==Usage==
Simply call this template with {{Usage}} each time the return value should be the opposite of what it was the last time it was called.
This template requires a small workaround to avoid the MediaWiki parser caching the template and not persisting the variable properly. It must be called with an empty argument (or any sort of argument), like so: <code><nowiki>{{Evenodd|}}</nowiki></code> - note the pipe. This is placed wherever an "odd" or "even" value is needed that's the opposite of the previous instance of this template on the same page.


When first called, it returns "odd", unless "even" is passed to the named parameter "init": {{Usage|init{{=}}even}}

odd

Purpose

Each time this template is used within a given page, it toggles the variable "evenodd" between "even" and "odd", returning the resulting value. This can be used to dynamically switch between two different displays, such as rows in a list.

Usage

This template requires a small workaround to avoid the MediaWiki parser caching the template and not persisting the variable properly. It must be called with an empty argument (or any sort of argument), like so: {{Evenodd|}} - note the pipe. This is placed wherever an "odd" or "even" value is needed that's the opposite of the previous instance of this template on the same page.

When first called, it returns "odd", unless "even" is passed to the named parameter "init": {{Evenodd| init=even }}
