删除记录的确认框jquery flexigid c#

我通过从c#controller返回json格式的记录来填充jquery flexigrid。然而，我面临着一点小问题。我正在添加herf列以删除特定记录。它的作品很好，但我无法找到方法，以确认它删除之前。下面是我的c代码，它将记录返回到flexigrid

C#控制器代码段

    private JsonResult CreateFlexiJson(IEnumerable<user> items, int page, int total)
    {
        var CurentsessionUser = Session["sessionUserId"].ToString();

        List<Object> rows = new List<Object>();
        foreach (var item in items)
        {
            rows.Add(new
            {
                id = item.id,
                cell = new string[] {                   
                item.msisdn,
                item.pin,
                item.subtype,
                CurentsessionUser =="csagent"?"":String.Format("<a href=" + "'" + "ChangePin?subno=" + item.msisdn + "'" + ">Change Pin</a>"),
                CurentsessionUser =="csagent"?"":String.Format("<a href=" + "'" + "Delete?subno=" + item.msisdn + "'" + ">Delete</a>")              
            }
            });
        }

        var result = new { page = page, total = total, rows = rows };

        return Json(result);

    }

    public ActionResult Delete(string subno)
    {
        try
        {
            wmas_subsEntities entitymodel = new wmas_subsEntities();

            var customer = from p in entitymodel.users where p.msisdn == subno select p;

            if (customer.ToList().Count > 0)
            {
                entitymodel.users.Remove(customer.First());
                entitymodel.SaveChanges();                    
            }

            //return Json("Successfully deleted the user registeration");
            return View("Index");
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

在

CreateFlexiJson

操作中，在第行下方进行更改

CurentsessionUser =="csagent"?"":String.Format("<a href=" + "'" + "Delete?subno=" + item.msisdn + "'" + ">Delete</a>")              

CurentsessionUser =="csagent"?"":String.Format("<a href=" + "'" + "Delete?subno=" + item.msisdn + "'" + ">Delete</a>")              

CurentsessionUser =="csagent"?"":String.Format("<a href='javascript:void(0)' onclick='deleteSubscriber(\"" + item.msisdn + "\")'>Delete</a>")      

function deleteSubscriber(subno) {
    if (confirm("Are you sure to delete Subscriber (No. = " + subno + ")")) {
        location.href = "Delete?subno=" + subno;
    }
}
