Hi!

Thanks for the fast reply.
I would like to extend the functionality of a plugin called Library Tracker
<http://inmysocks.tiddlyspot.com/#My%20Plugins>. so to have an autocomplete
dropdown list on titles with the help of the google books api, similar to
this: https://www.librarieshacked.org/tutorials/autocompletewithapi .
This would be the final goal, now I just would like to transform the
api_url when the input box is edited so that in the next step I could do an
ajax request... but thats not for today, I have no idea how to do that in
TiddlyWikki but with some research and the help of the community, with
small steps I hope to get there soon. :)


Thanks,
Laci
