目的：

判斷是否有下載鏈接和判斷是否有官網(wǎng)鏈接，如果沒有就顯示不同的圖標和不能點擊跳轉(zhuǎn)。

實現(xiàn)代碼：

<div class="btn-group btn-group-justified m-b {dede:field.baiduyun runphp='yes'}if(@me ==''){@me='normal-cursor';}else{@me='';}{/dede:field.baiduyun}">               <a href="{dede:field.baiduyun/}" class="btn btn-success btn-rounded">                 <i class="{dede:field.baiduyun runphp='yes'}if(@me ==''){@me='fa fa-times';}else{@me='icon-cloud-download';}{/dede:field.baiduyun}"></i> 百度云               </a>               <a {dede:field.guanwang runphp='yes'}if(@me ==''){@me='';}else{@me='"href="'@me'"';}{/dede:field.guanwang} class="btn btn-dark btn-rounded {dede:field.guanwang runphp='yes'}if(@me ==''){@me='normal-cursor';}else{@me='';}{/dede:field.guanwang}">                 <i class="{dede:field.guanwang runphp='yes'}if(@me ==''){@me='fa fa-eye-slash';}else{@me='fa fa-eye';}{/dede:field.guanwang}"></i> 官網(wǎng)/Store               </a>             </div>

主要代碼：

{dede:field.baiduyun runphp='yes'}if(@me ==''){@me='normal-cursor';}else{@me='';}{/dede:field.baiduyun}
