Can I get the same information in the Facebook “Like” button via the JavaScript SDK?

Your constraint is unfortunate, as you'll need an access_token for FQL queries. If the user is logged in on the parent frame then you may be able to pull the access_token from there, but otherwise it's not going to work.

I know that you can catch "Like" and "Unlike" event when user clicks it.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
