Scrapping pagination

Hi. I've recently start a scrapping project, so I've run in one problem. The page have a jquery pagination so when you open the page for the first time, on the page there are 20 products(this products I can scrap). After scrolling down the page when you reach the footer of the page, the jquery is triggered so add new products below the first 20 i.e pagination works on the same page. My question is: How I can scrap the all new products which comes from the pagination when I scroll down?

Thanks
