I have a simple angualr application which have dashboard that shows the different views of items. The /dasboard/:item is an abstract state. My valid urls are /dasboard/item0/view0, /dashboard/item1/view0, etc...
I want to track the current item and current view, without the additional code and only with the help of ui-router.state variable.
This part of script
<div class="">
you are looking at <strong>{{$state.current.name}}</strong> of {{$state.$current.params.item.value()}}
</div>
is printing the current item with the current view of it. This is printing the view correctly but not the item, for which I am referring the variable $state.$current.params.item.value() , the corresponding url in browser is changing the accordingly but not the text inside the div, I don't understand what I am doing wrong here.
I am expecting the value I clicked on, but instead of that, I always get the default value of parameter, which is item0.
Here is a stripped down version of my application.

</body>
</html>
$stateParams service must be specified as a state controller, and it will be scoped so only the relevant parameters defined in that state are available on the service object.
Since your dashboard.view0 has no params, it is not showing any when you print them.

I'm doing a tutorial from https://thinkster.io/tutorials/mean-stack called flapper news. I have completed the tutorial and the system work fine. But, I was thinking doing an inline template in a single file is not a good practice specially if you're doing a big project. So I tried to separate those templates into files(.html). Unfortunately the html file cannot be displayed in the ui-view. There was no error in the console nor the server. I tried to change my index.ejs file in the view folder into the public folder and rename it to index.html. Still not working.
Here is my index.html:
<html>
<head>
<title>Flapper News</title>
<link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css" rel="stylesheet">

<body ng-app="flapperNews">

<ul class="nav navbar-nav">
<li ng-show="isLoggedIn()"><a>{{ currentUser() }}</a></li>
<li ng-show="isLoggedIn()">Log Out</li>
<li ng-hide="isLoggedIn()">Log In</li>
<li ng-hide="isLoggedIn()">Register</li>

</nav>
<div class="row">
<div class="col-md-6 col-md-offset-3">

Here is one of the html file in the same public folder(home.html):
<script type="text/ng-template" id="/home.html">
<div class="page-header">

<div ng-repeat="post in posts | orderBy: '-upvotes'">

public/javascripts/angularApp.js:
var app = angular.module('flapperNews', ['ui.router']);
app.config([
'$stateProvider',
'$urlRouterProvider',
function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('home', {
url: '/',
templateUrl: 'home.html',
controller: 'MainCtrl',
resolve: {
postPromise: [
'posts',
function(posts) {
return posts.getAll();
}
]
}
})
.state('posts', {
url: '/posts/{id}',
templateUrl: '/posts.html',
controller: 'PostsCtrl',
resolve: {
post: [
'$stateParams',
'posts',
function($stateParams, posts) {
return posts.get($stateParams.id);
}

