displaying data ng-repeat from $scope.items query not working

I do not know what is wrong, ng-repeat is not
populating the information on my div, please look at the following
and advice where I have gone wrong
app.js
var mainApp = angular.module('mainApp', ["ngRoute", "ngResource"]);
mainApp.factory('EventListFactory',['$resource', EventListFactory]);
mainApp.controller('EventListCtrl', ['$scope','EventListFactory', EventListCtrl]);
var configFunction = function ($routeProvider) {
$routeProvider.
when('/Register', {
templateUrl: 'routesDemo/Register'
})
.when('/UpdateProfile', {
templateUrl: 'routesDemo/UpdateProfile'
})
.when('/Events', {
templateUrl: 'routesDemo/Events',
controller: EventListCtrl,
})
.when('/routeThree', {
templateUrl: 'routesDemo/three'
});
}
configFunction.$inject = ['$routeProvider'];
mainApp.config(configFunction);
EventListFactory.js
var EventListFactory = function ($resource, $location) {
var baseUrl = "";
if (window.location.hostname == 'localhost') {
baseUrl = "http://localhost:52182/api/Events/GetEvents/";
}
else
{
var deployAt = window.location.href.substring(0, window.location.href);
baseUrl = deployAt + "/api/Events/GetEvents";
}
var respone = $resource(baseUrl, null, { query: { method: 'GET', isArray: true, url: baseUrl }, get: { method: 'GET', url: baseUrl } });
console.log("api json at :" + baseUrl);
var records = respone.query();
console.log(records);
return records;
}
EventListController.js
var EventListCtrl = function ($scope, EventListFactory) {
$scope.Message = 'I work';
$scope.items = EventListFactory;
};
EventListCtrl.$inject = ['$scope'];
in the html:
<div id="listView" >
<h1 class="form-signin-heading">For real {{Message}}</h1>
<div ng-controller="EventListCtrl">
<p class="form-signin-heading">Populated Data</p>
<div ng-repeat="item in items ">
<span class="control-label">Heading : </span> {{item.Heading}}
<br/>
<span class="control-label">Event Date : </span> {{item.EventDate}}
<br/>
</div>
</div>
</div>
running the site:
api call from browser:

the code for ng-repeat is correct, but your items is an empty array so nothing gets displayed.
From the screenshots it appears that records in EventListFactory.js does not return an array but a promise.
In EventListController.js instead of
$scope.items = EventListFactory;
Try something like:
var promise = EventListFactory;
promise.then(function(data){
$scope.items = data;
})

Angular form submission not displaying results from PHP

I'm trying to display the results from a submitted form, AngularJS > PHP > Back but I'm getting nothing. I've tried a lot of different ways and according to all of google I'm doing it right but the console log just says that it's undefined.
Here is the submit function:
$scope.testProcessForm = function() {
$http({
method : 'POST',
url : 'test.php',
data : $scope.formData,
headers : {'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8'}
})
.success(function(data) {
if (data.errors) {
// Showing errors.
$scope.errorselectedServices = data.errors.selectedservices;
$scope.errorincEmail = data.errors.incemail;
} else {
$scope.submissionMessage = data.messageSuccess;
$scope.test= data.test;
The PHP:
$data['test'] = $test;
echo json_encode($data);
HTML:
<div ng-show="test">{{test}}</div>
Why am I getting "test is undefined" and no div? If I put an echo into PHP I get the proper reply back. It doesn't appear to hang anywhere in the code after some debugging. What am I doing wrong?

I found the error. Apparently you have to quote the variable into the array;
$data['faxSender'] = "$faxSenderPhoneNo";
Now works as intended.
EDIT:
Well it worked to a point. My divs still weren't displaying. After logging with console.log(data) I could see that I had a lot of undefined indexes but my data array was there so I didn't understand why I couldn't access it.
I fixed the undefined stuff and then suddenly every div was displayed. Not a clue why PHP decides to dump all that info into my $data array.
2nd edit: Apparently .success is deprecated. Using .then instead with error_reporting(1); seems to always give me an array with data that angular then can use.

