Help with an AJAX Request in JQuery

I have a JavaScript file that writes an ID to a cookie value. I'd like to use Ajax to lookup and retrieve the title of the ID. Here is what I have but don't know how to do the Ajax request. Any help would be appreciated. The Ajax call should replace ProductArray[x] below. function loadCookieList () { var CookieValString = $.cookie(CookieName); var TheHTML = '<li class="nav-header">Saved Listings</li>'; if (CookieValString) { var ProductArray = [login to view URL]('|'); [login to view URL](); for (var x in ProductArray) { $.ajax({ type:'GET', url:'/js/[login to view URL]', data:{ProductArray[x]}, success: function(data) { alert('success'); } ); TheHTML += '<li style="margin-bottom:6px;"><a style="display:inline;" href="[login to view URL]'+ProductArray[x]+'">'+ProductArray[x]+'</a> <span class="Delete" id="'+ProductArray[x]+'"><i class="icon-remove-sign"></i></span></li>'; } $('.span3 .sidebar-nav').show(); } else { $('.span3 .sidebar-nav').hide(); }
