Returning error from controller to AJAX jQuery - ajax

Question

I works with ASP.net MVC and I have get "Error" from belowe my JavaScript code:
This is my AJAX jQuery code:
$(document).ready(function () {
var dataId;
$(".item2 .small-img").click(function () {
dataId = $(this).data("id");
var url = '#Url.Action("DecorationTest", "Carpet")' + "?Id=" + dataId + "&title=" + '#Url.ToFriendlyUrl(Model.Title.ToString())';
$('#dateLink').prop('href', url);
$.ajax({
url: '/Carpet/CheckCarpet',
type: 'POST',
dataType: 'Json',
data: '{"CarpetImageid":"' + dataId + '"}',
contentType: 'application/json; charset=utf-8',
success: function (data) {
if (data.Success == false)
$('#dateLink').hide();
else
$('#dateLink').show();
alert("Success");
},
error: function (errorThrown) {
alert("Error");
}
});
and this is a controller code:
[HttpPost]
public ActionResult CheckCarpet(int CarpetImageid)
{
bool DecorShow = false;
DecorShow = db.Images.Where(x => x.Id == CarpetImageid).FirstOrDefault().DecorTest;
return Json(new JsonData { Success= DecorShow });
}
what's the reason? Someone knows?

I found the solution.i change url to #Url.Action("CheckCarpet", "Carpet") and fixed.
$(".small-img").click(function () {
dataId = $(this).data("id");
var url = '#Url.Action("DecorationTest", "Carpet")' + "?Id=" + dataId + "&title=" + '#Url.ToFriendlyUrl(Model.Title.ToString())';
$('#dateLink').attr('href', url);
$.ajax({
url:'#Url.Action("CheckCarpet", "Carpet")',
type: 'Post',
dataType: 'Json',
data: '{"CarpetImageid":"' + dataId + '"}',
contentType: 'application/json; charset=utf-8',
success: function (result) {
if (result.Success == false) {
$('#dateLink').hide();
$('.p2').hide();
}
else {
$('#dateLink').show();
$('.p2').show();
}
},
error: function (error) {
alert(error.d);
}
});
});
