How to get comma between Freemarker list

I am iterating a java list in freemarker , but I want commas in between the words. Here's my code

<#list key_list[key] as value >${value?js_string}, </#list>

This gives me output as

a,b,c,d,

I want the output in this format:(No comma in the end)

a,b,c,d

How can I get that

Solution

  • You have to include an <#if value_has_next>,</#if> statement.

    This may help:

    <#assign seq = ["winter", "spring", "summer", "autumn"]>
<#list seq as x>
  ${x_index + 1}. ${x}<#if x_has_next>,</#if>
</#list>

    will output:

    1. winter,
    2. spring,
    3. summer,
    4. autumn
