How to do pagination when the url does not change

How to?
#1

Hello, I want to pull the descriptions of every page inside this site the problem is the URL does not change between pages. I do know I have to use the element click selector, but my question is how. I do not know what to put on the selector and on the click selector options. I've tried some options but none of them seem to work.

URL =https://www.panamacompra.gob.pa/Inicio/#!/busquedaAvanzada/ListarActosParametros?descripcion=&entidad=%7B%22nom%22:%22Ministerio%20De%20Seguridad%20P%C3%BAblica%20%22,%22id%22:94534,%22rut%22:%223-NT-333-3333%22%7D&estado=0&fd=2019-07-01T19:50:47.521Z&fh=2020-02-12T19:50:47.526Z&provincia=0&tcompra=-1&ucompra=%7B%22disabled%22:true%7D

My sitemap is: {"_id":"ministerio_de_seguridad","startUrl":["https://www.panamacompra.gob.pa/Inicio/#!/busquedaAvanzada/ListarActosParametros?descripcion=&entidad={"nom":"Ministerio%20De%20Seguridad%20Pública%20","id":94534,"rut":"3-NT-333-3333"}&estado=0&fd=2019-07-01T19:50:47.521Z&fh=2020-02-12T19:50:47.526Z&provincia=0&tcompra=-1&ucompra={"disabled":true}"],"selectors":[{"id":"Descriptions","type":"SelectorText","parentSelectors":["_root"],"selector":"td[ng-bind-html]","multiple":true,"regex":"","delay":0}]}

You can use the "Click Next Page button" method for this. It uses Click Type: Click More. I'm using the main table as the selector, then placing row wrappers and data scrapers within it. I also made the row wrappers a child of _root so that it will scrape the first page. For testing I had changed the Url to produce fewer results. You can change it back to your original Url. I used Page load delay: 5500.

Thank you so much! I totally get it now

thanks, this also helped me. But one additional question: i need the corresponding page number in each row scraped from the wrapper. Could you help me on that?

You can try:
Type: Text
Selector: ul > li[ng-repeat][class='pagination-page active']
Multiple: NO
Parent selectors: Both _root and Paginator (same as for Row wrappers)
