如何在AngularJs中使用ng-repeat重复重复的对象？

杜尔加·西瓦·基肖尔·莫普鲁

这是我的代码。

$scope.data=[];
$scope.data=[{"label":"name","type":"string"},{"label":"email","type":"string"}];
$scope.addFields = function (field) {
   $scope.data.push(field);
  };

这是我的html：-

<div ng-repeat="eachItem in data">
<input type="button" value="add" ng-click="addFields(eachItem)"/>
    <label>{{eachItem.label}}</label>
    <input type="text" ng-model="fieldValue"/>
</div>

当我点击添加按钮时，将另一个对象推入$scope.data数组

 $scope.data=[{"label":"name","type":"string"},{"label":"email","type":"string"},{"label":"name","type":"string"}];

在上面我有一个错误

angular.min.js:102 Error: [ngRepeat:dupes] http://errors.angularjs.org/1.3.14/ngRepeat/dupes?p0=nestedField%20in%20fie…%2C%22type%22%3A%22string%22%2C%22%24%24hashKey%22%3A%22object%3A355%22%7D
at Error (native)

添加后，我有重复的对象。因为我想在angularjs中使用ng-repeat重复标签名称。首先我有这样的输出

输出：

name   textbox
email  textbox

添加按钮后，单击输出：-

name   textbox
email  textbox
name   textbox

使用$ index跟踪

var app = angular.module("app",[])
app.controller('ctrl',['$scope', function($scope){
       $scope.data=[];
$scope.data=[{"label":"name","type":"string"},{"label":"email","type":"string"}];
$scope.addFields = function (field) {
   $scope.data.push(field);
  };
}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app="app" ng-controller="ctrl">
<div class="item item-checkbox">
   <div ng-repeat="eachItem in data track by $index">
<input type="button" value="add" ng-click="addFields(eachItem)"/>
    <label>{{eachItem.label}}</label>
    <input type="text" />
</div>    
</div>
