I have two modules with different operations and I tried to work with them as shown below.
<div id="viewBodyDiv" ng-app="xhr">
<div ng-controller="xhrCtrl">
<button ng-click="callAction()">Click</button>
{{sample}}
</div>
</div>
<div id="viewBodyDiv2" ng-app="xhr2">
<div ng-controller="xhr2Ctrl">
<button ng-click="alertMessage()">Click</button>
</div>
</div>
The JS is shown below.
angular.module('xhr', []).controller('xhrCtrl', function ($http, $scope, $window) {
$scope.sample = "sadf";
$scope.callAction = function () {
$http({
method: 'GET',
url: 'Angular/GetData',
params: {
api_key: 'abc'
}
}).then(function (obj) { //I get a text result that I display near the button
$scope.sample = obj.data;
});
};
});
angular.module('xhr2', []).controller('xhr2Ctrl', ['$window','$scope',
function ($window,$scope) {
$scope.alertMessage = function () {
$window.alert("xhr2Ctrl clicked");
};
}]);
When I click on the viewBodyDiv I am getting the desired output but when I click on viewBodyDiv2 the alert message is not getting displayed.
I am new to AngularJS and please let me know what I am doing wrong or what it the procedure to work with two different Modules in Angular.
Thank you.
add this code to the bottom of your JavaScript
angular.element(document).ready(function() {
angular.bootstrap(document.getElementById('viewBodyDiv2'),['xhr2']);
});
Hope this helps.
As per the AngularJS documentation:
https://docs.angularjs.org/api/ng/directive/ngApp
Only one AngularJS application can be auto-bootstrapped per HTML document. The first ngApp found in the document will be used to define the root element to auto-bootstrap as an application.
However, if you still want to do it this way, you have to use angular.boostrap() manually to achieve this. Here is a good tutorial on this:
http://www.simplygoodcode.com/2014/04/angularjs-getting-around-ngapp-limitations-with-ngmodule/
So you need to bootstrap the module to have multiple angular apps on the same page.
You can also inject one of the modules into another.
var xhrModule = angular.module("xhr", ["xhr2"]);
Following is a sample code for bootstrapping the module.
<html>
<head>
<script src="angular.min.js"></script>
</head>
<body>
<div id="viewBodyDiv" ng-app="xhr">
<div ng-controller="xhrCtrl">
<button ng-click="callAction()">Click</button>
{{sample}}
</div>
</div>
<div id="viewBodyDiv2" ng-app="xhr2">
<div ng-controller="xhr2Ctrl">
<button ng-click="alertMessage()">Click</button>
</div>
</div>
<script>
var xhrModule = angular.module("xhr", []);
xhrModule.controller('xhrCtrl', function ($http, $scope, $window) {
$scope.sample = "sadf";
$scope.callAction = function () {
$http({
method: 'GET',
url: 'Angular/GetData',
params: {
api_key: 'abc'
}
}).then(function (obj) { //I get a text result that I display near the button
$scope.sample = obj.data;
});
};
});
var xhr2Module = angular.module("xhr2", [])
xhr2Module.controller('xhr2Ctrl', ['$window','$scope',
function ($window,$scope) {
$scope.alertMessage = function () {
$window.alert("xhr2Ctrl clicked");
};
}]);
angular.bootstrap(document.getElementById("viewBodyDiv2"),['xhr2']);
</script>

I am using ng-click to call a function that request new content for the scope. Im doing that by calling a post request that is handeled by php.
When I run the script I can see the updated data in the console but the page is not being updated.
The HTML;
<body>
<div id ="error_frame" class="system hidden"> </div>
<div ng-controller="objectNavCtrl" id = "content">
<a ng-click="update()">link</a>
</div>
<div ng-controller="objectCtrl" >
<div id="object_container" ng-repeat="object in objects track by object.id">
<div>{{object.name}}</div>
</div>
</div>
</body>
The AngularJS app;
'use strict';
var angular_app = angular.module('angular_app', []);
angular_app.controller('objectCtrl', ['$scope','$http', function ($scope,$http) {
$http({
method: 'get',
url: 'ajax-processor.php'
}).then(function successCallback(response) {
$scope.objects = response.data;
});
}]);
angular_app.controller('objectNavCtrl', ['$scope','$http', function ($scope,$http) {
$scope.update = function(){
console.log('clicked');
$http({
method: 'post',
url: 'ajax-processor.php',
data: {'ajaxKey':'Mykey'}
}).then(function successCallback(response) {
$scope.objects = response.data;
console.log(response.data);
});
}
}]);
I use the get method when the page is loading and try to update it with the update function.
