Question

I’m writing a JS Array of objects in a Freemarker template. But I am having serious issues not including a comma after the last item.

<#assign pages = module.pages.page>
wh.pages = [
<#list pages as page>
{"name" : "${page.@name}", "href" : "${page.@href}"}
<#if (index+1) < pages?size>,</#if>
</#list>
]

So during the list repeat, while index + 1 is less than the length/size of the pages variable, it should write a comma. So that when it equals the size, it should omit the comma.

So how can this be achieved?

Answer 1

Index has to be prefixed with your item name. In example:

<#if (index+1) < pages?size>,</#if>

should have been:

<#if (page_index+1) < pages?size>,</#if>
