我创建了一个模型表单,但是在页面中,它只能显示表单,但是在点击"提交"之后无法输入数据而没有响应。按钮。我的观点或模板有什么问题吗?

打开页面时没有错误提示。

感谢您的帮助。

views.py

from django.http import JsonResponse

class ResultView(ListView):
    context_object_name = 'result_list'
    template_name = 'result_list.html'

     # /URL-to-ajax-view/
    def ajax_get_queryset(request):
        if self.request.method == 'POST' and request.is_ajax:

            form = InputForm(self.request.POST or None)
            if form.is_valid():
                company = form.cleaned_data['company']
                region = form.cleaned_data['region']

                queryset=Result.objects.filter(company=company,region=region)
                sales=Result.objects.queryset.aggregate(Sum('sales'))

            return render(request, 'dupont', {'sales': sales,'region':region,'queryset': queryset})
    else:
        form=InputForm()

我在您的代码中发现了一个小错误:

if self.request.method == 'POST' and request.is_ajax():

应该是

{{1}}

请注意()

另外:将按钮从提交更改为按钮。

您的表单被html中的绝对定位元素所遮蔽。 尝试将此添加到您的CSS:

form{ position:absolute;z-index:100 }

这会将你的表格提升到阴影之上。
