Inline form validation
A List Apart’s article on Inline Validation is one of the most informative I’ve read in a while — and it’s backed by solid data. Some useful lessons: Inline validation can reduce form completion time by 40% Use inline validations where the user doesn’t know if they’ll get it wrong (e.g. is a username available?). Don’t use them if user knows the answer (e.g. their name) Validate on blur, not on keypress (it’s distracting, and users can’t multitask) Comments jesse 25 Sep 2009 4:15 pm: maybe u should add some inline validation on your comments form, instead of the wordpress error page?
