How to send to the top with AjaxPagingNavigator

I want to send to the top of the page each time the user clicks on a page in a AjaxPagingNavigator. I can send via a href="#topofpage" which works for a static link, but setting this value in the href ov my extended PagingNavigator (for GUI customization only) does not work.

What would be the right approach?

You can add to the links in the AjaxPagingNavigator an AjaxEventBehavior which would on click perform the scroll top:

add(new AjaxPagingNavigator("id", pageable){

    @Override
    protected AbstractLink newPagingNavigationLink(String id, IPageable pageable, int pageNumber) {
        AbstractLink link = newPagingNavigationLink(id, pageable, pageNumber); 
        link.add(new AjaxEventBehavior("click") {
            @Override
            protected void onEvent(AjaxRequestTarget target) {
                target.appendJavaScript("$(\"html\").scrollTop(0);");
            }
        });

        return link;
    }

});
