I have just gotten started with AngularJS (coming from jQuery) and it seems worthwhile to replace a majority of my jQuery.
I decided that the easiest place to start was all the simple show / hide tabbed content I have. Currently, I have all the applicable html within the page that loads. However, it seems like I'd be better off loading the entirety of these tabbed sections using Angular routes. Am I correct in that assumption? Or should I use some hybrid approach (the content within these sections is dynamic)?
Anyway, with the Angular solution, I cannot seem to get the script to work for routes. I am in very new territory with this and am clueless as to where I am going wrong. Any help is grea
My currently HTML (simplified):
<!DOCTYPE html>
<html data-ng-app='mainApp'>
<head>
<script src='js/jquery.min.js'></script>
<script src='js/angular.min.js'></script>
</head>
<body>
<div class='toggleButtons'>
<a href='#/info'>
<div></div>
</a>
<a href='#/comment'>
<div></div>
</a>
<a href='#/feedback'>
<div></div>
</a>
</div>
<div class='container'>
<div data-ng-view=''></div>
</div>
<script src='app/main.app.js'></script>
</body>
</html>
Angular:
/// <reference path="../js/angular.min.js" />
var mainApp = angular.module('mainApp', []);
mainApp.config(function ($routeProvider) {
$routeProvider
.when('/info',
{
controller: 'mainInfoController',
templateUrl: '/app/partials/info.html'
})
.when('/comment',
{
controller: 'mainCommentController',
templateUrl: '/app/partials/comment.html'
})
.when('/feedback',
{
controller: 'mainFeedbackController',
templateUrl: '/app/partials/feedback.html'
})
.otherwise({ redirectTo: '/app/partials/info.html' });
});
Just to note: the controllers above are just placeholders really. I have not created them yet. However, I don't care if they work or not now. I am just concerned with getting the partial view routes to show up. They aren't though. Clicking the links does properly show page.html#/info (or comment or feedback... etc.). But nothing happens.
Also file path is as follows:
main folder = html
js = scripts
app = angular files (app.js / module files here)
views
partials
controllers
services
What am I doing wrong?
<!DOCTYPE html>
<html ng-app='mainApp'>
<head>
<script src='https://ajax.googleapis.com/ajax/libs/angularjs/1.0.6/angular.min.js'></script>
<script>
var mainApp = angular.module('mainApp', []);
mainApp.config(function($routeProvider) {
$routeProvider
.when('/info', {
controller: 'mainInfoController',
templateUrl: 'app/partials/info.html'
})
.when('/comment', {
controller: 'mainCommentController',
templateUrl: 'app/partials/comment.html'
})
.when('/feedback', {
controller: 'mainFeedbackController',
templateUrl: 'app/partials/feedback.html'
})
.otherwise({
redirectTo: '/info'
});
function mainInfoController($scope) {}
function mainCommentController($scope) {}
function mainFeedbackController($scope) {}
});
</script>
</head>
<body>
<div class='toggleButtons'>
<a href='#/info'>
<div>Info</div>
</a>
<a href='#/comment'>
<div>Comment</div>

I'm starting to configure my application with Angularjs, I am following a route guide but I can not make the project run
i dont know how to register my controllers and services for load
dynamically when i change pages... :/ y created mi appConfig file for configure my routes.
My directory.
my app config:
angular.module('library.crud', ['ngRoute'])
.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'app/views/home.html'
})
.when('/book', {
templateUrl: 'app/views/book.html',
controller: 'bookController',
controllerAs: 'vm'
})
.when('/books', {
templateUrl: '../app/views/books.html',
controller: 'booksController',
controllerAs: 'vm'
})
.otherwise({
redirectTo: '/'
});
});
example controller:
(function () {
'use stritct';
angular
.module('library.crud')
.controller('booksController', booksController);
booksController.inject = ['$rootScope', '$scope', 'bookService'];
function booksController($rootScope, $scope, bookService) {
var vm = this;
}
})();
example service:
(function () {
'use strict';
angular
.module('library.crud', [])
.factory('bookService', bookService);
bookService.$inject = ['$http', '$q'];
function bookService($http, $q) {
var service = {
};
return service;
}
})();
indexHTML:
<html>
<head>
<!--script imports, angular, jquery, bootstrap etc... -->

<li class="active">Home</li>
<li>Home</li>
<li>Books</li>
<div class="container">
<div ng-view></div>
</div>
</body>
</html>
at what time do my HTML pages know which controller to invoke and where is it located? how register my services ?
When i enter a books options from menu, the console show the next error:
The controller with the name 'booksController' is not registered.

