Neither the touch area nor the volume button work, but when I connect a physical keyboard and press PageDown/PageUp/Space key, it working

The weird thing is that it works fine on my phone, but not working on my E-ink device(IReader SmartXs Pro with a 8 inch screen)

plateaukao commented 2 months ago

For first link, it does not work in my iReader Ocean2, but works on my phone. For second link, it works on my iReader Ocean2 and my phone.

For first link, It looks like it shows different layout for tablet and phone size, and that's causing issues which makes EinkBro can't get the correct page height, nor change its page position. I have no way to fix this.

I tried to fix it by find the overflow-y:auto element and scroll on it, work very well for first link. It's a bit of a tricky and not fully tested for other websites.

How about offer an option, force mapping the volume plus/minus key to Physical PageDown/PageUp/Space key?

Or can EinkBro offer a option to limit max screen width? Then the website wiil regard device as phone rather than tablet.

thanks for providing the script. I'll see what I can improve in EinkBro. Also, providing option to map volume key to pageup pagedown is good suggestion, I'll add it to settings.

As for limiting device max width, I'll check whether it's good to provide or not.

The touch area on my boox tab ultra has the same issue with paging on https://feedly.com/i/my as well as the first link. Second link pages as expected.

@xqdd I added the feature in 23c3fc57 You should be able to find "try fix scrolling" when open touchArea Dialog. It will apply the javascript to current website next time you open it. (So, after turned it on, you can reload the page to see if original touch area works.)

@malnoxon it looks like feedly is using other techniques to scroll pages. So the fix does not work.
