force validate feature, valid if either of two fields is valid

[deltadada]

I have not figured out how to achieve the following:

either fieldA or fieldB needs to be filled to be valid.

if I put a requirement on fieldA and user tabs to it first, the page will show invalid notice before the user gets to fieldB -- unacceptable for client

The validation occurs onblur, before we know where the user is going. If the user clicks in fieldA, leave it blank, and goes to another field besides fieldB, an invalid notice should show to be consistent.

I tried removing the invalid notice for fieldA upon arriving at fieldB, but the error pops up briefly -- unacceptable for client

My thinking now is to do a force validate onfocusout from the enclosing div. I understand how to trigger a submit, but that lists all the errors and brings you to the top of the form.

I just want to force validate fieldA in conjunction with fieldB upon leaving the enclosing div, showing an invalid notice if neither is filled. Is this possible?

Note: if user has info for both fieldA and fieldB, client wants both captured

I think this would be a great feature to have actually. If I have understood you correctly the implementation would look something like this:

<p>
   Phone:
   <input name="a" data-validation="number" data-validation-optional-if-answered="b" />
</p>
<p>
  Cellphone:
  <input name="b" data-validation="number" data-validation-optional-if-answered="a" />
</p>

Scenarios:

• The user leaves a empty and tabs to b and leaves also that input field empty the validation would fire on input b.
• The user starts of in input b and leaves that empty and tabs backwards to a and also leaves that empty the validation would fire on a.
• The user submits the form leaving both empty the validation would fire on b.
• The user leaves a empty and moves to another input that is not the b-input nothing would happen until the entire form gets submitted, alternatively at one point puts focus on b and then goes on leaving the input empty the validation would fire on b.

Would this feature help you with your problem?

Yes, I think you have outlined all the scenarios exactly.

Thanks!
