Django与AJAX实现网页动态数据显示的示例代码

from django.http import JsonResponse

def data_fresh(request):
  context = {"data1": Test.objects.order_by("-time")[0].temp1,
        "data2": Test.objects.order_by("-time")[0].temp2}
  return JsonResponse(context)

urlpatterns = [
  path('data_fresh/', views.data_fresh, name="data_fresh"),
]

<script>
  $(document).ready(function(){
    function refresh(){
      $.getJSON("/data_fresh/", function (ret) {
        $('#result').html(ret.data1);
        $('#result2').html(ret.data2);
      })
    }
    setInterval(refresh, 3000)
  })
</script>
