On my site (sympathetic-resonances.org), users edit complex forms. Part of the form is musical data passed as JSON in a hidden form field, where a JS frontend reads it from and writes it to. The pages themselves are submitted as regular forms.
I have a few users in countries with very unreliable internet connection. If their form submit fails, edits to the musical data are sometimes lost, depending on the browser. (Firefox offers a Try Again button, Chrome and Safari don't - I wonder why the UX is so bad here in the first place.) Ideally, if users clicked on a submit button and the site can't be reached, the page with the form would remain unchanged (so you might even continue editing), and a dialog would pop up, indicating the problem and asking to try again later. Is there a simple way to achieve this with JS and/or web2py? (I realize that this kind of single-page frontend would better communicate with the backend via AJAX, but there's quite some logic (custom validators etc.) tied to the controller, and unless there's a simple way to keep the controller mainly as-is, I don't want to spend the time for this change right now.) -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
