I've just learned AngularJs. I've try to show a data from controller. but the data not show.
my view :
<!DOCTYPE html>
<html>
<head>
<title>Belajar AngularJs</title>
</head>
<body ng-app="FirstApp">
<div ng-controller="MainController">
{{title}} </br>
{{book.title}} </br>
{{book.author}} </br>
{{book.price}}
</div>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.6/angular.min.js"></script>
<script src="js/app.js"></script>
<script src="controllers/MainController.js"></script>
<script type="text/javascript"></script>
</body>
</html>
my controller :
app controller('MainController',['$scope', function ($scope) {
// body...
$scope.title='Belajar AngularJs';
$scope.book={
title: 'Belajar Angularjs Bersama Ciwuk',
author : 'Ciwuk';
price : 'Free'
};
}]);
my model :
var app=angular.module('FirstApp',[]);
the result was like this :
error
anyone help me please? i'm new in angularJS
You should use app.controller and author : 'Ciwuk',. Use comma not semicolon.
Try use console(F12) when error happen.
#DieuNQ pointed correct to your typo. But here is even better way:
(function () {
"use strict";
angular.module('your_module_name', []).controller("MainController", [

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".
Here is JSBin with working example: http://jsbin.com/ficozajena/1/edit?html,js,output
I'm copying my code exactly from an egghead.io tutorial but it isn't working. The angular expression isn't posting to the view properly (it posts with the {{}} rather than evaluating). It works if I remove ng-controller from the <body> and the value "app" from ng-app in the <html> so I can't figure out where to pinpont the problem. I've tried moving the script for the angular module/controller all over the html page (header, bottom of page, etc.) and no luck.
As a side question I'm wondering if Stackoverflow is the proper place to post this. Supposedly you're not supposed to use the 'code-review' tag and reviews of "other-wise working code" belongs on codereview.stack. My code is working sooo...
<!DOCTYPE html>

.controller(FirstCtrl, function FirstCtrl()[
var first = this;
first.greeting = "First";
])

<body ng-controller="FirstCtrl as first">
<input type="text" ng-model="first.greeting"/>
<div ng-class="first.greeting">

I made a slight change to your code.
The Controller name needed double qoutes around it see "FirstCtrl" also you had a missing square bracket and closing bracket. Copy and past the above code it should work.
It works for me. :)
Your copying went wrong somewhere , controller name should be a string
Change:
.controller(FirstCtrl...
to
.controller('FirstCtrl'...
You should have seen errors thrown in console to give you clues about this
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>
Edited: Now this example fully works with external json service to see it in live
I can see the received array and params in the console.log, but I can't echo that array to the view...
That online JSON service returns {"key": "value"}
How to make this {{some_item.key}} to work? Thanks!!
<!DOCTYPE html>
<html ng-app="Simple">
<body>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular-resource.min.js"></script>
<div ng-controller="SimpleController">
{{some_item.key}}
</div>
<script>
angular.module('Simple', ['ngResource']);
function SimpleController($scope, $resource) {
$scope.simple = $resource('http://echo.jsontest.com/key/value',
{callback:'JSON_CALLBACK'},
{get:{method:'JSONP'}}
);
$scope.some_item = $scope.simple.get();
console.log($scope.some_item.key);
}
</script>
</body>
</html>
You need to put the interpolation inside the controller's scope like this
<div ng-controller="SimpleController">
{{some_item.key}}
</div>
I am currently ramping up with angular, and trying to make dynamic routing work.
Note: I have looked at the question: How to defer routes definition in Angular.js?, and I believe I am doing everything it states, but I'm still getting the error "unknown provider: $routeProvider"
What am I doing wrong?
html:
<!doctype html>
<html ng-app="rProvider">
<head>
<link rel="stylesheet" href="css/style.css">
<script src="lib/angular/angular.js"></script>
<script src="js/routeProviderTest.js"> </script>
</head>
<body>
<div ng-controller="rControl">
<h2>Route Controller Test</h2>
[Route 1 | <a>Route 2</a>]
<hr/>
<span class="partial-info">
Partial: {{routeValue}}
</span>
<div ng-view></div>
<small>The Bottom</small>
</div>
</body>
</html>
js:
var myAppModule = angular.module('rProvider',[]);
myAppModule.config(function($routeProvider){
$routeProvider.when("r1",{templateUrl:"/route1.html"});
});
myAppModule.controller('rControl', function($scope, $route){
$scope.routeValue = 'nothing yet';
});
thanks in advance...
If you are using version 1.2.x, you need to download angular-route.js, include it via the <script> tag, and add it as a dependency module in JavaScript:
<!-- in HTML -->
<script src='angular-route.js'></script>
// in JavaScript
var myAppModule = angular.module('rProvider', ['ngRoute']);
Maybe this will help you:

This guy has some pretty good tutorials on AngularJS. Or some of the next videos about the routeProvider.
