I am trying to post the value from view but its not going to action.only null is showing in action

<script>
    $(document).ready(function () {
        
        $("#btn_submit").click(function () {

//这是我的控制器代码

// this is my controller code

public ActionResult Existing_data( tempdata obj) // after debugging only null value showing here
      {
          tbl_country cnt = new tbl_country();

         tbl_state st=new tbl_state();
         if(cnt.cid ==obj.c_id && st.sid==obj.s_id)
         {
             tbl_city tbct = new tbl_city();
             tbct.ctname = obj.ctnam;
             db.tbl_city.Add(tbct);
             db.SaveChanges();
         }


          return RedirectToAction("Country_data");
      }

//这是类

// this is class

public class tempdata
   {
       public int c_id { get; set; }
       public int s_id { get; set; }
       public int ct_id { get; set; }
       public string cnam { get; set; }

var s =

("#s_country").val(); var s =
