Hi, and sorry for the noob question! I have an unordered list of 4 links where the links use Ajax.Updater in the onclick: onclick="new Ajax.Updater(''ajaxarea'', ''link1.php'', {asynchronous:true, evalScripts:true }); return false;" How would I go about using addClassName and removeClassName to show the current link? Thanks for any help with this.