Since you are JSON encoding data in php file, file returning a String. so, you will need decode JSON to Java script object first. Also, you $http returns angular promise($q service). I am not sure about using
.success
method. Instead use
.then
.then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
// decode JSON firs since you are sending JSON from PHP
var data = JSON.parse(response);
$scope.test = data.test;
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
// Handle error here
});

Delay directive/div until scope value available

I have a custom directive for soundcloud that requires the soundcloud url. The soundcloud url is fetched from the database through the $http service, however, the div for the soundcloud custom directive is loaded and requires the value of the soundcloud url before it is even defined.
The Plangular Directive Code I got is here:
https://github.com/jxnblk/plangular/blob/master/src/plangular.js *I did not develop this
This is my HTML code:
<div plangular="{{soundcloud}}">
<button ng-click="playPause()">Play/Pause</button>
<progress ng-value="currentTime / duration || 0">
{{ currentTime / duration || 0 }}
</progress>
</div>
And this is the Angular Code:
displaySong.controller('song', ['$scope', '$http', 'fetchSong', function($scope, $http, fetchSong) {
$scope.songID
$scope.songName;
//Controller properties
$scope.songPromise; //The song promise for fetching
$scope.init = function(songID, userID) {
$scope.songID = songID;
$scope.userID = userID;
$scope.songPromise = $http({
method: "post",
url: fetchSong,
data: {
song_id: $scope.songID
},
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(function(successResponse) {
console.log('Successfully fetched song');
console.log(successResponse);
var song = successResponse.data;
$scope.songID = song.song_id;
$scope.songName = song.song_name;
$scope.songType = song.song_type;
$scope.songEmbed = song.song_embed;
$scope.soundcloud = song.song_embed;
}, function(errorResponse) {
console.log('Error fetching');
$scope.songID = null;
});
};
}]);
I know it's a problem with the asynchronous nature because when I add this line in the beginning of my song controller:
$scope.soundcloud = "https://soundcloud.com/jshigley/shine";
It works perfectly fine. I've also noticed that when I spam the play/pause button that DOES come up from the directive, I get multiple console errors of "HTTP 404 Not Found", which leads me to believe it's trying to find a track of undefined url
Since it's a div directive and not a function call I can't use promises such as chaining a then to my $scope.songPromise. I've thought of putting it into a controller and having the controller do something like $timeout for 5 seconds, but I don't think this delays the execution of the DOM.
The soundcloud URL DOES end up getting loaded, but it remains undefined in the eyes of the plangular directive (I've actually encountered lots of these problems with bad timing of loading scope and directives). Any Angular Wizards willing to teach me how to tame the asynchronous nature of AngularJS?

You can use $watch in the custom directive to watch when url attributes is changed.
In
link: function(scope, el, attr) {
change from
if (src) {
resolve({ url: src, client_id: client_id }, function(err, res) {
if (err) { console.error(err); }
scope.$apply(function() {
scope.track = createSrc(res);
if (Array.isArray(res)) {
scope.tracks = res.map(function(track) {
return createSrc(track);
});
} else if (res.tracks) {
scope.playlist = res;
scope.tracks = res.tracks.map(function(track) {
return createSrc(track);
});
}
});
});
}
to
scope.$watch('attr.plangular', function(newVal) {
resolve({ url: attr.plangular, client_id: client_id }, function(err, res) {
if (err) { console.error(err); }
scope.$apply(function() {
scope.track = createSrc(res);
if (Array.isArray(res)) {
scope.tracks = res.map(function(track) {
return createSrc(track);
});
} else if (res.tracks) {
scope.playlist = res;
scope.tracks = res.tracks.map(function(track) {
return createSrc(track);
});
}
});
});
}, true);
If you dont want to change the directive then you might want to use ng-if to load that plangular div only when you get the url.
<div plangular="{{soundcloud}}" ng-if="haveurl">
and in the angular code :
}).then(function(successResponse) {
console.log('Successfully fetched song');
console.log(successResponse);
$scope.haveurl = true;

Try using ng-show like this to only show the div once your $http request has been completed.
<div ng-show="httpRequestComplete" plangular="{{soundcloud}}">
<button ng-click="playPause()">Play/Pause</button>
<progress ng-value="currentTime / duration || 0">
{{ currentTime / duration || 0 }}
</progress>
</div>
displaySong.controller('song', ['$scope', '$q', '$http', 'fetchSong', function($scope, $http, fetchSong) {
/* add $q promise library */
$scope.songID
$scope.songName;
var httpRequest = function() {
var deferred = $q.defer();
$http({
method: "post",
url: fetchSong,
data: {
song_id: $scope.songID
},
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).success(function(successResponse) {
deferred.resolve({response: successResponse});
console.log('Successfully fetched song', successResponse);
var song = successResponse.data;
$scope.songID = song.song_id;
$scope.songName = song.song_name;
$scope.songType = song.song_type;
$scope.songEmbed = song.song_embed;
$scope.soundcloud = song.song_embed;
}).error(function(error) {
console.log(error);
});
return deferred.promise;
};
httpRequest().then(function(response) {
$scope.httpRequestComplete = true;
console.log('div will show');
};
}]);
I would do something like this that delays the showing of the div until httpRequestComplete = true, or until your promise ($q) is fulfilled. This will make sure that your div isn't loaded until you have the information available.

