I am learning Angularjs and Nodejs by developing a project.
I have followed this tutorial and organised my folder structure and route configurations.
Problem:
I have added a method called isActive to update ng-class based on tab click. But when I click the tab it is not calling the isActive method.
My guess is, I have done something wrong in appRoutes.js but not sure how to fix this. I am able to reach the MainController but not the methods in it.
I have another question, I need to make the Home tab active when I enter the application or when I clicked on home tab or when I click on application header too.
Below is the html and the js codes.

appRoutes.js
angular.module('appRoutes', []).config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl: 'views/partials/home.html',
controller: 'MainController'

.when('/home', {

MainCtrl.js
angular.module('MainCtrl', []).controller('MainController', function($scope) {
console.log('Main Controller');
$scope.isActive = function(destination) {
console.log($location.path());
return destination === $location.path();
}
});
Your navigation_main.html is outside of controller scope. That's the main reason. Try to create separate controller for you navigation like this
.controller('NavCtrl', function($scope) {
isActive = function(destination) { /*...*/ }
}
Put it into file js/nav.js and add to your html
<script type="text/javascript" src="js/nav.js"></script>
And then add this controller to your navigation_main.html code
<div ng-controller="NavCtrl">
About problem not reaching isActive method:
Try to reorganize:
<script type="text/javascript" src="js/controllers/MainCtrl.js"> </script>
<script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
<script type="text/javascript" src="js/appRoutes.js"></script>
<script type="text/javascript" src="js/app.js"></script>
into:
<script type="text/javascript" src="js/app.js"></script>
<script type="text/javascript" src="js/appRoutes.js"></script>
<script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
<script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
May be you forget to add .otherwise
.when('/', {
templateUrl: 'views/partials/home.html',
controller: 'MainController'
})
.when('/home', {
templateUrl: 'views/partials/home.html',
controller: 'MainController'
})
.otherwise({
redirectTo: '/'
});
Update :
Try this -
In navigation_main.html
<li ng-class="{'active' : path}" >
Image Operation's
</li>
MainCtrl.js
angular.module('MainCtrl', []).controller('MainController', function($scope) {
console.log('Main Controller');
$scope.itemClicked= function(destination) {
$scope.path = destination;
}
});
You can try angular ui-router for your routing and for adding an active class when a state is active. You only need to add ui-sref-active="YourActiveClassHere". Angular UI-Router
Try to change the order of this,
<script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
<script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
<script type="text/javascript" src="js/appRoutes.js"></script>
<script type="text/javascript" src="js/app.js"></script>
To this,
<script type="text/javascript" src="js/app.js"></script>
<script type="text/javascript" src="js/appRoutes.js"></script>
<script type="text/javascript" src="js/controllers/MainCtrl.js"></script>
<script type="text/javascript" src="js/controllers/HomeCtrl.js"></script>
Try to add ng-click=isActive('/home'), in your a tag.
<li ng-class="{active : activeClass == 'home'}" id="nav_home">
<a href="/home" ng-click=isActive('/home')>Home</a>
</li>
In your MainCtrl add this line,
$scope.activeClass = '';
$scope.isActive = function(destination) {
$scope.activeClass = destination;
}

I want to insert header and nav bar into index.html
When header and nav bar are in index.html, My app works well.
but seperate these files to html and try to load, ui-view do not load script files.
So logout function does not work when ui-view loaed header.html
On the other hand, css works well.
I tried to follow answers like
Angularjs does not load scripts within ng-view
or
html partial is not loaded into ui-view
but it did not help to fix my problem..
Why this situation occurred?
Please any handsome or pretty developer help me..
These are my code.
app.js
'use strict';
var mainApp = angular
.module('adminApp', [
'ngAnimate',
'ngCookies',
'ngResource',
'ngRoute',

mainApp.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/admin/login');
$stateProvider
.state('root',{
url: '',
abstract: true,
views: {
'headerContainer': {
templateUrl: 'views/header.html',

}); // This is for remove all cookies
};
});
main.js
$('.top-nav li a').on('click', function (e) {
console.log('Clicked header li');
});
It seems like you haven't used controller alias while calling logout method
ng-click="header.logout();"
As #pankaj said you need to declare the logout method on your controller alias
ng-click="header.logout();"
And the same applies for your js. You have to reference logout with this keyword since you are using controller as syntax
mainApp.controller('HeaderCtrl', function ($scope, $cookieStore) {
var vm =this;
vm.logout = function () {
angular.forEach($cookies.getAll(), function (v, k) {
$cookies.remove(k);
}); // This is for remove all cookies
};
});
For more Info: AngularJs "controller as" syntax - clarification?
I'm learning Angular JS and I'm got stuck when using ui-view.
I don't know ui-view or something else is trouble. But my navbar didn't appear.
Any help must be great!

