I don't get it. That would require sending the data to the server (right?), so it's not really client-side. I think http://www.dajaxproject.com/ does exactly that. What I would like to see instead is providing HTML5 attributes for standard fields and making it easier to add ones to custom ones. Some simple to implement ones are: "required", min/max for number fields, max_length for a textarea. Regular expression can be supported via "pattern" (with some code to translate them to JS regexp syntax). -- Łukasz Rekucki -- You received this message because you are subscribed to the Google Groups "Django developers" group.
