模式不显示，但单击按钮时出现灰色背景

Question

我有一个动态创建的表，每行显示的单击查看按钮都会显示一个灰色屏幕，但模型无法打开..我尝试了很多，但不了解问题所在。我使用了https： //simpleisbetterthancomplex.com/tutorial/2016/11/15/how-to-implement-a-crud-using-ajax-and-json.html他的代码作为参考。

请帮我...

m_manage.html ---这里我声明了模式并包含了页面

---

<div class="panel-body">
 <table class="table table-hover" id="table">                      
   <tbody>
      {% include 'm_manage/partial_m_manage.html' %}
   </tbody>
 </table>
</div>              
<div class="modal fade" id="modal-leave">
  <div class="modal-dialog">
   <div class="modal-content">
 </div>
</div>

partial_m_manage.html：它包含表中的列

---

{% for  pl in pending_leaves %}
<tr> 
  <td><button type="button" class="btn btn-default btn-sm view" data-url="{% url 'm_manage:leave_view' pl.id %}" data-target="#{{pl.id}}_3"><i class="fa fa-eye" aria-hidden="true" style="color:black"></i></button>                                        
   </td>                                   
</tr>
{% endfor %}

js ----单击按钮即可调用

    $("#table").on('click', '.view', function (e) {
    var btn = $(this);
    console.log(btn);
    var url= btn.attr("data-url");
    console.log(url);
    $.ajax({
      // url: '/m_manage/leave_view/', 
      url: btn.attr("data-url"),
      dataType: 'json',
      type: 'get',

      beforeSend: function () {
       $("#modal-leave").modal("show");
      },
      success: function (data) {
        console.log('You Did it!!!!');
        $("#modal-leave .modal-content").html(data.html_form);
      }
    });
  });

views.py--

---

def leave_view(request,pk):
  Leave = get_object_or_404(leave, pk=pk);
  data=dict()
  if request.method == 'POST':
     data['html_form']= render_to_string('m_manage/view_modal.html',{'Leave':Leave}, request=request)
return JsonResponse(data)

view_modal.html ---我正在渲染一个新页面，即模式

<form method="post" action="{% url 'm_manage:leave_view' Leave.id %}" class="js-leave-view-form">
{% csrf_token %}
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
    <h4 class="modal-title">Do you want to accept {{Leave.id}} leave</h4>
  </div>
  <div class="modal-body"> 
  <h1>aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</h1>
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary">Create book</button>
  </div>
  </form>

但是会出现黑屏，并且所有值都可以在控制台中成功打印，但不会出现模式弹出窗口...

请帮我... ：（

您应该包括“ bootstrap.min.css”。
