Answer 1

If you need to work with facebook from your server, you can't use just js auth.

You need to implement "server login", described at Login for Server-side Apps

You need not implement all that complicated things, just find any library from internet, FB have its own library for php as I know, and use it to make server login. You can find many examples how to do it.

You can done with it by using jQuery.ajax() or jQuery.post() function. but it is not secured. Because js is open for all browser. Bad guys can send unexpected data and take chances to harm your app / web. Anyway it is your choice.

You can add a function here i have used replace_login() in FB.getLoginStatus() as following:

FB.getLoginStatus(function(response) {
        if (response.status === 'connected') {
            // connected
    replace_login();
        } else if (response.status === 'not_authorized') {
            // not_authorized
        } else {
            // not_logged_in
        }
    });

Now write replace_login() in same file and after FB.getLoginStatus() as below:

function replace_login(){
       FB.api('/me', function(response) {
          $.post("http://yourdomain.com/ajax_post_login",{ username: response.username, name: response.name, fb_res: response }, function(data) {
              alert(data);
          })
       });
  }
