Passing List String from C# to JavaScript

I am currently trying to check if a value of a string variable is "Apple". Now I need to pass a list of fruits to javascript from C#.
C# Code
List<String> fruits = new List<String>{"Apple","Mango","Orange"}
JavaScript Code
$(document).on('click','#dvAppContent input:checkbox[id*=chkfunction]', function () {
ToggleApplication(this);
});
function ToggleApplication(currentFunction) {
var fruitName = $(currentFunction).closest('ui').parent('label').text().trim();
If(fruitName == "Apple")
{
return true;
}
}

Use Ajax call in JavaScript.
Something like this:
<script>
$(document).ready(function () {
$.ajax({
type: "GET",
url: "/api/StudentAPI/GetAllStudents",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
//alert(JSON.stringify(data));
$("#DIV").html('');
var DIV = '';
$.each(data, function (i, item) {
var rows = "<tr>" +
"<td id='RegdNo'>" + item.regNo + "</td>" +
"<td id='Name'>" + item.name + "</td>" +
"<td id='Address'>" + item.address + "</td>" +
"<td id='PhoneNo'>" + item.phoneNo + "</td>" +
"<td id='AdmissionDate'>" + Date(item.admissionDate,
"dd-MM-yyyy") + "</td>" +
"</tr>";
$('#Table').append(rows);
}); //End of foreach Loop
console.log(data);
}, //End of AJAX Success function
failure: function (data) {
alert(data.responseText);
}, //End of AJAX failure function
error: function (data) {
alert(data.responseText);
} //End of AJAX error function
});
});
</script>
And in the backend in c#, something like this:
public class StudentAPIController : Controller
{
// GET: api/GetAllStudents
[HttpGet]
public IEnumerable<PersonalDetail> GetAllStudents()
{
List<PersonalDetail> students = new List<PersonalDetail>
{
new PersonalDetail{
RegNo = "2017-0001",
Name = "Nishan",
Address = "Kathmandu",
PhoneNo = "9849845061",
AdmissionDate = DateTime.Now
},
new PersonalDetail{
RegNo = "2017-0002",
Name = "Namrata Rai",
Address = "Bhaktapur",
PhoneNo = "9849845062",
AdmissionDate = DateTime.Now
},
};
return students;
}
}

How to submit multiple values using ajax and django

Question I want to be able to submit multiple records with my ajax form submission. This form is a partial and I want to be able to submit multiples of this form each time. This is what I have so far I can't get my textbox.vals anymore using a serialized string. Any help would be greatly appreciated.
Here is my function
function SaveDim() {
$.ajax({
type: "POST",
url: "/sheet/sheet_form_create.html/_dim",
//dataType: "json",
data: $('#form').serialize()
+
"&description=" + $('#id_description').val() +
"&style=" + $('#id_style').val() +
"&target=" + $('#id_target').val() +
"&upper_limit=" + $('#id_upper_limit').val() +
"&lower_limit=" + $('#id_lower_limit').val() +
"&inspection_tool=" + $('#id_inspection_tool').val() +
"&critical=" + $('#id_critical').val() +
"&units=" + $('#id_units').val() +
"&metric=" + $('#id_metric').val() +
"&target_strings=" + $('#id_target_strings').val() +
"&ref_dim_id=" + $('#id_ref_dim_id').val() +
"&nested_number=" + $('#id_nested_number').val() +
"&posistion=" + $('#id_position').val() +
"&met_upper=" + $('#id_met_upper').val() +
"&met_lower=" + $('#id_met_lower').val() +
"&valc=" + $('#id_valc').val() +
"&sheet_id=" + $('#id_sheet_id').val() +
"",
success: function (json) {
console.log(json);
alert(json);
}
});
}
Here is my add_dimension method in views.py
def add_dimensions(request):
if request.method == 'POST':
c_date = datetime.now()
u_date = datetime.now()
description = request.POST.get('description')
style = request.POST.get('style')
target = request.POST.get('target')
upper_limit = request.POST.get('upper_limit')
lower_limit = request.POST.get('lower_limit')
inspection_tool = request.POST.get('inspection_tool')
critical = request.POST.get('critical')
units = request.POST.get('units')
metric = request.POST.get('metric')
target_strings = request.POST.get('target_strings')
ref_dim_id = request.POST.get('ref_dim_id')
nested_number = request.POST.get('nested_number')
met_upper = request.POST.get('met_upper')
met_lower = request.POST.get('met_lower')
valc = request.POST.get('valc')
sheet_id = request.POST.get('sheet_id')
data = {}
dim = Dimension(
description=description,
style=style,
target=target,
upper_limit=upper_limit,
lower_limit=lower_limit,
inspection_tool=inspection_tool,
critical=critical,
units=units,
metric=metric,
target_strings=target_strings,
ref_dim_id=ref_dim_id,
nested_number=nested_number,
met_upper=met_upper,
met_lower=met_lower,
valc=valc,
sheet_id=sheet_id,
created_at=c_date,
updated_at=u_date)
dim.save()
data['description'] = dim.description;
data['style'] = dim.style;
data['target'] = dim.target;
data['upper_limit'] = dim.upper_limit;
data['lower_limit'] = dim.lower_limit;
data['inspection_tool'] = dim.inspection_tool;
data['critical'] = dim.critical;
data['units'] = dim.units;
data['metric'] = dim.metric;
data['target_strings'] = dim.target_strings;
data['ref_dim_id'] = dim.ref_dim_id;
data['nested_number'] = dim.nested_number;
data['met_upper'] = dim.met_upper;
data['met_lower'] = dim.met_lower;
data['valc'] = dim.valc;
data['sheet_id'] = dim.sheet_id;
return HttpResponse(json.dumps(data), content_type="application/json",)
else:
dim_form = DimForm()
return render(request, 'app/_dim.html', {'dim_form': dim_form})

