[web2py] Using jquery to put default value in a field

[Johann Spies]

Using the following model:

db.define_table('akb_authors',
                                     Field('surname'),
                                     Field('firstname'),
                                     Field('name'),
                                     )
        self.db.akb_authors.surname.widget = suggest_widget(self.db.
akb_authors.surname,
                                                            limitby = (0, 20
), min_length = 2)
        self.db.akb_authors.firstname.widget = suggest_widget(self.db.
akb_authors.firstname,
                                                            limitby = (0, 20
), min_length = 2)


Using SQLFORM.factory which includes other fields not shown here I want to 
the 'name' field to have a default value formed by the first two fields 
like this:  'surname' + ' , ' + 'firstname' 

I have tried with the following code and it is doing nothing for what I can 
see and I am too much of a beginner with jquery/javascript to know how to 
debug it using Firebug:

<script>
$(document).ready(function() {
$('form:input[name = "surname"]').change(function() {
    var van = $('#no_table_surname').val();
    var fn = $('#no_table_firstname').val();
    $('#no_table_name').val(van + ' , ' + fn);
});
$('form:input[name = "firstname"]').change(function() {
    var van = $('#no_table_surname').val();
    var fn = $('#no_table_firstname').val();
    $('#no_table_name').val(van + ' , ' + fn);
});
</script>
   

What am I doing wrong?

Regards
Johann
