AngularJS - How to load ng-view based on the URL? - angularjs

I have been following the AngularJS tutorials on CodeSchool.
So I have views/index.html which contains all of my boilerplate code that is identical for each page. Then my templates for each page are in views/templates/ which I want included in the index.html page. So when the home page loads, it loads the views/index.html and includes the views/templates/index.html.
views/
index.html
templates/
index.html
contact.html
about.html
Currently I have
<div id="menu">
<a id="menu_home" href="/#/index" ng-click="menu.set(0)" ng-class="{current:menu.isSet(0)}">Home</a>
<a id="menu_hire" href="/#/hire" ng-click="menu.set(1)" ng-class="{current:menu.isSet(1)}">For Hire</a>
<a id="menu_info" href="/#/info" ng-click="menu.set(2)" ng-class="{current:menu.isSet(2)}">Info</a>
</div>
<div id="main">
<ng-view></ng-view>
</div>
which works great. So only the required html is requested and inserted into the page.
But my problem is that the URL doesn't change in the browser. So if a user went directly to mysite.com/contact it wouldn't work. How can I load the page correctly if the mysite.com/contact or mysite.com/about pages are accessed directly?
I have also got it working using the ngRoute module, but the same issue remains when a user goes directly to a page.
Thanks.

You should use ngRoute and $routeProvider similar to the following.
var navigationRoutes = angular.module('navigationRoutes', ['ngRoute']);
/**
* Load routes for navigation using ngRoute
*/
navigationRoutes.config(function ($routeProvider) {
$routeProvider
.when('/index', {
templateUrl: 'app/components/index/index.view.html',
controller: 'IndexCtrl'
})
.when('/contact', {
templateUrl: 'app/components/contact/contact.view.html',
controller: 'ContactCtrl'
})
.otherwise({
redirectTo: '/dashboard'
});
});
This way you can also specify a different controller based on the URL.
UPDATE
In your index page if you add -
<div class="view">
<div ng-view></div>
</div>
To your main index.html page the the contents of the $routeProvider selected file will be shown within this div. You just need to make sure that you add the tag for the controller.js files in the index.html page.

You will need to make these settings in the web server to redirect all urls to your index page where you load your angular app which in turn will handles the routes

IIS Virtual Directory with MVC6 Angular Routing 1.4.5

I have a MVC6/Angular site that will have multiple applications, but for now it just has one. When it is complete an example will be App1 and App2 being.cshtml pages with only a div with a data-ng-app and data-ng-view attribute:
mysite.come/virtualdir/App/App1:
<div class="row" data-ng-app="app-app1">
<div data-ng-view></div>
</div>
mysite.come/virtualdir/App/App2
<div class="row" data-ng-app="app-app2">
<div data-ng-view></div>
</div>
For angular, I understand if I have a virtual directory in IIS i need to include in my the header section of the _Layout.cshtml (Actually putting this in the _Layout will break development):
<base href="#Url.Content("~/")" />
My original templateUrl and angular links for app1 in development are:
$routeProvider.when("/", {
templateUrl: "/views/app1/index.html"
});
$routeProvider.when("/items", {
controller: "receiveController",
controllerAs: "vm",
templateUrl: "/views/app1/receiveView.html"
});
// typical link in html page for app1
<a data-ng-href="#/items"></a>
When I deploy to IIS i need to have the routing below to get to my index page to load when the the user navigates to mysite.come/virtualdir/App/App1
$routeProvider.when("/", {
templateUrl: "../views/app1/index.html"
});
After that none of my other links work:
<a data-ng-href="#/items"></a> navigates me to mysite.com/virtualDir/#/items
How do I structure my hrefs in the html page? i tried playing around with the ../#/items/ and ..#/items and adding the .. to the other templateUrl but nothing seemed to work. Thanks
so it seems like the simplest solution is to define the routes and hrefs as below. My problem was not having all three of these combinations at once. I thought angular defined the root of the angular routes based on my ~/App/App1 where I defined:
<div class="row" data-ng-app="app-app1">
<div data-ng-view></div>
</div>
so I needed in the app.js:
$routeProvider.when("/", {
templateUrl: "views/app1/index.html"
})
# the top of my _Layout.cshtml
<base href="/app/">
my href:
data-ng-href="App/App1#/items"

