I was researching an article for PortaBlogger and came across this web form validation/confirmation mechanism on the Opera Community site:
As the form fields are filled in, the green check icon appears for a valid entry - in real time. Here’s an example - I entered the first four letters (Andr) of my desired username (AndrewBoyd), and saw this:
Isn’t that cool? I don’t have to fill out the whole form then wait for 30 seconds while it decides whether my state should be Alabama or ACT before it tells me that I need to choose another user ID. Not only that, it suggests alternates on the fly without getting in the way.
I’m working on a project with Matthew Hodgson at the moment where we’re having to look at intelligent data entry validation mechanisms, so this is very timely.
I can’t fault it - if you would, go to the Opera Community site and have a play with it - if you can find a hole in this as the friendliest form validation ever, please let me know.
