*$type_array = array('newest'=>'最新', 'head'=>'头条', 'focus'=>'焦点', 'recommend'=>'推荐', 'scroll'=>'滚动', 'image'=>'图片'); // 定义列表类型
*$_PAGE['pageon'] = excms_func_page_decode($_GET['page']); //获取分页并解密分页字符串
*$channelid = excms_func_id_decode($channelid); //解密栏目ID。
*$crossid = excms_func_id_decode($_GET['crossid']); //解密交叉栏目。
*$_PAGE_CHANNEL = excms_func_getChannelCacheById($channelid); //根据栏目ID获取栏目缓存。
*$_PAGE_CHANNEL['href'] = ChannelFunction::listName($_PAGE_CHANNEL,1,$_PAGE_CHANNEL['crosschannel']['channelid']); //根据栏目以及交叉栏目获取当前栏
目的链接地址。
*$_PAGE['position'] = ChannelFunction::getNavigation($_PAGE_CHANNEL['original_channelid'], $_PAGE['crossid']) . $split_str . *$type_array[$_PAGE['type']]; //根据当前栏目和交叉栏目获取当前导航栏。
