I wanna update the data and then show the view bound with this controller, the code is as follow
angular.module('myApp.student', ['ngRoute'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/student', {
templateUrl: 'student/student.html',
css: 'student/assets/student.css',
controller: 'studentCtrl',
demand: 'admin'
});
}])
.controller('studentCtrl', ['$scope', 'baseDataUrl', '$http', function($scope, baseDataUrl, $http) {
$scope.update = function() {
$http.get(baseDataUrl + '/student/list').then(function(res) {
$scope.students = res.data;
});
};
$scope.orderProp = "name";
$scope.update();
}]);
how can i do this as there is no way to inject the controller to the config as I know
You could write something like...
angular.module('myApp.student', ['ngRoute'])
.config('routeConfig', function($routeProvider) {
$routeProvider.when('/student', {
templateUrl: 'student/student.html',
css: 'student/assets/student.css',
controller: 'studentCtrl',
demand: 'admin',
resolve: { students : function ($http, baseDataUrl) {
return $http.get(baseDataUrl + '/student/list').then(function (res) {
return res.data;
});
}
}
});
})
.controller('studentCtrl', ['$scope', function($scope, students) {
$scope.students = students;
$scope.orderProp = "name";
}]);
Note that baseDataUrl must either be a constant, or a provider that calls a function to get the required data (in which case, it should be something like baseDataUrl.getUrl()).
With this, it is ensured that every time the /student route is accessed, the scope variable $scope.students contains updated data.

I have my angular routing like th below code
var app = angular.module('mainApp', ['ngRoute']);
app.config(function ($routeProvider) {
$routeProvider.when('/', {
templateUrl: '/DeclarationForms/V1/EmployeeProfile.html',
controller: 'empController'
}).when('/DeclarationAndIndemnityBond.html', {
templateUrl: '/DeclarationForms/V1/DeclarationAndIndemnityBond.html',
controller: 'declarationController'
}).otherwise({
redirectTo: "/"
});
app.controller('empController', function ($scope, $http) {
var resultPromise = $http.get("../ViewForms/GetData/", { params: { ProcName: "SP_EmployeeProfile_GetList" } });
resultPromise.success(function (data) {
console.log(data);
$scope.employeeProfile = data;
});
});
});
The empController calls my controller action with a parameter as per the code
$http.get("../ViewForms/GetData/", { params: { ProcName: "SP_EmployeeProfile_GetList" } });
The controller's action code is as follows
[HttpGet]
[AllowAnonymous]
public ActionResult GetData(string ProcName)
{
if(Session["UserJDRECID"]==null || Session["UserJDRECID"].ToString()=="0")
{
return RedirectToAction("Login", "User_Login");
}
else
{
var UsrJDID = Convert.ToInt32(Session["UserJDRECID"]);
DataSet dt = Helper.PopulateData(ProcName, UsrJDID);
string JSONString = string.Empty;
JSONString = JsonConvert.SerializeObject(dt);
return Json(JSONString, JsonRequestBehavior.AllowGet);
}
}
The form get loaded properly as per the code
templateUrl: '/DeclarationForms/V1/EmployeeProfile.html',
but it don't call my action GetData from where I suppose to bind the EmployeeProfile.html
If I change my angular controller like below code this still don't work
app.controller('empController', function ($scope)
{
console.log("hi"); alert();
});
My console gives below error
Error: error:areq
Bad Argument
Please help me I stuck here.
Thanks in advance.
You can't use "../" inside your $http.get.
I don`t know how your project is setup, but you can try:
$http.get("/ViewForms/GetData/", { params: { ProcName: "SP_EmployeeProfile_GetList" } });
In that case the ViewForms is the name of your controller and it needs to be in the root or pass the complete url. Make sure you are passing all the folders then Controller then your action.
