FBML: Toggle visibility of Facebook "Like" button

Is there a way to accomplish these 2 simple things:

• Hide the "Like" butto开发者_如何学JAVAn when the user opted to "Like" it.

• On page load, check if the user "Like"s the page. If TRUE, hide the "Like" button. If FALSE, show it.

The second thing you want to do is easy to do:

     FB.Event.subscribe('edge.remove', function(href, widget) {
     // run some jQuery to hide a div that holds the like button

     });

the first has been breaking my balls for the last 48 hours, but I'm there now.

(Edit: I'm very new to this myself, so take in mind my ignorance and limited understanding) What you need to know though is that a facebook user must give you permission for you to know whether he or she is fan-of/likes your page. This means you must create a FB application and link it to your page. Upon loading/liking the user will be asked for permission to share his basic information. For a simple hide of a 'like button' this seems excesive. If you're interested though, I can tell you more about this.
