How can I auto fresh when a button is clicked?

How can I determine who has clicked Facebook like button and then not display like button to him?

• I am working on facebook application. I have put like widget on one of the page. I don't want to show like button, if user has already clicked like button. How can this be done ?

• Answer:

  If the user has authorized your application to access their information, you can do it with the pages.isFan api call: http://developers.facebook.com/docs/reference/rest/pages.isFan If you're using FBML, you can use fb:visible-to-connection: http://developers.facebook.com/docs/reference/fbml/visible-to-connection If it's a Like button on an external site, you could try the suggestion posted in this stackoverflow thread to register a javascript callback for edge.create: http://stackoverflow.com/questions/2798622/facebook-like-button-callback In your javascript callback function, you could set a cookie and then not render the like button next time around if that cookie exists.
