Feature Request: return validated fields in DOM order

[davidecantini]

Hi @jonjamz ,

I've just noticed that if input fields are re-rendered in a different order with respect to the original one, then the validated data are returned still according to the previous DOM order.
Would it be possible (at least to have an option) to have the fields returned according to the DOM order at the time the action function is invoked? That is the order one would get by simply using jQuery $('.reactive-element').

Thank you for your attention

This is a cool idea. What do you think is the use case for this functionality? I think I would have to flag elements in the DOM by field in order to accomplish this.

This is a real case scenario I'm facing: fields representing tree nodes. If the nodes get rearranged, the DOM gets properly updated according to the new tree structure, but the library fails to provide the proper order.
At this point either the library or the app (using the library) has to do some extra steps.
Do you think it would be possible to add an option in the action function (or wherever it's more appropriate) to enable DOM sorting and letting it disabled if not needed?

Perhaps I didn't fully understand the issue at first glance.

Right now we collect the DOM elements using findAll. This happens at the time the action is run. Are you saying that the solution to this issue is to use a jQuery selector instead? Seems like a simple fix actually.

That should work. According to jQuery specs, elements are returned in document order since version 1.3.2 ( http://blog.jquery.com/2009/02/20/jquery-1-3-2-released/ )
