date/dateISO do not check days of month correctly

[jmp909]

as of here: https://jqueryvalidation.org/dateISO-method/

both of these dates don't validate correctly, they should fail

2011-11-31
2011-02-29

normally i would use this which checks the data parsed from the input string matches the supplied date

var d = new Date(Date.parse(str))
return str === (d.getFullYear() + '-' + (d.getMonth()+1) + '-' + d.getDate());

since 2011-02-29 would parse as 2011-03-01, then this would fail properly

please advise

thanks

The date method should not be used since it relays on the Date constructor which behaves differently across browsers. It's stated clearly in the docs of this method.

As for the dateISO method, there is a PR that adds sanity checks (#1528) to the method but not merged yet, as it could be considered a BC break for those who still rely on the old behavior (even though it's wrong).
