how to setup ui-router nested views - angularjs

I am trying to setup my app with ui-router. I am familiar with basic nested views but I am wanting to do something more complex. I have my basic setup for the main views. I would like to have a chat popup that has its own views that are independent from the main views. I want to be able to navigate the main views and not affect the states in the chat popup. So how is this done? Do i need to have a abstract state for the chat? and then have nested views from there?
here is a visual.
and here is a plunker
plunker
$stateProvider
.state('root', {
abstract: true,
views: {
'#': {
template: '<ui-view />',
controller: 'RootCtrl',
controllerAs: 'rootCtrl'
},
'header#': {
templateUrl: 'header.html',
controller: 'HeaderCtrl',
controllerAs: 'headerCtrl'
},
'footer#': {
templateUrl: 'footer.html',
controller: 'FooterCtrl',
controllerAs: 'footerCtrl'
}
}
})
.state('root.home',{
parent:'root',
url:'/home',
templateUrl:'home.html',
controller: 'HomeController',
controllerAs:'homeCtrl'
})
.state('root.about',{
parent:'root',
url:'/about',
templateUrl:'about.html'
});
});

I suggest that, don't use footer as a ui-view, because it is completely independent of your states.
Then how?
Make your footer part as a template and use ng-include to render your footer part.
<footer ng-include="'/footer.html'"></footer>
And within footer.html you can specifies the controller for the footer view.
Benefits
No need to handle footer on each state
No need to pass chat history on every change in state.

Create Chat service/function with controllers in different js files and inject to the index.html and script.js. use bootstrap collapsible modal for pop-up chats.
Looking # your plunkr, you're on right track,though injecting controller from script.js via controllerAs is not scalable for larger app.
Instead you can create js files for each controller and service and separate partial views, just need to inject the services and controllers to index.html and mention partial views in stateprovider function.

I am not sure if You want to use route for the chat but there are two ways for you may be more
Use modals that can collabse and open when clicked like that of facebook here
Modals for bootstrap
Use angulars ngHide ngShow
For your navigation while using at sub elements on chat you can create one state for the chat and nest chat navigation in to you chat state so that any state change will not change your other chat states.
That means you will need to use substate concepts of ui-router

Multiple named views with dynamic routing in angularjs

Edit: Here is the complete code at Plunker. Though I can not c anything in execution but same code working at local. However gives a console error though
It all works perfect. But due to :id in /news/:id/, i am getting jquery/angular errors in console which can not be tracked anywhere in my code
I can not c What i am doing wrong.
Edit: Solved plunker https://plnkr.co/edit/FWcuBgGpVdMj3CroFrYJ
First of all you are trying to use ui-router but you're including ngRoute script in your plunker. Change it to
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.3.1/angular-ui-router.min.js"></script>
Then everything should work fine!
I suggest you a few changes...
1. Use ui-sref instead of href because it's much easier to define
ui-sref="post({id:1})" which turns into href="#/news/1"
If you would like to change url some day, then you will have to just change your route file, not each href.
$stateProvider
.state('post', {
url: "news/:id"
or
$stateProvider
.state('post', {
url: "archive/:id"
or
$stateProvider
.state('post', {
url: "whatever/:id"
2. Use abstract state
In your example it's a way better to define abstract state which holds header, content and footer - it's a typical use case.
ui-router
Abstract States
An abstract state can have child states but can not get activated
itself. An 'abstract' state is simply a state that can't be
transitioned to. It is activated implicitly when one of its
descendants are activated.
Some examples of how you might use an abstract state are:
To prepend a url to all child state urls. To insert a template with
its own ui-view(s) that its child states will populate. Optionally
assign a controller to the template. The controller must pair to a
template. Additionally, inherit $scope objects down to children, just
understand that this happens via the view hierarchy, not the state
hierarchy. To provide resolved dependencies via resolve for use by
child states. To provide inherited custom data via data for use by
child states or an event listener. To run an onEnter or onExit
function that may modify the application in someway. Any combination
of the above. Remember: Abstract states still need their own
for their children to plug into. So if you are using an
abstract state just to prepend a url, set resolves/data, or run an
onEnter/Exit function, then you'll additionally need to set template:
"".
Here's a plunker which shows how I would do it.

Hope it helps.
Look at the documentation for ui router named views,
You can use following syntax for using multiple views
$stateProvider
.state('state',{
url: '',
views: {
'header': {
templateUrl: 'views/header.html',
controller: 'headerCtrl'
},
'content': {
template: '<div ui-view=" "></div>', //<-- child templates loaded to here
},
'footer': {
templateUrl: 'views/footer.html',
controller: 'footerCtrl'
}
}
})
.state('state.post', {
url: 'news/:id/:KeyWords'
templateUrl: 'views/post.html' //<-- This goes into content's ui-view
});
I'm guessing you want to keep the header and footer and change content views.
You can achieve this by making this state as parent to all other states
suppose
.state('main',{
abstract: true,
views: {
'header': ... ,
'content': {
template: '<ui-view></ui-view>',
}
'footer': ...
}
})
then all the child views will load their views in the ,
ex: in main.child etc, your template will load in the content's <ui-view></ui-view> tag
If you need to use a custom template depending on keywords you can do the following:
.config(['$routeProvider',
function($routeProvider, $routeParams) {
$routeProvider
.when('/news/:id/:keyWords', {
template: '<div ng-include="url"></div>',
controller: "exampleController"
})
then in the exampleController
function($routeParams, $scope) {
$scope.url = $routeParams.keyWords;
}

