Any idea of how to detect the last element in an "each" with an internal "if"

[jpeter06]

Hello All,
I am using #each, to iterate througt a list.
Aditionally I am filtering the list with an inner #if

Problem: only when de last element is included in the filter the "," is not inserted.
@last cannot be used.
Example of the code

[ 
  {{setVar 'type' (queryParam 'type' '') }}
  {{#each (dataRaw 'zones' )}} 
    {{#if (includes this.type @type)}}
      {"label": "{{this.label}}", "value": "{{this.value}}"}
      {{#unless @last}},{{/unless}}
    {{/if}}
  {{/each}}
]

Thanks in advance :-)

Hi,

The best solution would be to have a filter helper to create an array and then do an each. But we don't have such helper. You can open an issue if you want.

I still found an alternative by creating another variable counting the number of item found:

[ 
  {{setVar 'type' (queryParam 'type' '') }}

  {{setVar 'nb' 0}}

  {{#each (dataRaw 'zones' )}} 
    {{#if (includes this.type @type)}}

    {{setVar 'nb' (add (getVar 'nb') 1)}}

    {{#if (gt @nb 1)}}
      {{#unless @../last}},{{/unless}}
    {{/if}}

    {"label": "{{this.label}}", "value": "{{this.value}}"}

    {{/if}}
  {{/each}}
]

Thanks Guillaume,
I will ask for this "filter" helper. And maybe more things :-D
At the end I finished using a boolean variable:

{{setVar 'addComma' false }}
{{setVar 'extKey' (queryParam 'extKey' '') }}
[
{{#each (dataRaw 'op_zonas' )}}
{{#if (includes this.extKey @extKey)}}
{{#if @addComma}},{{/if}}
{"label": "{{this.label}}", "value": "{{this.value}}"}
{{setVar 'addComma' true }}
{{/if}}
{{/each}}
]