The problem is that two controllers are on separate scopes. Put the common data on the scope of a parent controller:
<body>
<!-- Common scope -->
<div ng-controller="parent as common">
<!-- Separate Scope -->
<div ng-controller="objectNavCtrl" id = "content">
<a ng-click="update()">link</a>
</div>
<!-- Separate Scope -->
<div ng-controller="objectCtrl" >
̶<̶d̶i̶v̶ ̶i̶d̶=̶"̶o̶b̶j̶e̶c̶t̶_̶c̶o̶n̶t̶a̶i̶n̶e̶r̶"̶ ̶n̶g̶-̶r̶e̶p̶e̶a̶t̶=̶"̶o̶b̶j̶e̶c̶t̶ ̶i̶n̶ ̶o̶b̶j̶e̶c̶t̶s̶ ̶t̶r̶a̶c̶k̶ ̶b̶y̶ ̶o̶b̶j̶e̶c̶t̶.̶i̶d̶"̶>̶
<!--use common scope here -->
<div id="object_container" ng-repeat="object in common.objects track by object.id">
<div>{{object.name}}</div>
</div>
</div>
</div>
</body>
angular_app.controller('objectNavCtrl', ['$scope','$http', function ($scope,$http) {
$scope.update = function(){
console.log('clicked');
$http({
method: 'post',
url: 'ajax-processor.php',
data: {'ajaxKey':'Mykey'}
}).then(function successCallback(response) {
̶$̶s̶c̶o̶p̶e̶.̶o̶b̶j̶e̶c̶t̶s̶ ̶=̶ ̶r̶e̶s̶p̶o̶n̶s̶e̶.̶d̶a̶t̶a̶;̶
$scope.common.objects = response.data;
console.log(response.data);
});
}
}]);

You are tracking the changes by id. So as long the object's ids don't change, the page won't be refreshed. Try to leave the track by out or for better performance, do it with some properties you compare or your own comparer function as described here: ng-repeat with track by over multiple properties
I am writing an angularjs app. The requirement is to display the user's data once the user logs in. So when an user successfully logs in, he/she is routed to the next view. My application is working fine upto this point. Now as the next view loads I need to display the existing records of the user. However at this point I see a blank page, I can clearly see in the console that the data is being returned but it is not binding. I have used $scope.$watch, $scope.$apply, even tried to call scope on the UI element but they all result in digest already in progress. What should I do? The page loads if I do a refresh
(function () {
"use strict";
angular.module("app-newslist")
.controller("newsController", newsController);
function newsController($http,$q,newsService,$scope,$timeout)
{
var vm = this;
$scope.$watch(vm);
vm.news = [];
vm.GetTopNews = function () {
console.log("Inside GetTopNews");
newsService.GetNewsList().
then(function (response)
{
angular.copy(response.data, vm.news);
}, function () {
alert("COULD NOT RETRIEVE NEWS LIST");
});
};
var el = angular.element($('#HidNews'));
//el.$scope().$apply();
//el.scope().$apply();
var scpe = el.scope();
scpe.$apply(vm.GetTopNews());
//scpe.$apply();
}
})();
Thanks for reading
you don't show how you're binding this in your template.. I tried to recreate to give you a good idea.
I think the problem is the way you're handling your promise from your newsService. Try looking at $q Promises. vm.news is being updated by a function outside of angular. use $scope.$apply to force refresh.
the original fiddle is here and a working example here
(function() {
"use strict";
var app = angular.module("app-newslist", [])
.controller("newsController", newsController)
.service("newsService", newsService);
newsController.$inject = ['$http', 'newsService', '$scope']
newsService.$inject = ['$timeout']
angular.bootstrap(document, [app.name]);
function newsController($http, newsService, $scope) {
var vm = this;
vm.news = $scope.news = [];
vm.service = newsService;
console.warn(newsService)
vm.message = "Angular is Working!";
vm.GetTopNews = function() {
console.log("Inside GetTopNews");
newsService.GetNewsList().
then(function(response) {
$scope.$apply(function() {
$scope.news.length > 0 ? $scope.news.length = 0 : null;
response.data.forEach(function(n) {
$scope.news.push(n)
});
console.log("VM", vm);
})
}, function() {
alert("COULD NOT RETRIEVE NEWS LIST");
});
};
}
function newsService($timeout) {
return {
GetNewsList: function() {
return new Promise(function(res, rej) {
$timeout(function() {
console.log("Waited 2 seconds: Returning");
res({
data: ["This should do the trick!"]
