Javascript support

[outsideMyBox]

Hi,

The chapter "Javascript support" states that

Kobo’s Android and iOS platforms support JavaScript for Fixed Layout and reflowable ePubs [...] Kobo’s eInk and Desktop platforms have limited support for JavaScript, and do not support interactive JavaScript elements

and

Note that navigator.epubReadingSystem property is only supported on Kobo's Desktop and eInk platforms and is not presently supported on iOS, Android or Windows.

Why is the navigator.epubReadingSystem not supported for iOS, Android or Windows? It's confusing as later the chapter "support Grid" states that JS is supported for Android and iOS but not for Desktop, eInk, Windows.
Furthermore, according to the EPUB3 spec :

A Reading System that supports scripting must meet the following criteria:
[...] It must implement the JavaScript navigator extension object epubReadingSystem defined in Appendix B, JavaScript epubReadingSystem Object. It also must support the dom-manipulation and layout-change features defined in Features in container-constrained scripting contexts.

@outsideMyBox we have logged this issue and hope to have support added for Android and iOS. If you have a sample file you can pass along we'd be happy to use it to verify the fix once it's been implemented.

Hi,
thanks for looking into this. Unfortunately I don't have a simple example I could share now. I'll test and share an epub once I've got one.

Thanks. Not getting one from you shouldn't hold up our progress but if you can sent one I will attach it to the development request.

Hello,

i complete the thread with an example attached with js generated content, with a localStorage (does not work on eink, have to add a trycatch) supposed to add a number in the h2 tag of the generated content.

activites.kepub.epub.zip
(just remove ".zip" useless extension for github compliance)
