Xfbml: true, // parse XFBML
Oauth: true
});

[Javascript]
Function Test (){
// FB. api ('/me', function (response ){
// Alert ('your name is '+ response. name );
//});
FB. login (function (response ){
If (response. authResponse ){
Alert ('Welcome! Fetching your information ....');
FB. api ('/me', function (response ){
Alert ('Good to see you, '+ response. name + '.');
});
} Else {
Alert ('user canceled login or did not fully authorize .');