Help, please!
As Claies pointed out you need to have descendants states, so that only your parent abstract state would be activated. Please check the answer here
In the run config you have to initialize/activate the root url by calling $state.go('your.state.name') or you have to use ng-route's otherwise api to activate the initial state. Here I have used unnamed view for content in index.html
Hello guys i am trying to use angular ui-router for nested routing in my website but i don't know where i am going wrong
this is my code
app.js
var faqApp = angular.module('faqApp', ['ui.router']);
faqApp.config(function($stateProvider, $urlRouterProvider){
$urlRouterProvider.otherwise('/home');
$stateProvider
.state('home',{
url: '/home',
templateUrl: 'templates/home.html',
controller: 'homeCtrl'
})
.state('home.contactform', {
templateUrl: 'templates/contactform.html',
})
});
home.html

In the above code i am calling 'home.html' in index.html through ui-view and then calling contactform.html in home.html but contactform.html is not loaded.
You need to define the url too,
.state('home.contactform', {
url: "/contactform",
templateUrl: 'templates/contactform.html',
})

So I'm trying to run an Angular app with a Rails API on Chrome.
I'm trying to render very simple views from their respective controllers.
My users.js controller:
'use strict';
var rantlyApp = angular.module('rantlyApp', ['ngRoute']);
rantlyApp.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/users', {
templateUrl: '/views/users.html',
controller: 'UsersCtrl'
});
}])
.controller('UsersCtrl', ['$scope', '$http', function ($scope, $http) {
$http.get('http://localhost:3000/api/users/').success(function(data) {
$scope.users = data.users;
});
$scope.foos = ['foo', 'bar', 'baz'];
}]);
users.html view:
<div ng-controller='UsersCtrl'>
<h1>Users</h1>
<ul ng-repeat="user in users">
<li>{{user.first_name}}</li>
</ul>
<ul ng-repeat="foo in foos">
<li>{{foo}}</li>
</ul>
</div>
The users page renders fine, and I get all the data I want. But when I try to load my main page, I get nothing. No errors, just a blank screen (though the navbar and everything else I have in my index.html loads properly).
My main.js controller:
'use strict';
var rantlyApp = angular.module('rantlyApp', ['ngRoute']);
rantlyApp.config(['$routeProvider', function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: '/views/main.html',
controller: 'MainCtrl'
});
}])
.controller('MainCtrl', ['$scope', function ($scope) {
$scope.awesomeThings = [
'foo',
'bar',
'baz'
];
$scope.addThing = function() {
$scope.awesomeThings.push($scope.newThing);
$scope.newThing = '';
};
}]);
main.html view:
<div ng-controller="MainCtrl">
<form ng-submit='addThing()'>
<div class="form-horizontal">
<input type="text" ng-model="newThing">
<input type="submit" value="Add Thing">
</div>
</form>
<li ng-repeat='thing in awesomeThings'>
{{thing}}
</li>
<h4>Awesome things: {{awesomeThings}}</h4>
<h4>Cool things: {{coolThings}}</h4>
</div>
When I look at the inspector in the Network tab for the "/users" route, it loads users.html. This doesn't happen for the "/" route. I expect it to load main.html, but I get nothing.
The strange thing is, when I copy all of my code from my main.js and just throw it into my users.js, everything works fine. This told me maybe I wasn't loading it properly into the index.html page, but it seems to me that I am.

I'm extremely new to Angular so it's quite possible I'm missing a fundamental step in setting up the controllers. Since my code works based purely off of which file I have it in, I have a feeling I'm not configuring something properly in Angular.
Any help is greatly appreciated. Thanks!
When you write
var rantlyApp = angular.module('rantlyApp', ['ngRoute']);
You are creating a new module called rantlyApp and removing any old module with the same name. So when the users.js script runs it overwrites what you defined in main.js.
Instead define your module once, and retrieve it with:
var rantlyApp = angular.module('rantlyApp');
Check the documentation.
