Witam, mam problem. Chciałem stworzyć klienta z wykorzystaniem ajax, ktory pobierze liste studentów oraz doda nowego studenta. Działa mi aktualnie tylko pobieranie listy, natomiast dodanie nowego juz nie. Siedze juz kilka godzin i niewiem czy błąd jest w kodzie czy w może ustawieniach. Proszę o wskazówki i z góry dziękuję za odpowiedź.
Widok:
@{
ViewBag.Title = "Students API";
}
<br />
@using (Html.BeginForm())
{
<br /><button id="GetStudents">Get Students</button> <br />
<br /><button id="btnAddStudent">Add Student</button> <br />
<div id="Emessage"></div>
}
@section Scripts {
<script type="text/javascript">
$(function () {
$('#GetStudents').on("click", function () {
$.ajax({
type: "GET",
url: '/api/API',
datatype: 'json',
cache: false,
})
.success(function (data) {
var info = "";
for (var i = 0; i < data.length; i++) {
info += "<hr />";
info += "<b>Student ID : </b>" + data[i].Id + "<br />";
info += "<b>Name : </b>" + data[i].Name + "<br />";

}
$('#Emessage').html(info);
})
.error(function (xhr, ajaxOptions, thrownError) {
$('#Emessage').html("Error : An error occured");
});
return false;
});
$('#AddStudent').on("click", function () {
var Students = {Name: 'Arnold', Surname: 'Schwarzenegger' };
$.ajax({

var info1 = "<hr /><b>The new student is the following</b><br />";
