I believe I have set everything for Angular to work in Phonegap, but apparently the deviceready function is not having the behavior that I expect.
So here is how I set:
index.html
<html ng-app="app">
<head>
<script type="text/javascript" src="js/lib/angular.min.js"></script>
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/lib/ready.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</head>
<body>
<div class="header" ng-controller="HeaderController">
<h3 id="logo"><img src="img/logo.png"/></h3>
<p>{{title}}</p>
<button ng-click="changeTitle()"></button>
</div>
</body>
</html>
app.js
$app = angular.module('app', ['fsCordova']);
$app.config(function($compileProvider){
$compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel):/);
});
$app.controller('HeaderController', function($scope, CordovaService) {
CordovaService.ready.then(function() {
console.log("Setting the title");
$scope.title = "This title";
$scope.changeTitle = function() {
console.log("Changing the title");
$scope.title = "Title changed";
}
});
});
ready.js from: http://www.ng-newsletter.com/posts/angular-on-mobile.html#native
angular.module('fsCordova', [])
.service('CordovaService', ['$document', '$q',
function($document, $q) {
var d = $q.defer(),
resolved = false;
var self = this;
this.ready = d.promise;
document.addEventListener('deviceready', function() {
resolved = true;
d.resolve(window.cordova);
});
// Check to make sure we didn't miss the
// event (just in case)
setTimeout(function() {
if (!resolved) {
if (window.cordova) d.resolve(window.cordova);
}
}, 3000);
}]);
The title is appearing the way it is {{title}}, not its value. When I click the button, nothing happens, not even the debug logs on the console. Any tips how to set Angular on Phonegap? Thanks.
Apparently on angular 1.2 the urlSanitizationWhitelist doesn't exist anymore.
So I just had to remove the $compileProvider.urlSanitizationWhitelist(/^\s*(https?|ftp|mailto|file|tel):/); line and it worked

In the below code, console.log($scope.gradeC.title); shows the correct output; however the next console line does not show the expected output. I do not understand this behaviour. Any suggestions/pointers would help me to understand this.
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<script>
var myApp=angular.module("myApp", []);
myApp.controller('myCtrl', function($scope, $filter)
{
console.log("Inside controller");
$scope.results = {
year:2013,
subjects:[
{title:'English',grade:'A'},
{title:'Maths',grade:'A'},
{title:'Science',grade:'B'},
{title:'Geography',grade:'C'}
]
};
console.log($scope.results);
$scope.gradeC = $filter('filter')($scope.results.subjects, {grade: 'B'})[0];
console.log($scope.gradeC.title);
console.log(($scope.results.subjects|{grade: 'B'})[0].title);
});
</script>
</head>
<body ng-app="myApp" ng-controller="myCtrl">
<h4>Printing div</h4>
</body>
</html>
you can't use | in controller to filter arrays.
$scope.gradeC = $filter('filter')($scope.results.subjects, {grade: 'C'})[0];
console.log($scope.gradeC);
or
console.log($filter('filter')($scope.results.subjects, {grade: 'C'})[0].title);
i'm new to angularJs and want to learn more about it, i'm trying to display some users from a fake REST Api, when trying to run my code i got empty page and the console doesn't give me any errors , i don't know where is the error or where i can debug.
app.js
var myApp = angular.module("app", []);
contactsData.service.js look like that :
(function () {
var app = angular.module("app");
app.service("contactDataSvc", function ($http) {
var self = this;
self.getContacts = function () {
var promise1 = $http.get("http://localhost:3000/contacts");
var promise2 = promise1.then(function (response) {
return response.data;
});
return promise2;
}
});
})();
contacts.controller.js
(function () {
var myApp = angular.module("app");
myApp.controller("contactsCtrl", contactsCtrl);
function contactsCtrl(contactDataSvc) {
contactDataSvc.getContacts()
.then(function(data){
this.contacts = data;
});
}
})();
finally my view index.html
<html ng-app="app">
<head>
<title></title>
<script src="angular.js"></script>
<script src="app.js"></script>
<script src="contacts.controller.js"></script>
<script src="contactsData.service.js"></script>

<!--<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>-->
</head>
<body class="container">
<div>
<div ng-controller="contactsCtrl as ctrl">
<div class="raw">
<ul class="list-group">
<li class="li-group-item" ng-repeat="obj in ctrl.contacts">
{{obj.name.title + " " + obj.name.first + " " + obj.name.last}}
</li>
</ul>
</div>
</div>
</div>
</body>
</html>
Small correction required in your contactsCtrl
function contactsCtrl(contactDataSvc) {
var vm = this;
contactDataSvc.getContacts()
.then(function(data){
vm.contacts = data;
});
}
You cannot use this inside the then callback as the scope will be different.
Corrected working example here : http://plnkr.co/edit/LLKJipkBbiZ17QjQpw1X

https://www.w3schools.com/js/js_scope.asp
What is the scope of variables in JavaScript?
1 - Is this url correct? http://localhost:3000/contacts
2 - Open the url on any browser, does it return any response ? JSON?
Please check this first to see if the problem is not on the server side.
Firstly inject $scope in controller because anything/data that we want to access over Html from controller needs to be binded on $scope.
So you controller would look like:
(function () {
var myApp = angular.module("app");
myApp.controller("contactsCtrl", contactsCtrl);
function contactsCtrl($scope,contactDataSvc) {
contactDataSvc.getContacts()
.then(function(data){
$scope.contacts = data;
});
}
})();
Secondly from the service you need to return a promise from it only then you will be able to get the data once the response is back from the API.
So,the updated service code is :
(function () {
var app = angular.module("app");
app.service("contactDataSvc", function ($http,$q) {
var self = this;
var defered = $q.defer();
self.getContacts = function () {
var promise1 = $http.get("http://localhost:3000/contacts");
promise1.then(function (response) {
defered.resolve(response.data);
});
return defered.promise;
}
});
})();
I want to write a script in Ionic to refresh a page every 5 minutes or to call the API every 5 minutes. I have tried to use the $interval function but it didn't work. Can anyone give me ideas on where to and how to start ?
Try this
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script type="text/javascript">
angular.module('myModule', [])
.controller('myCtrl', function ($interval, $window) {
$interval(function () {
// loading page again
// $window.location.reload();
//you can modify it as you needd
console.log('called in 5 seconds for 5 minutes change 5000 to 1000*60*5');
}, 5000);
});
</script>
<body ng-app="myModule" ng-controller="myCtrl">
</body>
</html>
Edited
$interval(function () {
// loading page again
// $window.location.reload();
//you can modify it as you needd
$scope.timer = $scope.timer + 5000;
console.log('called in 5 seconds for 5 minutes change 5000 to 1000*60*5');
}, $scope.timer);
this is what you need:
angular.module('test', [])
.controller('test', function ($interval, $timeout, $window) {
//$timeout( function () {
$interval(function () {
// Refresh page
$window.location.reload();
// Or call api
//$http({
//})
}, 1000*60*5);
//}, 1000);
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="test" ng-controller="test">

Using run syntax, $rootScope.variable is introduced at module(sample) level.
What is the syntax to access $rootScope.variable in MyController?
Inject rootScope in controller like this.
angular.module('sample', []).controller('emp', function($scope, $rootScope) {
};
Aside from your issue I dont know why you are mixing controller code in view.Angular is built on MVVM pattern.So separation of controller and view is recommended.
You could do the following, inject $rootScope into the controller
<script type="text/javascript">
function MyController($rootScope) {
this.Name = "jag";
this.sal = "4500";
}
MyController.prototype.getAnnualSal = function(){
return (this.sal) * 12;
}
var app = angular.module("sample", []).run(function($rootScope) {
$rootScope.variable = 1;
});
MyController.$inject = ['$rootScope'];
app.controller("emp", MyController);

//MODEL CREATION
var person=Backbone.Model.extend(

</script>
</head>

<button onclick="perf()">CLICK</button>

This is a simple code, alert is not invoked in the model when an instance of it is created in the perf() function which is called while clicking the button... Please help
Try to write your code in $(function() {}); block or $(document).ready(function () {}); block.
It should work.
You are missing a script reference to Underscore.js
<script type="text/javascript" src="underscore.js"></script>
Backbone requires it as a dependency.
Download it at http://underscorejs.org/ then put it above your script element for backbone.js and it will work fine.
Here's jsfiddle that included both suggestions by dcarson & Naresh J , http://jsfiddle.net/Rvn2L/1/
$(function () {
var person = Backbone.Model.extend({
initialize: function () {
alert("hello backbone");
}
});
function perf() {
console.log('1');
var val = new person();
}
window.perf = perf;
})
