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\taglib\channelartlist.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

1  $pv->Fields['typeurl'] = GetOneTypeUrlA($typeids[$i]);
2                       if($typeids[$i]['id'] == $refObj->TypeLink->TypeInfos['id'] || $typeids[$i]['id'] == $refObj->TypeLink->TypeInfos['topid'] ){  
3                          $pv->Fields['currentstyle'] = $currentstyle ? $currentstyle : 'navOn';  
4                           }  
5                         else{  
6                         $pv->Fields['currentstyle'] = '';  
7                          }  

第二步：前台调用：

 1 {dede:channelartlist   typeid='47,58,59,70,71,60'  currentstyle='nav_active' }
 2             <li class="{dede:field.currentstyle/}">
 3                 <a href="{dede:field name='typeurl'/}">
 4                     <h1>{dede:field name='typename'/}</h1>
 5                     <!-- <h2>ABOUT</h2> -->
 6                     <dl>
 7                     {dede:channel type='son' noself='yes' }
 8                             <a href="[field:typelink/]">
 9                                 <dd>
10                                     <span>
11                                         <b>-</b>
12                                     </span>[field:typename/]<span>
13                                         <b>-</b>
14                                     </span>
15                                 </dd>
16                             </a>
17                     {/dede:channel}
18                     </dl>
19                 </a>
20             </li>
21 {/dede:channelartlist} 

currentstyle='nav_active'

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