            if (response.status === 'connected') {
                getElementById('status').innerHTML = 'we are connected.';
            } else if (response.status === 'not authorized') {
                document.getElementById('status').innerHTML = 'we are not logged in.'
            } else {
                document.getElementById('status').innerHTML = 'you are not logged into facebook.';
            }
        });
    }

Answer 1

代码似乎存在多个问题

1. 您第一次调用getElementById是一个错误。你应该在文档对象上调用它。
2. 添加a）;最后

您的代码看起来像

(function login() {
    FB.login(function(response) {
        if (response.status === 'connected') {
            document.getElementById('status').innerHTML = 'we are connected.';
        } else if (response.status === 'not authorized') {
            document.getElementById('status').innerHTML = 'we are not logged in.'
        } else {
            document.getElementById('status').innerHTML = 'you are not logged into facebook.';
        }
    });
});
