Validate prefilled jQuery form (invalidate on first field clear, ASP.NET and unobtrustive)
问题 I have a form that can be filled, saved, loaded and re-edited. When it is loaded and re-edited, it probably begins its life valid. When a field is valid upon load, I want it to invalidate immediately when it is edited contrary to rules. That's my question in a nutshell, and I suspect this is supported by some configuration option I can't find. Currently, it works properly (the way desired above) only after: 1) it is edited, 2) then the field loses focus while valid, 3) then is edited it again
