当使用AngularJS服务尝试在两个 Controller 之间传递数据时，当尝试从该服务访问数据时，我的第二个 Controller 始终会收到未定义的信息。我猜这是因为第一个服务执行$ window.location.href，并且我想这正在清除服务中的数据吗？我是否可以将URL更改为新位置，并将数据保留在第二个 Controller 的服务中？当我运行下面的代码时，第二个 Controller 中的警报始终未定义。
app.js(定义服务的地方)
var app = angular.module('SetTrackerApp', ['$strap.directives', 'ngCookies']);
app.config(function ($routeProvider)
{
$routeProvider
.when('/app', {templateUrl: 'partials/addset.html', controller:'SetController'})
.when('/profile', {templateUrl: 'partials/profile.html', controller:'ProfileController'})
.otherwise({templateUrl: '/partials/addset.html', controller:'SetController'});
});
app.factory('userService', function() {
var userData = [
{yearSetCount: 0}
];
return {
user:function() {
return userData;
},
setEmail: function(email) {
userData.email = email;
},
getEmail: function() {
return userData.email;
},
setSetCount: function(setCount) {
userData.yearSetCount = setCount;
},
getSetCount: function() {
return userData.yearSetCount;
}
};
});
logincontroller.js :( Controller 1在服务中设置值)
app.controller('LoginController', function ($scope, $http, $window, userService) {
$scope.login = function() {
$http({
method : 'POST',
url : '/login',
data : $scope.user
}).success(function (data) {
userService.setEmail("foobar");
$window.location.href = '/app'
}).error(function(data) {
$scope.login.error = true;
$scope.error = data;
});
}
});
appcontroller.js(试图从服务读取值的第二个 Controller )
app.controller('AppController', function($scope, $http, userService) {
$scope.init = function() {
alert("In init userId: " userService.getEmail());
}
});
最佳答案
这样定义您的服务
app.service('userService', function() {
this.userData = {yearSetCount: 0};
this.user = function() {
return this.userData;
};
this.setEmail = function(email) {
this.userData.email = email;
};
this.getEmail = function() {
return this.userData.email;
};
this.setSetCount = function(setCount) {
this.userData.yearSetCount = setCount;
};
this.getSetCount = function() {
return this.userData.yearSetCount;
};
});
