我尝试在一些改动之后刷新数据，但我得到的是ng-repeat中的dupes错误。
案件是;
我尝试构建动态菜单模块
您需要添加，删除，更改订单并分配给其他主菜单项等。
除了在表格中重新加载菜单结构外，一切都有效。
我清除原始对象，表卸载并显示没有数据，然后我尝试以更改的形式重新加载数据，并出现dupes错误。重新编码浏览器后，所有内容都会按原样更新并正确显示，直到下次更新。
我无法真正推送和拼接数组，因为缩进因为订单可能只是改变了
代码
模块
"use strict";
// no dependencies
angular.module('appWebmenu', []);
主要指令
'use strict';
angular.module('appWebmenu').directive('appWebmenu',function() {
return {
scope:false,
controller: 'appWebmenuController',
templateUrl: 'external/appWebmenu/appWebmenuTemplate.html'
};
});
列表指令实际表范围已移至模块控制器
angular.module('appWebmenu').directive('appWebmenuList', function() {
return {
transclude: true,
templateUrl: 'external/appWebmenu/appWebmenuListTemplate.html',
controller: 'appWebmenuController',
scope: false
}
});
模板
<div ng-if="!listLoaded">
<i class="fa fa-spinner fa-spin fa-3x"></i>
</div>
<div ng-if="listError">
{{ 'ERROR_LOADING' | translate }}
</div>
<div ng-if="listLoaded && !listError && itemList">
<table class="webmenu-table-main">
<thead>
<tr>
<th>{{'PAGE' | translate}}</th>
<th>{{'LANGUAGE' | translate}}</th>
<th>{{'ACTIONS' | translate}}</th>
</tr>
</thead>
<tbody>
<tr ng-repeat='item in itemList'>
<td>{{item.sub}}{{item.menu_name}}</td>
<td>{{item.lang_name}}</td>
<td>
<i class="fa fa-pencil-square" title="{{ 'EDIT' | translate }}" ng-click="details(item.menu_id)" ng-if="item.menu_is_editable != '0'"></i>

我尝试跟踪$ index，跟踪数组中的一些独特项目（menu_id），但没有区别，或实际上使情况变得更糟。
我希望有人可以帮我解决这个问题。
答案 0 :(得分：0)
我发现了问题。生成错误，因为php返回输出两次。所以确实存在重复，因为重复了json对象。我想是菜鸟错误。我忘了清除一个变量。
很奇怪虽然是在单独的请求之间，但是仍保留了php中的内部类变量。