});
}, 2000);
})
}
}
}
})();

I am using AngularJs to retrieve the data from ASP.Net Controller.
The Json data is retrieved from the server, but can't figure out why cannot display array items when using the ng-repeat:
var app = angular.module('Appp', []);
app.controller('metadataCtrl', function ($scope, $http) {
$scope.lookupItems = {};
$http({ method: 'GET', url: '/home/listvalues?listid=3' }).then(function (response) {
$scope.lookupItems = response;
console.log($scope.lookupItems);
},
function (error) { alert("error"); });
// console.log($scope.listItems);
});
<form name="myForm" ng-controller="metadataCtrl" class="my-form">
<div ng-repeat="item in lookupItems">
{{$index}}
{{item.ListValueID}}
</div>
</form>
The Json Retrieved from the server:
[{"ListValueID":13,"Translation":{"TranslationID":0,"Value":"Important","LanguageValues":{"ar":"مهم","en":"Important"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0},
{"ListValueID":14,"Translation":{"TranslationID":0,"Value":"Less Importance","LanguageValues":{"ar":"أقل أهمية","en":"Less Importance"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0},
{"ListValueID":15,"Translation":{"TranslationID":0,"Value":"Very Important","LanguageValues":{"ar":"كثير الأهمية","en":"Very Important"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0}]
The most likely issue (assuming that your app and controller are constructed and referenced properly) is that the object returned from the promise contains a .data property which actually holds your JSON data.
Try this:
$http({ method: 'GET', url: '/home/listvalues?listid=3' })
.then(function (response) {
$scope.lookupItems = response.data;
console.log($scope.lookupItems);
},
function (error) {
alert("error");
});
I think you just forgot to wrap your app with ng-app:
var app = angular.module('Appp', []);
app.controller('metadataCtrl', function ($scope, $http) {
$scope.lookupItems = {};
$scope.lookupItems = [{"ListValueID":13,"Translation":{"TranslationID":0,"Value":"Important","LanguageValues":{"ar":"مهم","en":"Important"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0},
{"ListValueID":14,"Translation":{"TranslationID":0,"Value":"Less Importance","LanguageValues":{"ar":"أقل أهمية","en":"Less Importance"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0},
{"ListValueID":15,"Translation":{"TranslationID":0,"Value":"Very Important","LanguageValues":{"ar":"كثير الأهمية","en":"Very Important"}},"ListCategory":{"ListID":4,"Translation":{"TranslationID":0,"Value":"","LanguageValues":{"ar":"","en":""}}},"Parent":0}];
console.log($scope.lookupItems);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="Appp">
<form name="myForm" ng-controller="metadataCtrl" class="my-form">
<div ng-repeat="item in lookupItems">
{{$index}}
{{item.ListValueID}}
</div>
</form>
</body>
You probably misspelled Appp. Make sure your module definition in your javascript:
var app = angular.module('App', []); //Changed to App from Appp
matches your app declaration in your html
<div ng-app="App">
...controller declaration...
...body.....
</div>
I'm using Angular Material md-autocomplete in my project. In that I'm getting the suggest listing from the Service Host via ajax call using $http service.
Issue: $http issue - Values can't be returned before a promise is
resolved in md-autocomplete Angular Material
My Requirement: I need an updated Suggestion List using remote data
sources in md-autocomplete Angular Material - Ajax $http service.
