While looking for a solution using Validator, I came across to this link on using Validator.element(). Also interested in the Validator.elements(), so I used the URL https://jqueryvalidation.org/Validator.elements . Invalid page. Poked around the Validator website for document/reference, but neither the document nor reference menu link at top provide any details. Tried Categories at right didn't get it. Is it somewhere or this hard-to-find-things is a natural byproduct of open-source?
It may well be it isn't meant to be a "public" function.
I note that for example, Validator has a .resetinternals() function. It's almost certain it's not meant for you to call it! MOST plugins would have called this _resetInternals() as a clue that you are not to call it.
You can look at the plugin source (which is a lot easier to read!) at GitHub or download it and search with your favorite editor. I easily found the code for .elements(). I don't think it does what you think.
