Pagination - adding a "loader" until the next page is loaded

Hi all…
Ok… i have pagination on my page… that loads quite a bit of data. Now when i click on say page 2 or 3 there is a bit of a delay… before the next set of data is loaded … especially on mobile devices…

How can I add a “loading” screen or DIV… while waiting for the next pages data to load fully???
Because going between the pages with pagination… it takes 2 - 3 seconds on older mobiles…

Any clever ideas on is there a on load or on executer then clicking on the numbers itself?
