MVC Razor View Get Confirm Message Before Delete

I will explain in this post how to get confirm message from user before delete record 

View 

            @Html.ActionLink("Delete", "DeleteEmp", new { id = item.Id }, new { onclick = " return DeleteConfirm()" })

         

Script

 function DeleteConfirm(){

        if (confirm("Are you sure want to delete record"))

            return true;

        else

            return false;     

    }

Controller

   public ActionResult DeleteEmp(int id)

   { 

            var empDelete = (from emp in dbml.M_Employees  where emp.Id == id   select emp).Single(); 

            dbml.M_Employees.DeleteOnSubmit(empDelete); 

            dbml.SubmitChanges(); 

            return RedirectToAction("Index"); 

   }
