[Solved] unlock fields based on combined box value

[peppe10]

Hello to all,
in one form I have a combo box and other fields like in the link http://www.segi.altervista.org/index.php/esempio1

I wish I could get the following result based on the selection in the combo box.

if I select A fields 2 and field 3 remain blocked
If I select B the fields 2 and 3 are unlocked and are writable.

Thank you all

Have you tried using the "readonly and "not readonly" actions on Javascript events on the 'titolo' element?

Hello
I tried but I can not.
in practice I left fields 2 and 3 read-only.
On the 'titolo' element, on Javascript actions how should I set the code?
thanks

You'll need four JS events

if this element = A readonly camp02
if this element = A readonly campo3
if this element = B not readonly campo2
if this element = B not readonly campo3

-- hugh

I entered, but it does not seem to work.
if this element = A readonly a_tabella1___campo2
if this element = A readonly a_tabella1___campo3
if this element = B not readonly a_tabella1___campo2
if this element = B not readonly a_tabella1___campo3
do you need some brackets?

No, I didn't mean use that as literal code. Set up your individual JS events so they match that description.

So the first event:

Event: change (or click)
If this element: ==
Value: A
Action: readonly
Element: campo2

... then add three more for each other action.

I set read-only fields 2 and 3
If I click A, read-only fields 2 and 3 remain.
If I click B the fields 2 and 3 become fillable.
If I then re-insert A, fields 2 and 3 should return to read only, but this does not happen.
What is missing?

could there be a solution?
thanks

It looks like you only added the two events to set "not readonly" if the value is B. You haven't added the two events to set them "readonly" if the value is A.
