未捕獲的語法錯誤輸入（Java腳本）

Question

最後一行的意外結束是顯示錯誤

(function login() { 
     FB.login(function(response) { 
      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

似乎與代碼

1. 你來的getElementById第一個電話是一個錯誤多個問題。你應該在文檔對象上調用它。
2. 添加a）;在結束

您的代碼看起來像

(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.'; 
     } 
    }); 
});
