Question

假设我们有以下JSON文件：

{
  "MainRegister": {
    "description": "Hello World",
    "identifier": "01",
    "specifications": [
      {
        "usage": "Retail",
        "other": {
          "type": "Finance",
          "included": "True"
      }
    ]
  }
}

在进行ng-repeat时，我现在如何访问包含中最深的字段？我尝试了以下方法：

<div ng-repeat="entry in entries"> {{entry.description}} <span ng-repeat="specs in entry.specifications"> {{specs.usage}} <span ng-repeat="subspecs in specs.other"> {{subspecs.included}} <span/> <span/> </div>

执行此操作时，{{entry.description}}和{{specs.usage}}将起作用并显示“Hello World”和“Retail”。但是，{{subspecs.included}}不起作用....而且，当嵌套两次以上时，我们就会遇到问题。这是什么解决方案？谢谢

Other是object，而不是collection ...

"other": {
          "type": "Finance",
          "included": "True"
      }

那么，你可以输出specs.other.included吗？

<div ng-repeat="entry in entries">
    {{entry.description}}
    <span ng-repeat="specs in entry.specifications">
      {{specs.usage}}
      <br />
      {{subspecs.other.included}}

    <span/>
</div>

将other作为集合是否有意义？你会有吗？

"other": [{
              "type": "Finance",
              "included": "True"
          },
          {
              "type": "Sport",
              "included": "False"
          }
]

如果没有，请保持原样，然后删除最后一个ng-repeat。

嵌套ng-repeat三次或更多次？
