Question

我正在尝试将我的数据从控制器1传递到控制器2，但是当我将数据记录到控制器2中时，它返回的值为undefined。之所以使用jquery来请求数据，是因为我使用的是数据表，而且我不知道如何使用angularjs和datatables框架进行事件绑定。我想知道根据控制器1向其发送数据的方式，我对工厂服务的实现是否正确，因为我认为这就是我现在的问题所在。数据没有通过工厂服务。

工厂服务

app.factory('profilingFactory', function() {
    var factoryData = {};
    var factoryModel = {};
    
    factoryData.setModel = function(key, value) {
        factoryModel[key] = value;
    }
    
    factoryData.getModel = function(key) {
        return factoryModel[key];
    };
    
    return factoryData;
    
});

控制器1

app.controller('profilingController', function($scope, $http, $window, profilingFactory) {
    
    $(document).ready(function() {
        
        
        $scope.table = $('#table_profile').DataTable ({
            "ajax": {
                "url": "/getProfilesData",
            },
            "columns": [
                {"data": "applicant_id"},
                {"data": "application_type"},
                {"data": "last_name"},
                {"data": "middle_name"},
                {"data": "first_name"},
                {"data": "birth_date"},
                {"data": "address"},
                {"data": "sex"},
                {"data": "date_applied"},
                {
                    "data": "applicant_id",
                    "mRender":  function (data, type, full) {
                        var editLink = '<button id="editFunc" class="btn btn-primary" type="button" data-id="' + data + '">Edit</button>';
                        //var editLink = '<a id="editFunc" class="editFunction" href="/editProfiles?applicant_id=' + data + '">Edit</a>';
                        var deleteLink = '<button class="btn btn-primary" id="deleteButtonFunc" type="button" data-id="'+ data +'">Delete</button>';
                        return (editLink + " " + "  |  " + " " + deleteLink);
                    }
                }
            ]
        });

        $('body').on('click', '#editFunc', function(e) {
            
            var clickedEdit = $(this);
            var id = clickedEdit.attr("data-id");
            var url = "/editProfiles?applicant_id=" + id;
            var editData = {
                    editId: id
            }
            //$(location).attr('href', url);
            $http.get('/getEditProfilesData/', {params: editData}).then(function(response) {
                //this is orignally what I inteded. I only put a string to test if the service is working
                profilingFactory.setModel('proFactor', response.data);
            });
            
        });
        
        
        $scope.stringXample = "Yeh";
        //$scope.editProfiles = appData;
        
        $('body').on('click', '#deleteButtonFunc', function(e){
        
            var clicked = $(this);
            var id = clicked.attr("data-id");
            
            var deleteData = {
                    deleteId: id
            }
            
            $http.get('/delProfileData/', {params: deleteData}).then(function(response) {
                clicked.parents("tr").remove();
                alert("User info successfully removed");
            });
            //Optional delete Row after 
        });
        
    });

控制器2

app.controller('editProfliesController', function($scope, $http, $window, profilingFactory) {
    $scope.value = profilingFactory.getModel('proFactor');
    console.log($scope.value);
});

Answer 1

我在本地尝试了您的代码。我先了解一下这个问题。

Controller1和Controller2已在初始页面渲染中加载。加载后，Controller2的“功能”将不再执行。在Controller1中完成$ http.get之后，实际上实际上需要再次使其一部分启动。您可以使用 $ watch （https://docs.angularjs.org/api/ng/type/$rootScope.Scope#$watch）来实现。

将 setModel 保留在$ http.get中，并将Controller2逻辑更改为下面，然后重试：

app.controller('editProfliesController', function ($scope, $http, $window, profilingFactory) {
                $scope.$watch(function () { return profilingFactory.getModel('proFactor') }, function (newVal, oldVal) {
                    if (newVal!==oldVal)
                    console.log(newVal);
                });
            });

数据不会通过服务传递给其他控制器
