Finally, I found what was the issue, I have to add "[WebMethod()]" declaration just before the asp.net function. For example,

    [WebMethod()]
    public static string GetData()
    {

        try
        {
            string strjson;
            string connectionstring = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
            SqlConnection Con = new SqlConnection(connectionstring);
            DataSet DS = new DataSet();
            String CmdText = "Select Compname,compadd1,compadd2,compemail from aas_company where compid=@cmpid";
            SqlCommand cmd = new SqlCommand(CmdText, Con);
            cmd.Parameters.Add("@cmpid", SqlDbType.Int).Value = 22;
            Con.Open();
            SqlDataAdapter DA = new SqlDataAdapter(cmd);
            DA.Fill(DS);
            DataTable dTable = DS.Tables[0];
            strjson = GetJSONString(dTable);
            Con.Close();               
            return strjson;
        }
        catch (Exception ex)
        {
            throw new System.Exception("Error In Get Data" + ex.Message);
        }
    }

This answer not for experts only for just beginners, thank you.

dont use alert! That will show this only. Since your response is a Json Object, please try to JSON.stringify it or use console.log to view the data

The reason you are seeing that is that data.d is an object representing the returned JSON text response. When you pass in an object into alert, it displays [object Object]. Whatever you are looking for will be a property of data.d. I would put a breakpoint on that line and see what properties are available. It'll be something like data.d.myProperty which will contain the actual string / HTML you are trying to work with.