Angular and ngRoute; Open in New Window

I'm looking for a way to use ngRouting to open a template in a new window. I have an ng-view div set up in my index page that allows me to populate the data in my central page, but if the user chooses to open a link in a new window/tab, the page comes back 404, since it is expecting to have ngRoute to load it's controllers and templates. Is there any way to allow Angular to handle this option?
Below is my index page
<script type='text/javascript' src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.13/angular.min.js"></script>
<script type='text/javascript' src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.13/angular-route.min.js"></script>
<body ng-controller="routeController" ng-init="init()">
<div id="wrapper" class="page">
<ul id='settingsLink' class='settingsLink' ng-mouseleave="hideSettingsLink()">
<li>Login</li>
<li>Page 2</li>
<li>Page 3</li>
</ul>
<div id="viewcontent">
<div ng-view></div>
</div>
</div>
</body>
And here is my routeController config code:
angular.module('myApp').config(function($routeProvider, $locationProvider, $sceDelegateProvider){
$routeProvider
// route for the Login page
.when('/login', {
templateUrl : 'pages/login.html',
controller : 'AuthenticateController'
})
// route for page 2
.when('/page2', {
templateUrl : 'pages/page2.html',
controller : 'Page2Ctrl'
})
// route for page 3
.when('/page3', {
templateUrl : 'pages/page3.html',
controller : 'Page3Ctrl'
});
$locationProvider
.html5Mode(false)
.hashPrefix('!');
});
Let's say I want to open Page 3. If i right-click and try to open in a new tab, my page resolves back to "index.html#!/login", instead of "index.html#!/page3".
If you're using ngRoute in HTML5Mode, you won't have a hash in the URL and the server will think you're trying to access a file when in reality you're getting an Angular view. You need to use hashbang mode to fix this. In the place where you configure your routes (with $routeProvider), add this:
$locationProvider
.html5Mode(false)
.hashPrefix('!');
Now in your links, add the hash:
link

AngularJs one page app ng-view trouble

I am brand new to AngularJs and after following some tutorials I decided to try to implement a one page app into one of my projects. I have it working but I had one question about this code. Could I change what is shown on the first page before they navigate to anything? I don't want it shown on every page just when they first land on it before clicking any links.
var app=angular.module('single-page-app',['ngRoute']);
app.config(function($routeProvider){
$routeProvider
.when('/',{
templateUrl: 'home.html'
})
.when('/about',{
templateUrl: 'about.html'
});
});
app.controller('cfgController',function($scope){
/*
Here you can handle controller for specific route as well.
*/
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="single-page-app">
<div ng-controller="cfgController">
<div>
<nav>
<ul>
<li>Home</li>
<li>About us</li>
</ul>
</nav>
</div>
<br/>
<div ng-view>
<!--
This DIV loads templates depending upon route.
-->
</div>
</div>
</body>
The pages load fine and if I try to add something to the index.html under ng-view it doesn't show up on the page.
You want to put the content to show up when a user first hits your site under in your "home.html" page which is linked to your "/" route for "ng-view". When a user clicks a link, they will be taken to a new route, and the code/ will be replaced by the route they selected.

