        },
        {
            "sender": "player",
            "message": "This is the message tooo",
            "date": "Aug 6, 2016 10:57:07 AM"
        }
    ]
}
]

但我无法找到如何重复这些。当我写 {{data.sender}} 时，在控制台中返回错误[ngRepeat：dupes]。

我需要在故障单列表页面中列出此值，这是用户的支持系统。

Answer 1

假设您的对象位于变量$ scope.data的值中。

然后你可以在html中使用angular渲染它，如下所示：

<div ng-repeat="item in data track by $index">
    {{ item.id }}
</div>

更新：确实，有了这个特定错误，您需要按$ index跟踪

Answer 2

您在控制台中收到[ngRepeat:dupes]错误，因为数据中存在一些重复项。

如果您要遍历所有数据并显示sender，您可以执行以下操作

<div ng-repeat="data in jsonData track by $index">{{data.sender}}</div>

$index使用数组中对象的索引跟踪数组中的每个对象。

Answer 3

试试这个， Here is working fiddle。
同时检查Angular版本，它应该至少为1.2，因为它是在该版本中引入的。

 <div ng-controller="MyCtrl">
  <div ng-repeat="data in datas track by $index">
    Sender : {{data.sender}}
    <br> Messages :<br>
    <div ng-repeat="(mindex, mvalue) in data.messages">
       {{mindex+1}}. {{mvalue.message}} - {{mvalue.date}}
    </div>
    <br>
  </div>
</div>
