I want to send data from one controller to another at a certain point. I have looked at the docs and googled before for solutions before posting. But can`t seem to get it to work properly.
I know $emit is for sending events up the scope hierarchy and $braodcast is for telegraphing downwards.
var app = angular.module('App.Controllers', ['ui.bootstrap'])
.controller('FordelaPaBetankandeCtrl',
['$rootScope', '$scope',
function ($rootScope, $scope) {
$scope.$on("delatYrkande", function (selectedValue) {
});
}])
.controller('UtskottCtrl',
['$rootScope', '$scope'
function ($rootScope, $scope) {
}])
.controller('TidlinjeCtrl',
['$rootScope', '$scope'
function ($rootScope, $scope) {
}])
.controller('UserInfoCtrl', ['$scope',
function ($scope){
}])
.controller('VisaSammantradesplanCtrl', ['$rootScope', '$scope',
function ($rootscope, $scope) {
}])
.controller('HanteraGrunddokumentCtrl',
['$rootScope', '$scope',
function ($rootScope, $scope) {
$scope.Emit = function (selectedValue) {
$scope.$emit("delatYrkande", selectedValue);
}
}]);
One approach is to broadcast from $rootScope:
$scope.Emit = function (selectedValue) {
̶$̶s̶c̶o̶p̶e̶.̶$̶e̶m̶i̶t̶(̶"̶d̶e̶l̶a̶t̶Y̶r̶k̶a̶n̶d̶e̶"̶,̶ ̶s̶e̶l̶e̶c̶t̶e̶d̶V̶a̶l̶u̶e̶)̶;̶
$scope.$root.$broadcast("delatYrkande", selectedValue);
}

hi all i using angular js i need to transfer the value from one page controller to another page controller and get that value into an a scope anybody help how to do this
code Page1.html
var app = angular.module("app", ["xeditable", "angularUtils.directives.dirPagination", "ngNotify", "ngCookies","ngRoute"]);
app.controller('Controller1', ['$scope', '$http', '$window', '$filter','$notify','$cookieStore',
function ($scope, $http, $window, $filter, $notify, $cookieStore)
{
$scope.Message="Hi welcome"
}]);
now i want to show scope message into page2 controller
var app = angular.module("app", ["xeditable", "angularUtils.directives.dirPagination", "ngNotify", "ngCookies","ngRoute"]);
app.controller('Controller2', ['$scope', '$http', '$window', '$filter','$notify','$cookieStore',
function ($scope, $http, $window, $filter, $notify, $cookieStore)
{
///here i want get that scope value
}]);
You can use $rootScope instead of $scope:
// do not forget to inject $rootScope as dependency
$rootScope.Message="Hi welcome";
But the best practice is using a service and share data and use it in any controller you want.
You should define a service and write getter/setter functions on this.
angular.module('app').service('msgService', function () {
var message;
this.setMsg = function (msg) {
message = msg;
};
this.getMsg = function () {
return message;
};
});
Now you should use the setMeg function in Controller1 and getMsg function in Controller2 after injecting the dependency like this.
app.controller('Controller1', ['$scope', '$http', '$window', '$filter','$notify','$cookieStore', 'msgService',
function ($scope, $http, $window, $filter, $notify, $cookieStore, msgService)
{
$scope.Message="Hi welcome"
msgService.setMsg($scope.Message);
}]);
app.controller('Controller2', ['$scope', '$http', '$window', '$filter','$notify','$cookieStore', 'msgService',
function ($scope, $http, $window, $filter, $notify, $cookieStore, msgService)
{
///here i want get that scope value
console.log('message from contoller 1 is : ', msgService.getMsg());
}]);
You should use services for it .
Services
app.factory('myService', function() {
var message= [];
return {
set: set,
get: get
}
function set(mes) {
message.push(mes)
}
function get() {
return message;
}
});
And in ctrl
ctrl1
$scope.message1= 'Hi';
myService.set($scope.message1);
ctrl2
var message = myService.get()
Sharing data from one controller to another using service
We can create a service to set and get the data between the controllers and then inject that service in the controller function where we want to use it.
Service :
app.service('setGetData', function() {
var data = '';
getData: function() { return data; },
setData: function(requestData) { data = requestData; }
});
Controllers :
app.controller('Controller1', ['setGetData',function(setGetData) {
// To set the data from the one controller
$scope.Message="Hi welcome";
setGetData.setData($scope.Message);
}]);
app.controller('Controller2', ['setGetData',function(setGetData) {
// To get the data from the another controller
var res = setGetData.getData();
console.log(res); // Hi welcome
}]);
Here, we can see that Controller1 is used for setting the data and Controller2 is used for getting the data. So, we can share the data from one controller to another controller like this.
