We wrote a quick Open Whisk serverless action to do the validation.
This j Query plugin makes simple clientside form validation easy, whilst still offering plenty of customization options.
It makes a good choice if you’re building something new from scratch, but also when you’re trying to integrate something into an existing application with lots of existing markup.
Starting with Version 1.15.0 Markus Staab took over the maintenance of the codebase in February 2016.
Since July 2016 Brahim Arkni assisted Markus, and a few months later Brahim joined the j Query Validation core team.
Form validation is natively supported by the browser, but sometimes different browsers will handle things in a manner which makes relying on it a bit tricky. Let’s look at the HTML first: is a temporary URL that would point to something real on a server someplace (where you have backup server-side validation of course).
