<a {if-A:"{page:by}"="time"} class="this" {endif-A} href="{page:linkbytime}">时间</a>
<a {if-A:"{page:by}"="hits"} class="this" {endif-A} href="{page:linkbyhits}">人气</a>
<a {if-A:"{page:by}"="score"} class="this" {endif-A} href="{page:linkbyscore}">评分</a>
效果
<a class="this" href="/index.php?m=vod-list-id-1-pg-1-order--by-time-class--year--letter--area--lang-.html">时间</a>
<a href="/index.php?m=vod-list-id-1-pg-1-order--by-hits-class--year--letter--area--lang-.html">人气</a>
<a href="/index.php?m=vod-list-id-1-pg-1-order--by-score-class--year--letter--area--lang-.html">评分</a>
该段代码意为
如果所在页面为 linkbytime（时间），linkbyhits（人气），linkbyscore（评分），则相应会出现class="this"
