I am trying to implement textbox autocomplete functionality in MVC angularjs. I have see examples with angucomplete method but it gets all db values in one shot. When I hit the key back again it doesnt go to MVC controller action.
Below is my code view code:
<div ng-controller="sampleController">
<div ng-app="medAapp" ng-controller="sampleController">
<div angucomplete-alt id="txtautocomplete" placeholder="Type Country name" pause="100" selected-object="AfterSelectedCoutries" local-data="countries" search-fields="Country" title-field="Country" minlength="1" input-class="form-control" match-class="highlight">
</div>
<div ng-show="SelectedCountries">
Selected Country: {{SelectedCountries.Country}}
</div>
</div>
</div>
Module code:
var medApp = angular.module("medApp", ['angucomplete-alt', 'ui.grid', 'ui.grid.pagination', 'ui.grid.selection', 'ui.grid.exporter',
'ui.grid.grouping', 'ui.grid.expandable']);
Angular Controller code:
medApp.controller("sampleController", ['$scope', '$http', function ($scope, $http) {
$scope.countries = [];
$scope.SelectedCountries = null;
$scope.AfterSelectedCoutries = function (selected) {
if (selected) {
$scope.SelectedCountries = selected.originalObject;
}
}
$http.get("/Home/GetCountry").then(function (d) {
$scope.countries = d.data;
}, function (error) {
alert('Failed');
})
}])
MVC Controller code:
public JsonResult Getcountry()
{
List<Item> listcountry = new List<Item>()
{
new Item()
{
Id=1,
Name= "Crocin"
},
new Item()
{
Id=2,
Name= "Bruffen"
}
};
return Json(listcountry, JsonRequestBehavior.AllowGet);
}
My question is GetCountry method should have a parameter to get the required records but in none of the samples it does.
Any suggestions??
Thanks

I need to pass an object from one controller to another and have used this solution but it is not working.
Here the code:
angular.module("customerApp", [])
.controller('MainCtrl', function ($scope, myService, $http, $location) {
var vm = this;
vm.pinFormCheck = function () {
vm.count++;
if (vm.pinForm.$valid && vm.details.PIN === vm.pin && vm.count <= 2) {
location.href = "http://localhost:51701/Home/MainMenu";
$scope.obj = {
'cid': 'vm.details.CID',
'name': 'vm.details.Name',
'pin': 'vm.details.PIN',
'bal': 'vm.details.Bal',
'status': 'vm.details.cardStatus'
};
console.log(vm.details.Bal);//the correct balance get displayed in console
} else {
vm.failPin = true;
}
};
})
.controller('CheckCtrl', function ($scope, myService) {
$scope.data = myService.getObj();
})
.factory('myService', function () {
var obj = null;
return {
getObj: function () {
return obj;
},
setObj: function (value) {
obj = value;
}
}
});
Here is the view from which the first object is passed:
<body ng-app="customerApp">
<div ng-controller="MainCtrl as vm">
<form name="vm.pinForm">
<input type="password" ng-model="vm.pin" ng-required="true" />
<p><button ng-disabled="vm.count >=3" ng-click="vm.pinFormCheck();" ng-init="vm.count=0">Proceed</button></p>
</form>
...
Here' the second view where I need the object
<html ng-app="customerApp">
<body ng-controller="CheckCtrl">
<div>
<h1>your balance is {{data.bal}}</h1>
....
The balance from vm.details.Bal from the first view must appear in data.bal in the second view, but nothing is appearing.
You can just save vm.details in some factory.
And then get it in CheckCtrl from this factory.
Factories in AngularJS implement singleton pattern. So saved data will be kept in until your app exists.
You tried to do next thing myService.getObj(); But you didn't save anything to the service.
Inject myService to the MainCtrl and then save details into it.
My spring mvc controller returns an object.
My scenario is:
On click of a button from one page say sample1.html load a new page say sample2.html in the form of a table.
In sample1.html with button1 and controller1--> after clicking button1-->I have the object(lets say I got it from backend) obtained in controller1.
