How to add hashtable in jquery

Hi,

I want to add key value pair like hashtable in jquery.

following is my code for adding key value pair to hashtable

$('#btnview').click(function (e) {
e.preventDefault();

var vc = $('#ContentPlaceHolder1_txtvoucherid').val();
var type = $('#ContentPlaceHolder1_txtvtype').val();
var hashtable = {};
hashtable['tablename'] = "vchr";
hashtable['type'] = type;
hashtable['vchrid'] = vc;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "CashPaymentVoucher.aspx/dp",
data: "{'id':'"+hashtable+"'}",
dataType: "json",
success: function (data) {
}
});
});

and following is the webmethod in the next page

[WebMethod]
public static VoucherDetails[] dp(Hashtable id )
{
List<VoucherDetails> details = new List<VoucherDetails>();

BAL obj=new BAL();
DataSet ds = obj.Getsearch(id);
return details.ToArray();
}

i know this is wrong .and showing error .

my requirement is to pass hashtable to another page

like this

DataSet ds = obj.Getsearch(id);

here id is the hashtable from aspx page

error showed was

{"Message":"Cannot convert object of type \u0027System.String\u0027 to type \u0027System.Collections
.Hashtable\u0027","StackTrace":" at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal

Hello Baiju,

Refer the below code :

var ary = [];

function pushToAry(name, val) {
var obj = {};
obj[name] = val;
ary.push(obj);
}

pushToAry("myName", "myVal");
$(your collection of form els).serializeArray();

See the below code is easy :
Hashtable ht = new Hashtable();
ht.Add("1", "abc");
ht.Add("2", "def");
Session["myHashtable"] = ht;
Response.Redirect("Page2.aspx");

on Page2 :
if (Session["myHashtable"] != null)
{
Hashtable ht = (Hashtable)Session["myHashtable"];
foreach (DictionaryEntry dEntry in ht) {
Response.Write(dEntry.Key.ToString() + " " + dEntry.Value.ToString());
}
}

Hope this will help you.
