並在freemarker

Question

是否有可能和（& &）freemarker或我必須使用嵌套的if？

<#if object?exists > 


</#if> 

Answer 1

您可以自由使用製造商& &作爲邏輯運算符。見Logical operations

例如

<#if x < 12 && color = "green"> 
    We have less than 12 things, and they are green. 
</#if> 
<#if !hot> <#-- here hot must be a boolean --> 
    It's not hot. 
</#if>
