UIRouter - Dynamically change ui-view attribute - javascript

I would like to dynamically change the ui-view attribute such as each time the attribute changes, the view changes too...
I use multiple views as follow:
$stateProvider.state('main',
{url: "/main",
views: {
'': { templateUrl: "partials/main", controller: "MainCtrl" },
'clients#main': {templateUrl: "partials/client-list", controller: "ClientListCtrl"},
'impexp#main': {templateUrl: "partials/imp-exp", controller: "ImpExpCtrl"}
}
}
);
In my MainCtrl I define a $scope variable as follow:
$scope.main_view = 'clients';
and my HTML/jade:
div(ng-attr-ui-view='{{ main_view }}'
The problem is that when I change dynamically $scope.main_view, my view doesn't change.
Is it possible to dynamically change a ui-view? if it is, how?

StateProvider (possibly app.js)
$stateProvider
.state('main', {
url: "/main",
templateUrl: "partials/main.html",
controller: 'MainCtrl'
})
.state('main.substate', {
url: "/", // Inherits /main from parent state
templateUrl: "partials/client-list.html",
controller: 'ClientListCtrl',
});
Any template will be loaded into <div ui-view>
HTML Example:
<!-- Add your site or application content here -->
<div ng-include="'../views/main-nav.html'" ng-controller="NavCtrl"></div>
<div id="main" ui-view=""></div><!-- end #main -->
<div ng-include="'../views/footer.html'"></div>
Events to trigger state change:
<a ui-sref="main.substate">Changes out template and controller</a>
<span ng-click="$state.go('main.substate')">Clicking this will change template</span>
Checkout the ui-router $state docs.

Nested states in Ui-Router with AngularJS

I would like to have a common state with all the common views like the header and the sidebar, and a template where I would like to load different views that can change when the state is changing.
I have an index HTML file like this:
...
<div ui-view="header"></div>
<div ui-view="sidebar"></div>
<div class="container">
<div class="wrapper">
<div ui-view="content"></div>
</div>
</div>
...
While the AngularJS config is something like this:
$stateProvider
.state('mainCommonState', {
url: '',
abstract: true,
views: {
header: {
templateUrl: 'app/common/header.html',
controller: 'headerCtrl',
controllerAs: 'vm'
},
sidebar: {
templateUrl: 'app/common/sidebar.html',
controller: 'sidebarCtrl',
controllerAs: 'vm'
},
content: {}
},
resolve: {
apiEnvironment: function ($q, environmentApiService) {
var deferred = $q.defer();
deferred.resolve(environmentApiService.getApiEnvironment());
return deferred.promise;
}
}
})
.state('first-page-content', {
url: '/first-page-content',
parent: 'mainCommonState',
views: {
content: {
templateUrl: 'app/components/first-page-content.html'
controller: 'firstPageCtrl',
controllerAs: 'vm'
}
}
})
.state('second-page-content', {
url: '/second-page-content',
parent: 'mainCommonState',
views: {
content: {
templateUrl: 'app/components/second-page-content.html'
controller: 'secondPageCtrl',
controllerAs: 'vm'
}
}
})
.state('third-page-content', {
url: '/third-page-content',
parent: 'mainCommonState',
views: {
content: {
templateUrl: 'app/components/third-page-content.html'
controller: 'thirdPageCtrl',
controllerAs: 'vm'
}
}
})
For some reason this is not working: I have an empty view instead of the 3 templates that I would like to show in the content ui-view.
If I define a template (even a blank template) inside the the abstract state, the view that is always showing is the one inside the abstract state mainCommonState.
Where am I wrong?
1st Edit: UPDATE Following the first answer
Following the suggestion from Chris T, I have updated my code, but there still something missing.
I have created a Plunker so you can help me fixing the issues.
2nd Edit
Following the suggestions from Chris T, I have updated the code using the absolute path for the content view and now the contents are switching correctly.
I have updated the Plunker accordingly to that and introduced a new level of nesting view (tabs in the first page), and I would like to have the first tab active when the first page content is loaded.
If I follow these solutions and set empty the url of the first page and set it to the first tab instead, this is not working.
Any suggestions?
Your views are targeting the wrong named ui-view.
.state('second-page-content', {
url: '/second-page-content',
parent: 'mainCommonState',
views: {
content: {
templateUrl: 'app/components/second-page-content.html'
controller: 'secondPageCtrl',
controllerAs: 'vm'
}
}
})
In this snippet, it targets the ui-view named content from the parent state which is mainCommonState. However, the content ui-view was not created in the mainCommonState. It was created in the root template.
Change your view declarations to target the view at the correct state, for example this targets the content view at the root state (which is named empty string):
.state('second-page-content', {
url: '/second-page-content',
parent: 'mainCommonState',
views: {
'content#': {
templateUrl: 'app/components/second-page-content.html'
controller: 'secondPageCtrl',
controllerAs: 'vm'
}
}
})
In ui-router 1.0 and higher you can also use absolute ui-view names by prefixing with an exclamation
.state('second-page-content', {
url: '/second-page-content',
parent: 'mainCommonState',
views: {
'!content': {
templateUrl: 'app/components/second-page-content.html'
controller: 'secondPageCtrl',
controllerAs: 'vm'
}
}
})