ui-route not redirecting to external page

From a modal dialog I present a general terms link that should redirect the user to a new page.
I would like to re-use my layout skeleton (background, logo ans basic styles) for the terms page, without the content of the master page (eg. search function, navigation etc). To achieve this I try to inject into a new window the terms template inside the ui-view="main" used for the normal site content (where is loaded the content of the modal dialog, as instance), but I get the error Could not resolve 'terms' from state 'login' (login is the current state where the modal dialog is).
Below the termsPage module with the ui-router state I would like to load:
angular.module('termsPage').config(function ($stateProvider) {
$stateProvider
.state('terms', {
url: '/terms',
views: {
'main': {
controller: 'TermsCtrl as Terms',
templateUrl: '/modules/staticPages/views/termsPage.html'
}
}
});
});
My index.html file:
<!-- Other tags excluded for sake of semplicity -->
<body ng-app="myApp">
<!-- Here I inject all the content -->
<div id="wrapper" ui-view="main">
</div>
Below the app module and view, where the content of the application is correctly loaded. Also the modal dialog from which I would like to redirect to the external page is loaded here.
angular.module('app').config(function($stateProvider){
$stateProvider
.state('app', {
url: '/app',
views:{
'main' : {
controller : 'AppCtrl',
templateUrl: 'modules/app/views/app.html'
}
}
});
});
Below app.html:
<div id="container">
<div class="browser">
<div class="content" ui-view="content" style="position:relative;">
</div>
My goal would be to create a sibling of app.html, injecting in main placeholder the content of my general terms page. Inside the modal dialog controller I use $state.go for the redirection:
$state.go('terms');
In my case the problem was that I did not registered the new module ('termsPage') as dependency in my main module:
angular.module('myApp', ['login','forms','termsPage'], function($urlRouterProvider){ ...}
Now that the module is registered, I can navigate correctly to state 'terms'.
Hopefully the case above might help someone else, getting hints for his/her case.

ionic - ion-nav-view not working

I am building a ionic pacakage, having multiple views. I use the route provider to navigate between different views.
app.js
.config(function($routeProvider,$locationProvider){
$routeProvider
.when('/search',
{
controller : 'MyController',
templateUrl : 'partials/search.html'
})
.when('/not-found/:className',
{
controller : 'MyController',
templateUrl : 'partials/not-found.html'
})
My index.html
<body ng-app="MyApp">
<ng-view></ng-view>
</body>
</html>
The problem is that the back button on my phone does not work.i.e it does not remember the history.
e.g If I go from search.html to not-found.html, when I press the back button on my phone, I expect it to come back to search.html instead it closes my app.
I looked and ionic forum and the suggest way to make back button work is to use ion-nav-view. If I replace ng-view with ion-nav-view, the search/not-found page are not rendering, I even tried adding the ion-view on the search/not-found html page.
1) Could you please suggest a way to get my back button working?
In order to achieve that, you actually need to capture the hardware back button pressed event and perform the navigation accordingly or You can use ion-nav-back-button..
Capture the hardware back button event :
$ionicPlatform.registerBackButtonAction(function () {
if (condition) {
navigator.app.exitApp();
} else {
// handle back action!
}
}, 100);
More Details can be found here
Using ion-nav-back-button
<ion-nav-bar>
<ion-nav-back-button class="button-clear">
<i class="ion-arrow-left-c"></i> Back
</ion-nav-back-button>
</ion-nav-bar>
More Details about this can be found here
registerBackButtonAction is already handled as part of ion-nav-back-button as part of the ng-click attribute within the ion-nav-back-button definition: buttonEle.setAttribute('ng-click', '$ionicGoBack()') , since $ionicGoBack executes $ionicHistory.goBack() which in turn handles the hardware back button. A simple change to use state configuration should work fine as below:
angular
.module('app', ['ionic'])
.config(function ($stateProvider, $urlRouterProvider) {
$stateProvider
.state('search', {
url: '/search',
controller : 'MyController',
templateUrl : 'partials/search.html'
})
.state('not-found', {
url: `/not-found/:className',
controller : 'MyController',
templateUrl : 'partials/not-found.html'
});
$urlRouterProvider.otherwise('/search');
});
HTML:
<body ng-app="app">
<ion-nav-bar>
<ion-nav-back-button></ion-nav-back-button>
</ion-nav-bar>
<ion-nav-view></ion-nav-view>
</body>
</html>