But the same object should be used to display a table in sample2.html
How can we use this object which is in controller1 in sample2.html?
You can use a service to store the data, and inject it in your controllers. Then, when the value is updated, you can use a broadcast event to share it.
Here is a few example:
HTML view
<div ng-controller="ControllerOne">
CtrlOne <input ng-model="message">
<button ng-click="handleClick(message);">LOG</button>
</div>
<div ng-controller="ControllerTwo">
CtrlTwo <input ng-model="message">
</div>
Controllers
function ControllerOne($scope, sharedService) {
$scope.handleClick = function(msg) {
sharedService.prepForBroadcast(msg);
};
}
function ControllerTwo($scope, sharedService) {
$scope.$on('handleBroadcast', function() {
$scope.message = sharedService.message;
});
}
Service
myModule.factory('mySharedService', function($rootScope) {
var sharedService = {};
sharedService.message = '';
sharedService.prepForBroadcast = function(msg) {
this.message = msg;
this.broadcastItem();
};
sharedService.broadcastItem = function() {
$rootScope.$broadcast('handleBroadcast');
};
return sharedService;
});
JSFiddle demo
you can use factory to share data between controllers
<div ng-controller="CtrlOne">
<button ng-click="submit()">submit</button>
</div>
<div ng-controller="CtrlTwo">
{{obj}}
</div>
.controller('CtrlOne', function($scope, sampleFactory) {
$scope.sampleObj = {
'name': 'riz'
}; //object u get from the backend
$scope.submit = function() {
sampleFactory.setObj($scope.sampleObj);
}
})
.controller('CtrlTwo', function($scope, sampleFactory) {
$scope.obj = sampleFactory.getObj();
})
.factory('sampleFactory', function() {
var obj = {};
return {
setObj: function(_obj) {
obj = _obj;
},
getObj: function() {
return obj;
}
}
})
// I have written java code to fetch data from mongo-db. What i need to do is on tick of checkbox button i have to display those data in drop-down menu using angular-js and bootstrap. Nothing is happening after doing these code.
.html page
<div ng-controller="release">
<div class="col-md-2 col-centered col-fixed">
<label for="cloneRelease" translate="release.form.cloneRelease">CloneRelease</label>
</div>
<div>
<input type="checkbox" ng-model="ticked">
<div class="dropdown-menu" ng-repeat="release in releaseName" ng-show="ticked">{{release.name}}</div>
</div>
</div>
controller.js
releaseApp.controller('release', function($scope, $location, $http, ReleaseNameService){
$scope.releaseName = [];
init();
function init(){
ReleaseNameService.getReleaseName().then(function(data){
$scope.releaseName = data;});
console.log('inside controller: '+$scope.releaseName);
}
});
service.js
releaseApp.factory('ReleaseNameService', function($http){
var releaseName = [];
var factory = {};
factory.getReleaseName = function(){
return $http.get('release/fetchAllReleaseDetails').then(function(response){
releaseName = response.data;
console.log('inside service method'+ releaseName);
return releaseName;
});
};factory;
});
It is simple, u need to bind checkbox with ng-model:
<input type="checkbox" ng-model="ticked">
If its ticked $scope.ticked return true, else return false. If true show data, if false hide it (with ng-show)
Here is an example in jsFiddle without css ofc.
http://jsfiddle.net/RLQhh/2282/
UPDATE:
recreateing case with service.
service.js
app.factory('dataService', function ($http) {
var dataObject= {
async: function () {
var promise = $http.get('data/').then(function (response) {
return response;
});
return promise;
}
};
return dataObject;
})
controller.js
$scope.dataTest = [];
$scope.ticketed = false;
var getData = function(){
dataService.async().then(function (d) {
$scope.dataTest = d.data;
});
}
getData();
html
<input type="checkbox" ng-model="ticketed">
<div ng-show="ticketed" ng-repeat="dat in dataTest">
{{dat.name}}
</div>
...this is tested case so it should work with yours
You can make a REST call to fetch the data from your java function and store it in scope.Then you can use ng-repeat to display data in dropdown.