Just do it this way
function SaveDim() {
$.ajax({
type: "POST",
url: "/sheet/sheet_form_create.html/_dim",
//dataType: "json",
//make sure you give your form an id of "dim_form"
data: $('#dim_form').serialize()
success: function (json) {
console.log(json);
alert(json);
}
});
}

You need to concat correctly your data string like:
data: $('#form').serialize() + "&description=" + $('#id_description').val() + "&style=" + $('#id_style').val(); // ...

.empty() function won't work after loading contents with ajax

I did a multilevel ajax call .i.e. make an ajax call and use the id value from the call to make another call... I tried calling a jquery .empty() isn't working for the data generated in the inner ajax call... But when i place the .empty() function on the outer generated element, it worked just fine... How can i fix this issue? This is my code../
$(document).on('click', '.stories', function(e) {
e.preventDefault();
var request = $.ajax({ //first ajax call///
url: 'includes/functions.php?job=front_title',
cache: false,
dataType: 'json',
contentType: 'application/json; charset=utf-8',
type: 'get'
});
request.done(function(output) {
if (output.result === 'success') {
$('.blog').empty();
var jsonArray = $(jQuery.parseJSON(JSON.stringify(output.data))).each(function() {
var id = this.titleID;
var storyTitle = this.story_view;
var frontTitle = '<div class="blog-item"><h3>' + storyTitle + '</h3>' + '<img class="img-responsive img-story" src="images/blog/blog1.jpg" width="100%" alt="" />' + '<div class="blog-content"><div class="entry-meta"><h4>Episodes</h4></div>' + '<div class="well" style="padding-right: 10px; padding-left: 5px; width: 105%;">' + '<ul class="tag-cloud stories">';

var id2 = this.id;
var title = this.title;
var count = this.episode_count;
if (count == 0) {

How to pass values to asp pages from javascript?

I am trying to pass a value from Javascript to ASP pages. But it can't run properly.
This is my Javscript:
function btn_upgrade_onclick() {
var dlr = document.getElementById("<%txt_sapcode.ClientID%>").value;
var dlrname = document.getElementById('<%=tex_dealername.ClientID %>').value;
var addr1 = document.getElementById('<%=txt_addr1.ClientID %>').value;
var addr2 = document.getElementById('<%=txt_addr2.ClientID %>').value;
var addr3 = document.getElementById('<%=txt_addr3.ClientID %>').value;
var mobno = document.getElementById('<%=txt_mob.ClientID %>').value;
var stat = document.getElementById('drp_state').value;
$.ajax({
async: false,
type: "POST",
url: "DealerDetails.aspx/UpdateDealer",
data: "{DlrId:'" + dealerID + "',DlrCode:'" + dlr + "',DlrName:'" + dlrname + "',Dlrad1:'" + addr1 + "',Dlrad2:'" + addr2 + "',Dlrad3:'" + addr3 + "',DlrMob:'" + mobno + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
$("#drp_support").get(0).options.length = 0;
$("#drp_support").get(0).options[0] = new Option("--Select--", "0");
$("#drp_support").unbind("change");
$.each(msg.d, function (index, item) {
$("#drp_support").get(0).options[$("#drp_support").get(0).options.length] = new Option(item.Display, item.Value);
});
$("#drp_support").bind("change", function () {
sprtengId = $(this).val();
});
},
error: function () {
alert("Error");
}
});
}
And the value are passed to the function
region update
[WebMethod]
public static DataSet UpdateDealer(Int32 DlrId,Int32 DlrCode,string DlrName,string Dlrad1,string Dlrad2,string Dlrad3,Int16 Dlrddd,Int32 DlrLan,Int32 DlrMob)
{
DataSet update = new DataSet();
try
{
update=obj.UpdateDealerDetails(DlrId,DlrCode,DlrName,Dlrad1,Dlrad2,Dlrad3,DlrMob);
}
catch {}
return update;
}
#endregion
When I press the Update button, it will call the Javascript function and then it passes the value in the text boxes to the ASP code UpdateDealer();
Before am writing this function in Javascript all other functions worked properly but now it's not working properly

There is a bug in your first line of js.
var dlr = document.getElementById("**<%**txt_sapcode.ClientID%>").value;
Fix this (= missing) and check.
Where have you defined, dealerID
data: "{DlrId:'" + dealerID + "',DlrCode:'" + dlr
also, i dont' think your stat variable is initialized with following line of code just confirm.
var stat = document.getElementById('drp_state').value;
Make sure you debug and variables you have defined are initialized.

remove static from
public DataSet UpdateDealer(Int32 DlrId, Int32 DlrCode, string
DlrName, string Dlrad1, string Dlrad2, string Dlrad3, Int16 Dlrddd,
