Bookmarklet to export Leo Trainer words to an Anki deck.

Leo-Anki.js

/**
 * This bookmarklet makes it possible to transfer words from Leo Trainer to Anki.
 * It is configured for fr-de (French to German) translations, but can easily be
 * adapted to other languages.
 * 
 * Prerequisites:
 * - a Leo account (http://www.leo.org/) with a few words saved in the trainer
 * - an Anki account (https://ankiweb.net/account/register)
 * 
 * 1. Crunch the following code and add it to your bookmarks
 *    (see http://ted.mielczarek.org/code/mozilla/bookmarklet.html)
 * 2. Run the bookmarklet
 *    (you might have to run it twice, as the first run will lead you to the correct Leo page)
 * 3. Import the downloaded file in Anki using \t as field separator and allowing HTML in fields

Hi @fbecart it looks there recently was an update to the Leo Trainer site, and the bookmarklet doesn't appear to be working for me anymore. Would you be able to test and let me know if the bookmarklet still works for you?

Thanks so much for all your work on this. I use your bookmarklet so often. It's incredibly helpful!

Hi @paulwiniecki! Indeed, it looks like Leo has updated their page layout. The script made some assumptions which were not valid anymore.

I got the script working again -- by making different assumptions regarding the page layout. Could you please try it out and report any issue?

It's working for me again @fbecart. Thanks for the quick revisions!