}
})
.state('login', {

templateUrl: '/login.html',

onEnter: ['$state', 'auth', function($state, auth) {
if (auth.isLoggedIn()) {
$state.go('home');
}
}]
});
$urlRouterProvider.otherwise('/');
}
]);
fyi, the ".state('home', { url:" was ".state('home', { url: '/home'" but it show an error so I change it to "url: '/'" and the error was gone. But still the ui-view cannot display the templates.
This is the output:
enter image description here
Anyone has any idea on how to solve this? Does bower has anything to do with this?
You don't need the script tag once you have the template on the separate file. Remove it and it should works. You can just use the path of the file for the templateURL then
Sometimes you will something like this just like you have,
<script type="text/ng-template" id="template.html">
... some template stuff
</script>
That script tag was actually for having the template on the same file as the main template file, and you can use templateUrl with the value of the id attribute just like usual. It will treat the body of the script tag as a file of template.html since the value of the id is template.html
I am using Angular 1.6.2 and UI Router. I am still trying to learn the concepts correctly, but have come to a road block.
I have a parent state called app using MainController, and a bunch of child states. However I now want to go one level deeper by making grandchild states.
The following codes leaves me with a blank page when loading www.example.com/manage-users/edit/1 thus not loading the grandparent state.
However it does work if I make app a parent of edit-users (the one I want to make a third level deep), but thats not really the correct way of going about it. Because after this I need to use the parent states for other reasons.
index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<base href="/">
// loading JS/CSS etc
</head>
<body ng-app="sampleApp">
<div class="container">
<div ui-view></div>
</div>
</body>
</html>
parent.html
<div ng-controller="MainController as data">
// more html
<div ui-view></div>
</div>
manage-users.html
<div class="col-sm-12" ng-controller="UserController as data">
// more html
<div ui-view></div>
</div>
manage-users-edit.html (only works when I make the parent state 'app' instead of 'manage-users'
<div>Hello World! This is the Edit HTML Page</div>
app.js setting up states
$stateProvider
.state('app', {
templateUrl: 'views/parent.html',
controller: 'MainController as data'
})
.state('manage-users', {
parent: 'app',
url: '/manage-users',
templateUrl: 'views/manage-users.html',
controller: 'MainController as main'
})
.state('edit-users', {
parent: 'manage-users',
url: '/manage-users/edit/:id',
templateUrl: 'views/manage-users-edit.html',
controller: 'MainController as main'
});
Try this:
index.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<base href="/">
// loading JS/CSS etc
</head>
<body ng-app="sampleApp">
<div class="container" ui-view="container"></div>
</body>
</html>
parent.html
<div ng-controller="MainController as data">
// more html
<div ui-view="parent"></div>
</div>
manage-users.html
<div class="col-sm-12" ng-controller="UserController as data">
// more html
<div ui-view="manageusers"></div>
</div>
app.js
$stateProvider
.state('app', {
views:{
'container': {
templateUrl: 'views/parent.html',
controller: 'MainController as data'
}
}
})
.state('app.manage-users', {
url: '/manage-users',
views:{
'parent':{
templateUrl: 'views/manage-users.html',
controller: 'MainController as main'
}
}
})
.state('app.manage-users.edit-users', {
url: '/edit/:id',
views:{
'manageusers':{
templateUrl: 'views/manage-users-edit.html',
controller: 'MainController as main'
}
}
});
You should always navigate to the child of your hierarchy. In this case, $state.go('app.manage-users.edit-users')
EDIT:
Your URL property in state config is wrong. To hit what you expect, you should enter http://exapmle.com/#/manage-users/edit/1.
I have updated the config, so extra manage-users from the URL is removed. Give it a shot.
I am making a simple Angular application that has an index.html which loads other HTML pages as views based on which navbar item selected; however, the routing is not working as expected. The main.html view is loaded fine, but none of the other views are loaded, and the URL is not what I expect.
The URL that shows up in the browser after an item is selected is localhost:8081/#!/#pageName. I do not know where the '!' is coming from, and there should not be a hash before the pageName. The URL that I am expecting is localhost:8081/#/pageName

Why are the other views not loading? Where is the exclamation point coming from in the URL? Why is there a hash before the pageName (I expect one hash, not two).
Why are the other views not loading?
The reason why your views are not loaded is because you hit the route. You use 1.6 angular and expect the behaviour from 1.5. There has been a change in location hash-prefix:
Due to aa077e8, the default hash-prefix used for $location hash-bang
URLs has changed from the empty string ('') to the bang ('!'). If your
application does not use HTML5 mode or is being run on browsers that
do not support HTML5 mode, and you have not specified your own
hash-prefix then client side URLs will now contain a ! prefix. For
example, rather than mydomain.com/#/a/b/c the URL will become
mydomain.com/#!/a/b/c.
If you actually want to have no hash-prefix, then you can restore the
previous behavior by adding a configuration block to you application:
appModule.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix(''); }]); Source
What to do?
1. Set HTML5mode true
$locationProvider.html5Mode(true);
and in html set base in html header:
<base href="/">
Lastly change <a ng-href="#pagename"> to
<a ng-href="pagename">
2. Go back to old behaviour from 1.5 - set hash prefix manually
This will make your app work as you expect in your question.
app.config(['$locationProvider', function($locationProvider) {
$locationProvider.hashPrefix('');
}]);
Why is there a hash before the pageName?
The way you link is treated as a hashtag anchor tag. Which will scroll down to the current div with the given id. If you fix your problem with one of the above reasons this will be fixed aswell.
I'm new to angular and trying to learn it, so I guess this is a pretty basic question,
I am trying to use ng-view, so far with no success.
this is my code:
HTML:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Hello world</title>
<script src="~/scripts/refernces/jquery-1.10.2.js"></script>

