Facebook Login · 4 - Putting it all together — Facebook Read Eval Log Loop

<h1>Putting it all together</h1>

<p>This example shows you a fairly complete login system implemented using the JavaScript SDK, with the end result being a simple API call that prints your name. You can see how the response from the auth.statusChange event can be used to determine whether someone is logged in or not.</p>

<h2>The Login Example</h2>

<div id="accountInfo" style="padding-top: 20px">You haven't logged in yet.</div>

function showAccountInfo() {
    FB.api('/me?fields=name,picture', function(response) {
      Log.info('API response', response);
      document.getElementById('accountInfo').innerHTML = ('<img src="' + response.picture.data.url + '"> ' + response.name);
    });
    document.getElementById('loginBtn').style.display = 'none';
  }
</script>
