Question

I am trying to implement facebook login in my web application. i got the app id and my code is as follows.` My Facebook Login Page

  <div id="fb-root"></div>
  <script>
    window.fbAsyncInit = function() {
      FB.init({
        appId      : '<<App Id>> ', // App ID
        channelUrl : '//www. DOMAIN NAME.com/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
      });
      // Additional initialization code here
    };
    // 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;
