: '''''This script is operational: its main features work; it is under further development'''''
ViewAnnotationToggler.js: adds a tab menu item and hot key to turn list item annotations off and on, across all pages..
The hot key is {{keypress|Shift|Alt|a}}.
This script works on the list items in bulleted lists, lists in which each item is
preceded by a bullet. Bulleted lists abound upon Wikipedia. They are used in stand-alone
lists which are entire articles that are lists, and they are used in embedded lists
situated within articles.
Many list items have an annotation, that is, the list item is followed by a description.
These descriptions are useful, but they may obscure the items in the list that they
describe. Sometimes, it is useful to look at the bare list, without the annotations.
This script turns those descriptions on and off. It provides a tab menu command and
a hotkey for doing so.
When you don't need to see the descriptions, turn them off. When you need more detail,
hit the toggle again, and the descriptions return. The script stores its status so it
doesn't start over between pages — when annotations are turned off, they are off for
all pages until you turn them back on again.

=== The ready() event listener/handler ===
Line 69 ⟶ 87:
The ready() event listener/handler makes the rest of the script wait until the page (and its [[Document Object Model|DOM]]) is loaded and ready to be worked on. If the script tries to do its thing before the page is loaded, there won't be anywhere for it to place the menu item (mw.util.addPortletLink), and the script will fail.
The part of the script that is being made to wait goes inside the curly brackets.
<syntaxhighlight lang="javascript">
1 $(function() {<br>
2 // Body of function (or even the rest of the script) goes here, such as a click handler.<br>
3 });

First, it checks if the Vector skin is being used and runs the rest of the script only if it is.
Then it checks the status of the script, that is, whether it was set to "show" or "hide" the last time it was used.
Then it calls the function that corresponds with the current status (calling either annoHide or annoShow, defaulting to annoShow if there is no status).

==== localStorage.setItem ====
The [https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage <code>localStorage</code> property] allows you to store some data in the browser's memory area for later use, so you don't lose it when changing pages or closing the browser.
What we use it for in the script is to store the script's show/hide status, so we can check it (each time the script starts) to see whether the script is supposed to execute the annoHide or the annoShow function. To create a data item in localStorage named "annostatus" for storing the value "show", we do this:

It has up to 7 parameters, with the first 3 being required. Only those 3 are used above.
'''Important:''' It won't do anything until you bind it to a click handler (see below).
General usage:
<syntaxhighlight lang="javascript">
mw.util.addPortletLink( 'portletId', 'href', 'text', 'id', 'tooltip', 'accesskey', 'nextnode');
</syntaxhighlight>
It's components:
* <code>mw.util.addPortletLink</code>: the ResourceLoader module to add links to the portlets.
* <code>portletId</code>: portlet id— the section where the new menu item is to be placed. Valid values:
** <code>p-navigation</code>: Navigation section in left sidebar
** <code>p-interaction</code>: Interaction section in left sidebar
** <code>p-tb</code>: Toolbox section in left sidebar
** <code>coll-print_export</code>: Print/export section in left sidebar
** <code>p-personal</code> Personal toolbar at the top of the page
** <code>p-views</code> Upper right tabs in Vector only (read, edit, history, watch, etc.)
** <code>p-cactions</code> Drop-down menu containing move, etc. (in Vector); subject/talk links and action links in other skins
* <code>href</code>: Link to the Wikipedia or external page
* <code>text</code>: Text that displays
* <code>id</code>: HTML id (optional)
* <code>tooltip</code>: Tooltip to display on mouseover (optional)
* <code>accesskey</code>: Shortcut key press (optional)
* <code>nextnode</code>: Existing portlet link to place the new portlet link before (optional)
The optional fields must be included in the above order. To skip a field without changing it, use the value <var>null</var>.

Improvements needed:
* Don't run on move pages
* Since it hides content, an indicator is needed to show when it is on/off.
* Fix the conflict with sidebar toggle (it also uses hot-key Shift-Alt-a)

== Development notes ==
=== Trycatch needed, and more ===
:The Transhumanist, where you use local storage.getItem() or setItem() you should always wrap that in try catch, as it can fail at any moment (even if you checked previously). This can be due to the browser running out of storage space for the ___domain, or because the browser is running in privacy mode or with an ad blocker extensions or something. Also, your new RegExp() calls should be lifted outside of the for loops, so that they aren't continuously recreated. For wpTextbox1.value, realise that sometimes the content might be managed by an editor (The syntaxhighlighting beta does this for instance). We use the [https://phabricator.wikimedia.org/source/mediawiki/browse/master/resources/src/jquery/jquery.textSelection.js jquery.textSelection plugin] to abstract way from these differences. Don't check document.title, check mw.config.get( 'wgTitle' ) or mw.config.get( 'wgPageName' ). And when you use mw.util.addPortlink, you have to ensure that the mediawiki.util plugin is loaded already, which you can do by using [https://doc.wikimedia.org/mediawiki-core/master/js/#!/api/mw.loader mw.loader.using]. —[[User:TheDJ|Th<span style="color: green">e</span>DJ]] ([[User talk:TheDJ|talk]] • [[Special:Contributions/TheDJ|contribs]]) 14:47, 27 October 2017 (UTC)

== The Bug Report ==
Hi, {{ping|The Transhumanist}}. I've discovered an unintended side-effect caused by a line of code in your script, or should I say ''the'' line of code.
<syntaxhighlight lang="JavaScript>
cont.outerHTML = cont.outerHTML.replace(/(<li>.*?)( –.*)/g,'$1<span class="anno">$2</span>');
</syntaxhighlight>
This code strips action handlers from DOM elements which are descendants of <code>mw-content-text</code>. This notably affects 'buttons', such as the 'show/hide' button in the following templates:
{{collapse top}}
Peekaboo.
{{collapse bottom}}
{{Fragaria|state=expanded}}
You ''might'' be able to prevent this by iterating through <code><li></code> elements, like so:
<syntaxhighlight lang="JavaScript">
$("#mw-content-text li").each(function()
{
$(this).html($(this).html().replace(/(.*?)( –.*)/g,'$1<span class="anno">$2</span>'));
});
</syntaxhighlight>
Let me know if this helps! Regards, <span style="font-family:Times New Roman">[[User:Guywan|''GUYWAN'']] ( [[User talk:Guywan|''t'']] · [[Special:Contributions/Guywan|''c'']] )</span> 12:20, 6 June 2019 (UTC)
