How to use ng-switch as a router for my pages with ngRoute & ngView?

Here is the highlevel skeleton of my Angular SPA. My application is about college degree offerings. In that engineering page has a separate left nav which is currently built on ng-switch which i want to convert as route. How do i do that just using angular's native routing angular-route.js?
**app.js**
(function(){
var app=angular.module("myCollege",['ngRoute']);
app.config(['$routeProvider','$locationProvider',
function($routeProvider,$locationProvider) {
$routeProvider
.when('/', {
templateUrl:"app/views/home.html",
controller:"homeController",
}
.when('/engg', {
templateUrl:"app/views/engineering.html",
controller:"engineeringController",
})
.when('/med', {
templateUrl:"app/views/medical.html",
controller:"medicalController",
})
}]);
I have left nav in engineering.html using ng-switch which i want to
convert as sub-route of the application.This left nav of engineering
page is not inside of ngView. How do i acheive this using angular's
native ngRoute/angular-route?
**engineering.html**
<div nav ng-switch on="pagename()">
<div ng-switch-when="Civil Engineering">
<div civil-directive> </div>
</div>
<div ng-switch-when="Computer Engineering">
<div computer-directive> </div>
</div>
<div ng-switch-when="Nano Engineering">
<div nano-directive> </div>
</div>
<div ng-switch-when="Electrical Engineering">
<div electrical-directive> </div>
</div>
</div>
EngineeringController.js
(function() {
var app =angular.module("collegeApp");
var engineeringController= functino($scope,$rootscope,$location)
{
$scope.pagename = function() {
return $location.path();
};
app.controller("engineeringController",['$scope','$rootScope','$location',engineeringController])
}());
The above logic is not working for me. Can someone tell me where i am doing the wrong?

Not a good practice but here's what you want to do if you want to use ng-switch:
In your html, as you write for example:
<!-- don't forget to reference your app and your controller -->
<button ng-click="goTo('/page1')">Go to page 1</button>
<button ng-click="goTo('/page2')">Go to page 2</button>
<div nav ng-switch on="pagename()">
<div ng-switch-when="'/page1'"></div>
<div ng-switch-when="'/page2'"></div>
</div>
<div ng-view> </div>
in js
Config your routes
app.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/page1', {
templateUrl: 'views/page1.html'
}).
when('/page2', {
templateUrl: 'views/page2.html'
}).
otherwise({
redirectTo: '/'
});
}])
and add the following in your controller:
$scope.pagename = function() { return $location.path(); };
$scope.goTo = function(page){
$location.path(page);
}
In the html above, ng-switch will use the $location.path() variable to know which view to display.
As I said this is not a good practice, because your controller isn't suppose to deal with routes.

browser back button not loading proper content when using ng-view (angular js in front-end; node+express on backend)

Intially when i use / i can see home.html getting sucessufully to index.html then i click <a ng-href="#/club> the club page is loaded successfully, but then i press back button then only header and footer of home.html is seen and in between complete blank page
Below are following files:
appRoutes.js --> for routing on angular side
clubCtrl.js --> club controller
clubService.js --> club service to fill data from node
Routes.js --> partial sample of retriving data from database and sending response
club.html --> partial club view file
home.html --> partial home page
index.html --> file on which club.html will get dynamically displayed using ng-view.

ng-click and ng-submit doesn't work

i have a angular application with phonegap where i have a login form and login controller.
The problem is that the ng-submit doesn't work. Normaly the submit call the fonction formConnexion() but nothing happens. So, i tried with just a alert, but it's the same result...
After i tried with a ng-click and same result. Then, i wanted try to call a sample variable in the scope in the template ($scope.test) and it doesn't display. And the console.log('salut!!') doesn't dispaly when i am on the login page.
Which made me think that my controller it doesn't associate to the template.
But i have the ng-controller in my div with the good name controller.
Then, i thought that angular it's was worse installing but no because the other directives work (ng-if, ng-src, ...)
So, if you have a idea to solve this problem, I do not mind :)
here the code for the template :
login.html
<div class="row jumbotron" style="margin:10px" ng-controller="LoginCtrl">
<div class="col-lg-8 col-lg-offset-2 col-md-8 col-md-offset-2 col-sm-8 col-sm-offset-2 col-xs-8 col-xs-offset-2">
<h1>{{ test }}</h1>
<form class="form-horizontal" ng-submit="alert('alert')">
<div class="form-group">
<label for="login" class="control-label">Login</label>
<input type="text" name="login" class="form-control" ng-model="formData.login">
</div>
<div class="form-group">
<label for="password" class="control-label">Password</label>
<input type="password" name="password" class="form-control" ng-model="formData.password">
</div>
<button type="submit" class="btn btn-md btn-success">Connexion</button>
</form>
click
<img ng-src="images/accueil.png" class="accueil img-responsive">
</div>
</div>
and here the controller :
login.js
'use strict';
appStat.controller('LoginCtrl', function ($scope, $rootScope, $http, $location) {
console.log("salut!!");
$scope.formData = {};
$scope.test = "test";
$scope.toto = function() { alert('alert'); };
/**
* Connect l'user
*/
$scope.formConnexion = function () {...}
});
and here my app.js :
app.js
'use strict';
var appStat = angular.module('posStatsPhoneGap', [
'ngCookies',
'ngResource',
'ngSanitize',
'ngRoute',
'ngResource',
'ui.bootstrap',
'ngMessages',
'ngAnimate',
'ngAria',
'ngTouch',
'picardy.fontawesome'
])
.config(['$routeProvider', '$compileProvider', function ($routeProvider, $compileProvider) {
$compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|file|tel):/);
$compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|file|tel):/);
$routeProvider
.when('/', {
templateUrl: 'views/login.html',
controller: 'LoginCtrl'
})
.when('/main', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
})
.when('/stat', {
templateUrl: 'views/stat.html',
controller: 'StatCtrl'
})
.otherwise({
redirectTo: '/'
});
}
]);
Thank you in advance !

