Login Module Facebook button

Hi there !

I am doing a custom modification of the login module 2.0.3 for myself. Since I am not that familiar with fb Connect maybe you can give me a hint:

I would like to ask a confirmation message "Are you sure that you want to connect to Facebook" .... so I changed the login code like this:

When I click on the button the confirm message is asked properly ... but even if it returns false it will not prevent the opening of the Facebook Connect window ? What did I wrong ? Thank you for any hints ....

That's not really a javascript call within those <fb> tags. Normal javascript wouldn't work there (it works for the onlogin thing because that's how Facebook's API works). I don't know of any good way to do what you're asking, unfortunately, because Facebook specifies what you can and can't do within those <fb> tags.