Revealing module for AJAX Angular Service

Below I've got an angular app and controller where the controller have data access inside of it (bad idea, I know)
var app = angular.module('app',[]);
app.controller('HomeController',function($scope,$http){
$scope.people = null;
$scope.get = function() {
$http({
url: 'largeTestData.json',
method: 'GET'
}).then(function(data){
console.log('request successful, here is your data: ');
console.log(data['data']);
$scope.people = data['data'];
},function(reason){
console.log('this failed, this is the reason: ');
console.log(reason);
})
}
});
app.controller('ControllerWithService',function($scope, MyService){
$scope.get = MyService.get;
$scope.get(function(data){
console.log('you succeeded');
},function(reason){
console.log('you failed');
console.log(reason);
})
})
This will work in retrieving data and putting it onto the page. Knowing that having data Access in the controller is no bueno I tried to abstract that out into a service:
app.service('MyService',function($http,$q){
var get = function(){
var deferred = $q.defer();
var url = 'test.json';
$http.get(url).success(deferred.resolve).error(deferred.reject);
}
return {
get: get
}
})
Here my 'data layer' is a service that only has one method: get from the above listed URL.
app.service('MyService',function($http,$q){
var get = function(){
var deferred = $q.defer();
var url = 'test.json';
$http.get(url).success(deferred.resolve).error(deferred.reject);
}
return {
get: get
}
})
and my HTML
<body>
<script src="libs/angular-1.2.15.js"></script>
<script src="app/app.js"></script>
<script src="app/DocumentService.js"></script>
<script src="libs/jQuery-2.1.1.js"></script>
<div ng-controller="HomeController">
<button ng-click="get()" href="#">Get data</button>
<div>{{message}}</div>
<!--<div ng-repeat="p in people" >-->
<!--<b>Business Doc ID: </b><h1>{{p['busDocId']}}</h1>-->
<!--<b>DOC ID: </b>{{p['docId']}}-->
<!--<b>FILE NAME: </b><div style="color: green">{{p['fileName']}}</div>-->
<!--</div>-->
</div>
<div ng-controller="ControllerWithService">
{{message}}
<button ng-click="get()">get data</button>
<div>{{data}}</div>
</div>
</body>
I'm not getting any error messages, and the commented out out stuff in my HomeController works as expected. What am I doing wrong in trying to make my AJAX calls a service?
working solution changes:
app.service('MyService',function($http,$q){
this.get = function(){
return $http.get('test.json')
}
})
app.controller('ControllerWithService',function($scope, MyService){
$scope.data = null;
$scope.get = function() {
MyService.get().then(function (data) {
console.log('this is the success data: ');
console.log(data)
$scope.data = data;
}, function (reason) {
console.log('this is the fail reason');
console.log(reason);
$scope.data = reason;
})
}
})

It looks like it could be a couple different things. I'll post an example I have working in one of my projects right now. It should be extremely similar and simple with what you're goal is.
Service:
'use strict';
angular.module('srcApp')
.service('Getlanguage', function Getlanguage($location, $http, $log, $state, $rootScope) {
this.getContent = function() {
var language = $location.path().split('/'),
languageCulture = language[1];
if (!languageCulture) {
languageCulture = 'en';
}
$rootScope.cultureCode = languageCulture;
return $http({method: 'GET', url: '/languages/' + languageCulture + '.json'})
.error(function() {
// If service cannot find language json file, redirect to index
$state.go('lang', {lang: 'en'});
});
};
});
Controller Call to service:
After passing in the service as a dependency into the controller.
Getlanguage.getContent().then(function(res) {
$scope.content = res.data;
});
Hope this helps.

