我是AngularJS的新手并且遇到过这个问题.

我可以在所有控制器上重新注入我的工厂单例对象吗？

例如：

.factory('medicalCenterService',function(MedicalCenterResource) {

    var medicalCenterService = {};

    medicalCenterService.currentMedCenter = MedicalCenterResource.get();

    medicalCenterService.reloadMedCenter = function() {
        medicalCenterService.currentMedCenter = MedicalCenterResource.get();

        return medicalCenterService.currentMedCenter;
    };

    medicalCenterService.updateMedicalCenter = function(medicalCenter) {
        MedicalCenterResource.updateMedicalCenter(medicalCenter);
        medicalCenterService.currentMedCenter = medicalCenter;
    };

    return medicalCenterService;
})

在MedicalCenterController中,我在应用程序启动时获得带医疗中心的单例对象：

function MedicalCenterController($scope,medicalCenterService) {
    $scope.currentMedCenter = medicalCenterService.currentMedCenter;
}

但后来我尝试在AccountProfileController中编辑医疗中心字段(名称,地址等)

function AccountProfileController($scope,medicalCenterService) {

    $scope.currentMedCenter = medicalCenterService.currentMedCenter;

    $scope.applyMedCenterChanges = function (currentMedCenter) {
        medicalCenterService.updateMedicalCenter(currentMedCenter);
    };
}

而我期望拥有的是具有更新字段的对象.
如何返回我的单身人士的新实例？

你想要这样的东西吗？

.factory('MedicalCenter',function(MedicalCenterResource) {
    var MedicalCenter = function () {
        var center = MedicalCenterResource.get(),update = function() {
                MedicalCenterResource.updateMedicalCenter(center)
            };
        return {
            center: center,update: update
        }    
    };
    return MedicalCenter;

})

function MedicalCenterController($scope,MedicalCenter) {
    center = new MedicalCenter();
    $scope.currentMedCenter = center.center;
}
function AccountProfileController($scope,MedicalCenter) {
    center = new MedicalCenter();
    $scope.currentMedCenter = center.center;
    $scope.applyMedCenterChanges = function () {
        center.update();
    };
}
