[jQuery] Re: Validation with rewriting

Having JS sanitize for the backend is somewhat dubious, I'd not go
there, but you probably don't want to discuss that.

Anyway, a validation method has access to the validate element, so you
could as well write a method that just sanitizes, nothing else.
Combine that with a strict validation method, ala:

rules: {
ssnfield: {
required: true
ssncleaner: true,
ssn: ssn
}
}

No change to required needed. ssncleaner would always return true, and
change the input value; ssn would just validate a strict ssn.

A very simple and general sanitizer would just trim whitespace - the
plugin did that in earlier versions, but that wasn't desired in
general:

$.validator.addMethod("trim", function(value, element) {
element.value = $.trim(value);
return true;
});

That seems to be quite flexible to me.
