这是我的功能： 问题是我不知道如何将“值”添加到“链接”。如何向超链接添加变量值
function add_subject_to_subjects_list() {
var value = $("#id_name").val();
var link = "/subject/create/"+value;
show_subjects_list();
$("#btn-create-subject").click(function() {
$.post(link, function(data) {
show_subjects_list();
alert(data).hide("fast");
});
});
}
因为我的功能POST数据到不同的链接：http://127.0.0.1:8000/subject/create/
但我想我的链接取决于值： ，它应该是这样的：
http://127.0.0.1:8000/subject/create/some_value/
这是整个js为该页面：
$(document).ready(function(){
add_subject_to_subjects_list();
});
function show_subjects_list() {
$.post("/subject/list/", function(data){
for(var i=0; i
$("#list").append('
'+data[i]['fields']['name']+'');
};
}, 'json');
}
function add_subject_to_subjects_list() {
var value = $("#id_name").val();
var link = "/subject/create/"+value;
show_subjects_list();
$("#btn-create-subject").click(function() {
$.post(link, function(data) {
show_subjects_list();
alert(data).hide("fast");
});
});
}
这是我的服务器端(I “M使用Django/Python)的：
@csrf_exempt
def subjects_list(request):
user = request.user
subjects = Subjects.objects.filter(user__exact = user)
result = serializers.serialize("json", subjects, fields=('name'))
return HttpResponse(result)
@csrf_exempt
def new_subject(request, subject):
subject, created= Subjects.objects.get_or_create(
name=subject,
user=request.user,
created_by=request.user)
if created:
message = "Subject was created"
else:
message = "No subject was added to the database"
return HttpResponse(message)
，这就是我的html：
{% block left-menu %}
{% endblock %}
适合该HTML表单：
class SubjectCreationForm(forms.Form):
name = forms.CharField(label="Subject Name", widget=forms.TextInput(attrs={'size':9}))
class Meta:
exclude = ('created_by', 'created_time', 'num_of_followers', 'vote')
def clean_name(self):
name = self.cleaned_data['name']
if len(name)>1:
return name
else:
raise forms.ValidationError("Subject name should be longer")

你可以发布一些更多的代码，特别是在函数被调用和字段$(“＃id_name”) –

它看起来像值是空的，也警告不会返回一个jQuery对象 –
