Hints for javascript in epub ?

[fxp33]

Hi all,

Just checking to see if one of the developers here had any visions of a foreseeable future way to do javascript in epubs on kobo?

What I am looking for:
- tap text or button to change display properties of paragraphs (eg:hiding or displaying translations / versions of text)

Regards

François

Javascript is not supported in ePub 2. There is some support in epub 3. The ACCESS renderer used for kepubs is also used for epub 3. You can have a look at http://epubtest.org/rs/86/ to see how much of the epub 3 function it supports.

Hi DavidFor (and others)

As usual, thank you for the link. Actually, the "form" paragraph gave me some new ideas to try.

To complete the references for people interested in that thread, I have used:

• some test files from the epub3 sample documents
• the recent Kobo Epub support specification
• a list and a sample of mine in .kepub.epub (Kobo WebKit) and .fxl.kepub.epub (Kobo WebKit fixed layout), and normal .epub (Adobe Digital Editions Webkit)

So far my tests for triggering a click event (on span, div, p, and on link) has had no success.

The only way I could mimic a message box was using the old footnote way

Hope it helps, and expecting more options for... 2015

Regards

(The only differences in the hereattached file are the extension and the metadata title, stating the format)

You can do it with CSS only:

Javascript is much useful for web contents, but it is also a wonderful language if you want to get hacked. This is especially true for our rooted devices.

Hi Lucas,

Thank you for your reply and for the nice link.

Unfortunately, the problem is to trigger the clic or tap on the kobo (glo or aura hd).

Maybe I did something wrong (see here attached files), but I couldn't make the example work on my device.

PS: you are absolutely right, I definitely need to update my advanced css tricks

Yep, it seems that input is not supported by epub 2. You could try creating an epub 3. Anyway I tried with this other trick, but it doesn't work.

There's a workaround: for what I remember, footnotes on kepubs are opened in a popup box. I don't know how to generate footnotes for Publus. I suggest you to search between free Kobo books.

Hi Lucas,

Yes, already had a lot of fun with footnotes https://www.mobileread.com/forums/sho...d.php?t=212455

I keep you informed if I find a way to do it.
