javascript - Handlebars 中嵌套的 'each' block

Question

有没有办法实现这样的事情:

{{#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

lookup 帮助程序允许您在second 上查找first。

{{查找第二个优先}}