Here is a very good article on how to do it.

I've been struggling with the following problem:
I'm trying to delete a 'Post' item from a Firebase Array with the $remove AngularFire method which I have implemented in a Angular Service (Factory). This Post is a child of 'Event', so in order to delete it I have to pass this Service a argument with the relevant Event of which I want to delete the post.
This is my controller:
app.controller('EventSignupController', function ($scope, $routeParams, EventService, AuthService) {
// Load the selected event with firebase through the eventservice
$scope.selectedEvent = EventService.events.get($routeParams.eventId);
// get user settings
$scope.user = AuthService.user;
$scope.signedIn = AuthService.signedIn;
// Message functionality
$scope.posts = EventService.posts.all($scope.selectedEvent.$id);
$scope.post = {
message: ''
};
$scope.addPost = function (){
$scope.post.creator = $scope.user.profile.username;
$scope.post.creatorUID = $scope.user.uid;
EventService.posts.createPost($scope.selectedEvent.$id, $scope.post);
};
$scope.deletePost = function(post){
EventService.posts.deletePost($scope.selectedEvent.$id, post);
// workaround for eventService bug:
// $scope.posts.$remove(post);
};
});
And this is my Service (Factory):
app.factory('EventService', function ($firebase, FIREBASE_URL) {
var ref = new Firebase(FIREBASE_URL);
var events = $firebase(ref.child('events')).$asArray();
var EventService = {
events: {
all: events,
create: function (event) {
return events.$add(event);
},
get: function (eventId) {
return $firebase(ref.child('events').child(eventId)).$asObject();
},
delete: function (event) {
return events.$remove(event);
}
},
posts: {
all: function(eventId){
var posts = $firebase(ref.child('events').child(eventId).child('posts')).$asArray();
return posts;
},
createPost: function (eventId, post) {
// this does work
var posts = $firebase(ref.child('events').child(eventId).child('posts')).$asArray();
return posts.$add(post);
},
deletePost: function (eventId, post) {
// this does not work
var posts = $firebase(ref.child('events').child(eventId).child('posts')).$asArray();
return posts.$remove(post);
}
}
};
return EventService;
});
When I try to delete the link tag just freezes and no error logging appears in the console. While if I call $remove on my $scope.posts directly in my controller it magically works.. Furthermore my Post is not removed from my Firebase DB.
Another weird thing is that 'CreatePost' works perfectly fine using the same construction.
My view:
<div class="col-xs-8 col-xs-offset-2 well">
<form ng-submit="addPost()" ng-show="signedIn()">
<input type="text" ng-model="post.message" />
<button type="submit" class="btn btn-primary btn-sm">Add Post</button>
</form>
<br>
<div class="post row" ng-repeat="post in posts">
<div>
<div class="info">
{{ post.message }}
</div>
<div>
<span>submitted by {{ post.creator }}</span>
delete
</div>
<br>
</div>
</div>
</div>
P.s. I'm not too sure that my 'Service' is implemented in the best possible way.. I couldn't find another solution for doing multiple firebase calls
var posts = $firebase(ref.child('events').child(eventId).child('posts')).$asArray();
within the Post part of my EventService, because it depends on eventId in each CRUD operation. Any ideas would be very welcome :)
The easiest way for me was to use this:
var ref= new Firebase('https://Yourapp.firebaseio.com/YourObjectName');
ref.child(postId).remove(function(error){
if (error) {
console.log("Error:", error);
} else {
console.log("Removed successfully!");
}
});
The only way I'm able to remove the item is using a loop on the array we get from firebase.
var ref= new Firebase('https://Yourapp.firebaseio.com/YourObjectName');
var arr_ref=$firebaseArray(ref);
for(var i=0;i<arr_ref.length;i++){
if(key==arr_ref[i].$id){
console.log(arr_ref[i]);
arr_ref.$remove(i);
}
}
I am just a beginner in Angularjs. I have been trying for consuming WebApi service by angularjs. I am following this
1: http://weblogs.asp.net/dwahlin/using-an-angularjs-factory-to-interact-with-a-restful-service documentation. It has been clearly documented about use of factories and services. I want to perform crud operations and I am following the same way but I am not even getting the methods called in the Api controller and how can I get the data to be listed in the view?
