我正在尝试使用 ajax 提交登录表单。我对应该如何处理异常/成功响应感到困惑。我从服务器收到 200 OK 并且表单通过密码/用户名字段返回错误。如何根据服务器响应显示错误消息或将用户重定向到适当的页面?
查询:
56 $(window).load(function(){
57 $('#login_form').submit(function(e){
58 e.preventDefault();
59 var request_url = document.getElementById('next').value
60 $.ajax({
61 type:"POST",
62 url: $(this).attr('action'),
63 data: $('#login_form').serialize(),
64 success: function(response){ $('#msg').text(response);
65 console.log(response);
66 },
67 error: function(xhr, ajaxOptions, thrownError){ alert( $('#login_error').text('Username already taken. Please select another one.')},
68 });
69 });
70 });

51 def login(request):
52 if request.method == 'POST':
53 request.session.set_test_cookie()
54 login_form = AuthenticationForm(request, request.POST)
55 if login_form.is_valid():
56 if request.is_ajax:
57 user = django_login(request, login_form.get_user())
58 if user is not None:
59 return HttpResponseRedirect(request.REQUEST.get('next', '/'))
**else:**
61 **return HttpResponseForbidden() # catch invalid ajax and all non ajax**
60 else:
61 login_form = AuthenticationForm(request)
62
63 c = Context({
64 'next': request.REQUEST.get('next'),
65 'login_form': login_form,
66 'request':request,
67 })
68 return render_to_response('login.html', c, context_instance=RequestContext(request))
形式:
