html超链接为变量,如何向超链接添加变量值

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 %}

Subjects

Enter subject name to add

{% csrf_token %}

{{ subject_creation_form.as_p }}

myID

{% 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 –
