Variables outside of #each with handlbars

问题

I have the data,

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

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

This doesn't work,

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

回答1:

From the fine manual:

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

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