In the example below, how can I run getData from another controller and have the scope variable in the view updated?
var app = angular.module('app', []);
app.factory('MyService', ['$http',function($http) {
return {
getData: function() {
return $http.get('/api/endpoint');
}
};
}]);
app.controller('MyController', ['$scope', '$http', 'MyService', function($scope, $http, MyService){
MyService.getData().then(function(response){
$scope.myVarialbe = response.data;
});
}]);
app.controller('MyController2', ['$scope', '$http', 'MyService', function($scope, $http, MyService){
///// ?????? How to get $scope.myVarialbe updated from the getData call?
});
}]);
Using $broadcast and $on :
$broadcast dispatches an event name downwards to all child scopes (and their children) and notify to the registered $Scope listeners. The event life cycle starts at the scope on which $broadcast was called. All listeners for the event on this scope get notified.
$on listen on events of a given type. It can catch the event dispatched by $broadcast
app.controller('MyController', ['$scope', '$http', 'MyService', function($scope, $http, MyService){
$scope.$on('variableChanged',function(event, value) {
$scope.myVariable = value;
};
}]);
app.controller('MyController2', ['$scope', '$http', 'MyService', function($scope, $http, MyService){
MyService.getData().then(function(response){
$scope.$broadcast('variableChanged', response.data);
});
}]);
angular.module('app').controller('nav', function($scope,$http) {
$rootScope.$on("CallMethodNavController", function(){
$scope.navMethod();
});
$scope.navMethod=function(){
$http.get('/players').then(function(data) {
$scope.numOfPlayers = data.players.length;
}
});
});
then in the second controller you call this method once a player is added like so:
$rootScope.$emit("CallMethodNavController", {});
i want to test functions in angular js using jasmine. i have created one controller in which one scope function which is given below.
app.controller('NavigationCtrl', ['$scope', '$route', '$rootScope', function ($scope, $route, $rootScope) {
$scope.title="Hello World";
$scope.testMe = function () {
$scope.title = "Welcome";
}
}]);
Also, i want to call above controller function i.e $scope.testMe from another controller using jasmine test case. so, i create another controller and try to call functions from this controller.
app.controller('RunTestCaseCtrl', ['$scope', '$http', '$location', '$route', '$routeParams', '$rootScope', '$timeout', 'MDT_Constant', function ($scope, $http, $location, $route, $routeParams, $rootScope, $timeout, MDT_Constant) {
describe('mycontroller', function () {
beforeEach(module('app'));
it('scopeTestSpec',
inject(function ($controller, $rootScope) {
var $scope = $rootScope.$new();
$controller('NavigationCtrl', {
$scope: $scope
});
$controller.testMe();
expect($scope.title).toEqual('Welcome');
console.log('ok');
}));
});
}]);
this will give the error "module is not defined".
so, how can i call controller method from another controller using jasmine test
Hi I have created two angulerjs files for same ng-app example.
admin.js
var app = angular.module('arcadminmodule', ['ngTable', 'ui-notification']);
app.controller('ArcAdminController', ['$http', '$scope', '$filter', '$interval', 'ngTableParams', 'Notification', function($http, $scope, $filter, $interval, ngTableParams, Notification) {});
admin1.js
var app = angular.module('arcadminmodule');
app.controller('ArcAdminController', ['$http', '$scope', '$filter', '$interval', 'ngTableParams', 'Notification', function($http, $scope, $filter, $interval, ngTableParams, Notification) {});
But its overriding admin.js from admin1.js
please help me out....
In admin1.js when you write:
var app = angular.module('arcadminmodule');
you are not creating a new module. You are trying to get an existing module named 'arcadminmodule'.. If you want to create a new module, you will have to write something like this:
var app = angular.module('arcadminmodule',[]); // add your depencencies...
Now, In your case, in admin.js you are creating your module and admin1,js you are making use of the same module. In angular you cannot have two controllers with the same name. Controllers are for (from the docs):
Set up the initial state of the $scope object.
Add behavior to the $scope object.
So If you need are trying to apply some roles or some business logic, It need to go into one controller. Make sure your controller contain only the business logic needed for a single view.
I think its no need for use the same controller in two places.But you can use services in places.If you need to do some think different from the ArcAdminController,use this structure.

I have been use many services in both controllers,still they are different logics.
I have the following in a controller.
$rootScope.$on('progressbarEvent', function (event, data) {
$rootScope.progresscurrent = data.currentprogress;
console.log('Event listening: ' + $rootScope.progresscurrent);
});
I have this in a factory service.
$rootScope.$emit('progressbarEvent', dataFactory.currentprogress);
$on is returned undefined. Anyone knows the cause of this?
My controller is:
app.controller('indexcontroller', ['$rootScope','$scope', '$http', 'dataFactory',
function ($scope,$http,$rootScope, dataFactory) {
The order of dependencies has to be consistent with the array it was declared in:
app.controller('indexcontroller', ['$rootScope','$scope', '$http', 'dataFactory',
function ($rootScope, $scope, $http, dataFactory) {
