I hope this community will continue to have patience with all of my newbie inquiries.
So I have this itemId specified, 'startDate':
Visually, the layout, though cosmetically crude/simple, unfolds somewhat according to plan.
In the generated markup, it says the id is "datefield-1015-inputEl". There is no separate itemId.
My actual objective is to programmatically change the state of a field when another field is changed. So, I'm trying to isolate the field. If there's an idiomatic way of doing that that's better than my path, please, point me in the right direction.
Also, the document object is null. So, even if the markup specified the ItemId, I could not use getElementById() to find it since the document is null.
In the meantime, I'll be trying to understand the basic environment I'm working in better.
Thank you, in advance.
Mike