Following from my comment Try something like this:
Create a Controller file & a controller within it Create a angular
module within the controller file
Create a controller.js file then create a angular module see code below:
//Within your controller.js file
var myApp = angular.module('myApp', []);
myApp.controller('myController', function($scope, $http){
$scope.Data = "Alert Alert";
// Create a function within the scope of the module
$scope.myFunc = function(){
alert($scope.Data)
};
});
Then within your HTML file call the function on-Click see code below:
Note: Don't forget to add the controller you created into your HTML code. I usually add it in the body tag
<body ng-controller="myController">
<button ng-click="myFunc()">Make Request Button</button>
</body>
See a live example here:
http://plnkr.co/edit/sQ0z7TlyWv5fM5XyfujK?p=preview
Also a note: ng-click is mostly used for any click events you are trying to perform within your angular app but ng-submit is mostly used when working with a HTML form submission.

Use ng-submit in you form as:
<form ng-submit="submit()">
function Ctrl($scope) {
$scope.list = [];
$scope.text = 'hello';
$scope.submit = function () {
if ($scope.text) {
$scope.list.push($scope.text);
$scope.text = '';
}
};
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app>
<div ng-controller="Ctrl">
<form ng-submit="submit()">Enter text and hit enter:
<input type="text" ng-model="text" name="text" />
<input type="submit" id="submit" value="Submit" /> <pre>list={{list}}</pre>
</form>
<button ng-click="submit()">Submit 2</button>
</div>
</div>

I found the error. It was caused by having 2 controllers with the name 'LoginCtrl'. It was a stupid copy/paste error.

I have created one working code for the above question for 4 different type of HTML element, for complete code please follow the below URL -
http://plnkr.co/edit/Tm2Rtbt3xsv4pKzcPQCw?p=preview
<body ng-controller="ExampleController">
<button ng-click="setButton()">set button</button>
<div content="snippetContentFirst"></div>
<div content="snippetContentSecond"></div>
<div content="snippetContentThird"></div>
<div>
<ul content="snippetContentFour"></ul>
</div>
</body>

How do I refresh my ng-repeat?

I have a controller (called "catalogueController") that manages my search box and my search page. I have the controller initially set the page to automatically call the search function defined in "catalogueController" when the app loads to pre-load my array of items (called Inventory) to be repeated via ng-repeat in the page.
The process runs like this:
1. I submit the search form.
2. "catalogueController" will send the search term to my factory (called "Search").
3. "Search" will have a function which will make a server call to query my database for that particular search.
4. The database will send the results of the search to the "Search" factory.
5. The "Search" factory will send the results to the "catalogueController" controller.
6. "catalogueController" will update the $scope.Inventory to be equal to the new result that I was received.
My problem is that ng-repeat does not refresh itself to display my new and updated $scope.Inventory array. $scope.Inventory definitely is updated (I have made sure of this through various console logs).
I have also tried to use $scope.$apply(). It did not work for me.
Thank you in advance for your help!
Here is my code:
HTML Template
<form role="search" class="navbar-form navbar-left" ng-controller="catalogueController" ng-submit="search(search_term)">
<div class="form-group">
<input type="text" placeholder="Search" class="form-control" ng-model="search_term">
</div>
<button type="submit" class="btn btn-default">Search</button>
</form>
<main ng-view></main>
catalogue.html partial
<div id="main" class="margin-top-50 clearfix container">
<div ng-repeat="items in inventory" class="row-fluid">
<div class="col-sm-6 col-md-3">
<div class="thumbnail"><img src="image.jpg" alt="..." class="col-md-12">
<div class="caption">
<h3>{{ items.itemName }}</h3>
<p>{{ items.description }}</p>

var myApp = angular.module('qcbApp', ['ngRoute', 'ngCookies', 'appControllers']);

