问题描述
这是我厂的:
.factory('userService',()){
var user = {};
return {
getFirstname : function () {
return user.firstname;
},
setFirstname : function (firstname) {
user.firstname = firstname;
}
}
和我在我的两个控制器MainCtrl和AccountEditCtrl使用此服务
我用我的getFirstName()在我的MainCtrl和setFirstname在AccountEditCtrl
And I'm using this service in my two controllers MainCtrl and AccountEditCtrlI'm using my getFirstname() in my MainCtrl and setFirstname in AccountEditCtrl
.controller('MainCtrl',['userService', function(userService){
$scope.userName = userService.getFirstName();
}]);
.controller('AccountEditCtrl',['userService', function(userService){
userService.setFirstname("New First Name");
}]);
我的问题是,当我使用userService.setFirstname()的$ scope.userName不MainCtrl改变。
My problem is that when I use the userService.setFirstname() the $scope.userName don't change in MainCtrl.
推荐答案
在某些情况下,$手表未与工厂对象的工作。比你可以使用更新的事件。
In some case $watch is not working with factory object. Than you may use events for updates.
app.factory('userService',['$rootScope',function($rootScope){
var user = {};
return {
getFirstname : function () {
return user.firstname;
},
setFirstname : function (firstname) {
user.firstname = firstname;
$rootScope.$broadcast("updates");
}
}
}]);
app.controller('MainCtrl',['userService','$scope','$rootScope', function(userService,$scope,$rootScope) {
userService.setFirstname("bharat");
$scope.name = userService.getFirstname();
$rootScope.$on("updates",function(){
$scope.name = userService.getFirstname();
});
}]);
app.controller('one',['userService','$scope', function(userService,$scope) {
$scope.updateName=function(){
userService.setFirstname($scope.firstname);
}
}]);
