Examples/Parameter: scroll (example 1): Difference between revisions

This selects pages from [[:Category:Fruit examples]]. The <code>{{DPL|count}}</code> displays the first 3 articlesarticle using [[General usage and invocation syntax#Scroll/URL syntax|Scroll/URL syntax]], and an empty <code>{{DPL|offset}}</code> also using that syntax; setting both using scroll/url syntax, allows their query values to be overwritten by URL. The <code>scroll</code> parameter fills the scroll/url parameter values. The <code>resultsheader</code> displays header text to show the count and current result start number. Setting <code>allowcachedresults=''false''</code> prevents caching, so result changes are immediately seen when the URL is changed, without the need to manually purge the MediaWiki cache.

The result is a static display of the first 3 pages, but their display offset (page to start at) and count can be ''overwritten'' just by adding two DPL3-specific URL parameters <code>&DPL_count=31&DPL_offset=31</code> to the end of the ([[mw:Manual:Parameters_to_index.php|index.php]]-style) URL. If you '''copy/paste the URL into your browser's URL bar''', you can see the next 3result results areis loaded from the URL parameters:
