Use cursor keys left/right to go through search result pages

[larsen0815]

In #381, you recently added the possibility to go through mails by cursor keys up/down. This PR should do the same for left/right: Go to the previous/next page of search results.

The user could then easily go through all mails and pages just using the cursor keys.

However, this is just a draft. I am not a web dev and ChatGPT wasn't able to create working code to detect the current page.
If you could plese tell me how to solve this, I would update the PR accordingly.

Did it work when you tried it?

[larsen0815]

No, as I said: Just a draft, needs code to get the current page number to then call navigation(). And I don't have the experience how to write that code.

[larsen0815]

So, could you please provide a hint how I can get the current page number?

[jsuto]

templates/common/paging.tpl implements the pagination, it calls navigation() in assets/js/piler.js

[larsen0815]

Yes, but what is the equivalent of $prev_page and $next_page (from paging.tpl) in "piler.js"?
Which variable can be used to get the current page number?

[larsen0815]

Can you help me here? Otherwise I won't get this implemented.

[jsuto]

It's Piler.Shared.page. The navigation() function updates this variable.

[larsen0815]

Thanks, I think I can continue with this in two weeks.

[larsen0815]

Working now. The code handles not going to page 0, but doesn't handle going past the last page as I couldn't find a variable that stores the maximum page number. Doesn't show an error though, so this should be fine.