I used the approach as mentioned in Angular Material link https://material.angularjs.org/latest/demo/autocomplete
Source Code:
Scenario 1:
HTML Source Code:
<md-autocomplete flex required
md-input-name="autocompleteField"
md-no-cache="true"
md-input-minlength="3"
md-input-maxlength="18"
md-selected-item="SelectedItem"
md-search-text="searchText"
md-items="item in querySearch(searchText)"
md-item-text="item.country" Placeholder="Enter ID" style="height:38px !important;">
<md-item-template>
<span class="item-title">
<span md-highlight-text="searchText" md-highlight-flags="^i"> {{item.country}} </span>
</md-item-template>
</md-autocomplete>
AngularJS Script:
//bind the autocomplete list when text change
function querySearch(query) {
var results = [];
$scope.searchText = $scope.searchText.trim();
if (query.length >=3) {
results = LoadAutocomplete(query);
}
return results;
}
//load the list from the service call
function LoadAutocomplete(id) {
var countryList = [];
$http({
method: "post",
url: "https://www.bbminfo.com/sample.php",
params: {
token: id
}
})
.success(function (response) {
countryList = response.records;
});
return countryList;
}
Scenario 2:
HTML with AngularJS Source Code:
<!DOCTYPE html>
<html>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/angular_material/1.0.0/angular-material.min.css">

No Person matching "{{searchText}}" were found.
</md-not-found>
</md-autocomplete>
<br/>
</div>
<script>
var app = angular.module('myApp', ['ngMaterial']);
app.controller('myCtrl', function ($scope, $http, $q) {
$scope.searchText = "";
$scope.Person = [];
$scope.selectedItem = [];
$scope.isDisabled = false;
$scope.noCache = false;
$scope.selectedItemChange = function (item) {
alert("Item Changed");
}
$scope.searchTextChange = function () {
$http({
method: "POST",
url: "https://www.bbminfo.com/sample.php",
params: {
token: $scope.searchText
}
})
.success(function (response) {
$scope.Person = response.records;
});
}
});
</script>
</body>
</html>
In Scenario 1, I used the function to fetch the filtered list md-items="item in querySearch(searchText)". But in Scenario 2, I used a $scope variable md-items="item in Person"
Kindly refer the Snapshots
Snapshot 1:
Here I'm searching for indian but it shows the result for india. I debugged the issue in Firefox Browser Firebug, see the above Snapshot 1 it shows, the request was sent for the search term indian via POST Method and I got the response of one matching items as a JSON Object successfully, which is shown in the bottom of SnapShot 1
The issue I find out in this case, the Values can't be returned before
a promise is resolved
Steps I tried:
Case 1: I used the AngularJS filter in UI md-items="item in Person | filter: searchText", it gives the filtered list of previously fetched remote data not a currently fetched remote data. While on Backspacing the character in the textbox it shows the improper suggestion list.
Case 2: I tried to update the changes in UI by calling $scope.$apply() within a $http service, but it fails. Because $http service calling the $scope.$apply() by default, show it throws me an error Error: [$rootScope:inprog].... Finally in this attempt I failed.
Case 3: I created a function, within the function I'm manually called the $scope.$apply(), within the function I manually pushed and poped one dummy item to the $scope variable which is bind in the md-autocomplete. But I failed in this attempt. Because here also I got a same output as same as in the snapshot.
function Ctrlm($scope) {
$scope.messageToUser = "You are done!";
setTimeout(function () {
$scope.$apply(function () {
$scope.dummyCntry = [
{
sno: 0,
country: ""
},
];
$scope.Person.push($scope.dummyCntry);
var index = $scope.Person.indexOf($scope.dummyCntry);
$scope.Person.splice(index, 1);
});
}, 10);
}
Case 4: I did the same approach as like "Case 3" within the $scope.$watchCollection. Here also I got a setback.
$scope.$watchCollection('Person', function (newData, oldDaata) {
$scope.dummyCntry = [
{
sno: 0,
country: ""
},
];
newData.push($scope.dummyCntry);
var index = newData.indexOf($scope.dummyCntry);
newData.splice(index, 1);
});
Case 5: Instead of $http service, I used the jquery ajax call. In that I used the $scope.apply() to update the UI manually. I failed in this attempt once again, here also I got the same output.
$scope.searchTextChange = function () {
if (($scope.searchText != undefined) && ($scope.searchText != null)) {
$.ajax({
type: 'GET',
url: "https://www.bbminfo.com/sample.php?token=" + $scope.searchText,
success: function (response) {
$scope.$apply(function () {
$scope.Person = response.records;
});
},
error: function (data) {
$scope.$apply(function () {
$scope.Person = [];
});
},
async: true
});
} else {
$scope.Person = [];
}
}
In all the attempts I can't able to fix the issue.

I Briefly explained about md-autocomplete in the following blog - http://www.increvcorp.com/usage-of-md-autocomplete-in-angular-material/
I struggled with this as well for a bit. Basically you should actually be returning a promise that returns the content.
