javascript - 带 Handlebars 的 #each 之外的变量

Question

我有数据，

data = {
  "items":  [
      {"value": "New", "id": 1},
      {"value": "Open", "id": 2},
      {"value": "Close", "id": 3}
    ],
  "current": 2
}

我是我的模板，我循环遍历项目，但想在循环中访问当前值。

这不起作用，

{{#each items}}
    {{id}} - {{value}} - {{current}} 
{{/each}}

Answer 1

来自fine manual :

Nested handlebars paths can also include ../ segments, which evaluate their paths against a parent context.

因此您想使用 {{../current}} 来访问父上下文中 current 的值。