UI Router template is not injected but state changes Changes

I am trying to make a nested views, here is the plunker https://embed.plnkr.co/oRMnMW4QoWwhSkm9maHf/. The state changes but the template not changes.
Can anyone correct me what have I done wrong
Goto Link > Second Nested .
On Clicking the button , state changes successfully but the content is not injected. I want the link page content to be replaced by the second-nested content
Try to put abstract:true on the 'father' root like:
var routerApp = angular.module('routerApp', ['ui.router','ncy-angular-breadcrumb']);
routerApp.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/home/list');
$stateProvider
// HOME STATES AND NESTED VIEWS ========================================
.state('home', {
url: '/home',
abstract: true,
templateUrl: './partial-home.html'
})
// nested list with custom controller
.state('home.list', {
url: '/list',
templateUrl: './partial-home-list.html',
controller: function($scope) {
$scope.dogs = ['Bernese', 'Husky', 'Goldendoodle'];
}
})
.state('home.second', {
url: '/second',
templateUrl: './second.html',
});
});
routerApp.run(['$rootScope', '$state', function ($rootScope, $state) {
$rootScope.$on('$stateChangeStart', function (event, toState) {
console.log("state Change")
});
}]);
but Remember .. if you put abstract: true .. the url is not a real one .. it's a prefix .. or as i call it .. a father of other routing ..so you can not call it in the .otherwise()
And in your link (and routing) of the second view .. just remove the .list ... so like this:
.state('home.second', { //<-- HERE .. REMOVE THE .list
url: '/second',
templateUrl: './second.html',
});
and in the link:
// AND HERE ..
<a ui-sref="home.second" class="btn btn-danger">Second Nested</a>
Answer is pretty simple - you are initializing 3rd level of nesting states but in ./partial-home-list.html you've didn't add ui-view directive.
Add <ui-view></ui-view> in ./partial-home-list.html and you will see that it works as you defined.
If you want to display home.list.second as separate page then define second state like this
.state('home.second', {
url: '/home/list/second',
templateUrl: 'second.html',
});
Remember to update ui-sref to home.second on button

Just to get nested breadcrumb I have not "nice" solution but will work.
-- Partial home list html
<div ng-if="state.current.name != 'home.list.second'">
<ul>
<li ng-repeat="dog in dogs">{{ dog }}</li>
</ul>
<div ncy-breadcrumb></div>
<a ui-sref="home.list.second" class="btn btn-danger">Second Nested</a>
</div>
<ui-view></ui-view>
App js
// nested list with custom controller
.state('home.list', {
url: '/list',
templateUrl: 'partial-home-list.html',
controller: function($scope, $state) {
$scope.state = $state;
$scope.dogs = ['Bernese', 'Husky', 'Goldendoodle'];
}
})
.state('home.list.second', {
url: '/second',
templateUrl: 'second.html',
});

header hide for a particular page in my angular

I m working on angular project and my need is hide header block on login page only. I tried to hide header on login page. But it still doesn't work for me. Can you any one help me to hide it on login state.
Here my index html
<div ng-include src="'views/header.html'" ng-hide="$state.current.name === 'login'"></div>
<div class="">
<div ui-view></div>
</div>
Here my app.js
var app = angular.module('Qapp', ["ui.router", "ngRoute"])
app.config(function($stateProvider, $urlRouterProvider) {
//$urlRouterProvider.when('/dam', '/dam/overview');
$urlRouterProvider.otherwise('/login');
$stateProvider
.state('base', {
abstract: true,
url: '',
templateUrl: 'views/base.html'
})
.state('login', {
url: '/login',
parent: 'base',
templateUrl: 'views/login.html',
controller: 'LogCt'
})
.state('dam', {
url: '/dam',
parent: 'base',
templateUrl: 'views/dam.html',
controller: 'DamCt'
})
});
You don't have access to $state object directly on HTML. For get access to it you should put $state object with the $scope/$rootScope, You could do this in run block/controller & use $state.includes instead of $state.current.name
Markup
<div ng-include src="'views/header.html'" ng-hide="$state.includes('login')">
</div>
Code
app.run(function($state, $rootScope){
$rootScope.$state = $state;
})

