ajaxフォームからのリダイレクションクライアント側からの送信

Question

こんにちは、私はnodejsとajaxを初めて使っていて、データベースにフォームを送信してからセッション変数を設定し、別のページにリダイレクトします。クライアント側のajaxコードは

<script type='text/javascript'> 
         /* attach a submit handler to the form */ 
         $("#comp").submit(function(event) { 

          /* stop form from submitting normally */ 
          event.preventDefault(); 

          /* get some values from elements on the page: */ 
          var $form = $(this), 
          url = $form.attr('action'); 

          /* Send the data using post */ 
          var posting = $.post(url, { N1: $('#N1').val(), N2: $('#N2').val(), N3: $('#N3').val(), N4: $('#N4').val() 
          , N5: $('#N5').val(), N6: $('#N6').val(), N7: $('#N7').val(), N8: $('#N8').val(), N9: $('#N9').val() }); 

          /* Alerts the results */ 
          posting.done(function(data) { 
          alert('success'); 
          window.location.assign("localhost:3000/User_Creation"); 
          }); 


         }); 
        </script> 

と私のサーバー側のコードは以下の通りです。これは正しい方法であるかどうかわかりませんが、これを間違った方法でやっているのですか？どこが間違っていますか

URLの先頭にhttpを追加します。

window.location.assign("http://localhost:3000/User_Creation");
