Notice of change to MediaWiki:Common.js

I have added a snippet to MediaWiki:Common.js that allows users to load a script or stylesheet in the MediaWiki namespace by appending the withJS or withCSS parameter to a URL. See User:JJPMaster/sandbox for an example. JJP_Master (she/they) 10:33, 2 April 2025 (UTC)

Edit requests on MediaWiki:Sp-contributions-footer pages and some message box pages

On MediaWiki:Sp-contributions-footer-anon and MediaWiki:Sp-contributions-footer, please change | type = system to | type = editnotice so that it can adapt to dark mode, thank you.

In addition to the above, we should also modify some of the message box subpages in which they should adapt to dark mode. For instance, the fmbox part when used on MediaWiki:Abusefilter-disallowed does not adapt to dark mode, and makes the currently white text hard to read in dark mode.

@Codename Noreste Just took care of the first part of the request. If you want to workshop specific changes to some of these templates, please feel free! I think an admin/IA can then implement. Cheers —Kittycataclysm (discuss • contribs) 14:32, 26 April 2025 (UTC)

Background color in an unbulleted list.

Hi,

For the first three names in Oberon/hall#Additional_Contributors I've attempted to apply a background color. Can my Wikitext be adjusted to make the background color appear? Thanks, ... PeterEasthope (discuss • contribs) 19:13, 22 April 2025 (UTC)

Done using HTML and CSS rather than MediaWiki. —Justin (koavf)❤T☮C☺M☯ 22:10, 22 April 2025 (UTC)

You have a JavaScript error at MediaWiki:Common.js/Toolbox.js#L-183

Was just passing by, saw an error, wanna report.

Steps to reproduce:

1. Go to https://en.wikibooks.org/w/index.php?title=Template:Book_title&action=edit (Vector 2022 skin)
2. Open JS console
3. Witness an error jQuery.Deferred exception: $.eachAsync is not a function that points to MediaWiki:Common.js/Toolbox.js#L-183.

@Leaderboard @JJPMaster could you investigate? Thank you!! —Kittycataclysm (discuss • contribs) 14:26, 26 April 2025 (UTC)

I'm not that familiar with JavaScript, so will leave this for JJPMaster. Leaderboard (discuss • contribs) 16:07, 26 April 2025 (UTC)

@JWBTH, @Kittycataclysm, @Leaderboard: This should be fixed now. It looks like both this toolbox script and the special characters gadget are attempting to use a nonexistent jQuery method. After some investigation, it looks like they were trying to use a method defined in an unofficial script (this one). I have copied it over to MediaWiki:Common.js/jQueryAsync.js and imported it. JJP_Master (she/they) 17:17, 26 April 2025 (UTC)

Hi @JJPMaster and thank you. Unfortunately, while this error was fixed, a new was introduced: mw.hook(...).add(...) is not a function when editing any page, e.g. [1]. You are trying to pass jQuery, mediaWiki to the return value of

mw.hook('eachAsync.ready').add(function() {
  // ...
})

which is not a function. I suggest to remove (jQuery, mediaWiki) at all since it's not used. JWBTH (discuss • contribs) 05:50, 27 April 2025 (UTC)

Banner not adjusted for dark mode

Another bug report: I was visiting Wikibooks:Community Portal, and in dark mode I saw this:

Oh, look, @Xeverything11 already suggested an edit at MediaWiki talk:Sitenotice#Dark mode support. Their request has not been addressed in 4 months. JWBTH (discuss • contribs) 08:35, 25 April 2025 (UTC)

Help:Contents cut-off on Mobile view on phone

Just a quick note that when viewing Help:Contents on a phone with minerva (the mobile skin), the page is only partially shown; text is cut-off and pinch/zoom doesn't help. Commander Keane (discuss • contribs) 11:28, 26 April 2025 (UTC)

Thanks for the note! Which part is cut off? The right side? —Kittycataclysm (discuss • contribs) 14:25, 26 April 2025 (UTC)
