javascript - 尝试访问 json 数据时未定义 (ajax)

Question

当我试图从 ajax 访问由 django View 发送的数据时，我得到了未定义的信息

django View :

def GetTenders(request):
print request.POST
if request.method == 'POST':
    print request.POST.get('Page')
    page_num = int(request.POST.get('Page'))
    if page_num != 1:
        start = (page_num - 1) * 4
        objs = Tender.objects.all()[start:(start + 4)]
        return HttpResponse(serializers.serialize('json', objs), content_type='application/json')
    else:
        objs = Tender.objects.all()[:4]
        print serializers.serialize('json', objs)
        return HttpResponse(serializers.serialize('json', objs), content_type='application/json')
else:
    print 'here'
    raise Http404

Ajax :

 $.ajax({type:"POST",url: "GetTenders",dataType: "json",
                            data: { "Page": $(this).text() },content_type:'application/json',
                            success:function (data) {
                            for(x in data){
                                alert(x.model);}}})

调试(浏览器响应):

[{"model": "Register.tender", "pk": 1, "fields": {"Name": "First", "Kind": "Public Trend", "Category": 1, "Description": "my first bid ", "Created_on": null, "Modified": null, "Active": true, "Size": "S", "Ministry": 1}}]

警告信息:

任何想法:D

Answer 1

循环中的

x 是数组的索引，因此您需要:alert(data[x].model)

参见 for..in loop

此外，如果您使用的是 Django 1.7+，请使用 JsonResponse

from django.http import JsonResponse

    ...

    else:
        objs = Tender.objects.all()[:4]
        return JsonResponse(objs)
