get array element based on a property in emberjs template

Question

I have an array someArray and I try to get its nth element, where n based on row's property.

{{#each data as |row|}}
  {{someArray.[row.property]}}
{{/each}}

Answer 1

Ember.js' HTMLBars has a get helper that you can use. It doesn't support integer indices, but if you convert it to a string, with the clever use of concat , it should work:

{{#each data as |row|}}
  {{get someArray (concat row.property)}}
{{/each

Answer 2

Handlebars has a lookup helper:

{{#each data as |row|}}
    {{lookup ../someArray row.property}}
{{/each}}
