
    }); 
} 

function login() { 
    FB.login(function(response) { 
     if (response.authResponse) { 
      // connected 
     } else { 
      // cancelled 
     } 
    }); 
} 





</script> 
</div> 

Proszę, powiedz mi, co robię źle. Tak, nie mam żadnego pola wyboru w

 <script> 
     // This is called with the results from from FB.getLoginStatus(). 
     function statusChangeCallback(response) { 
     console.log(response); 
     // The response object is returned with a status field that lets the 
     // app know the current login status of the person. 
     // Full docs on the response object can be found in the documentation 
     // for FB.getLoginStatus(). 
     if (response.status === 'connected') { 
      // Logged into your app and Facebook. 
      testAPI(); 
     } else if (response.status === 'not_authorized') { 
      // The person is logged into Facebook, but not your app. 
      console.log("The person is logged into Facebook, but not your app."); 
     } else { 
      // The person is not logged into Facebook, so we're not sure if 
      // they are logged into this app or not. 
     } 
     } 

     // This function is called when someone finishes with the Login 
     // Button. See the onlogin handler attached to it in the sample 
     // code below. 
     function checkLoginState() { 
     FB.getLoginStatus(function(response) { 
      statusChangeCallback(response); 
     }); 
     } 

     window.fbAsyncInit = function() { 
     FB.init({ 
      appId: '{Your App Id}', 
      cookie: true, // enable cookies to allow the server to access 
      // the session 
      xfbml: true, // parse social plugins on this page 
      version: 'v2.2' // use version 2.2 
     }); 

     // Now that we've initialized the JavaScript SDK, we call 
     // FB.getLoginStatus(). This function gets the state of the 
     // person visiting this page and can return one of three states to 
     // the callback you provide. They can be: 
     // 
     // 1. Logged into your app ('connected') 
     // 2. Logged into Facebook, but not your app ('not_authorized') 
     // 3. Not logged into Facebook and can't tell if they are logged into 
     // your app or not. 
     // 
     // These three cases are handled in the callback function. 

     FB.getLoginStatus(function(response) { 
      statusChangeCallback(response); 
     }); 

     }; 

     // Load the SDK asynchronously 
     (function(d, s, id) { 
     var js, fjs = d.getElementsByTagName(s)[0]; 
     if (d.getElementById(id)) return; 
     js = d.createElement(s); 
     js.id = id; 
     js.src = "//connect.facebook.net/en_US/sdk.js"; 
     fjs.parentNode.insertBefore(js, fjs); 
     }(document, 'script', 'facebook-jssdk')); 

     // Here we run a very simple test of the Graph API after login is 
     // successful. See statusChangeCallback() for when this call is made. 
     function testAPI() { 
     console.log('Welcome! Fetching your information.... '); 
     FB.api('/me', function(response) { 
      console.log("Fb response"); 
      console.log(response); 
      console.log('Successful login for: ' + response.name); 
      document.getElementById('status').innerHTML = 
      'Thanks for logging in, ' + response.name + '!'; 
     }); 
     }
