Ok so I am trying to combine both nested and multiple views with angular-ui-router.
I have the following HTML:
Index.html
<div ui-view="viewA"></div>
viewA.html
index.viewA
<div ui-view="viewANested"></div>
viewANested.html
index.viewA.nested
And the following javascript:
var myapp = angular.module('myapp', ["ui.router"])
myapp.config(function($stateProvider){
$stateProvider
.state('index', {
url: "",
views: {
"viewA": {
templateUrl: "viewA.html",
views: {
"viewANested":{
templateUrl: "viewANested.html"
}
}
}
}
});
})
A plunker is here, I am trying to combine both multiple and nested views but it isn't working for me. I can see the outer view just fine but no joy in the inner one, with no errors in the console.
For the sake of simplicity I have removed the multiple views from the example, but the HTML/Javascript wouldn't change in structure if they were there.
I have tried this javascript also:
myapp.config(function($stateProvider){
$stateProvider
.state('index', {
url: "",
views: {
"viewA": {
templateUrl: "viewA.html",
}
"viewANested": {
templateUrl: "viewANested.html",
}
}
});
})
This isn't working either (combined with changing the ui-view property to 'viewA.Nested'):
myapp.config(function($stateProvider){
$stateProvider
.state('index', {
url: "",
views: {
"viewA": {
templateUrl: "viewA.html"
},
"viewA.Nested":{
templateUrl: "viewANested.html"
}
}
});
})
Still no joy, I can't think of any other way to do this, can somebody shed some light on where I am going wrong?
Am I making a mistake or is this a limitation of the framework itself?
I think the alternative is to have a flatter structure, and extra mostly unused divs on my index page that I can use if neccessary to put content into for more complex pages, is that the way to go? It seems a bit hacky.
Thanks
You are almost there. With ui-router we can have many/nested views defined for one state. The updated plunker is here. I've used your last attempt, and this is the only change I made:
$stateProvider
.state('index', {
url: "",
views: {
"viewA": {
templateUrl: "viewA.html"
},
// "viewA.Nested":{
"viewANested#index":{
templateUrl: "viewANested.html"
}
}
});
As we can see, instead of name "viewA.Nested" I used this: "viewANested#index"
The most important part is the delimiter # followed by state name index - which is the target where is the view name viewANested searched for.

I want to be able to click on the anchor in the #leftDiv and make the UI router template open in the #rightDiv. So, when I click on Hello Plunker 1 in the #leftDiv, I want peopleOne.html to open in the #rightDiv. When I click on Hello Plunker 2, I want peopleTwo.html to replace peopleOne.html in the #rightDiv.
Here is a Plunker - https://plnkr.co/edit/T8RTgea8VccA9mdBABGC?p=preview
Can someone provide insight into why this is not working.
Script.js
var Delivery = angular.module('Delivery', ['ui.router']);
angular
.module('Delivery')
.config(function($stateProvider, $locationProvider) {
$locationProvider.hashPrefix('');
$stateProvider
.state('home', {
url: '/Delivery',
views: {
'view': {
templateUrl: 'Delivery.html',
},
},
})
.state('peopleOne', {
url: '/peopleOne',
parent: 'home',
views: {
'view#': {
templateUrl: 'peopleOne.html'
}
},
})
.state('peopleTwo', {
url: '/peopleTwo',
parent: 'home',
views: {
'view#': {
templateUrl: 'peopleTwo.html'
}
},
})
})
A few problems I've noticed:
First, put a console.log after the $stateProvider configuration calls to setup your routes. You will see that this code is never even called. Your angular app is not quite set up properly. You are using dat-ng-app in the index template, when you should be using ng-app. Otherwise angular is never actually used.
