Simple example program of validating form using onblur function
Similarly we haven't moved over to type=date because we're still using the back-ender's wish of three separate select dropdowns.
Was easier on his end for validation I think, not sure.
But the required setting does or should fire onfocus, since it's hooked up to the CSS :valid/:invalid settings (and I'm not a fan of that: I'm told I'm doing something wrong the moment I'm there, before I've even tried! Also Accessibility Technology are getting told onfocus that the input is invalid. I find it funny that required doesn't work really with pattern. Required seems to only check for empty strings, when you'd think it would check for whatever the input type or other attributes demand... I have to create some ridiculously complicated forms with some optional fields that have to meet certain requirements ONLY if they're filled in, so I will set a pattern that says that there must be pattern, but if it's empty then I don't want it to appear invalid.
This is the behaviour that I am seeing in both FF and Chrome at present.
This tutorial shows you how to set up a basic form validation with j Query, demonstrated by a registration form.
We’re going to use the j Query Validation Plugin to validate our form.
HTML attribute that puts the focus into an element by default when a page loads and other means of getting a focus.
That’s when a user clicks somewhere else or presses to go to the next form field, or there are other means as well.
The browsers are also supposed to be able to choose their own presentation of dates.
While I don't dislike Opera's, I can't imagine everyone wanting a j Query-style date picker for every date.
Or you add titles with your desired error message, which is bad since it still only appears UNDER Opera's version and then you have titles muddying up your inputs and causing havok in screen readers. So Americans whose system claims it's in the US would allow MM-DD-YYYY while most others could get DD-MM-YYYY or whatever.
Or, I remember Bruce Lawson and some others discussing this and supposedly that's how it's supposed to work.
