每个＃和每个handlbars之外的变量 [英] Variables outside of #each with handlbars

问题描述

我有数据，

I have the data,

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。

I'm my template I loop through items, but want to access the current value while in the loop.

这不起作用，

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

推荐答案

href =http://handlebarsjs.com/#paths =nofollow>精细的手册：

From the fine manual:

嵌套handlebars路径也可以包含 ../ 段，它们根据父上下文评估路径。

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

所以你想用 {{../ current}} 来存取 current的值在父上下文中。

So you want to use {{../current}} to access the value of current in the parent context.
