Re: Form validation on blur or on form submission

You always have to do error checking on submit. That's the safe base level.
Question is, do you want to go above and beyond that.
I think that question starts with general usability testing to see
what, or a lack of a better word "regular usres" prefer.
If they prefer oninput/onblur validation they should have it.
The second phase I'd carry out the same esting with users of assistive
technologies, who interact differently with the page and decide
whether to make the more aggressive error validation available to them
by use of live regions.
