title: FB.Event.subscribe like button
body: <p>I'd like to know how replace <em>('like '+href)</em> with a custom hyperlink.
  For example: "thank you to like us. Visit example.com"
  </p>
  
  <pre><code>&lt;html&gt;
  &lt;body&gt;
   &lt;fb:like href="http://www.example.com/" show_faces="true" width="450"&gt;&lt;/fb:like&gt;
   &lt;div id="fb-root"&gt;&lt;/div&gt;
   &lt;script src="http://connect.facebook.net/it_IT/all.js#xfbml=1"&gt;&lt;/script&gt;
   &lt;script&gt;
     FB.Event.subscribe('edge.create', function(href, widget) {
       alert('like '+href);
     });
     FB.Event.subscribe('edge.remove', function(href, widget) {
       alert('dislike '+href);
     });
   &lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
