Question

我有一个包含最深层对象的多级数组。

[  
   [  
      [  
         "FUND",
         {  
            "totassets":10.9,
            "totdate":"2015-03-23",
            "expratiogross":1.35,
            "exprationet":1.08
         }
      ],
      [  
         "DAILY",
         {  
            "navdate":"2015-03-23",
            "nav":10.05,
            "chgamt":0,
            "chgpct":0,
            "pop":10.05,
            "ytdreturn":2.03,
            "curr7dayyield":0,
            "eff7dayyield":0,
            "unsub7dayyield":0,
            "30dayyield":0,
            "30dayloadyield":0
         }
      ]
   ]
]

我想使用ngRepeat显示＆＃34; FUND＆＃34;中的所有项目。或＆＃34;每日＆＃34;但我不确定如何深入访问这些对象而没有上面每个数组的名称。

很抱歉，如果这是一个基本问题，但我无法在其他地方找到答案。

Answer 1

您想要获得两个外部数组的第一个元素。

$scope.obj = [  
   [  
      [  
         "FUND",
         {  
            "totassets":10.9,
            "totdate":"2015-03-23",
            "expratiogross":1.35,
            "exprationet":1.08
         }
      ],
      [  
         "DAILY",
         {  
            "navdate":"2015-03-23",
            "nav":10.05,
            "chgamt":0,
            "chgpct":0,
            "pop":10.05,
            "ytdreturn":2.03,
            "curr7dayyield":0,
            "eff7dayyield":0,
            "unsub7dayyield":0,
            "30dayyield":0,
            "30dayloadyield":0
         }
      ]
   ]
]

<ng-repeat el in obj[0][0]>
  <span>totassets: {{el[0].FUND.totalAssets}}</span>
  <span>navdate: {{el[0].DAILY.navdate}}</span>
</ng-repeat>

Answer 2

你对数组的一个问题是，即使你忽略外部数组，你仍然会留下两个单独的数组a la：

  [  
     "FUND",
     {  
        "totassets":10.9,
        "totdate":"2015-03-23",
        "expratiogross":1.35,
        "exprationet":1.08
     }
  ],

和

  [  
     "DAILY",
     {  
        "navdate":"2015-03-23",
        "nav":10.05,
        "chgamt":0,
        "chgpct":0,
        "pop":10.05,
        "ytdreturn":2.03,
        "curr7dayyield":0,
        "eff7dayyield":0,
        "unsub7dayyield":0,
        "30dayyield":0,
        "30dayloadyield":0
     }
  ]

因此，您需要两个ngRepeat块来实现我想要实现的目标，并且更深层次以实际访问您想要的值。