$routeProvider.
when('/login', {

myApp.controller('catalogueController', ['$scope', 'Search', function($scope, Search) {
var time = 0;
var searchCatalogue = function(search) {
$scope.inventory = null;
console.log("Controller -- "+search);
Search.searchCatalogue(search)
.then(function(results) {
console.log(results);
$scope.inventory = results;
});
};
if(time == 0)
{
searchCatalogue('');
time++;
}
$scope.search = function(term) {
searchCatalogue(term);
}
}]);
"Search" Factory
myApp.factory('Search', ['$http', '$q', function($http, $q) {
function searchCatalogue(term) {
var deferred = $q.defer();
console.log("Factory -- "+term);
$http.post('/catalogue_data', {term: term}, {headers: {'Content-Type': 'application/json'}})
.success(function(result) {
console.log(result[0].SKU);
deferred.resolve(result);
console.log("Factory results -- "+result);
});
return deferred.promise;
}
return {
searchCatalogue: searchCatalogue
}; //return
}]);

I think the problem is the ng-repeat can not access the inventory in scope. You have to create a div which contains both the form and the ng-repeat.
The html should be:
<div ng-controller="catalogueController">
<!-- Move the controller from the form to parent div -->
<form role="search" class="navbar-form navbar-left" ng-submit="search(search_term)">
<div class="form-group">
<input type="text" placeholder="Search" class="form-control" ng-model="search_term">
</div>
<button type="submit" class="btn btn-default">Search</button>
</form>
<div id="main" class="margin-top-50 clearfix container">
<div ng-repeat="items in inventory" class="row-fluid">
<div class="col-sm-6 col-md-3">
<div class="thumbnail"><img src="image.jpg" alt="..." class="col-md-12">
<div class="caption">
<h3>{{ items.itemName }}</h3>
<p>{{ items.description }}</p>
<p>Buy <a href="#" role="button" class="btn btn-default">More Info</a></p>
</div>
</div>
</div>
</div>
</div>

I've seen the situation a few times where when you are updating a property directly on the $scope object there are interesting problems around databinding to that value (such as inventory). However if you databind to an object property of an object then the databinding works as expected. So for example use a property on $scope. I believe this is a copy by value vs copy by reference issue.
Update all your inventory references as follows
$scope.data.inventory = result;
Also don't forget to update your inventory reference in the html template:
<div ng-repeat="items in data.inventory" class="row-fluid">
Update: I made this plunk to figure it out - http://plnkr.co/edit/0ZLagR?p=preview
I think the primary problem is you have the controller specified twice. I removed it from the form and it started working.

Route not working in angular.js with node/express

I am getting a 404 and cannot figure out why. I know my mongoDB server and node server are working because I can query and view my services. Now I am trying to implement an angular.js frontend on top of the services but I keep getting a 404 when I try to access my "home state".
// Configure the app to use routing. These $ tags are referencing the angular ui-router import.
app.config([
'$stateProvider',
'$urlRouterProvider',
function($stateProvider, $urlRouterProvider) {
// tells your route what controller to use when it gets there
$stateProvider
.state('home', {
url: '/home',
templateUrl: '/home.html',
controller: 'MainCtrl'
resolve: {
postPromise: ['posts', function(posts){
return posts.getAll();
}]
}
});
$stateProvider
.state('posts', {
url: '/posts/{id}',
templateUrl: '/posts.html',
controller: 'PostsCtrl'
});
// .otherwise means "route to this place if the url is anything else" || like an if/else for url routing
$urlRouterProvider.otherwise('home');
}]);
This is some code from app.js that is throwing the code. Standard express generated code here.
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
This is the javscript that should be displaying, which is located in my index.ejs view page in node.
<script type="text/ng-template" id="/home.html">
<div class="page-header">
<h1>Flapper News</h1>
</div>
<div ng-repeat="post in posts | orderBy:'-upvotes'">
<span class="glyphicon glyphicon-thumbs-up"
ng-click="incrementUpvotes(post)"></span>
{{post.upvotes}}
<span style="font-size:20px; margin-left:10px;">
<a ng-show="post.link" href="{{post.link}}">
{{post.title}}
</a>
<span ng-hide="post.link">
{{post.title}}
</span>
<span>
Comments
</span>
</div>
<form ng-submit="addPost()"
style="margin-top:30px;">
<h3>Add a new post</h3>
<div class="form-group">
<input type="text"
class="form-control"
placeholder="Title"
ng-model="title"></input>
</div>
<div class="form-group">
<input type="text"
class="form-control"
placeholder="Link"
ng-model="link"></input>
</div>
<button type="submit">Post</button>
</form>
</script>
Also for reference, my imports on the index.ejs page
<head>
<title>Flapper News</title>
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.min.js"></script>

<script src="/javascripts/angularApp.js"></script>
<style> .glyphicon-thumbs-up { cursor:pointer } </style>
</head>
I am baffled by this 404 because I feel like I have a good understanding of this in-line templating routing set up. I have tried everything I can think of and nothing will resolve this 404.

It looks like you made the same mistake I did following this tutorial: you deleted the root route in routes/index.js which is need to serve up the initial index.ejs file. Here it is to add back to your route:
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
