<#list list1 as list>         

       <#if (list.title?length>15)>
         ${list.title[0..15]?default("")}
        <#else>
         ${list.title?default("")}
        </#if>      
        </#list>

 

 

如果实际长度没有13那么长的话加多个if

Template Author's Guide/Expressions.

You can nest if directives (of course):

    

<#if x == 1>

          x is 1 

<#if y == 1>

          and y is 1 too

 <#else>

           but y is not

  </#if>

   <#else>

             x is not 1

     <#if y < 0>

            and y is less than 0

   </#if>

</#if> 

    

Note

How to test if x is greater than 1? <#if x > 1> will bewrong, as FreeMarker will interpret the first > as the end of the tag. Thus, either write<#if (x > 1)> or <#if x &gt; 1>.
