PbootCMS常用if条件判断语句总结分享，导航菜单高亮等

{pboot:if(’[nav:scode]’==’{sort:tcode}’)}class=“active”{/pboot:if} //用于非首页

//完整示例

{pboot:nav}[nav:name]{/pboot:nav}

{pboot:if([nav:soncount]>0)}…{/pboot:if}

{pboot:nav}

<li><a href=”[nav:link]”>[nav:name]</a> //一级菜单循环

{pboot:if([nav:soncount]>0)}  <//当有子菜单时显示div

<div>

{pboot:2nav parent=[nav:scode]}

<a href=”[2nav:link]”>[2nav:name]</a> //二级菜单循环

{/pboot:2nav}

</div>

{/pboot:if}

</li>

{/pboot:nav}

{pboot:nav}

<li><a {pboot:if([nav:soncount]>0)} href=”javascript:;” {else} href=”[nav:link]” {/pboot:if}>[nav:name]</a></li>

//无子菜单时显示正常链接，有子菜单时为空连接，用于手机端点击菜单滑出子菜单情况。

{/pboot:nav}

{pboot:if(’[nav:scode]’==’{sort:scode}’)}class=“active”{/pboot:if}

//例：

{pboot:nav parent={sort:tcode}}

<li {pboot:if([nav:scode]=={sort:scode})}class=”active”{/pboot:if}><a href=”[nav:link]”>[nav:name]</a></li>

{/pboot:nav}

{pboot:if({pboot:companyqq}!=)}QQ：{pboot:companyqq}{/pboot:if}

{pboot:if({page:rows}>0)}{page:bar}{else}暂无内容{/pboot:if}

例：

{pboot:if({page:rows}>0)}

<div class=”page”>        

<a href=”{page:index}”>首页</a>

<a href=”{page:pre}”>上一页</a>

{page:numbar}

<a href=”{page:next}”>下一页</a>

<a href=”{page:last}”>尾页</a>

</div>

{else}

<div class=”page”>暂无内容</div>

{/pboot:if}

{pboot:if({page:rows}>0)}

<div class=”page”>

<a href=”{page:index}”{pboot:2if({page:current}==1)}class=”hide”{/pboot:2if}>首页</a>  <!–在第一页时，当前页码‘{page:current}’等于1，添加‘hide’样式，.hide{dispaly:none;}–>

<a href=”{page:pre}”{pboot:2if({page:current}==1)}class=”hide”{/pboot:2if}>上一页</a>  <!–与上条同理–>

{page:numbar}

<a href=”{page:next}”{pboot:2if({page:current}=={page:count})}class=”hide”{/pboot:2if}>下一页</a>  <!–在最后一页时，当前页码‘{page:current}’等于总页数‘{page:count}，’添加‘hide’样式，.hide{dispaly:none;}–>

<a href=”{page:last}”{pboot:2if({page:current}=={page:count})}class=”hide”{/pboot:2if}>尾页</a><!–与上条同理–>

</div>

{else}

<div class=”page”>暂无内容</div>

{/pboot:if}

{pboot:if(’[xx:i]’==‘1’)}class=“active”{/pboot:if}

<!–第一个菜单添加 class=”active”–>

{pboot:nav}

<a href=”[nav:link]” {pboot:if([nav:i]==1)}class=”active”{/pboot:if}>[nav:name]</a>

{/pboot:nav}

<!–第一条文章添加 class=”active”–>

{pboot:list}

<a href= “[list:link]” {pboot:if([list:i]==1)}class=”active”{/pboot:if}>[list:title]</a>

{/pboot:list}

<!–第一个轮播图添加 class=”active”–>

{pboot:slide gid=* num=*}

<img src=”[slide:src]” {pboot:if([slide:i]==1)}class=”active”{/pboot:if}>

{/pboot:slide}

<!–以上具体 [xx:i] 用法请参考官方手册，也可以用 jq 的选择器 + addclass–>

{pboot:if({content:ispics}==1)}…多图…{else}…缩略图…{/pboot:if}

例：

{pboot:if({content:ispics}==1)}

<ul>

{pboot:pics id={content:id} num=5}

<li><img src=”[pics:src]” /></li>  <!–多图循环–>

{/pboot:pics}

</ul>

{else}

<img src=”{content:ico}” />  <!–缩略图–>

{/pboot:if}

{pboot:if(’[list:link]’==’{content:link}’)}class=“active”{/pboot:if} //判断列表内链接等于本文链接

例：

<ul>

{pboot:list scode={sort:tcode} num=10 order=visits}

<li {pboot:if([list:link]=={content:link})}class=”active”{/pboot:if}><a href=”[list:link]”>[list:title]</a></li>

{/pboot:list}

</ul>

{pboot:if([list:i]%2==0)}…{/pboot:if}

例：

<ul>

{pboot:list num=10}

<li {pboot:if([list:i]%2==0)}class=”bg-dark”{/pboot:if}><a href=”[list:link]”>[list:title]</a></li>  <!–等于0为偶数，等于1为奇数  .bg-dark{background:#000;}–>

{/pboot:list}

</ul>

{{pboot:if(’[nav:i]’>‘2’)}……{/pboot:if} //从第二个开始

例：

{pboot:nav}

{pboot:if([nav:i]>2)}

<li><a href=”[nav:link]”>[nav:name]</a></li>

{/pboot:if}

{/pboot:nav}

{pboot:if([nav:scode]==2||[nav:scode]==4||[nav:scode]==6)}style=“display: none;”{/pboot:if} //隐藏 scode 为 2，4，6 的菜单

例：

{pboot:nav}

<li {pboot:if([nav:scode]==2||[nav:scode]==4||[nav:scode]==6)}style=”display: none;”{/pboot:if}><a href=”[nav:link]”>[nav:name]</a></li>
