The JSBreadCrumbs extension is a simple extension that adds a jQuery-based JavaScript file and a CSS file to your wiki's output that will add a trail of navigation bread crumbs below the navigation tabs. The idea is for a simpler history than your back button that only tracks navigation inside of the wiki. Unlike the browser's back button, it will only track GET requests, not POSTs, and will remove duplicate entries from the list.

Supports multiple MediaWiki skins including Vector, MonoBook, Foreground and Chameleon. Except for Vector vertical bread crumbs are not supported.

This extension creates breadcrumbs in the traditional "How did I get here?" sense; use Extension:BreadCrumbs2 for breadcrumbs in the category-based "Where am I?" sense.

Installation

• Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens JSBreadCrumbs im Ordner extensions/ ablegen.
  Entwickler und Code-Beitragende sollten stattdessen die Erweiterung von Git installieren, mit:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/JSBreadCrumbs
• Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen:

  wfLoadExtension( 'JSBreadCrumbs' );
  

• Configure as required.
•  Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.

Konfiguration

Konfigurationsparameter

There are four configuration parameters that may be specified in "LocalSettings.php":

Configuration Flag	Default Value	Description
$wgJSBreadCrumbsHorizontalSeparator	""	The separator used between bread crumbs when used in horizontal mode. If left blank (the default value), the value of the jsbreadcrumbs-horizontal-separator message will be used.
$wgJSBreadCrumbsCSSSelectorHorizontal	[]	An array of mappings from skin to the CSS selector that should be used to anchor the bread crumb trail when displaying bread crumbs in horizontal mode while using that skin. There is a default mapping of skin to CSS selector for horizontal mode that is used if no value exists for a skin in this array.
$wgJSBreadCrumbsCSSSelectorVertical	[]	An array of mappings from skin to the CSS selector that should be used to anchor the bread crumb trail when displaying bread crumbs in vertical mode while using that skin. There is a default mapping of skin to CSS selector for vertical mode that is used if no value exists for a skin in this array.
$wgJSBreadCrumbsGlobalMaxCrumbs	20	The maximum number of bread crumbs that will be saved in the cookie for a domain. If multiple wikis exist on the same domain, this value will limit the total number of bread crumbs summed across all of those wikis. This can help to prevent the cookie value from becoming too large and causing a browser error.

Benutzereinstellungsoptionen =

In addition, there are 8 user preference options. These have default values that can be overridden in LocalSettings.php (see below). Users can then override those default values by visiting Special:Preferences and editing them on the Appearance tab. The user preference options are:

User Preference Option	Default Value	Description
jsbreadcrumbs-showcrumbs	true	Controls whether a bread crumb trail will be displayed.
jsbreadcrumbs-numberofcrumbs	5	The maximum number of crumbs displayed in the bread crumb trail.
jsbreadcrumbs-horizontal	true	If true, the bread crumb trail will be a horizontal list. If value, it will be a horizontal list.
jsbreadcrumbs-maxlength-horizontal	40	The maximum length of the link text for a bread crumb (not including the optional action or site name) when in horizontal mode.
jsbreadcrumbs-maxlength-vertical	20	The maximum length of the link text for a bread crumb (not including the optional action or site name) when in vertical mode.
jsbreadcrumbs-showaction	false	If false, page links with actions associated them (e.g. ?action=historyor ?action=edit) will not generate separate bread crumbs. Instead, a link to the page without the associated action will be used. If true, each action will create its own bread crumb, and the action will be shown after the page name. If there is a localized message string for the action, that will be used.
jsbreadcrumbs-showsite	false	If true, the name of the wiki will be shown before the page name. This is useful in wiki farms if the user wants to distinguish between links to different wikis on the same domain.
jsbreadcrumbs-domain	false	If true, the bread crumb trail may include bread crumbs from any wiki on the same domain as the wiki for the currently displayed page. If false, only bread crumbs from the current wiki will be displayed.

To override the default value of a user preference option, you can put code similar to the code below in your "LocalSettings.php". That is, with this code in "LocalSettings.php", the value of jsbreadcrumbs-maxlength-horizontal used for a user if they do not edit the value in Special:Preferences will be 50 rather than the default value of 40 provided in "extension.json".

$wgDefaultUserOptions['jsbreadcrumbs-maxlength-horizontal'] = 50;

Cookies

This extension uses a cookie, mwext-jsbreadcrumbs, to store the breadcrumb trail for a period of 30 days.
