Question

我有以下JSON文件要阅读，我想只显示我想要的一些特定的JSON文件。

[
  {
     "recommendation_id": "cuhwbchuwbcuhw-ccnahcbhb-12",
     "title": "hellow world",
     "content": "Hello angular",
     "name": "John",
     "home": "USA"
  },
  {
     "recommendation_id": "cuhwcacabchuwbw-ccnahcbhb-32",
     "title": "ng-show",
     "content": "ng-show is amazing",
     "name": "Google",
     "home": "USA"
  },
  ......
  {
     "recommendation_id": "guwqiwu212wbcuhw-ccnahcbhb-12",
     "title": "Awesome",
     "content": "Hello Awesome",
     "name": "Mike",
     "home": "Canada"
  }
]

以下是我使用Jade访问表格标题的方法。

table(id="allRecommendations")
  thead
    tr
      th(ng-repeat='(key, value) in recommendationsAll[1]') {{key}}

输出

recommendation_id     title    content   name    home

但我只想要前三项，它们应如下所示：

recommendation_id     title    content

那么，我的过滤器会错过什么？我有兴趣获取对象属性而不是我的属性详细信息。如何过滤以显示特定的JSON属性？

Answer 1

这将解决问题。

table(id="allRecommendations")
  thead
    tr
      th(ng-repeat="(key, value) in recommendationsAll[1]", ng-show="key == 'recommendation_id' || key == 'title' || key == 'content' " ) {{key}}
