I don't think you can do this. This is running on the user's machine. The user can always change it to get what he wants.
You cannot do this completely. Javascript is a client side scripting language If user has disabled the javascript than he/she will be able to click . You should be user friendly.
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.
