如何在Freemarker中使用字符串列表

Question

我试图使用一个行业列表来确定输出文本。例如，如果行业是分发&批发或eCommerce或制造显示一些文本，否则显示一些其他文本。

下面的代码有一些问题：

<#if (customer.custentity_esc_industry)=["Distribution \a Wholesale","eCommerce","Manufacturing"]>some text<#else>some other text</#if>

但是我似乎不能让它正常工作..。有什么想法吗？

Answer 1

<#if ["Distribution \a Wholesale", "eCommerce", "Manufacturing"]
         ?seq_contains(customer.custentity_esc_industry)>
  some text
<#else>
  some other text
</#if>

甚至(?then需要2.3.23)：

${["Distribution \a Wholesale", "eCommerce", "Manufacturing"]
  ?seq_contains(customer.custentity_esc_industry)
  ?then("some text", "some other text")}

Answer 2

你可以这样做：

<#assign sequence = ["Distribution \a Wholesale","eCommerce","Manufacturing"] />
<#assign flag = 0 />
<#list sequence as seq>
     <#if customer.custentity_esc_industry == seq>
          <#assign flag =1>
          <#break />
     </#if>
</#list>
<#if flag == 1>
     //some text
<#else>
     //some other text
</#if>
