Examples/Parameter: scroll (example 2): Difference between revisions

This selects pages from [[:Category:Fruit examples]] and sets display count to the first 3 articles. The <code>scroll</code> parameter enables scrolling and URL variables. The <code>resultsheader</code> argument uses a helper template ([[Template:Extension DPL scroll]]) to create the scrolling navigation. A [[mw:Help:Magic_words#Statistics|magic word]] (<code><nowiki>{{PAGESINCATEGORY:Category}}</nowiki></code>) and some parameters are fed to that template, so it can determine the total number of pages and the amount to show and offset for the navigation display. Setting <code>allowcachedresults=''false''</code> prevents caching, so result changes are immediately seen without the need to manually purge the cache.
