织梦二级栏目增加高亮样式

织梦二级菜单被点击栏目高亮调用方法：

第一步：因为织梦默认dede:channelartlist标签是不支持currentstyle属性的，所以接加下先修改channelartlist.lib.php

1：打开include aglibchannelartlist.lib.php，找到 $pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);

2：在$pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);下增加如下代码

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

第二步：前台调用：

{dede:channelartlist   typeid='47,58,59,70,71,60'  currentstyle='nav_active' }
            <li class="{dede:field.currentstyle/}">
                <a href="{dede:field name='typeurl'/}">
                    <h1>{dede:field name='typename'/}</h1>
                    <!-- <h2>ABOUT</h2> -->
                    <dl>
                    {dede:channel type='son' noself='yes' }
                            <a href="[field:typelink/]">
                                <dd>
                                    <span>
                                        <b>-</b>
                                    </span>[field:typename/]<span>
                                        <b>-</b>
                                    </span>
                                </dd>
                            </a>
                    {/dede:channel}
                    </dl>
                </a>
            </li>
{/dede:channelartlist} 

currentstyle='nav_active'

class="{dede:field.currentstyle/}"
