在django中上传文件完成后，我可以创建一个弹出窗口吗

from django.http import HttpResponse

def upload_file(request):
    # 处理文件上传逻辑
    # ...

    # 返回包含JavaScript代码的HttpResponse
    return HttpResponse('''
        <script>
            window.open('/popup/', '_blank', 'width=500,height=500');
        </script>
    ''')

from django.http import HttpResponse

def upload_file(request):
    # 处理文件上传逻辑
    # ...

    # 返回包含模态框HTML代码的HttpResponse
    return HttpResponse('''
        <div id="myModal" class="modal">
            <div class="modal-content">
                <span class="close">&times;</span>
                <p>This is a modal window.</p>
            </div>
        </div>

        <script>
            // 显示模态框
            document.getElementById('myModal').style.display = 'block';

            // 关闭模态框
            document.getElementsByClassName('close')[0].onclick = function() {
                document.getElementById('myModal').style.display = 'none';
            }
        </script>
    ''')
