message shows undefined when ajax post in ASP.net – Jquery ajax

Hi I’m Fairly new at coding and in asp.net and had an error occurred to me please help me if you can. This is my script when I run the code given below using an onclick function the success message shows as undefined and c# function SaveData which I placed in break point doesn’t hit. clearly the post didnt reach the server function.

text1 and text2 are two variables

$.ajax({
    type: "post",
    contentType: "application/json; charset=utf-8",
    url: "Default.aspx/SaveData",
    data: "{dataval: '" + text1 + "', dataval1: '" + text2 + "'}",
    dataType: "json",
    success: function (data) {
        alert(data.d);
    },
});

server side

[WebMethod]
public static string SaveData(string dataval, string dataval1)
{
    string data = String.Format("Your Name is {0} and address is {1}", dataval, dataval1);
    return data;
}

    Ok I have found the answer to my problem. The problem was with commenting a piece of code in RouteConfig.cs file in App_Start folder.

     //settings.AutoRedirectMode = RedirectMode.Permanent;

    Don't know why but it worked fine after this. Please let me know how this works.

    $.ajax({
        type: "GET",
        url: "/Home/SaveData",
        data: { dataval: 'asd', dataval1: 'asd' },
        dataType: "json",
        success: function (data) {
            debugger
            alert(data);
        },
        });
    });

    Backend

    [HttpGet]
    public ActionResult SaveData(string dataval, string dataval1)
    {
        string data = String.Format("Your Name is {0} and address is {1}", dataval, dataval1);
        return Json(data, JsonRequestBehavior.AllowGet);
    }