Example: http://www.dotnetcurry.com/angularjs/1202/angular-http-service-aspnet-mvc
I change my code as follows and this worked for me.
var app = angular.module('mainApp', ['ngRoute']);
app.config(function ($routeProvider) {
$routeProvider.
when('/', {
templateUrl: '/DeclarationForms/V1/EmployeeProfile.html',
controller: 'empController'
})
otherwise({
redirectTo: "/"
});
});
app.controller('empController', ['$scope', '$http', EmployeeProfile]);
function EmployeeProfile($scope, $http) {
$http.get("../ViewForms/GetData", { params: { ProcName: "SP_EmployeeProfile_GetList" } })//Done
.then(function (response) {
var mydata = $.parseJSON((response.data));
$scope.employeeProfile = $.parseJSON(mydata);
});
}
I tried a lot and could not find proper answer which can solve my problem. Hope someone will help me out.
app.controller('MainController', ['$scope', 'MainService', 'CONSTANTS', '$routeParams', '$location',
function($scope, MainService, CONSTANTS, $routeParams, $location) {
$scope.indexAction = function() {
MainService.query({format: 'json'}, function(data){
$scope.data = data;
**This data still there when viewAction get call.**
});
}
$scope.newAction = function($event) {
$scope.isNew = true;
angular.isDefined($event)? $event.preventDefault() : false;
if(angular.isDefined($event)) {
var postData = $('#form').serialize();
MainService.save({format: 'json'}, postData, function(data, responseHeader){
var loc = responseHeader('location');
var r = /\d+/;
var dataId = loc.match(r);
$scope.viewAction(dataId[0]);
});
}
else {
$location.path('new');
}
}
$scope.viewAction = function(ObjOrId) {
var dataId = null;
if(angular.isObject(ObjOrId)) {
dataId = ObjOrId.id;
$scope.data = ObjOrId;

});
}
}
$scope.$on('ngRepeatFinished', function(ngRepeatFinishedEvent) {
});
}
]);
app.config(['$routeProvider', '$locationProvider',
function($routeProvider, $locationProvider) {
$routeProvider.
when('/new', {
templateUrl: 'abc.html',
controller: 'MainController'
}).
when('/view/:Id', {
templateUrl: 'xyz.html',
controller: 'MainController'
}).
otherwise({
templateUrl: 'list.html'
})
$locationProvider.html5Mode({
enabled: false
});
}
])
The data which comes in list.html with the help of indexAction that still exists when view route called and I am calling viewAction and loading data from ajax but that new data does not get updated in the view.
Please help!!
Your location.path looks like $location.path('new') when they should look like $location.path('/new');
Your other one looks like $location.path('view/'+dataId) when it should look like $location.path('/view'+ dataId);
I found the answer, I was using ng-model in form template and that was updating the $scope.data object without submitting the form itself, So i changed input directive ng-model to ng-value and while migrating to view template there i am able to get the data.
I am trying to use the code from here to show routes only when a promise is TRUE
I am following this for my directory structure
app
- Orders
-orders.html
-OrderController.js
-OrderService.js
Main-Config [app.js]
var myApp = angular.module('myApp', ['ngRoute','ngAnimate','ui.bootstrap','myApp.OrderController']);
myApp.config(function($routeProvider, $locationProvider){
$locationProvider.html5Mode({
enabled: true,
requireBase: false
});
$routeProvider
.when('/orders', {
templateUrl: 'orders/orders.html',
controller: 'OrderController',
resolve:{
customerExpenses: function(OrderService){
return OrderService.getOrders($route.current.params.customerName);
}
}
})
})
OrderService.js
angular.module('myApp').factory('OrderService', ['$http', function($http) {
var sdo = {
getNames: function() {
var promise = $http({
method: 'GET',
url: ''
});
promise.success(function(data, status, headers, conf) {
return data;
});
return promise;
}
}
return sdo;
}]);
I have tried the Accepted answer from here, and one of the suggestion from another SO article
angular.module('myApp')
.service('FooService', function(){
//...etc
})
.config(function(FooServiceProvider){
//...etc
});
As I have my service in a different file, I am trying to determine if I can use it in app.js file without using provider or is that the only way to use service in app.config?
