{dede:channelartlist}                                
            [field:global name=autoindex runphp="yes"](@me%2==0)? @me="<div class=global_module box_r>":@me="<div class=global_module>";[/field:global]

            {dede:arclist titlelen='40' row='11'}    
           <a href="[field:arcurl /]" title="[field:title/]" target="_blank">[field:title /]</a>    
            {/dede:arclist}

        </div>
      {/dede:channelartlist}

循环生产栏目列表,判断第二个就 加个样式<div class=global_module box_r>，否则就<div class=global_module>

貌似 不行，直接输出到页面显示的是
[field:global name=autoindex runphp="yes"](@me%2==0)? @me="":@me="";[/field:global]  

如何解决

[field:global name=autoindex runphp='yes']@me=$GLOBALS['autoindex']%2==0?'<div class="global_module box_r">':'<div class="global_module">';[/field:autoindex]

这样即可
