【问题描述】:
这是我的 ajax 函数:
$('a.username').on('click', function() {
var username = $(this).html();
var url = window.location.href.split('?')[0];
$.ajax({
type: 'GET',
url: url,
data: {
username_clicked: username,
csrfmiddlewaretoken: $("input[name='csrfmiddlewaretoken']").val()
},
success: function (data) {
console.log(data.username_clicked)
}
})
});
和模板:
<h3><a href="{% url 'raise_profile' %}" class="username">{{ i.author }}</a></h3>
网址
url(r'^raise_profile/', raise_profile, name='raise_profile'),
并查看:
def raise_profile(request):
if request.method == 'GET':
print('get') #prints 'get'
username_clicked = request.GET.get('username_clicked')
print(username_clicked) #prints 'None'
return render(request, 'article.html', {})
console.log(data.username_clicked) 不记录任何内容。但是如果我去掉模板中的{% url 'raise_profile' %},那么它会记录正确的数据。问题是什么原因?
编辑:
查看:
def article(request, category, id):
name = resolve(request.path).kwargs['category']
for a, b in CATEGORY_CHOICES:
if b == name:
name = a
instance = get_object_or_404(Post, id=id, category=name)
allauth_login = LoginForm(request.POST or None)
allauth_signup = SignupForm(request.POST or None)
#comments
comment = CommentForm(request.POST or None)
ajax_comment = request.POST.get('text')
comment_length = len(str(ajax_comment))
comment_list = Comment.objects.filter(destination=id)
score = CommentScore.objects.filter(comment=comment_list)
if request.is_ajax():
if comment.is_valid():
comment = Comment.objects.create(comment_text=ajax_comment, author=str(request.user), destination=id)
comment.save()
score = CommentScore.objects.create(comment=comment)
score.save()
username = str(request.user)
return JsonResponse({'text': ajax_comment, 'text_length': comment_length, 'username': username})
else:
print(comment.errors)
context = {
'score': score,
'comment_list': comment_list,
'comment': comment,
'instance': instance,
'allauth_login': allauth_login,
'allauth_signup': allauth_signup
}
return render(request, 'article.html', context)
def raise_profile(request):
username_clicked = request.GET.get('username_clicked')
print(username_clicked)
if request.is_ajax():
profile = Profile.objects.get(username=username_clicked)
print('Age:', profile.age)
return HttpResponse()
网址:
url(r'^(?P<category>\w+)/(?P<id>\d+)/', article, name='article'), #original view
url(r'^raise_profile/', raise_profile, name='raise_profile'),
Edit2:要将数据发送回模板,我尝试了这些:
def raise_profile(request):
username_clicked = request.GET.get('username_clicked')
if request.is_ajax():
profile = Profile.objects.get(username=username_clicked)
print('Age:', profile.age)
profileAge = profile.age
response_data = json.dumps({'profile_age': profileAge})
return HttpResponse(response_data, content_type='application/json')
和
def raise_profile(request):
username_clicked = request.GET.get('username_clicked')
if request.is_ajax():
profile = Profile.objects.get(username=username_clicked)
print('Age:', profile.age)
profileAge = profile.age
return JsonResponse('profileAge': profileAge)
base.html
<p class="profile_age">{{ profileAge }}</p>
然后什么都没有出现。但是当我在视图中打印 profileAge 时,它会返回 4。知道为什么数据没有发送到我的模板吗?
【问题讨论】:
-
你在 ajax 调用中得到“用户名”吗?请先检查“用户名”变量控制台。记录或提醒它,然后检查你得到了什么。
-
刚刚在
var username = $(this).html();下添加了console.log(username),是的,它记录了正确的数据(用户名)。
