车把中的嵌套“每个”块

Question

Is there a way to achieve something like this:

{{#each firstArray as |first|}}
  {{#each secondArray as |second|}}
      // this should be value of object from second array with key from first array
    {{second[first]}}  
  {{/each}}
{{/each}}

Answer 1

The lookup helper allows you to lookup first on second .

{{lookup second first}}

Answer 2

Nested each blocks are possible, you refer to the item from the parent array by using this . the initial each uses this because im using an array directly. if it were part of a json object, i would reference the key instead

{{#each this}}
  <ul>
  {{#each this}}
    <li>{{this}}</li>
  {{/each}}
  </ul>
{{/each}}

Answer 3

{{#each column in App.MyController.getColumnValues}}
      {{view App.CountView rowBinding="first" columnBinding="second"}}