The next issue is in your $stateProvider configuration. I am not sure which documentation you are following, but your configurations for the states should look something like this:
# Set the default state
$urlRouterProvider.otherwise('/home')
# Configures home, peopleOne, and peopleTwo states
$stateProvider
.state('home', {
url: '/home',
templateUrl: 'home.html'
})
.state('peopleOne', {
url: '/peopleOne',
templateUrl: 'peopleOne.html',
parent: 'home'
})
.state('peopleTwo', {
url: '/peopleTwo',
templateUrl: 'peopleTwo.html',
parent: 'home'
})
Finally, when actually creating the links in your template, I find it easier to use the ui-sref tag, which allows you to create a link based on a state name. So a link to the peopleOne state would look like this: <a ui-sref="peopleOne"></a>.
I've attached a plunker based off your original code
https://plnkr.co/edit/NazuoFoDOa3VGR6smoyH
I have a route definition as follows:
$stateProvider
.state('vehicles', {
url: '/vehicles',
templateUrl: 'foo/bar1.html'
}).state('vehicles.id', {
url: '/{id}',
templateUrl: 'foo/bar3.html'
}).state('vehicles.create', {
url: '/create',
templateUrl: 'foo/bar2.html',
controller: 'VehicleCreateController'
});
I have a button that does
$state.go("vehicles.create");
The problem is, that while the URL changes correctly, the page remains the same. Only after the second click, the correct template appears.
After a hint from my colleague I realized, that it was the state definitions that caused the problem. Reordering the states from "more specific" (URL-wise - i.e. /create) to less specific (/{id}) did the trick. So the thing that was wrong was having the more generic URL /vehicles/{id} before the very similar, but less generic /vehicles/create.
So here's the improved version:
$stateProvider
.state('vehicles', {
url: '/vehicles',
templateUrl: 'foo/bar1.html'
}).state('vehicles.create', {
url: '/create',
templateUrl: 'foo/bar2.html',
controller: 'VehicleCreateController'
}).state('vehicles.id', {
url: '/{id}',
templateUrl: 'foo/bar3.html'
});
use : for your params and ? to make those params optional if you need.
check the below code snippet, for routing with params.
$stateProvider
.state('contacts.detail', {
url: "/contacts/:contactId",
templateUrl: 'contacts.detail.html',
controller: function ($stateParams) {
// If we got here from a url of /contacts/42
expect($stateParams).toBe({contactId: "42"});
}
})
check this for more clear view on routing.
I am creating a web app to help students in science, history and math. When you first land on the site I have a home/landing page. When you click get started I route to /exam/instructions. Each of my steps instructions, math and science our templates that I load into the ui-view="exam-detail". Currently the whole ui-view loads when I navigate to and from instructions through sciences. Ideally I simply want an area for pagination and an area for the subject matter and only want the ui-view="exam-detail" to update with the correct template.
I have not used UI-Router at all and any assistance would be greatly appreciated.
index.html
<div ui-view></div>
state-exam>exam.html
<div class="state-exam">
<nav ui-view="exam-pagination"></nav>
<section ui-view="exam-detail"></section>
</div>
route.js
(function() {
'use strict';
angular
.module('studentPortal')
.config(routeConfig);
function routeConfig($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/',
templateUrl: 'app/main/main.html',
controller: 'MainController',
controllerAs: 'main'
})
.state('exam', {
url: '/exam/:step',
abstract: true,
templateUrl: 'app/state-exam/exam.html',
controller: 'ExamController',
controllerAs: 'examController',
})
.state('exam.instructions', {
url: '/instructions',
views: {
'exam-pagination':{
templateUrl: 'app/state-exam/exam-pagination.html'
},
'exam-detail' : {
templateUrl: 'app/state-exam/exam-instructions.html'
}
}
})
.state('exam.math', {
url: '/math',
views: {
'exam-pagination':{
templateUrl: 'app/state-exam/exam-pagination.html'
},
'exam-detail' : {
templateUrl: 'app/state-exam/exam-math.html'
}
}
});
