Thanks to all!
The necessary code to solve it, is:
on Tg 0.9a9
=== in kid template ===
...
<head>
<script type="text/javascript" rc="/static/javascript/test.js"></script>
</head>
<body onload="ajax_setup()">
${form.display(form_data)}
</body>
=== test.js ===
function ajax_setup(){
connect(document.modificar.field1, 'onchange', sumfields);
connect(document.modificar.field2, 'onchange', sumfields);
}
function sumfields(){
var myform = document.modificar;
var field1val = parseInt(myform.modificar_field1.value) || 0;
var field2val = parseInt(myform.modificar_field2.value) || 0;
myform.suma.value = field1val + field2val;
}
=== in app.cfg ===
...
# List of Widgets to include on every page.
tg.include_widgets = ['turbogears.mochikit']
=== in controllers.py ===
...
class MyCampos(W.WidgetsList):
id = W.HiddenField(validator=v.Int)
field1 = W.TextField(label="fiedl1",validator=v.Int)
field2 = W.TextField(label="field2",validator=v.Int)
suma = W.TextField(label="Suma",validator=v.Int)
class MyForm(W.ListForm):
fields = MyCampos()
name="modificar"
template = "tgtest.templates.editform"
