Here is the entrypoint of my angularjs application. What I'm trying to create is an modal with multiple views.
(function() {
'use strict';
angular
.module('app', ['ui.router', 'ui.bootstrap'])
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('modal', {
url: '/modal',
onEnter: ['$stateParams', '$state', '$modal', function ($stateParams, $state, $modal) {
$modal.open({
templateUrl: 'partials/modal.html',
backdrop: 'static'
});
}]
})
.state('modal.models', {
url: '/models',
templateUrl: 'partials/modal.models.html'
});
})
.run(function ($rootScope) {
$rootScope.$on("$stateChangeError", console.log.bind(console));
});
}());
and this is the main view
<!-- Modal -->
<div id="myModal">
<div class="modal-header">
<h2>Select your own car</h2>
</div>
<div class="modal-body">
<h4>Brands</h4>
<a ui-sref="modal.models">Models</a>
<div ui-view></div>
</div>
</div>
My problem is that when I click on the link ui-sref nothing happens. Why ui-router doesn't work inside a modal? I should pass in the second view that is the following named modal.models.html
<div>
<h1>Hello</h1>
</div>
For those like me that stumble along later, here's another path:
This plunker uses a simple CSS modal (rather than the fancy ui-bootstrap one) to accomplish the same end result --with the additional perk of 'sticky states' that persist underneath the modal interaction. Note that this supports substates within the modal in a uirouter-kosher way.
$stateProvider.state('modal', {
url: '/modal',
views: {
'modal': {
templateUrl: 'modal.html'
}
}
});
$stateProvider.state('modal.substate', {
url: '/substate',
template: '<h3>I\'m a substate in a modal'
});
(Credit to #christopherthielen for the example code.)
<script type="text/ng-template" id="modal.html">
<div class="modal-overlay fade">
<div class="modal-content">
<h2>Modal</h2>
This modal has a substate. <a ui-sref=".substate">Activate it</a>
<div ui-view></div>
<a ui-sref="app">Back to the app...</a>
</div>
</div>
</script>
In my own troubleshooting, the problem with the 'injected-onEnter' pattern detailed in the ui-router FAQ --which your code follows-- is that the ui-views within the injected template seem to be no longer visible/available to ui-router. Alas! Good thing there's not much required to simply roll-your-own modal window.

There is a following code snippet:
<my-header></my-header>
<div ng-switch="$ctrl.page">
<div ng-switch-when="1"><component1></component1></div>
<div ng-switch-when="2"><component2></component2></div>
<div ng-switch-when="3"><component3></component3></div>
</div>
I want that component myHeader would be constructed before ngSwitch directive takes an action. Now component1 is constructed before myHeader.
Routing represents following code:
$stateProvider
.state({
name: 'myApp',
url: '/',
component: 'loader',
})
.state({
name: 'myApp.pages',
url: 'pages/{id:int}',
component: 'loader'
});
$urlRouterProvider.otherwise('/pages/1');
You can achieve this by exposing your controller in the link function inside the myHeader directive.
With that, you can easily add variables to the controller and control the visibility of the ng-switch div with ng-if. Check the code snippet down here.
Ah, don't forget to add ng-cloak to the div containing the ng-switch directive.
angular
.module('app', [])
.controller('TestController', function($scope) {
this.page = 1;
})
.directive('myHeader', function () {
return {
link: function (scope, element, attrs) {
// With element.controller() we can reach the controller that is wrapping our directive. Then, we can simply set the headerIsLoaded variable to true.
element.controller().headerIsLoaded = true;
},
scope: true,
templateUrl: 'my-header.html'
}
});
<div ng-controller="TestController as ctrl">
<my-header></my-header>
<!-- Add a visual feedback so user knows the components are being loaded -->
<div ng-if="!ctrl.headerIsLoaded">
Loading...
</div>
<!-- If ctrl.headerIsLoaded is set to true, the ng-switch will appear -->
<div ng-if="ctrl.headerIsLoaded"
ng-cloak>
<div ng-switch="ctrl.page">
<div ng-switch-when="1">
Page 1
</div>
<div ng-switch-when="2">
Page 2
</div>
<div ng-switch-when="3">
Page 3
</div>
</div>
</div>
</div>
I am trying to navigate to another page by using the selected objectID.
Angular Routing,
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function($routeProvider){
$routeProvider.when('/',{
controller: 'BooksController',
templateUrl: 'views/books.html'
})
.when('/books/details/:id',{
controller: 'BooksController',
templateUrl: 'views/book_details.html'
})
});
Angular Controller:
var myApp = angular.module('myApp');
myApp.controller('BooksController', ['$scope', '$http', '$location', '$routeParams', function($scope, $http, $location, $routeParams){
console.log('BooksController loaded...');
// This To get request all the books: it works fine
$scope.getBooks = function(){
$http.get('/api/books').then(function(response){
$scope.books = response.data;
});
}
// This to get request a book with specific id it works fine
$scope.getBook = function(){
var id = $routeParams.id;
$http.get('/api/books/'+id).then(function(response){
$scope.book = response.data;
});
}
}]);
And then I have this html page which work also fine accept the button in the page, this button supposed to give me a clean templateUrl to navigate to another html page but it give me weird URL:
<div class="panel panel-default" ng-init="getBooks()">
<div class="panel-heading">
<h3 class="panel-title">Latest Books</h3>
</div>
<div class="panel-body">
<div class="row">
<div ng-repeat="book in books">
<div class="col-md-6">
<div class="col-md-6">
<h4>{{book.title}}</h4>
<p>{{book.description}}</p>
<a class="btn btn-primary" href="#/books/details/{{book._id}}">View Details</a>
</div>
<div class="col-md-6">
<img class="thumbnail" src="{{book.image_url}}">
</div>
</div>
</div>
</div>
</div>
And once I press the button I'm supposed to get a clean url such as:
http://localhost:3000/#!/books/details/599701c1f3da51117535b9ab
but instead I get this url!
