Url is undefined in JavaScript

Question

I am developing an application in which I am retrieving data from the database into GirdView. Now when any user clicks on the Get City, it should return the city name of that particular row.

enter image description here

But i am getting the following error:

enter image description here

Following is my script code:

 <script>
    $(document).ready(function () {
        $("a").one("click", function (evt) {
            debugger;
            var stu_id = $(evt.target).closest("tr").children(":first-child").text();
            $.ajax({
                type: "POST",
                url: 'WebForm1.aspx/get_city',
                data: "{'stuid':'" + stu_id +"'}",
                async: false,
                contentType: "application/json; charset=utf-8",
                success: function (final) {
                    debugger;
                    $("#LblCity").append(final.d + "<hr/>");
                },
                error: function () {
                    debugger;
                    alert('error');
                }
            });
        });
    });
</script>

My WebForm1.aspx.cs page code:

[WebMethod]
    public static string Get_City(int stuid)
    {
        MyDatabaseEntities MyDb = new MyDatabaseEntities();

        var data = from db in MyDb.Students
                   where db.ID == stuid
                   select db.City;
        return data.SingleOrDefault().ToString();
    }

What is the error? Your tooltip is showing the jQuery source for $.ajax, not an error message. Have you checked the console? — Rory McCrossan

Have you put breakpoint inside webmethod to see if the code goes there? — kostas ch.

I solved it. I am using Visual Studio 2013 so I just update the RouteConfig.cs file with the following code:

settings.AutoRedirectMode = RedirectMode.Off;

Now everything is running fine. Thanks for helping me.
