add data in textbox

Question

 i  have one textbox  and one button

 

<asp:TextBox ID="txtPrevPol" runat="server" Placeholder="Policy No" class="form-control" ValidationGroup="P" />

 

<asp:Button ID="btnPAdd" runat="server" Text="Add" class="form-control btn btn-primary" ValidationGroup="P" />

 

 

i put value first in this textbox (ex: 1234)

 

it added and show in another textbox

 

<asp:TextBox ID="txtPrevPolList" runat="server"  TextMode="MultiLine" ReadOnly="true" ></asp:TextBox>

 

output like that:

 

(ex:

1. 1234)

 

 

again i added the valur in the textbox ( txtPrevPol)( ex :3456)

 

 

show it in the txtPrevPolList

output:

 

(ex:

1. 1234

2. 3456 ) 

 

i am doing this using the following script:

 

<script>

var cnf = $.noConflict();

var count = 1;

cnf('#<%=btnPAdd.ClientID%>').click(function () {
var txt = cnf('#<%=txtPrevPol.ClientID%>').val();
if (txt != '') {
cnf('#<%=txtPrevPolList.ClientID%>').append((count++) + ':' + txt + '\n');
cnf('#<%=txtPrevPol.ClientID%>').val('');
return false;
}

});

 

 

when i fetch  all values from the textbox (

txtPrevPolList

(ex:

1. 1234

2. 3456 ) )

 

  to save it into the database

 

 

 i cannot get the values from the textbox