I have done this: My factory is defined in index.cshtml
In the Main view ie. Index.cshtml
#{
ViewBag.Title = "Index";
}
<style>
.container {
float: left;
width: 100%;
}
</style>
<script src="~/Scripts/angular.min.js"></script>
<h2>Practising Angular</h2>
List
Edit
<div ng-app="demoApp">
<div class="container">
<div ng-view=""></div>
</div>
</div>
<script>
var demoApp = angular.module('demoApp', []);
demoApp.config(function ($routeProvider) {
$routeProvider.when('/', { controller: 'SimpleController', templateUrl: 'Home/List' })
.when('/Edit', { controller: 'SimpleController', templateUrl: 'Home/Edit' })
.otherwise({ redirectTo: '/' });
});
demoApp.factory('dataFactory', ['$http', function ($http) {
var urlBase = '/api/Customer';
var dataFactory = {};
dataFactory.getCustomers = function () {
return $http.get(urlBase);
};
dataFactory.getCustomer = function (id) {
return $http.get(urlBase + '/' + id);
};
return dataFactory;
}]);
demoApp.controller('customersController', ['$scope', 'dataFactory', function ($scope, dataFactory) {
$scope.status;
$scope.customers;
getCustomers();
function getCustomers() {
dataFactory.getCustomers()
.success(function (custs) {
$scope.customers = custs;
})
.error(function (error) {
$scope.status = 'Unable to load customer data: ' + error.message;
});
}
}]);
</script>
I have this controller which runs by default as it is an MVC 4.0 project and "Home Controller" and "Index" is defined in the route.
namespace Routing_Angular.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
public ActionResult Index()
{
return View();
}
public ActionResult List()
{
return PartialView();
}
public ActionResult Edit()
{
return PartialView();
}
}
}
The List and Edit Action methods are returned as partialviews because they will act as views to render data in angular js.
So, this is what I have in both of the partial views..
List.cshtml
#{
ViewBag.Title = "List";
}
<h2>Listing the users in order </h2>
<div class="container">
Name: <input type="text" ng-model="filter.name" />
<ul>
<li ng-repeat="objCust in customers | filter:filter.name">{{objCust.name }}-{{objCust.city}}
</li>
</ul>
Customer Name:<br />
<input type="text" ng-model="newCustomer.name" /><br />
Customer city:<br />
<input type="text" ng-model="newCustomer.city" /><br />
<button ng-click="addCustomer()">Add customer</button>
</div>
Edit.cshtml
#{
ViewBag.Title = "Edit";
}
<h2>Edit the particular user. Things are under construction</h2>
<h2>Listing the users in order </h2>
<div class="container">
Name: <input type="text" ng-model="city" />
<ul>
<li ng-repeat="objCust in customers | filter:city">{{objCust.name }}-{{objCust.city}}
</li>
</ul>
</div>
This is the Api controller/Service that is being getting called from Factory in the index.cshtml. But none of the methods are getting called. How the data got from the factory objects will be shown in the View?
ApiController
namespace Routing_Angular.Controllers
{
public class CustomerController : ApiController
{
//
// GET: /Customer/
public HttpResponseMessage Get()
{
CustomerService ObjService = new CustomerService();
var Clients = ObjService.GetClients();
if (Clients.Count < 1) throw new HttpResponseException(HttpStatusCode.NotFound);
return Request.CreateResponse<IEnumerable<tblreferralService>>(HttpStatusCode.OK, Clients);
}
// GET api/customers/5
public HttpResponseMessage Get(int id)
{
CustomerService ObjService = new CustomerService();
var Client = ObjService.GetClient(id);
if (Client == null) throw new HttpResponseException(HttpStatusCode.NotFound);
return Request.CreateResponse<tblreferralService>(HttpStatusCode.OK, Client);
}
}
}
Below I am attaching the image for project structure. It is just a basic structure.