This is my "search" function
$scope.searchData = function (searchTxt) {
return $http.get('/TestSearch', { params: { searchStr: searchTxt } })
.then(function(response) {
return response.data;
});
};
Also I'm not sure what version of angular you're running but I think .success was deprecated.
And here is my md-autocomplete as well
<md-autocomplete placeholder="Text goes here"
md-selected-item="vm.autocomp"
md-search-text="searchText"
md-items="item in searchData(searchText)"
md-item-text="item">
<span md-highlight-text="searchText">{{item}}</span>
</md-autocomplete>
EDIT1:
Sorry original JS was in TypeScript. Fixing that now
The Answer Marked is Correct.
.then() - full power of the promise API but slightly more verbose
.success() - doesn't return a promise but offers slightly more convenient syntax
Why not just put return countryList inside the success function.
function LoadAutocomplete(id) {
var countryList = [];
$http({
method: "post",
url: "https://www.bbminfo.com/sample.php",
params: {
token: id
}
})
.success(function (response) {
countryList = response.records;
return countryList;
})
.error(function (response) {
countryList = [];
return countryList;
});
}
edit due to deprecation of .success and .error methods:
function LoadAutocomplete(id) {
var countryList = [];
$http({
method: "post",
url: "https://www.bbminfo.com/sample.php",
params: {
token: id
}
})
.then(function (response) {
countryList = response.data.records;
return countryList;
},function () {
countryList = [];
return countryList;
});
}
Here is my angular code:
'use strict';
var app=angular.module('app',['ngRoute','appFactories']);
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/admin', {
templateUrl: '/pages/admin/allcards.html',
controller: 'MainController'
})}]);
var factories=angular.module('appFactories',['ngResource']);
factories
.factory('CardFactory',['$resource',
function($resource) {
return{
all: $resource('/worldonlinenew/card/common', {}, {query: {method: 'GET', params: {id: '#id'}}}),
}
}])
.factory('StaticFactory',['$resource',
function($resource) {
return{
languages: $resource('/worldonlinenew/static/languages', {}, {query: {method: 'GET',isArray: true}}),
}
}]);
app.controller('CardController',function CardController($scope, CardFactory, StaticFactory){
$scope.card=null;
$scope.languages=null;
$scope.translate=function(language, text){
for(var i=0;i<text.translatedTexts.length;i++){
if(text.translatedTexts[i].language==language){
return translate;
}
}
}
$scope.initCard = function(id){
$scope.card=CardFactory.all.query({id: id});
$scope.languages=StaticFactory.languages.query({id: id});
}
});
And here is my template, where i'm trying to call this function:
</head>
<body ng-controller="CardController" >
<div class="container">
<div th:attr="ng-init='initCard(\''+${id}+'\');'"></div>
<h4 sec:authentication="name"></h4>
<div class="row-fluid">
<h1>Card ID: {{card.id}}</h1>
<!-- Next two strings works fine -->
<h1>name one: {{card.name.translatedTexts[0].content}}</h1>
<h1>name two: {{card.name.translatedTexts[1].content}}</h1>
<div ng-repeat="language in languages" ng->
<h1 ng-bind="translate(language,card.name)"></h1>
</div>
</div>
</div>
</body>
</html>
My browser's console print something like "can't get translatedTexts of undifined, i.e. text parameter is undifined. But language parameter is ok, because it's declared in ng-repeat.
Ok, working sample code here. If card.name always undefined it means when iterator working but var not ready on not in same scope in same time. See sample and check your code.
[Update]
Yes. Problem in initCard function. This function 'sync' but $resource native async (CardFactory.all.query,StaticFactory.languages.query). And you must wait when function resolve.
Example:
app.controller('CardController',function($scope,CardFactory){
init();
/////////
function init(){
CardFactory.all.query({id:1})
.$promise
.then(function(result){
// ready
});
// or
CardFactory.all.query({id:1}, function(cards){
// ... if
$scope.cards = cards;
});
}
})
working code here
angular $resource docs
Finally, here is the answer! As i've wrote, ng-bind=translate(language,card.name) executes before init function, and as we can see, in my model $scope.card=null;. So, field card.name not only empty, this field doesn't exists.
Solution:
function Card(){
this.id=new Number();
this.name=new Text();
}
function Text(){
this.id=new Number();
this.name=new String();
this.translatedTexts=new Array();
}
$scope.card=new Card();
