[Flask] Java script dynamic dropdown

[Mazzei, Stephen Andrew]

Good afternoon,

You all have been incredibly helpful so I am looking for a little more help :) . I am trying to create a dynamic drop down menu based on another dropdown menu. Similar to the <State> <City> type thing.

I have the following

    <script type=text/javascript>
        $('#application').on('change', function() {
            $("#result").empty();
            application_name = $("#application option:selected").text();
            application_id = $("#application option:selected").val();
            $.getJSON('/_parse_models', {
                a: application_name,
                b: application_id
            }, function(data) {
                var options = $("#result");
                $.each(data, function() {
                    options.append($("<option />").val(this).text(this));
                });
            });
            return false;
        });
    </script>

    <div class="container">
        <hr/>
        <div>
        <p>
        <td><select id='application'>
            <option value='1'>1</option>
            <option value='2'>2</option>
            <option value='3'>3</option>
        </select></td>
        <td><select name='result'>
            <option value='{{result}}'>{{result}}</option>
        </select></td>
        </form>
        </div>
    </div>

@mod_validations.route('/_parse_models')
def list_models():
    id = request.args.get('b', 0)
    print id
    return jsonify(result=id)


If I can just receive a little help on getting this part to work, I can figure out how to apply real data. Thank you
