这里是我定义

ProductController

angular.module('ionicApp.controllers', ['ionicApp.config', 'xc.indexedDB'])
    .controller('ProductController',
        function ($scope, $ionicPopup, $timeout,
            $ionicModal, $indexedDB, $window, $ionicModal) {
            $scope.safeApply = function (fn) {
                var phase = this.$root.$$phase;
                if (phase == '$apply' || phase == '$digest') {
                    if (fn && (typeof (fn) === 'function')) {
                        fn();
                    }
                } else {
                    this.$apply(fn);
                }
            };

            var OBJECT_STORE_NAME = constants.productStore;
            $scope.items = [];
            $scope.searchText = "";

            $scope.getAll = function () {

                var myObjectStore = $indexedDB.objectStore(OBJECT_STORE_NAME);

                myObjectStore.getAll().then(function (results) {
                    // Update scope
                    $scope.safeApply(function () {
                        $scope.items = results;
                    });
                });
            };

            $scope.getAll();

            $ionicModal.fromTemplateUrl('search.html', {
                scope: $scope,
                animation: 'slide-left-right'
            }).then(function (modal) {
                $scope.modal = modal;
            });

            $scope.closeModal = function () {
                alert($scope.searchText);
                $scope.modal.hide();
            };

            $scope.openModal = function () {
                //$scope.searchText = "a";
                $scope.getAll();
                $scope.modal.show();
            };

            $scope.closeModal = function () {
                alert($scope.searchText);
                $scope.modal.hide();
            };
            //Cleanup the modal when we're done with it!
            $scope.$on('$destroy', function () {
                $scope.modal.remove();
            });
            // Execute action on hide modal
            $scope.$on('modal.hidden', function () {
                // Execute action
            });
            // Execute action on remove modal
            $scope.$on('modal.removed', function () {
                // Execute action
            });

        })

var app = angular.module('ionicApp', ['ionic', 'ionicApp.controllers']);

app.config(function ($stateProvider, $urlRouterProvider) {
    $stateProvider
        .state('index', {
            url: "/",
            views: {
                'main-view': {
                    templateUrl: "home.html",
                    controller: "AppCtrl"
                }
            }
        })
        .state('product', {
            url: "/product",
            views: {
                'main-view': {
                    templateUrl: "product.html",
                    controller: 'ProductController'
                }
            }
        });

    $urlRouterProvider.otherwise("/");
});

我的问题是

searchText

模型在值更改时没有更新。我尝试了

$watch

，

ng选项

我可以在

openModal

方法上为

$scope.searchText

添加初始值，但输入值后不会更新模型值，因为我的列表不会被过滤

有人能帮我吗

谢谢

我解决了将搜索文本添加到模式中的问题

    $scope.modal = modal;
    $scope.modal.searchText = "";

我将属性更改为新变量

<input type="search" placeholder="busca" ng-model="modal.searchText">

感谢您的支持。

双向绑定最适合嵌套对象。更改绑定以使用如下内容

$scope.data = {};
$scope.data.items = [];

在模态进入作用域之前，仍在请求模态的模板。这可能就是原因

对不起，我是angularjs的新手，我不明白答案您是否尝试查看$scope.modal.searchText？$scope.modal.searchText是未定义的，因为它应该是-我在任何地方都没有看到指定的。ProductController是在哪里实现的？.controller（'ProductController'）（…）我想这里是实现ProductController的地方。你能给我一个jsfiddle吗
