我在bootstrap模式中有一个列表框和一个按钮.单击该按钮时,将在模式中的div内呈现新按钮.当我关闭模态并重新打开它时,在模态上执行的最后一个操作(如前面渲染的按钮)仍然存在于模态中.

如何重置模态,以便当再次打开模态时,按钮不存在,用户可以再次从列表框中选择选项,然后单击按钮以呈现新按钮,依此类推.

        <!-- 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"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
                <h4 class="modal-title" id="myModalLabel">Select Language</h4>
              </div>
              <div class="modal-body">                

                <button type="button" class="btn" data-dismiss="modal">Close</button>                    
                <button type="button" class="btn" id="submit_form">Submit</button>

              <div class="modal-body1">
                <div id="placeholder-div1">
                </div>                    
              </div>

              </div>

              <div class="modal-footer">


              <script>                    
                $('#submit_form').on('click', function() {
                    $(".modal-body1").html('<h3>test</h3>');
                });                                    
              </script>

              <script>                    
                $(function(){                    
                    $('.modal-footer').click(function() {
                       $('.modal').modal('hide');        
                    });                          
                }); 
              </script>

              </div>

            </div>
          </div>
        </div>

为什么这不起作用？

              <script type="text/javascript">  
                $(function(){  
                      $('#myModal').on('hidden.bs.modal', function (e) {
                      console.log("Modal hidden"); …
