that doesn't work either. Value is still Null
But before we look for the mistake:
is it even possible to access these elements at the end without having declared them explicitly beforehand? Because I have several HTML pages that are dynamically generated by another program. Each element has a unique ID. But I just want to read/describe the elements that are currently present on the called page. So I would also need a way to react to all events of the "unknown" IDs.
