jQuery.validity
jQuery.validity (MIT) by Wyatt Allen is a simple form validation plugin:
$('form').validity(function() {
$('#vehicles')
.require()
.match('number')
.range(4, 12);
$('#dob')
.require()
.match('date')
.lessThanOrEqualTo(new Date());
});
The available validators are:
- Require (make sure a value is present)
- Match integer, date, email, usd, url, number, phone, guid, time12, time24, regex
- Range
- Boolean operators (greater/less than, etc.)
- Length
- Non-HTML
- Aggregate equal (check each matched element equals each other)
- Uniqueness
- Sum
- Customised validation with
assert
