AngularJS 重复问题数组

Question

我有一个来自 php 的 json 数据 returns，如下所示：

[
{
    "id": 143,
    "sender": "btknctTR",
    "title": "Batıkan Bu nedir bu bu ne bu",
    "date": "Jun 11, 2016 6:47:21 AM",
    "lastupdatedate": "Jun 11, 2016 1:48:54 PM",
    "category": "Sorular",
    "priority": "Kritik",
    "appointedRole": "Moderatör",
    "archived": true,
    "messages": [
        {
            "sender": "btknctTR",
            "message": "Test message",
            "date": "Jun 11, 2016 1:48:30 PM"
        },
        {
            "sender": "btknctTR",
            "message": "This i second test message",
            "date": "Jun 11, 2016 1:48:54 PM"
        }
    ]
},
{
    "id": 198,
    "sender": "btknctTR",
    "title": "Yeni yeni yeniden",
    "date": "Jun 11, 2016 12:53:32 PM",

    "archived": true,
    "messages": [

            "message": "Yeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yenidenYeni yeni yeniden",
            "date": "Jun 11, 2016 7:54:41 PM"
        },
        {
            "sender": "DonduranAtes",
            "message": "asdasd\r\n",
            "date": "Jun 11, 2016 7:54:50 PM"
        },
        {
            "sender": "btknctTR",
            "message": "sadasdasdasd",
            "date": "Jun 11, 2016 7:55:14 PM"
        }
    ]
},
{
    "id": 3810,
    "sender": "btkncttr",
    "title": "asdasdasdasdas",
    "date": "Aug 6, 2016 10:55:36 AM",
    "lastupdatedate": "Aug 7, 2016 10:33:19 PM",
    "category": "Diger",
    "priority": "Normal",
    "appointedRole": "Moderatör",
    "archived": true,
    "messages": [
        {
            "sender": "btkncttr",
            "message": "This is the message",
            "date": "Aug 6, 2016 10:57:07 AM"
        },
        {
            "sender": "player",
            "message": "This is the message tooo",
            "date": "Aug 6, 2016 10:57:07 AM"
        }
    ]
}
]

但我找不到如何 ng-repeat theese。当我写 {{data.sender}} returns 错误 [ngRepeat:dupes] in console.

我需要在工单列表页面列出这些值，这是用户的支持系统。

Answer 1

假设您的对象在变量 $scope.data.

的值中

然后您可以在 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，对于这个特定的错误，您需要通过 $index

进行跟踪

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。

如果你想遍历所有数据并显示sender，你可以这样做

<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。
还要检查 Angular 版本，它应该至少是 1.2，因为它是在那个版本中引入的。

 <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>
