当引导模式关闭并重新打开时，如何重置该模式？

我在引导模态中有一个列表框和一个按钮。单击按钮后，新的按钮将在模态的div内渲染。当我关闭模态并重新打开它时，模态上执行的最后一个操作（如先前呈现的按钮）仍然存在于模态中。

如何重置模态，以便再次打开模态时，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>

为什么不起作用？

              <script type="text/javascript">  
                $(function(){  
                      $('#myModal').on('hidden.bs.modal', function (e) {
                      console.log("Modal hidden");
                      $("#placeholder-div1").html("");
                    });
                });
              </script>

回答：

隐藏模态后，只需手动重置任何内容即可：

$(".modal").on("hidden.bs.modal", function(){
    $(".modal-body1").html("");
});
$(document).ready(function() {
  $(".modal").on("hidden.bs.modal", function() {
    $(".modal-body1").html("Where did he go?!?!?!");
  });
});

      <div class="modal-body">

          <h3>Close and open, I will be gone!</h3>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
