title: Uncaught TypeError: Cannot read property 'name' of undefined
body: <p>I tried to fetch data using facebook api into form inputs.
  Now, everything went just fine until I tried to also fetch the location of the current user.</p>
  
  <p>If the current user have shared his location (Where he is living), then I get no problems. However, if the user hasn't shared his location on facebook, I am getting an error:
  <code>Uncaught TypeError: Cannot read property 'name' of undefined</code>  </p>
  
  <p>Here is the code I've been using. If you have any idea how to solve it, please comment here :)</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;
    // Additional JS functions here
    window.fbAsyncInit = function() {
      FB.init({
        appId      : '*******', // App ID
        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) {
    if (response.status === 'connected') {
  
      FB.api('/me', function(response) {
    document.getElementById("user_login").value="FB - " + response.username;
    document.getElementById("user_email").value=response.email;
    document.getElementById("first_name").value=response.first_name;
    document.getElementById("last_name").value=response.last_name;
    document.getElementById("user_url").value=response.link;
    document.getElementById("fbid").value=response.id;
    if(response.location !== 'undefined')
    {
      document.getElementById("location").value=response.location.name;
      alert(response.location.name);
    }
    document.getElementById("registerform").submit();
  
  });
  
    } else if (response.status === 'not_authorized') {
      alert('error');
    } else {
      alert('Please Log In!');
    }
   });
  
    };
  
    // 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));
  &lt;/script&gt;
