Updating hidden fields

Updating hidden fields

I have 3 fields on an aspx page:

        <asp:HiddenField ID="hfOne" runat="server" />

        <asp:HiddenField ID="hfTwo" runat="server" />

        <asp:HiddenField ID="hfThree" runat="server" />

I also have a button as follows:

      <asp:Button ID="Process" runat="server" Text="Process" />

I wish to:

Capture the Button Click

Change the hfOne.val based on a function that takes hfTwo.val and hfThree.val.


I have the following, which is incorrect:


    <script type="text/javascript">

        $(document).ready(function () {

            $('#Process').click(function (event) {

                $('#hfOne').val(function (event){return myProcessFunction($('#hfTwo').val,$('#hfThree').val)});

            });

        });

     </script>


I'd be grateful for some help getting the JQuery right.


Thank you
