     } 
    ] 
} 
]

但我怎么也找不到可以NG-重复theese。当我写{{data.sender}}在控制台中返回错误[ngRepeat：dupes]。

我需要名单票列表页面这个值，这是用户一个支持系统。

NG重复= “数据项|轨道由$指数” - 尝试TRACK BY） – KoIIIeY

请出示所有相关的代码 – charlietfl

NG重复= “在DATAS数据” 按部就班地进行，$指数 – Akis

你得到在控制台[ngRepeat:dupes]错误，因为数据中有一些重复。

如果你通过所有的数据要循环，并显示sender，你可以做这样的事情

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

$index跟踪使用数组中的对象的索引数组中的每个对象。

这是完全正确的答案。 –

假设您的对象位于变量$ scope.data的值中。

然后你就可以在与角度您的HTML渲染这个如下：

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

更新：事实上，与此特定错误，您通过$索引需要跟踪

' {{data.id}} ' 我已经试过了。错误'angular.js：13920错误：[ngRepeat：dupes] http：//errors.angularjs.org/1.5.8/ngRepeat/dupes？p0 = dataa％20in％20datas＆p1 = object％3Anull＆p2 = null' –

ng -repeat =“在DATAS数据”按部就班地进行，$ index' – Akis

@Akis它是否符合这种类型真实 'NG重复=“数据DATAS轨道由$指数”' 感谢您的回答，谢谢解决方案@Akis –

试试这个， Here is working fiddle。
也检查角度版本，它应该至少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>
