addressbookController :
$http({
method: 'GET',
url: '/api/getnewgroup'
})
.then(function (response) {
$scope.draft.groups = response.data;
$scope.groups = response.data; // updated
}, function (response) {
console.log(response);
});
在上面的控制器中,我在 $ scope.draft.groups 中获得json响应,我在另一个名为 profsmsController的控制器中有 draft 对象
profsmsController :
$scope.draft = {
draftType: '',
scheduledTime: '',
senderdata: '',
draftData: {
contacts: ''
},
groups: {
select: false
},
senderName: '',
message: '',
draftName: '',
createdOn: '',
updatedOn: ''
};
如何访问$ scope对象?
我的控制器:
angular
.module('sampleApp.controllers', [])
//addressbook page controller
.controller('addressbookCtrl', function ($http, $scope, $rootScope, $location,
$state, toastr, $timeout, $window, sharedService) {
// Groups
// get group
$http({
method: 'GET',
url: '/api/getnewgroup'
})
sharedService.getDraftPromise().then(function (response) {
$scope.groups = response.data;
$scope.draft.groups = response.data;
}, function (response) {
console.log('error');
});
})
.controller('profsmsCtrl', function ($http, $scope, $rootScope, $location,
$state, toastr, $timeout, $window) {
/* for drafts */
$scope.draft = {
draftType: '',
scheduledTime: '',
senderdata: '',
draftData: {
contacts: ''
},
groups: {
select: false
},
senderName: '',
message: '',
draftName: '',
createdOn: '',
updatedOn: ''
};
//add draft
$scope.addmanualInputDraft = function () {
$http.post('/api/addmanualinputdraft', $scope.draft).then(function (response) {
toastr.success("Added successfully!");
$('.bd-example-modal-lg-manual').modal('hide');
$state.reload();
});
}
})
我的services.js:
angular
.module('sampleApp.services', [])
.factory('sharedService', function ($http) {
var draftPromise = $http({
method: 'GET',
url: '/api/getnewgroup'
});
return {
getDraftPromise: function () {
return draftPromise;
}
};
});
我的app.js:
'use strict';
angular
.module('sampleApp', ['sampleApp.controllers', 'sampleApp.directives','sampleApp.services','sampleApp.filters','ui.router','toastr','ngSanitize', 'ui.select'])
.config(function($stateProvider, $urlRouterProvider, $locationProvider) {
$locationProvider.hashPrefix('');
$urlRouterProvider.otherwise('/dash');
$stateProvider
.state('dash', {
url: '/dash',
templateUrl: 'partials/dash',
})
.state('quicksms', {
url: '/quicksms',
templateUrl: 'partials/quicksms',
controller: 'quicksmsCtrl'
})
.state('professionalsms', {
url: '/professionalsms',
templateUrl: 'partials/professionalsms',
controller: 'profsmsCtrl'
})
.state('file2sms', {
url: '/file2sms',
templateUrl: 'partials/file2sms',
controller: 'file2smsCtrl'
})
.state('addressbook', {
url: '/addressbook',
templateUrl: 'partials/addressbook',
controller: 'addressbookCtrl'
})
});
这是更新的完整代码。我想从地址簿控制器访问$ scope.draft.groups对象。
答案 0 :(得分:2)
一般情况下,您需要创建一个包含共享数据的服务:
myApp.factory('sharedService', function($http) {
var draftPromise = $http({
method: 'GET',
url: '/api/getnewgroup'
});
return {
getDraftPromise: function() {
return draftPromise;
}
};
});
在您的控制器中,您可以通过将其声明为依赖项来使用该服务:
myApp.controller("myController", function($scope, sharedService) {
sharedService.getDraftPromise().then(function(response) {
$scope.draft.groups = response.data;
});
});
两个控制器都将引用draftPromise
的相同实例。
注意:如果您正在缩小代码,则需要使用备用注入使用数组的备用语法。看看official documentation for dependency injection。