Angular ui grid how to show a loader

I'm wondering how to show a simple loader before data was loaded.
I'm using ng-grid-1.3.2
I'm googling but I didn't find any example.
Bye

like Maxim Shoustin suggested you can use the angularjs-spinner from Jim Lavin which uses (deprecated) Response Interceptors.
I think it's explained best here :
http://codingsmackdown.tv/blog/2013/04/20/using-response-interceptors-to-show-and-hide-a-loading-widget-redux/
In a nutshell, in his first solution, what you have to do for your ng-grid app is:
1) Add the loading gif to your html (for loading gif look here)
<div id="loadingWidget" class="row-fluid ui-corner-all" style="padding: 0 .7em;" loading-widget >
<div class="loadingContent">
<p>
<img alt="Loading Content" src="images/ajax-loader.gif" /> Loading
</p>
</div>
</div>
2) In your code as soon as you have declared your app level module add the Response Interceptors for http requests to the configuration block
var app = angular.module('myCoolGridApp', ['ngGrid']);
app.constant('_START_REQUEST_', '_START_REQUEST_');
app.constant('_END_REQUEST_', '_END_REQUEST_');
app.config(['$httpProvider', '_START_REQUEST_', '_END_REQUEST_', function ($httpProvider, _START_REQUEST_, _END_REQUEST_) {
var $http,
interceptor = /* see extra details on codingsmackdown.tv */
$httpProvider.responseInterceptors.push(interceptor);
}
3) and then add your loadingWidget directive
app.directive('loadingWidget', ['_START_REQUEST_', '_END_REQUEST_', function (_START_REQUEST_, _END_REQUEST_) {
return {
restrict: "A",
link: function (scope, element) {
element.hide();
scope.$on(_START_REQUEST_, function () {element.show();});
scope.$on(_END_REQUEST_, function () {element.hide();});
}
};
}]);
See more details at codingsmackdown

I had the same question as you.
I find this nice tutorial about it: http://brianhann.com/ui-grid-the-easiest-customization-youll-ever-write/
He use vm.loading = true while fetching data from server and changed to false after complete.
var app = angular.module('app', ['ngTouch', 'ui.grid']);
app.controller('MainCtrl', ['$http', '$timeout', function ($http, $timeout) {
var vm = this;
vm.reset = reset;
vm.noData = noData;
vm.gridOptions = {
columnDefs: [
{ field: 'name' },
{ field: 'age' }
]
};
reset();
////////////
// Initialize our data source
function init() {
$http.get('data.json')
.success(function (data) {
vm.gridOptions.data = data;
})
.finally(function () {
vm.loading = false;
});
}
// Reset the data source in a timeout so we can see the loading message
function reset() {
vm.loading = true;
vm.gridOptions.data = [];
$timeout(function () {
init();
}, 1000);
}
function noData() {
vm.gridOptions.data = [];
}
}]);
In the HTML, he uses ng-hide to show/hide the spinner based on values of gridOptions.data and vm.loading:
<div id="grid1" ui-grid="vm.gridOptions" class="grid">
<div class="grid-msg-overlay" ng-hide="!vm.loading">
<div class="msg">
<span>
Loading Data...
<i class="fa fa-spinner fa-spin"></i>
</span>
</div>
</div>
<div class="grid-msg-overlay" ng-hide="vm.loading || vm.gridOptions.data.length">
<div class="msg">
<span>No Data</span>
</div>
</div>
</div>
Here is the Plunker of the final version shown.

You have angularjs-spinner, see GitHub sources

I also needed a similar behavior and I came across this answer but I needed to show something inside the grid itself so here is something I put together. My idea is that I change the gridOptions on the fly and show a loader as a row inside the grid.
loaderOptions = {
"columnDefs": [{
"name": "",
"field": "loading",
"enableColumnMenu": false,
"cellTemplate": '<div style="width:90px; margin:auto;"><span class="glyphicon glyphicon-refresh glyphicon-refresh-animate"></span> Loading...</div>'
}],
"data": [{
"loading": ""
}]
};

Simply,by adding this code in your html part:
<img alt="loading..." src='images/ajax-loader.gif")' /> loading message...
and the following code in your app.controller script:
$http.get(yourdataUrl)
.then(function (response) {
$scope.records = response.data;
$("#loadingWidget").hide();
});
it works fine for me!

The HTML code-sample
<img ng-show="loading" src="~/img/loding.jpg" />
<div class="ngtyle" ng-grid="myGridView"></div>
The AngularJs code-sample
var app = angular.module('App', ['ngGrid']);
app.controller('MainCtrl', function ( $scope, myService ) {
$scope.loading = true;
myService.get().then( function ( response ) {
$scope.items = response.data;
})
.finally(function() {
$scope.loading = false;
});
$scope.myGridView = {
data: 'dataList',
columnDefs: 'myDisplayColumns'};
});
