I’m new to the facebook api, but I have this:
<html>
<head>
<title>My Facebook Login Page</title>
</head>
<body>
<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({
appId:'my_app_id', cookie:true,
status:true, xfbml:true
});
</script>
<fb:login-button perms="email">Login</fb:login-button>
</body>
