Examples/Parameter: scroll (example 1)

Please do not edit this page unless you're wanting to edit the manual itself, it is an example included in the manual.

Example

This selects pages from Category:Fruit examples. The count displays the first 3 articles using Scroll/URL syntax, and an empty offset also using that syntax; setting both using scroll/url syntax, allows their query values to be overwritten by URL. The scroll parameter fills the scroll/url parameter values. The resultsheader displays header text to show the count and current result start number. Setting allowcachedresults=false 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 &DPL_count=3&DPL_offset=3 to the end of the (index.php-style) URL. If you copy/paste the URL into your browser's URL bar, you can see the next 3 results are loaded from the URL parameters:
