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();
};
}
