Solution 1

Why not writing just

JavaScript

if (!Sys) {
   // you cannot use Sys
}

Remember that Sys is also an object. In this approach, you make no difference between undefined and null (different objects in JavaScript), but in many cases this difference does not have to be made.

The rest of your post is not quite clear to me, sorry. Your follow-up questions will be welcome.

when and where i'll use ur if condition..
I have below method in javascript

<script type="text/javascript">
$("#ContentPlaceHolder1_ddlCountry").change(function () {
debugger;
var end = this.value;
$('#<%=hdnCountry.ClientID%>').val(end);
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "ProfileEdit.aspx/GetState",
//url: '<%= ResolveUrl("~/ProfileEdit.aspx/GetState") %>',
data: "{'countryID':'" + end + "'}",
dataType: "json",
success: function (data) {
debugger;
$('#<%=ddlState.ClientID%>').empty();
$('#<%=ddlState.ClientID%>').append($("<option></option>").val(0).html('--Select--'));
$.each(data.d, function (key, value) {
$('#<%=ddlState.ClientID%>').append($("<option></option>").val(value.ID).html(value.Name));
});
var items = $("#ContentPlaceHolder1_ddlState option").length;
if (items == 1) {
$('#<%=ddlCity.ClientID%>').empty();
$('#<%=ddlLocality.ClientID%>').empty();
$('#<%=ddlCity.ClientID%>').append($("<option></option>").val(0).html('--Select--'));
$('#<%=ddlLocality.ClientID%>').append($("<option></option>").val(0).html('--Select--'));
}
},

error: function (data) {
alert("Error");
}
});
});
</script>

and below is the code behind method

//[WebMethod]
[System.Web.Services.WebMethod]
public static StateDetails[] GetState(string countryID)
{
List<statedetails> details = new List<statedetails>();
try
{
int cid = Convert.ToInt32(countryID);
HttpResponseMessage response = objCRUD.Get("api/CountryState/0/0/" + cid); // Controller Name
if (response.IsSuccessStatusCode)
{
var Module = response.Content.ReadAsAsync<List<countrystatemodel>>().Result;
if (Module.Count() > 0)
{
DataTable dt = ToDataTable(Module);
foreach (DataRow dtrow in dt.Rows)
{
StateDetails state = new StateDetails();
state.ID = Convert.ToInt32(dtrow["ID"].ToString());
state.Name = dtrow["Name"].ToString();
details.Add(state);
}
}
}
return details.ToArray();
}
catch (Exception ex)
{
throw ex;
}
}