Angular JS controller called twice (ng-controller)

I'm developping an ionic application and when using angular for login my controller is called twice,
I've looked through all the others similar questions but didn't find a solution .
The problem is even when I remove the ng-controller="LoginCtrl as lgnCtrl"
I get my controller called once but without two-way databinding.
here is my route file :
$stateProvider
.state('login', {
url: "/login",
views: {
'main': {
templateUrl: "app/user/loginView.html",
controller: "LoginCtrl",
controllerAs: "lgnCtrl"
}
}
})
$urlRouterProvider.otherwise('/login');
here is my controller
angular.module('starter.controllers')
.controller('LoginCtrl', LoginCtrl);
function LoginCtrl($state, $storage, $translate, $ionicPopup, LoginService, messageService) {
var lgnCtrl = this;
console.log("user dash 1zz");
return lgnCtrl;
}
and here is my views:
loginView.html :
<ion-view view-title="loginView" id="signinBlk">
<ion-content>
<div class="list list col span_1_of_2 " ng-controller="LoginCtrl as lgnCtrl">
</div>
</ion-content>
</ion-view>
index.html:
<body ng-app="starter">
<ion-nav-view name="main"></ion-nav-view>
</body>
if you already define your controller in route you dont need to define controller in html template remove the ng-controller attribute with value form html template then run it will run just once
Instead of having this
ng-controller="LoginCtrl as lgnCtrl"
in html, we can have this in the controller when the route is defined with a controller, for example in the controller, it will go like this
$routeProvider
.when("/", { templateUrl: "views/abc.html", controller: "LoginCtrl as lgnCtrl", caseInsensitiveMatch: true });
it worked like a charm
the functions in the controller are only called once.

angularjs ui router : nested views and nested states

I'm new to angular and I'm trying to understand nested views concept.
Based on the example provided in their documentation: https://github.com/angular-ui/ui-router/wiki/Multiple-Named-Views
//home.html
<body>
<div ui-view="header"></div>
<div ui-view="settings"></div>
<div ui-view="content"></div>
</body>
I have settings.html which has a check box. If it's checked it will load in the view(not named) the advanced settings template if not it will load the basic template
//settings.html
<input type="checkbox" ng-change="change()" ng-model="advancedSettings" />
<div ui-view></div>
so far I have defined something like this:
$stateProvider
.state('home', {
views: {
'header': {},
'settings': {
templateUrl: 'settings.html'
},
'content': {},
}
})
since I have 2 templates basicSettings.html and advancedSettings.html that I need to load in the view from settings.html based on that checkbox, I thought I have to declare something like this:
.state('settings#home.basic',(){
templateUrl: 'basicSettings.html'
});
but it's not working, instead I receive a lot of errors on console. How is the best way to implement this, without removing names from homepage views(header,settings,content), also how do I change the view based on the check box?
Thanks
There is a working plunker
Solution here could be with states defined like this:
$stateProvider
.state('home', {
abstract: true,
url: "/home",
views: {
'header': {
template: "This is HEADER"
},
'settings': {
templateUrl: 'settings.html',
controller: 'HomeCtrl',
},
'content': {
template: "This is CONTENT"
},
}
})
.state('home.basic', {
url: "/basic",
templateUrl: 'basicSettings.html'
})
.state('home.advanced', {
url: "/advanced",
templateUrl: 'advancedSettings.html'
})
we have parent state "home" and two children. These are triggered on change by 'HomeCtrl', e.g. like this:
.controller('HomeCtrl', ['$scope', '$state',
function($scope, $state) {
$scope.advancedSettings = false;
$scope.change = function(){
var childState = $scope.advancedSettings
? "home.advanced"
: "home.basic";
$state.go(childState);
}
}])
So, based on the setting, the view target "settings" and its ui-view="" (unnamed one) is filled with a child state - basic or advanced
