让织梦channelartlist标签也支持currentstyle高亮显示的方法

$pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);

if($typeids[$i]['id'] == $refObj->TypeLink->TypeInfos['id'] || $typeids[$i]['id'] == $refObj->TypeLink->TypeInfos['topid'] ){
             $pv->Fields['currentstyle'] = $currentstyle ? $currentstyle : 'current';
         }
         else{
             $pv->Fields['currentstyle'] = '';
         }

{dede:channelartlist typeid='2' currentstyle='current'}
 <li class='{dede:field.currentstyle/}'><a href='{dede:field name='typeurl'/}'>{dede:field name='typename'/}</a></li>
{/dede:channelartlist}
