您可以使用FB.getLoginStatus作爲建議here它可以告訴你天氣訪問者登錄到Facebook，如果是的話，如果他們已註冊與您的應用程序。

FB.getLoginStatus(function(response) { 
    if (response.status === 'connected') { 
    // the user is logged in and has authenticated your 
    // app, and response.authResponse supplies 
    // the user's ID, a valid access token, a signed 
    // request, and the time the access token 
    // and signed request each expire 
    var uid = response.authResponse.userID; 
    var accessToken = response.authResponse.accessToken; 
    } else if (response.status === 'not_authorized') { 
    // the user is logged in to Facebook, 
    // but has not authenticated your app 
    } else { 
    // the user isn't logged in to Facebook. 
    } 
});