<body ng-app="myApp">

<li><a href='/#About'>About</a></li>
<li><a href='/#Contact'>Contact</a></li>
<li><a href='/#Other'>Other</a></li></ul></div</div></nav>"
<div ng-view></div>
</body>
JS:
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider.when("#About", {
template: '<h1>about</h1>'
})
.when("Contact",
{
template: '<h1>Contact</h1>'
});
});
I've tried declaring 'when' with and without the '#' sign, and I know Angular is loading fine (I have a controller that acts as I expect and I don't have any errors in the console) but I can't seem to make the routing work.
Tnx
If you set $locationProvider.html5Mode to true, you need to add:
<base href="/">
in the head of the document.
Also you do not need to use the hash in the href.
So give this code a try:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<base href="/">
<title>Hello world</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">

<script src="https://code.angularjs.org/1.4.9/angular-route.min.js"></script>
</head>
<body ng-app="myApp">
<nav class='navbar navbar-default'>

<div class='navbar-header'>
<a class='navbar-header' href='Home'>Demo Site</a>
</div>
<div>
<ul class='nav navbar-nav'>
<li class='active'><a href='Home'>Home</a></li>
<li><a href='/About'>About</a></li>
<li><a href='/Contact'>Contact</a></li>
<li><a href='/Other'>Other</a></li>
</ul>
</div
</div>
</nav>
<div ng-view></div>
<script>
var myApp = angular.module('myApp', ['ngRoute']);
myApp.config(function ($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider.when("/About", {
template: '<h1>about</h1>'
})
.when("/Contact",
{
template: '<h1>Contact</h1>'
});
});
</script>
</body>
You are actually pretty close, first off, one small typo in your html:
<<li><a href='/#Other'>Other</a></li></ul></div</div></nav>
^^^ missing end caret
Next up, we can talk about ngRoute's HTML5 mode. You explicitly set HTML5 mode to true, which means that angular is going to attempt to use all links you provide it as actual URLs, instead of append a URL fragment (#fake/url/here) to the current url and using that for routing. THe difference looks like this:
HTML5 mode == true
http://yoursite.com/angularPage/Contact
http://yoursite.com/angularPage/About
HTML5 mode == false
http://yoursite.com/angularPage#/Contact
http://yoursite.com/angularPage#/About
Looking at your HTML, I guessed that since you were using the # character, you did not want to use HTML5 mode, so I modified your stuff to look like this. Note how I changed the links, and your routeProvider.
<body ng-app="myApp">
<nav class='navbar navbar-default'>
<div class='container-fluid'>
<div class='navbar-header'>
<a class='navbar-header' href='Home'>Demo Site</a>
</div>
<div>
<ul class='nav navbar-nav'>
<li class='active'><a href='#Home'>Home</a></li>
<li><a href='#About'>About</a></li>
<li><a href='#Contact'>Contact</a></li>
<li><a href='#Other/Page'>Other</a></li></ul></div></div></nav>
<div ng-view></div>
</body>
JS
myApp.config(function ($routeProvider, $locationProvider) {
$locationProvider.html5Mode(false);
$routeProvider.when("/About", {
template: '<h1>about</h1>'
})
.when("/Contact",
{
template: '<h1>Contact</h1>'
})
.when("/Other/Page",
{
template: '<h1>OtherPage</h1>'
});
});
Check the fragment syntax, and not how the routeProvider essentially parses your #Other/Page into /Other/Page. Also note the lack of a / before the links in your <a> tags, a / there means an absolute link, which would replace your current navigation tree.
Is it possible to make something using 2 or more html files using ui-view? I need it to be something like this :
I've tryed to do something working on plinker, but looks like I clearly don't uderstand concepts. I've read a nested ui-vew tutorial but they simple make a single index.html and place multiple ui-view there, but I need multiple .html files.
test.html is just a file with some text that should be displayed under master header
index.html looks like this
<html ng-app="MyApp">
<head>
<link href="stylesheets/style.css" rel="stylesheet">
</head>
<body>
<h4>
This should be Master header
