# Breaking: #91578 - IRRE related JavaScript has been removed {#breaking-91578}

See [forge#91578](https://forge.typo3.org/issues/91578)

## Description {#description}

The JavaScript functions `TBE_EDITOR.fieldChanged_fName` and its legacy
alias `TBE_EDITOR_fieldChanged_fName`, used to extract the table name, field
name and uid from the incoming field name, have been removed.

## Impact {#impact}

Calling any of the removed function will trigger a JavaScript error.

## Affected Installations {#affected-installations}

All 3rd party extensions calling these functions are affected.

## Migration {#migration}

No migration is possible as this is IRRE-related code only.
