这是我的代码.
$scope.data=[];
$scope.data=[{"label":"name","type":"string"},{"label":"email","type":"string"}];
$scope.addFields = function (field) {
$scope.data.push(field);
};
这是我的HTML： –
<div ng-repeat="eachItem in data">
<input type="button" value="add" ng-click="addFields(eachItem)"/>
<label>{{eachItem.label}}</label>
<input type="text" ng-model="fieldValue"/>
</div>
当我点击添加按钮时,再将另一个对象推入$scope.data数组中
$scope.data=[{"label":"name",{"label":"name","type":"string"}];
在上面我得到了一个错误
angular.min.js:102 Error: [ngRepeat:dupes] http://errors.angularjs.org/1.3.14/ngRepeat/dupes?p0=nestedField%20in%20fie…%2C%22type%22%3A%22string%22%2C%22%24%24hashKey%22%3A%22object%3A355%22%7D at Error (native)
添加后我有重复的对象.因为我想在angularjs.First中使用ng-repeat重复标签名称,我有这样的输出
输出： –
name textBox email textBox
name textBox email textBox name textBox
解决方法
使用$index跟踪
var app = angular.module("app",[])
app.controller('ctrl',['$scope',function($scope){
$scope.data=[];
$scope.data=[{"label":"name","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>