$urlRouterProvider.otherwise('/');
}
})();
There is a working plunker
There is a similar Q & A in fact, with working plunker:
Angular UI Router - Nested States with multiple layouts
Solution here, is to move the static view from child to parent. It won't be reloaded for each child (view is reloaded only if parent state is changed). We will use absolute naming (see included links for more details)
So this is the code adjustment
.state('exam', {
url: '/exam/:step',
abstract: true,
// the root view and the static pagination view
// will be defined here, so we need views : {}
views: {
'':{
templateUrl: 'app/state-exam/exam.html',
controller: 'ExamController',
controllerAs: 'examController',
},
// absolute naming targets the view defined above
'exam-pagination#exam':{
templateUrl: 'app/state-exam/exam-pagination.html'
},
}
})
.state('exam.instructions', {
url: '/instructions',
views: {
// 'exam-pagination':{}, // defined in parent
'exam-detail' : {
templateUrl: 'app/state-exam/exam-instructions.html'
}
}
})
.state('exam.math', {
url: '/math',
views: {
// 'exam-pagination':{}, // defined in parent
'exam-detail' : {
templateUrl: 'app/state-exam/exam-math.html'
}
}
});

Angular UI router nested views
Angular-UI Router: Nested Views Not Working
The working example is here
I am a novice with Angular and just getting to grips with the AngularUI Router framework. I have one html page which contains a list of questions (each question needs its own url) and a results page.
I have created a quick stripped down plunker (with all files) to demo the issue:
http://plnkr.co/edit/QErnkddmWB0JgendbOiV?p=preview
For SO ref:
app.js
angular.module('foo', ['ui.router'])
.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/q1');
$stateProvider
.state('question', {
url: '/:questionID',
templateUrl: 'questions.html',
controller: 'questionsCtrl'
})
.state('results', {
url: '/results',
templateUrl: 'results.html'
})
})
.controller('questionsCtrl', function($scope, $stateParams) {
$scope.questionID = $stateParams.questionID;
$scope.scotches = [
{
name: 'Macallan 12',
price: 50
},
{
name: 'Chivas Regal Royal Salute',
price: 10000
}
];
});
Basically for some unknown reason (to me) I have to click the 'results' link twice for it to appear in my eyes should appear on the first click.
Does anyone know why this is happening?
A.
What we should do is to reverse the state defintion:
.state('results', {
url: '/results',
templateUrl: 'results.html'
})
.state('question', {
url: '/:questionID',
templateUrl: 'questions.html',
controller: 'questionsCtrl'
})
The reason why?
because the question state definition is covering also the /results as a param /:questionID
But in general, this is still confusing, so I would distinguish the url more, e.g. with /question keyword
.state('results', {
url: '/results',
})
.state('question', {
url: '/question/:questionID',
...
})
edit: Based on the answer by #actor2019 I want to update my question to better explain the problem:
Using Angular UI-Router(v0.0.2), I've setup the app to properly navigate between main "pages"/state, while inheriting the base state.
Index.html:
<div ui-view></div>
base.html:
<!-- Header -->
<div>
<!-- Header markup -->
<!-- Search View -->
<div ui-view="search"></div>
</div>
<!-- Page Content view -->
<div ui-view></div>
The issue is here in the app.js file. When I add the views parameter to the base state, everything stops working(100% blank page). Without that parameter, the page renders correctly, but I have no search view.
app.js:
$urlRouterProvider.otherwise('/');
//
// Now set up the states
$stateProvider
.state('base', {
abstract: true,
templateUrl: 'views/base.html',
views: {
"search": {
templateUrl: "views/search.html"
}
}
})
.state('base.home', {
url: "/",
templateUrl: "views/home.html"
})
.state('base.page2', {
url: "/page2",
templateUrl: "views/page2.html"
});
How do I add views to this parent 'base' state?
UPDATE:
The problem with #actor2019's answer here is that the search view gets reinitialized when the state changes. I'd like the views off the base level to persist through state changes.