</h4>
<div ui-view></div>
<script data-require="angular.js#*" data-semver="1.3.0-beta.5" src="https://code.angularjs.org/1.3.0-beta.5/angular.js"></script>
<script data-require="ui-router#*" data-semver="0.2.10" src="https://rawgit.com/angular-ui/ui-router/0.2.10/release/angular-ui-router.js"></script>
<script src="app.js"></script>
<script src="controllers/main.js"></script>
</body>
</html>
this is app.html
<head>
<link href="stylesheets/style.css" rel="stylesheet">
</head>
<body>
<h4>
This should be Sub master header
</h4>
<div ui-view></div>
</body>
and app.js is written on pseudo code showing how I want it to work, because I clearly have no idea how to make it work
angular.module('MyApp', [
'ui.router'
])
.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('index', {
templateUrl: 'index.html',
controller: 'IndexCtrl'
})
.state('index.test', {
url: '/',
templateUrl: 'test.html',
controller: 'TestCtrl'
})
.state('app', {
templateUrl: 'app.html',
controller: 'AppController'
})
.state('app.test2', {
url: '/test2',
templateUrl: 'test2.html',
controller: 'Test2Controller'
})
})
test2.html is just a text.
I am not sure if I do understand your goal 100%, but there is updated plunker, showing how we can work with nested views.
Firstly, there is a $state defintion showing the nesting:
$stateProvider
.state('index', {
url: '/',
views: {
'#' : {
templateUrl: 'layout.html',
controller: 'IndexCtrl'
},
'top#index' : { templateUrl: 'tpl.top.html',},
'left#index' : { templateUrl: 'tpl.left.html',},
'main#index' : { templateUrl: 'tpl.main.html',},
},
})
.state('index.list', {
url: '/list',
templateUrl: 'list.html',
controller: 'ListCtrl'
})
.state('index.list.detail', {
url: '/:id',
views: {
'detail#index' : {
templateUrl: 'detail.html',
controller: 'DetailCtrl'
},
},
})
And here is the index core template layout.html:
<div>
<section class="top">
<div ui-view="top"></div>
</section>
<section class="middle">
<section class="left">
<div ui-view="left"></div>
</section>
<section class="main">
<div ui-view="main"></div>
</section>
</section>
</div>
And how it works?
I. List View
we can see the content of the tpl.top.html
<div>
This is a tpl.top.html<br />
<a ui-sref="index">index</a>
<a ui-sref="index.list">index.list</a><br />
</div>
which does have some navigation to the index or list view. The list view, will be injected into the tpl.left.html, which looks like this:
<div>
This is a tpl.left.html
<h4>place for list</h4>
<div ui-view=""></div>
</div>
Becuase the view target is unnamed <div ui-view=""></div>, we can defin list $state like this:
.state('index.list', {
url: '/list',
templateUrl: 'list.html',
controller: 'ListCtrl'
})
we can see, that we target the index (root) state view anchor, which is unnamed. But for a detail we do use different technique:
II. Detail View
This is the content of the tpl.main.html:
<div>
This is a tpl.main.html
<h4>place for detail</h4>
<div ui-view="detail"></div>
</div>
In this case, the anchor for a view is named: ui-view="detail", that is why we have to define that detail state like this:
.state('index.list.detail', {
url: '/:id',
views: {
'detail#index' : {
templateUrl: 'detail.html',
controller: 'DetailCtrl'
},
},
})
We can see, that because the parent view is not the target of our state (the grand parent index is the target) we have to use aboslute naming: 'detail#index'
III. View Names - Relative vs. Absolute Names
small cite from doc:
Behind the scenes, every view gets assigned an absolute name that follows a scheme of viewname#statename, where viewname is the name used in the view directive and state name is the state's absolute name, e.g. contact.item. You can also choose to write your view names in the absolute syntax.
SUMMARY:
So, this example is about it - about almost all essential features of the ui-router. We showed here how to use nesting, view naming (absolute/relative) and also how to use multiple views for one state (index state definition)
Please, observe that all in action here (click the inex.html in the top section, then try to select some details)