UPDATE 1:
If i want to use the service in a controller
angular.module('myApp.OrderController',[]).controller('OrderController', function ($scope) {
$scope.displayed=[];
$scope.displayed.push(OrderService.getNames());
});
I get OrderService not available
Have tried this:
angular.module('myApp.OrderController',[]).controller('OrderController', ['$scope','OrderService',function ($scope) {
$scope.displayed=[];
$scope.displayed.push(OrderService.getNames());
}]);
followed example :
angular.
module('myServiceModule', []).
controller('MyController', ['$scope','notify', function ($scope, notify) {
$scope.callNotify = function(msg) {
notify(msg);
};
}]).
factory('notify', ['$window', function(win) {
var msgs = [];
return function(msg) {
msgs.push(msg);
if (msgs.length == 3) {
win.alert(msgs.join("\n"));
msgs = [];
}
};
}]);
but can not use my service. my controller and service are in different files
I added this question here as I feel they are somewaht related.
You have not injected your service OrderService, change your code in very first line
var myApp = angular.module('myApp', ['ngRoute','ngAnimate', ....'OrderService'])
myApp.config(function($routeProvider, $locationProvider, OrderService){
....
})
Rest of the code looks good
I have created countryApp module. I have created "names" array in aboutCtrl.
I want to access "names" array in contactCtrl in insertContact function.
var countryApp = angular.module('countryApp', ['ngRoute']);
countryApp.config(function($routeProvider) {
$routeProvider.
when('/', {
template: '<h1>Home</h1>',
controller: 'homeCtrl'
}).
when('/aboutus', {
templateUrl: 'aboutus.html',
controller: 'aboutCtrl'
}).
when('/contact', {
templateUrl: 'cotacts.html',
controller: 'contactCtrl'
}).
otherwise({
redirectTo: '/'
});
});
countryApp.controller('homeCtrl', function($scope) {
});
countryApp.controller('aboutCtrl', function($scope) {
$scope.names = [{name:'venu',number:'22222',sex:'male'},{name:'Aishu',number:'1111',sex:'female'},{name:'Milky',number:'2222',sex:'female'}]
});
countryApp.controller('contactCtrl', function($scope) {
$scope.greeting = 'Hello, World!';
$scope.insertContact = function () {
alert(names);
}
$scope.resetContact = function () {
}
});
To expand on Claies' solution with actual code:
countryApp.controller('aboutCtrl', function($scope, dataService) {
/* If you're binding the values into your HTML,
you need to $watch the service variable 'names' */
$scope.$watch(function() { return dataService.names }, function() {
$scope.names = dataService.names;
});
dataService.names = [{name:'venu',number:'22222',sex:'male'},{name:'Aishu',number:'1111',sex:'female'},{name:'Milky',number:'2222',sex:'female'}]
});
countryApp.controller('contactCtrl', function($scope, dataService) {
/* You can place the same watch as in aboutCtrl here if
you're displaying stuff in HTML that's related to this controller */
$scope.greeting = 'Hello, World!';
$scope.insertContact = function () {
alert(dataService.names);
}
$scope.resetContact = function () {
}
});
countryApp.service('dataService', function() {
var dataObj = {};
dataobj.names = [];
return dataObj;
});
Do notice the comments about $watching the service variable; if you want to display the values in the view through a $scope variable, you'll need to $watch the corresponding service variable or the $scope variable won't be updated when the value of the service variable changes.
If you want to communicate between two controllers, then please take reference of the following fiddle:
Fiddle : http://jsfiddle.net/VaibhavP17/nky45/
It shows how to communicate between the two controllers and also the nuances of events. I hope this helps :)

In addition to the actual error explained by #dave, if you want eror messages to be more explicit without having to follow a link, you should use angular.js instead of angular.min.js (the minimized one) for your development environment.
If you follow the link in the error, you will see
Argument 'hospitalController' is not a function, got undefined
It sounds like you have in your html somewhere:
ng-controller="hospitalController"
but you haven't created a controller with that name.
