How to get an array value at index using Handlebars.js?

Question

Say I have JSON:

{
userinput: [
    {name: \"brian\", \"value\": \"i like pies\"},
    {name: \"susan\", \"value\": \"memes are stupid\"}
],
feedback: [
             


        

Answer 1

This can be accomplished using the lookup helper:

The lookup helper allows for dynamic parameter resolution using Handlebars variables. This is useful for resolving values for array indexes.

So the template for your example would look like this:

{{#each userinput}}
    {{name}}
    {{value}}
    
        {{#with (lookup ../feedback @index)}}
            {{value}}
        {{/with}}
    
{{/each}}
