paging on popup

If you don't want the page to be refreshed, you have 2 options.
1. Load all records in hidden divs, and make the one that is the current record, visible. You will need jQuery for that, but then again: what's a website without jQuery nowadays?
2. Use AJAX to refresh the contents of the div in your pop-up only. In that case, jQuery also makes life much easier, since it has a few powerful functions to make AJAX requests. From the AJAX function in your view, you call the controller/method that returns the new data. And jQuery takes care of updating the DOM (i.e. the HTML-document).