http://localhost:3000/#!/#%2Fbooks%2Fdetails%2F599701c1f3da51117535b9ab
Seems like you have hashprefix !, then your URL should also have ! after hash(#)
href="#!/books/details/{{book._id}}"
Since Angular 1.6 hashprefix is defaulted to !, you can disable this behavior by setting hashPrefix to ''(blank).
.config(['$locationProvider',
function($locationProvider) {
$locationProvider.hashPrefix('');
}
]);
Its because your url is getting converted into codes. %2f means a /.
You need to have this configuration to avoid this behavior of angular
myApp.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
You have Prefix in url which is converting into character i.e url encoding.
So you need to fix $locationProvider's hashPrefix property by replacing its value with empty/blank string
$locationProvider.hashPrefix('');
i have a weird bug in my angular app where the data in my ng-repeat is not displaying but if i refresh the page and navigate to my home page it quickly flickers into view then disappears, im not sure why this is happening can someone help me out?
thanks in advance

You are using jQuery ajax. Angular does not automatically update variable when modified outside the Angular scope (in this case, $scope.characters is modified using jquery ajax);
I sugges you use the $http service provided by angular for making ajax calls.
But if you insist in using jquery ajax, you can wrap this code $scope.characters = response.data.results; with
`$scope.$apply(function(){
})`
Result:
$scope.$apply(function(){
$scope.characters = response.data.results;
})
Here is the highlevel skeleton of my Angular SPA. My application is about college degree offerings. In that engineering page has a separate left nav which is currently built on ng-switch which i want to convert as route. How do i do that just using angular's native routing angular-route.js?
**app.js**
(function(){
var app=angular.module("myCollege",['ngRoute']);
app.config(['$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 $location.path() variable to know which view to display.
As I said this is not a good practice, because your controller isn't suppose to deal with routes.
would anyone be able to help me on this issue I am having?
I have a NavCtrl for manage my active tag, I was able to change the active tab when click on the menu item, however when I click on the link in the body views, it take me to the page I want to, but the active tag is not change.
//controller for nevigation menu
sp.controller('NavCtrl', ['$scope', 'auth', '$window','$rootScope', function ($scope, auth, $window,$rootScope) {
$scope.LogOut = auth.logOut;
$scope.isLoggedIn = auth.isLoggedIn;
$scope.tab = $rootScope.navTav;
$scope.toTop = function(){
$window.scrollTo(0, 0);
};
}]);
I try to use the $rootScope to set the navTab, but it's still not working
//setting root scope
sp.run(function($rootScope) {
$rootScope.navTav = 1;
})
ui-Router
.state('qaanswer', {
url: '/qa/{quesId}',
views: {
view50': {
templateUrl: './qa/qaanswer.html',
controller: 'QAAnswerCtrl'
},
'view60': {
templateUrl: './shareviews/activityupdates.html',
controller: 'HomeCtrl'
}
},
onEnter:['$rootScope',function($rootScope){
$rootScope.navTav = 5;
}]
Thank you so much for the help
Update HTML :
<body ng-controller="NavCtrl">
<!-- Desktop Menu -->
<div>
<div>
<ul>
<a href="#/home" ng-class="{active: navTab === 1}" ng-click="navTab = 1">
<li>Home</li>
</a>
<a href="#/qa" ng-class="{active: navTab === 2}" ng-click="navTab = 2">
<li>QA</li>
</a>
</ul>
</div>
</div>
<div>
<div>
<div class="row">
<div ui-view="view50"></div>
<div ui-view="view60"></div>
</div>
</div>
</div>
</body>
Working plunker
You can simplify your implementation and have no issues. Simply use the $rootScope variable directly in your template along side ng-class like so:
<body ng-controller="NavCtrl">
<a ng-class="{red: $root.navTab===0}" ui-sref="first">first</a>
<a ng-class="{red: $root.navTab===1}" ui-sref="second">second</a>
<div ui-view></div>
</body>
Then update $rootScope in your controllers.
.controller('NavCtrl', function($scope, $rootScope) {});
.controller('FirstCtrl', function($scope, $rootScope) {
$rootScope.navTab = 0;
});
.controller('SecondCtrl', function($scope, $rootScope) {
$rootScope.navTab = 1;
});
Your states get to stay relatively simple:
.state('first', {
url: '/first',
templateUrl: 'first.html',
controller: 'FirstCtrl'
})
.state('second', {
url: '/second',
templateUrl: 'second.html',
controller: 'SecondCtrl'
})
plunker
Ideally you would make a directive for such a task, and avoid using $rootScope. A simple way to do this is to broadcast a message whenever you land on a new page, then listen on that event in your tab directive and flip the correct tab as active.
