title: Callback URL for digg button
body: <p>I am working on a website where the client has asked me to implement a functionality where a part of the content is shown to the end user once the page is liked by the end user on Facebook or the user had clicked on digg share button. </p>
  
  <p>I have implemented a callback successfully which shows the content after the facebook button is liked. The way I did it is like this:</p>
  
  <pre><code>&lt;div id='fb-root' style=''&gt;&lt;/div&gt; &lt;fb:like href='URL to like' show_faces='false' border_color='' stream='false' header='false'&gt;&lt;/fb:like-box&gt;&lt;script type='text/javascript'&gt;
  
           window.fbAsyncInit = function() {
          FB.init({appId: 'APP ID', status: true, cookie: true, xfbml: true});
          FB.Event.subscribe('edge.create',
              function(response) {
  
          alert ('You clicked the facebook button');
  
  
          // Other javascript to be executed can be placed here.          
  
  
              }
          );
  
      };
  
  
      (function() {
          var e = document.createElement('script'); e.async = true;
              e.src = document.location.protocol +
                '//connect.facebook.net/en_US/all.js';
              document.getElementById('fb-root').appendChild(e);
      }());
  &lt;/script&gt;
  </code></pre>
  
  <p>The alert in the above code only gets executed when the callback confirms that the user has clicked the facebook like button.</p>
  
  <p>I am trying to do something similar with Digg as well. I searched there API but I was not able to find a solution to such problem.</p>
  
  <p>In simple words I want to know if there is a callback which confirms that the user has clicked the diggshare button ?</p>
  
  <p>Thanks and any help would be appreciated.</p>
