Bookmarklet to add download links for audiobooks in the Overdrive loans page

bookmarklet.js

/* 1. Paste this entire gist over at https://mrcoles.com/bookmarklet/ to generate a bookmarklet */
/* 2. Use a meaningful Name like: 🎧 📖 Links */
/* 3. Drag the generated bookmarklet link to your Bookmarks Toolbar. */
/* 4. Click on the bookmarklet when you're on the Overdrive loan page, e.g. https://yourlibrary.overdrive.com/account/loans */
/* 5. The "Download MP3 audiobook" link should appear like it used to. */


$('a[data-format-id="audiobook-overdrive"]').each(function() {
    var listenBtn = $(this);
    if (listenBtn.hasClass('script-added')) {
        listenBtn.remove();
        return;
    }
    var dlBtn = listenBtn.clone();
    dlBtn.attr('class', 'loan-button-nonkindle button radius primary downloadButton script-added');
    dlBtn.attr('href', dlBtn.attr('href').replace('/audiobook-overdrive/', '/audiobook-mp3/'));
    dlBtn.html('<b>Download</b><br/><span class="dl-text">MP3 audiobook</span>');
    dlBtn.attr('target', '');
    listenBtn.parent().append(dlBtn);
});

If anybody else is wondering about this, it has to do with OverDrive deprecating the OverDrive app. You now have to use "Libby" - which doesn't even have a Windows application. Anyway, you can still use this scriptlet/bookmarklet to download the ODM file, and then you can use the odmpy commandline tool to open and download it.
The original code base is here: https://github.com/ping/odmpy
but you'll need the forked version here to get past the one-time Setup process: https://github.com/jordkh/odmpy

^ for some reason, the odm download within those projects is not working correctly, but the "DL" option still works with the odm file downloaded with this bookmarklet.
