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

This selects pages from [[:Category:Fruit examples]] which has a number of results. The <code>{{DPL|count}}</code> displays the first 3article using articles{{DPL|URL parameters}}, theand an empty <code>{{DPL|offset}}</code> doesn'talso changeusing thethat article count offset because it's set to zerosyntax; setting both using ascroll/url URL variables instead of a numbersyntax, allows their query values to be overwritten by URL. The <code>{{DPL|scroll}}</code> parameter enables scrolling and changes tofills the DPL3scroll/url query (for changing theparameter values for <code>count</code> and <code>offset</code> in order to scroll). The <code>{{DPL|resultsheader}}</code> displays some header text alongto withshow the count and current pageresult start number. Setting <code>{{DPL|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. seenIf below,you causes'''copy/paste the contentsURL ofinto theyour DPL3browser's queryURL on-pagebar''', toyou change;can see the next 3 results in the result setis areloaded displayed. You can copy/pastefrom the following URL into your web browser to see the result change.parameters:
