I am looking at this tutorial. And I have such code:
<!DOCTYPE html>
<html lang="en" ng-app="">
<head>
<meta charset="UTF-8">
<title>SPA book_store</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.8/angular.min.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$http.get("http://localhost:8080/book_store/rest/books_json/get")
.then(function(response) {
$scope.books = response.data;
});
});
</script>
<div ng-app="myApp" ng-controller="myCtrl">
<input id="filter_input" type="text" ng-model="nameText"/>
<ul>
<li ng-repeat="book in books | filter:nameText | orderBy:'name'">
{{book.name}} - {{book.price}}
</li>
</ul>
</div>
</body>
</html>
http://localhost:8080/book_store/rest/books_json/get is returning following json:
[
{
"book_id":1,
"name":"Book1",
"bought":false,
"genre":"MR",
"price":20,
"users":[
],
"author":{
"author_id":1,
"name":"Gogol",
"books":[
]
}
},
//...
]
But I see in a browser networking that request wasn't fire. What have I done wrong?
Remove the ng-app="" from the html tag or provide the module name ng-app="MyApp".
Also remove one of the ng-app directives either from the the body tag or the html tag.
It is good practice to user the ng-app directive on the HTML tag if you are using just one angular app.

I created a basic AngularJS app and it's not displaying the values on the live site declared on the controller.
The live site displays the expressions written on the controller file instead.
ie. - It displays:
{{ title }}
{{ paragraph }}
Instead of:
First Angular Title
First Angular Paragraph
index.html:
<!DOCTYPE html>
<html>
<head>
<title>Angular Application</title>
<script src="js/shared/angular.min.js"></script>
</head>
<body ng-app="mainApp">
<div ng-controller="MainController">
<h1> {{ title }} </h1>
<p> {{ paragraph }}<p>
</div>
<!-- Modules -->
<script src="js/app.js"></script>
<!-- Controllers -->
<script src="js/controllers/MainController.js"></script>
</body>
</html>
MainController.js
app.controller("MainController", ['$scope', function($scope) {
$scope.title = "First Angular Title";
$scope.paragraph = "First Angular Paragraph";
}]);
app.js
var app = angular.module("mainApp", []);
I don't know what I'm doing wrong. I'm completely new to this. I appreciate any help. Thanks for your time.
I have included the angular from cdn and updated the inline script the same working. please verify included files are loading properly.

I created an ng-sortable example in Plunker but it's not working.
Here's the JavaScript:
angular.module('sortableExample', [])
.controller('PresidentsCtrl', ['$scope', function($scope) {
$scope.presidents = [
'George Washington',
'Abraham Lincoln',
'William Jefferson Clinton'
];
$scope.dragControlListeners = {
accept: function(sourceItemHandleScope, destSortableScope) { return true },
itemMoved: function(event) {},
orderChanged: function(event) {}
};
}]);
And the HTML:
<!DOCTYPE html>
<html ng-app="sortableExample">
<head>
<script data-require="angular.js#1.5.6" data-semver="1.5.6" src="https://code.angularjs.org/1.5.6/angular.min.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="https://raw.githubusercontent.com/a5hik/ng-sortable/master/dist/ng-sortable.js"></scr</script>
<link rel="stylesheet" href="https://raw.githubusercontent.com/a5hik/ng-sortable/master/dist/ng-sortable.css">
<script src="script.js"></script>
</head>
<body ng-controller="PresidentsCtrl">
<ul data-as-sortable="dragControlListeners" data-ng-model="presidents">
<li data-ng-repeat="president in presidents" data-as-sortable-item>
<div data-as-sortable-item-handle>{{ president }}</div>
</li>
</ul>
</body>
</html>
The right stuff shows up but it's not interactive like it should be. Any idea why?
You should not include links to github source -)
Since there is no cdn for ng-sortable - just copy it to plunker.
Also you forget to add dependency of ng-app.
angular.module('sortableExample', ['as.sortable'])

I just started AngularJS today; so I'm still very new to it. I have the following code:
<!DOCTYPE html>
<html ng-app>
<head>
<title>My first AngularJs</title>
</head>
</html>
<body data-ng-controller="SimpleController">
<div class="container">
<h3>Looping with the ng-repeat Directive</h3>
<input type="text" ng-model="nameText"/>{{ nameText}}
<ul>
<li data-ng-repeat="cust in customers | filter:nameText | orderBy:'name'">{{ cust.name | uppercase }} - {{ cust.city}}</li>
</ul>
</div>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript">
function SimpleController($scope){
$scope.customers=[
{name:'Frank Ben',city:'Bamenda'},
{name:'Brize Tankanon',city:'Marous'},
{name:'Brendaline M.',city:'Bafoussam'},
{name:'Alexander Bings',city:'Buea'}
];
}
When I run the above code, this is what I get:
when I remove the controller directive from the body tag, I get this:
I don't know where the problem is coming from. I wish to display those names and cities. I will be grateful for your help. Thanks!
Try to register controller in angularjs app using build in dependency injection, in other words:
<script type="text/javascript">
var app = angular.module("app", []);
app.controller('SimpleController', ['$scope', function SimpleController($scope){
$scope.customers=[
{name:'Frank Ben',city:'Bamenda'},
{name:'Brize Tankanon',city:'Marous'},
{name:'Brendaline M.',city:'Bafoussam'},
{name:'Alexander Bings',city:'Buea'}
];
}]);
</script>
then change ng-app to ng-app="app".

How I can to cut special symbols as JS, HTML and safe from XSS atack?
But I need to display HTML inside getAttachmentTemplate
You need to include angular-sanitize.js, you can then load the ngSanitize module
angular.module('app', ['ngSanitize']);
You can then use the $sanitize service to sanitize your HTML snippets, see an example below:
angular.module('expressionsEscaping', ['ngSanitize'])
.controller('ExpressionsEscapingCtrl', function($scope, $sanitize) {
$scope.msg = 'Hello, <b>World</b>!';
$scope.safeMsg = $sanitize($scope.msg);
});

<body ng-app="expressionsEscaping" ng-controller="ExpressionsEscapingCtrl">
<div class="container">

For some reason when I use ng-repeat the $scope variable does not bind its data to the view. It's been driving me insane because I figure out what i'm doing wrong in this case. In the when I console.log the $scope variable, its there but it just refuses to bind to the view when i'm using ng-repeat. In this case the word "movie" in the paragraph tag is repeated 3x but there's not data to go with it. Here is the code below:
<html ng-app="myApp" ng-controller="IndexCtrl">
<head>
<base href="/">
<title>Page Title</title>
</head>
<body>
<div>Hello World!
<div ng-repeat="movie in movies">
<p>movie: {{movie.moviename}}</p>
</div>
</div>
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script type="text/javascript">
var myApp = angular.module("myApp", []);
function IndexCtrl($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
};
</script>
</body>
</html>
After long sleepless nights lol I figured out the answer. Apparently the problem was with my node js express server using mustache as a middleware to template html. It uses the {{ }} symbols as well so angular never got to interpret what was going on. So I used $interpolateProvider to change the angular symbols and now it works beautifully.
var myApp = angular.module('myApp', [], function($interpolateProvider) {
$interpolateProvider.startSymbol('[[');
$interpolateProvider.endSymbol(']]');
});
To anyone else using a node.js backend and not using jade as a template language, I hope this helps!
It would be better to explicitly define the controller inside the module:
var myApp = angular.module("myApp", []);
myApp.controller('IndexCtrl', function($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
});
But.... I copied the code exactly, replaced angular resource path. And all is working.
<html ng-app="myApp" ng-controller="IndexCtrl">
<head>
<base href="/">
<title>Page Title</title>
</head>
<body>
<div>Hello World!
<div ng-repeat="movie in movies">
<p>movie: {{movie.moviename}}</p>
</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module("myApp", []);
function IndexCtrl($scope) {
$scope.movies = [
{'moviename':'ironman'},
{'moviename':'antman'},
{'moviename':'man'}
];
console.log($scope.movies);
};
</script>
</body>
</html>
