[TYPO3-english] Custom Javascript in View->List forms

[Richard Davies]

Hi again,

There are two things that I know of for conditional display in TCA, but
neither of them involve you adding javascript. If you need the javascript
for alerts etc, you can add a phantom field (e.g. a field called "js" thats
just an int 1 in the database) so you can add a userfunc to the page.

1. If you want to hide a certain field (e.g. if a user chooses 'hide' in
one select box the next select box hides), you can use displayCond[1]
(which isn't what you want)

2. From what I understand you want to hide certain values within a select
box. If the values in select box B (that have some values you want to hide)
are from a foreign table, might be able to use  foreign_table_where mixed
with ###REC_FIELD_[field name]###[1].
For example, set requestUpdate for field A (country), then add a
foreign_table_where clause for field B (state) stating something like
'foreign_table_where' => ' and parentcountry = ###REC_FIELD_country### '
and set
$*TCA*['tablename']['ctrl']['requestUpdate'] = "country"

The above may not be able to do what you want it to do, depending on the
specifics.
