Reloading new content while scrolling

Question

Im using the following jQuery, which sets the id of the last item in a UL to \'last_item\'.

function oldest() {
 j(\'ul li:last-child\').addClass( \'last_item\'          


        

Answer 1

You'll need to remove the original "last_item" class from list item before you add it to the new last item...

 j('ul li').removeClass( 'last_item' );
