Pager

The variants are needed to map two different usages of the pageNum parameter.

  • default – pageNum is added as GET query parameter (e.g. for search results page)
  • page-as-url – pageNum is added somewhere in the URL, according the replacement-pattern in in FORM[data-page-url-template] (e.g. expert forums)

The trigger for the different handling is in the JS and looks for specific elements in the markup:

  • default – when there is an INPUT[type="hidden"][name="pageNum"] element
  • page-as-url – when there is an FORM[data-page-url-template] element

Apart from that: anything put as INPUT[type="hidden"] elements in the code will be submitted as GET query parameter.
