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

[Richard Davies]

Hi again,

I'm unaware of any hooks to do that specifically. I know there are hooks
for before and after saving a record, but IIRC you cannot access the TCA.
There are two files you may find useful hooks in:
1. t3lib_tcemain -> does the saving/loading of TCA form records
2. t3lib_tceforms -> seems to render the TCA forms