There are two things in your code,
(i) You dont have to add dependencies in your code.
angular.module('library.crud').factory('bookService', bookService);
(ii) Add reference for your controller and service in your index.html.
<script src="app/appConfig.js"></script>
<script src="app/service.js"></script>
<script src="app/controller.js"></script>
The main reason this error occurs when everything else looks ok is because you did not include your js files in your index.html. Based on your screenshot, it looks like you have your controllers and services in separate files. Make sure you put them after your appConfig.js file in index.html.
Another issue I see is in your service file.
angular
.module('library.crud', [])
.factory('bookService', bookService);
should be
angular
.module('library.crud')
.factory('bookService', bookService);
If you include square brackets as a second parameter in the .module line, angular will think you are creating a new app instead of trying to register your service/controller to your existing app.
Also, it is highly recommend to use ui-router instead of NgRoute in any Angular1.x applications: https://github.com/angular-ui/ui-router
I have a header which remains common for all the pages. So, I included it in my index page like this.
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="assets/lib/angular.js"></script>
<script src="assets/lib/angular-route.js"></script>
<script src="headerController.js"></script>
<script src="HomeController.js"></script>
<script src="app.js"></script>
</head>
<body>
<div class="header" ng-include="'header.html'"></div>
<div class="main" ng-view></div>
</body>
</html>
header.html
<ul>
<li>{{vm.myName}}"></li>
</ul>
My app.js file looks like this.
( function () {
angular.module('myApp', [
'ngRoute',
'myApp.header',
'myApp.home',
])
.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/home', {
controller: 'HomeController',
templateUrl: 'homeView.html',
controllerAs: 'vm'
})
.otherwise({
redirectTo: '/home'
});
}]);
})();
I'm not including home controller or view as they have less importance here now. What I'm trying to do is, to pass a value from headerController.js to it's view header.html
As you can see, there is only one variable in my header.html
On the other side, headerController.js communicates with a backend service and fetches this result. And, I'm sure data is being returned by the service, I can see it in console and it looks like this:
{"myName":"Amelia Earheart"}
and here is my headerController.js
(function() {
angular
.module('myApp.header', [])
.factory('myCommonService', function($http) {
var baseUrl = 'api/';
return {
getName:function() {
return $http.get(baseUrl + 'getName');
}
};
})
.controller('CommonController', function($scope, $routeParams, myCommonService) {
var vm = this;
myCommonService.getName().success(function(data) {
vm.myName = data.myName;
});
});
})();
Can anyone tell why I am not getting the value in html view?
You should link your view with your controller.
Actually, your CommonController is not referenced anywhere. Try adding a ng-controller attribute to the div.header :
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="assets/lib/angular.js"></script>
<script src="assets/lib/angular-route.js"></script>
<script src="headerController.js"></script>
<script src="HomeController.js"></script>
<script src="app.js"></script>
</head>
<body>
<div class="header" ng-controller="CommonController" ng-include="'header.html'"></div>
<div class="main" ng-view></div>
</body>
</html>
And also you need to bind the value to the $scope (which is your model) rather to this. Your controller should look like this :
.controller('CommonController', function($scope, $routeParams, myCommonService) {
myCommonService.getName().success(function(data) {
$scope.myName = data.myName;
});
});
If you want to use "vm" in your header's view, you can change the ng-controller to ng-controller="CommonController as vm". This should do the trick.
If you don't do this, you'll have to update your header.html to :
<ul>
<li>{{myName}}</li>
</ul>
I am using "prettyprint" along with "AngularJs" which is working very well, but only issue is if I use routing, then the prettyprint function is not working (as it might have been configured to run on pageLoad). Now, what if I am going to various ng-view pages and coming back? How to run the prettyprint function even on route change?

