单击引导模式

Question

我有以下模式，当用户点击提交时，我想重定向到另一个页面。

我的HTML代码：

 <!-- Modal -->
       <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">
         <div class="modal-content">
         <div class="modal-header">
           <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
           <h4 class="modal-title">Add new card</h4>
          </div>
           <form action="addCard" method="post" id="addcard" class="form-horizontal" role="form">
           <div class="modal-body" style="height: 190px;">
             <div class="form-group" style="height: 30px;">
            <label for="title" class="col-md-3 control-label">Title</label>
            <div class="col-md-9">
               <input type="text" class="form-control" name="title" placeholder="Enter Card title here...">
              </div>
           </div>
           <div class="form-group" style="height: 30px; margin-bottom:30px;">
            <label for="title" class="col-md-3 control-label">Description</label>
            <div class="col-md-9">
               <textarea class="form-control" name="desc" placeholder="Enter Card description here..."></textarea>
            </div>
           </div>
           <div class="form-group">
            <label for="priority" class="col-md-3 control-label">Priority</label>
            <div class="col-md-9">
               <select name="priority" class="form-control">
                <option value="critical">Critical</option>
                <option value="high">High</option>
                <option value="normal">Normal</option>
                <option value="low">Low</option>
                </select>
              </div>
            </div>
          </div>
          <div class="modal-footer">
             <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
              <button type="button" class="btn btn-primary" id="formSubmit" type="submit">Submit</button>
          </div>
          </form>
         </div><!-- /.modal-content -->
        </div><!-- /.modal-dialog -->
        </div><!-- /.modal -->

app.js：

app.post('/addCard', routes.addCard);

index.js：

 exports.addCard = function (req,res)
  {
 res.render('index'); 
  }

当我点击＆＃39;提交＆＃39;莫代尔的按钮，没有动作发生。请指教。感谢。
