This post collects all my notes and references on j Query Form validation library.This includes a large bunch of sample code and a complete reference guide to all the built-in validation rules in the library.The beauty of these elements is that you can use them now: for browsers that don't support a particular input type, there is automatic fallback to standard textfields.There are two keys to understanding why the automatic fallback works consistently in all major browsers: (unless "foo" is a recognized input type or "bar" is a recognized attribute of the input element).Firefox and Safari had moderate support, and Internet Explorer had no support at all.For each type of input element, we use the code to detect if your browser supports it. You should normally supply all of value, min, and max.
HTML5 defines a variety of new input types: sliders, number spinners, popup calendars, color choosers, autocompleting suggest boxes, and more.
If you imagine form as a dialog between your website and your user, the messages play an important role.
Don’t leave it to the auto-generated default messages.
Though for the datetime and date validator to you need to specify a parse and format function and for that you most likely will want to use a library, is highly recommended.
If you want to use async validation you need to use a runtime that supports Promises.