Having an issue using the ng-view to render a template from my controller.
The index.html file is initially served to the client and looks like.
<!doctype html>
<html lang="en" ng-app="hlmApp">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

#RenderSection("BootScript")
<!-- app.js will load the angular module -->
<script src="#Model.Root.Resource/bower_components/angular/angular.js"></script>
<script src="#Model.Root.Resource/bower_components/angular-route/angular-route.js"></script>
<script src="#Model.Root.Resource/app/app.js"></script>

</head>
<body>
<div class="container">
<div class="navbar">
<div class="navbar-inner">
<ul class="nav">
<li>A link here</li>
</ul>
</div>
</div>
<div ng-view></div>
#*<div ng-controller="tempController">{{Heading}}</div>*#
</div>
#RenderBody()
</body>
</html>
the server pushes down my app.js and controllers.js file along with the deps.
/// ap.js ///
var hlmApp = angular.module('hlmApp', ['ngRoute', 'MyTempControllers']);
hlmApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/Holdings', {
templateUrl: 'templates/temp.html',
controller: 'controllers/tempController'
});
}]);
the controller is pretty simple and is as follows
var MyTempControllers = angular.module('MyTempControllers', []);
MyTempControllers.controller('tempController', ['$scope', function () {
console.log("stuff happening");
$scope.Heading = "Hello World";
}]);
then the html template is as follows
<div>
<h3>{{Heading}}</h3>
</div>
When I use the ng-view nothing ever renders. the controller is never triggered in the debugger. If I specifically call out the controller via the ng-controller then everything shows up. can someone point out my error here?
You need these 3 changes:
1) add $scope as a parameter in your controller function
MyTempControllers.controller('tempController', ['$scope', function ($scope) {
...
}]);
2.
Change
controller: 'controllers/tempController'
to
controller: 'tempController'
FYI, the naming convention for a controller is to begin with a capital letter for Controller.
3. In addition, you should add a
.otherwise({
template: templates/temp.html,
controller: 'tempController'
});
so that when no route matches, it goes to default-page-name.html. This is what's happening in your case, when you first load the page, no route matches. If you want to see temp.html, you have to 1) either click on a link that goes to #/Holdings, or 2) use '/Holdings' as the "otherwise" route, as indicated above.
Try this:
hlmApp.config(['$routeProvider', function ($routeProvider) {
$routeProvider.when('/Holdings', {
templateUrl: 'templates/temp.html',
controller: 'tempController' // just the name
});
}]);
and also $scope is missing in parameters:
MyTempControllers.controller('tempController', ['$scope', function ($scope) {
console.log("stuff happening");
$scope.Heading = "Hello World";
}]);
I am learning Angularjs from Tuts+ Easier JavaScript Apps with AngularJS tutorial. Now I am at the part where they discussed Routing Primer using ng-view. I am trying to show the list page contents in ng-view of index page. For some reason nothing is shown when I load index.html. I found from searching that From angular 1.2.0, ngRoute has been moved to its own module. I have to load it separately and declare the dependency. But still I can't show anything from my list page.
index.html
<!doctype html>
<html ng-app="myApp">
<head>
<title>Angular App</title>
<script src="js/angular.min.js"></script>
<script src="js/angular-route.min.js"></script>
<script src="app.js"></script>
</head>
<body>
<div ng-controller="Ctrl">
<div ng-view></div>
</div>
</body>
</html>
list.html
<h3>List</h3>
<ul>
<li ng-repeat="contact in contacts">
{{contact.name}}: {{contact.number}}
</li>
</ul>
app.js
var app = angular.module('myApp', ['ngRoute']);
app.config(function($routeProvider) {
$routeProvider.when('/', {
templateUrl: 'list.html',
controller: 'Ctrl'
});
});
app.controller('Ctrl', function($scope){
$scope.contacts = [
{ name: 'Shuvro', number: '1234' },
{ name: 'Ashif', number: '4321' },
{ name: 'Anik', number: '2314' }
];
});
Remove the ng-controller from the div like this:
<body>
<div >
<div ng-view></div>
</div>
</body>
To void "miss-routings" add the otherwise to the main configuration like: otherwise({ redirectTo: '/'});
app.config(function($routeProvider) {
$routeProvider.when('/', {
templateUrl: 'list.html',
controller: 'Ctrl'
}).otherwise({ redirectTo: '/'});
});
