Hi

I'm fairly new to jQuery and have used Autocomplete against a Zip-code database.
I'm trying a slightly more sophisticated job where I need an additional parameter, an accountID to run with the back end stored procedure. It seems pretty simple, but when I debug my aspx page, the URL parameter accID is coming as undefined.

Any help with where I'm going wrong setting the value of this parameter?

Thanks!! P

JavaScript

<script type="text/javascript">
    $(document).ready(function() {
    var accID = $("#<%=txtHiddenAcctNum.ClientID%>").val();
    $("#<%=txtForwardTo.ClientID%>").autocomplete('AddressBookHandler.ashx?accID=' + accID);
});
</script>

I think you should do something like this.

JavaScript

$("#<%=txtForwardTo.ClientID%>").autocomplete('AddressBookHandler.ashx', {
   extraParams: {
       accID: function() { return $("#<%txtHiddenAcctNum.ClientID%>").val(); }
   }
});

Hopefully that helps or puts you on a path that helps. I got this example from Auto Complete help. If you go there you will be able to find more out about the auto complete function.
