friend-selector : get user ID of the selected friend

I need to create a graphical interface that displays the current user's friends and when you click one of these users need to receive in return the ID of the user so they can perform some processing based on business rule of my application. I wonder if there is any component that offers this functionality (click on a friend and get the id of my friend).

When I say "c开发者_开发知识库omponent" I mean the UI's such as friend-selector: http://developers.facebook.com/docs/reference/fbml/friend-selector/ Thanks

There are NO official plugin to do this. You need to:

1. Build your own (won't be hard at all)
2. Try googling for existing ones
