Angularjs 角度UI模式，避免模式范围更改反映在父范围中

我正在构建一个Angular应用程序，我想控制应用程序列表中我想在主页上显示的应用程序。有一个名为“管理应用程序”的部分，我可以在其中管理可见的应用程序

上面的例子解释了我想要实现的目标

我已将json格式的应用程序列表从父范围传递到模式实例。我想对其中一个字段进行更改，

IsPublished

现在的问题是，每当我在模态的isPublished字段中进行更改时，它都会立即反映在父范围中。您可以看到应用程序在覆盖后的父作用域中被过滤

我想避免它。我只想在单击“保存/确定”按钮时反映对父范围的更改

有什么方法可以做到这一点吗？

您需要一个源文件的深度副本使用angular.copy。这些更改直接反映到主屏幕，因为您将$scope.apps与$scope.items绑定，因此两者都引用到同一位置

angular.module('ui.bootstrap.demo', ['ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('ModalDemoCtrl', function ($scope, $modal, $log) {

  $scope.items = ['item1', 'item2', 'item3'];

$scope.apps = [
   {