The first obvious mistake:
You can't specify controller and template on the state while your using views. They are mutually exclusive...
This is because when there is no "views" but a controller and template on the state, UI-Router automatically creates the "views" property and pulls those properties to an "empty" view...
.state('base', {
abstract: true,
templateUrl: 'views/base.html', //Can't do this
views: { // when this is there.
"search": {
templateUrl: "views/search.html"
}
}
})
Instead do:
.state('base', {
abstract: true,
views: {
"": {
templateUrl: 'views/base.html'
},
"search": {
templateUrl: "views/search.html"
}
}
})
Second problem:
How views targeting works with nested views etc. is not very logical, it may work well if you restrict your self to one view in one view all the way down, but ones you start working with multiple named views it all gets confusing... Add unnamed views on top and many people gets lost...
The way views work in UI-Router is the worst part of UI-Router...
Given you example I am not even entirely sure of the way to target the search view from your abstract parent state... Might be:
.state('base', {
abstract: true,
views: {
"": {
templateUrl: 'views/base.html'
},
"search#base": {
templateUrl: "views/search.html"
}
}
})
If it can even be made to work... Alternatively you can move the search view out of base.html, but I guess you added it in there for a reason.
The whole view concept is the biggest reason why I ended up writing https://github.com/dotJEM/angular-routing instead.
The Child state should be home.search instead of header.search. In your case, you may want to write some abstract state to hold the layout,
base.html
<div class="row-fluid">
<div class="header">
<div class="span3" ui-view="logo"></div>
<div class="span9" ui-view="menu"></div>
</div>
</div>
<div class="row-fluid">
<div class="content">
<div class="span2" ui-view="sidebar"></div>
<div class="span10" ui-view="entry"></div>
</div>
</div>
in app.js
$stateProvider
.state('base',{
abstract:true,
url:'/',
templateUrl: viewBase+'base.html'
})
.state('base.main',{
url:'',
views:{
"logo":{
templateUrl:viewBase+'main/logo.html'
},
"menu":{
templateUrl:viewBase+'main/menu.html'
},
"sidebar":{
templateUrl:viewBase+'main/sidebar.html'
},
"entry":{
templateUrl: viewBase+'main/entry.html'
}
}})
According to the ui-router documentation, when the application is in a particular state—when a state is "active"—all of its ancestor states are implicitly active as well. So, for example, when the "contacts.list" state is active, the "contacts" state is implicitly active as well, because it's the parent state to "contacts.list". Child states will load their templates into their parent's ui-view. I'd reccomend looking over the section of their documentation entitled Nested States & Views to gain a fuller understanding of how to do this.
In the code you have provided us here, the parent state of the search template is home, while
.state('header.search', {
templateUrl: "views/search.html",
controller: "SearchCtrl"
})
implies that the parent state of the search template should be header in order for the view to get loaded correctly. So, I believe the following changes to your app.js will fix your issue.
app.js
$stateProvider
.state('home', {
url: "/",
views: {
'': {
templateUrl: "views/mainContent.html",
controller: "MainCtrl"
},
'header': {
templateUrl: "views/header.html"
},
'footer': {
templateUrl: "views/footer.html"
},
}
})
.state('home.search', {
views: {
'search': {
templateUrl: "views/search.html",
controller: "SearchCtrl"
}
})
.state('anotherPage', {
url: "/anotherPage",
templateUrl: "views/anotherPage.html"
});
This works for me.
$stateProvider
.state('base', {
abstract: true,
url:'/',
templateUrl: 'views/base.html'
})
.state('base.home', {
url: "",
views: {
"search#base": {
templateUrl: "views/searchOfHome.html"
}
//content#base, contentOfHome.html
}
})
.state('base.page2', {
url: "page2",
views: {
"search#base": {
templateUrl: "views/searchOfPage2.html"
}
//content#base, contentOfPage2.html
});
If 'base' is the root state, you don't need the '#base'
