Simple example program of validating form using onblur function

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.

First, we need to include j Query v1.x as the validation plugin is currently only compatible with j Query versions lower than 2.0.

There are the following download options: @import "compass"; @import url("https://fonts.googleapis.com/css?

The moment of losing the focus (“blur”) can be even more important.

That’s when a user clicks somewhere else or presses to go to the next form field, or there are other means as well.

As far as I'm concerned, it's a REALLY positive step in the right direction, but it's not perfect yet When the W3C first decided to be a part of HTML5, they did that, yes. They've been diverging ever since though, and the forms section is it seems still being worked on.

Especially the more problematic inputs like colour.

Yeah, imagine your user is Dutch and they think that's 123.456 (one hundred twenty three wholes and four hundred fifty six thousandths). (Over here, 50 euros is displayed as €50,00 or €50,- so the decimal-comma problem is...

What is infuriating however is the way that Chrome/Chromium insists on adding commas to numbers, so my order number 123456 becomes 123,456 to the user.

Not a massive problem because submitting it will submit 123456 but nevertheless, I don't want it to display that way.
