請問在寫自定義導(dǎo)航鏈接的時(shí)候,怎么判斷是否當(dāng)前頁面,如果是,加個(gè)css高亮樣式?下面是結(jié)構(gòu)代碼

{list action=navigator type=1 pid=0 return=n1}

<li class="" >如果是當(dāng)前頁面,添加樣式current-menu-item

<a href="{$n1.url}"><span>{$n1.name}</span></a>

{if $n1.child}

<!--這一句是判斷是否有下級導(dǎo)航-->

<!--循環(huán)下級導(dǎo)航時(shí)，需要把pid=上級的id，renturn=一個(gè)新值，如n2-->

{list action=navigator type=1 pid=$n1.id return=n2}

<ul class="sub-menu">

<li>

<a href="{$n2.url}"><span>{$n2.name}</span></a>

{list action=navigator type=1 pid=$n2.id return=n3}

<ul class="sub-menu">

<li>

<a href="{$n3.url}"><span>{$n3.name}</span></a>

</li>

</ul>

{/list}

</li>

</ul>

{/list} {/if}

</li>

{/list}