AngularJS view without controller

I creating a simple angularjs app. I've imported ngRoute module and 2 views - Home and Contact. Home view is defined with controller.
.when("/", {
templateUrl: "home/home.html",
controller: "HomeController"
})
I don't need to implement logic for Contact view, because there are only 1 form to contact with me, that can work very well without angular. Can I define a route view without controller? Like:
.when("/contact". {
templateUrl: "contact/contact.html"
})
Is controller obligatory?
No controller is not obligatory. You can define a route without it

render angular route inside another page

I am novice to angularjs. i want to know that is there any way to render html template based on route inside div of other page. let me explain with an example.
/Employee/Add is route which show a add.html template to add new employee.
can i render this add.html or /Employee/Add route in other 'abc.html' page ??. i know we can use ng-include directive to render any html template. but i am looking based on route.
is that possible ??
You can do this using UI-router. Your basically creating a child state. Common use case is to create Tabs within a page. It would look something like this:
.state('league.games', {
url: '/games',
views: {
'tabContent': {
templateUrl: 'app/games/games.html',
controller: 'GamesCtrl',
controllerAs: 'vm',
resolve: {
initialData: ['$stateParams', 'gamesInitialDataService',
function($stateParams, gamesInitialDataService) {
return gamesInitialDataService.getData($stateParams.leagueId);
}]
}
}
}
})

ionic/angularjs app construction

When making an ionic app what is the best method of creating different pages of information?
Right now I have separate html documents for each page and a button pointing to each html document; however, I feel like angular/ionic provides a better way of doing so that I missed. For example, the app I am making has a main page with buttons for 5 places. Each button loads a completely new html document with info about the place labeled on the button.
If it is too much to explain, a link answering what I am asking is fine
Thanks
What you want are angular templates. You can write a template once, and then pass in information from the controller to take the place of the angular bindings. You have one master template, that changes the angular bindings depending on which information you pass it in the controller.
For example, you could have your application load in partial templates for each location, and display them all on your main page without having to hit a new html document. Check out the example in the Angular Tutorial.
And the Live Demo
You can do it by uiROUTER, For example: angular.module('ionicApp', ['ionic']) .config(function ($stateProvider, $urlRouterProvider) { $stateProvider .state('menu', { abstract: 'true', templateUrl: 'templates/menu.html', controller: 'MenuCtrl' }) / ... / .state('menu.work', { url: '/work', views: { menuContent: { templateUrl: 'templates/work.html', controller: 'WorkCtrl' } } }); $urlRouterProvider.otherwise('/work'); });

Displaying separate data from API in different places on page in Angular

I have a SPA that will display data from an API in two separate parts of the page. One section displays products and prices. This information will remain on the page. The other section is a basic CRUD view. It allows the user to create new selections, read their selections, edit their selections, and remove their selections. I'm trying to determine the best way to display these two views. The CRUD section uses ng-view. Should the price/product section use a directive, a separate controller, or should I break up the page into two modules?
I'm new to Angular, and want to make sure that I do things right to avoid unforeseen issues down the road.
HTML:
<div ng-view="">
<!--user selections go here -->
</div>
<!--Product/Price info will go here. Unsure whether to insert ng-app="new module", ng-controller="new controller", or a directive with its own element-->
Javascript for user selections view:
myApp.config(function ($routeProvider) {
$routeProvider
.when('/list', {
templateUrl: 'views/list.html',
controller: 'ProjectListCtrl as projectList'
})
.when('/edit/:projectId', {
templateUrl: 'views/detail.html',
controller: 'EditProjectCtrl as editProject'
})
.when('/new', {
templateUrl: 'views/detail.html',
controller: 'NewProjectCtrl as editProject'
})
.otherwise({
redirectTo: '/'
});
});
Factory for CRUD / user form section:
myApp.factory('Projects', function($firebase, fbURL) {
return $firebase(new Firebase(fbURL+'/projects')).$asArray();
});
Factory for product list/price section:
myApp.factory('Products', function($firebase, fbURL) {
return $firebase(new Firebase(fbURL + '/products')).$asArray();
});
The native Angular router is limited when creating complex and nested UIs, but AngularUI Router is a great alternative and very widely used. If you want to include multiple views in your interface then this is the way to go. It's not much more complicated than the native router but the wins are huge.
AngularUI Router is a routing framework for AngularJS, which allows you to organize the parts of your interface into a state machine. Unlike the $route service in the Angular ngRoute module, which is organized around URL routes, UI-Router is organized around states, which may optionally have routes, as well as other behavior, attached.
Here's a Plunker to demo your particular case: http://plnkr.co/edit/xZD47L?p=preview
With ui-router you can name views
<div ui-view="viewName"></div>
and include templates and controllers in the corresponding ui-router configuration
myApp.config(function($stateProvider, $urlRouterProvider) {
// For any unmatched url, redirect to /
$urlRouterProvider.otherwise("/");
$stateProvider
.state('home',{
url: "/",
// list your views
views: {
"viewName": {
templateUrl: "viewName.html" ,
controller: "viewNameCtrl"
}
}
})
});

I hope this helps.
