Changing ui-views from other ui-views with Angular UI-router - html

I have a page with 2 ui-views, the top view has a form and some controls and the bottom view will be changed by the top view, but defaults to displaying a few tables.
I decided to try and do this initial page all in one state, and I am wondering if this is the correct way in this case. The state is called "tracker" and has the views with content as described above. When the user clicks a button in the top view, I want the bottom view to display alternate content (e.g. a map).
I can figure out how to change state "tracker" (views loaded with "controls.html" and "content.html") to a complete second state ("controls.html" and "map.html").
What I'm confused about is how would I change only the bottom view content#tracker between "contact.html" and "map.html" based on the button state in the top view.
The router is:
(function() {
'use strict';
angular.module('pb.tracker').config(function($stateProvider) {
$stateProvider.state('tracker', {
url: '/tracker',
controller: 'TrackerController as track',
data: {
pageTitle: 'Parcel Tracker',
access: 'public',
bodyClass: 'tracker'
},
views: {
'': {
templateUrl: 'modules/tracker/templates/tracker.html'
},
'controls#tracker': {
templateUrl: 'modules/tracker/templates/tracker-controls.html'
},
'content#tracker': {
templateUrl: 'modules/tracker/templates/tracker-details.html'
}
}
});
});
})();
and the base page's html is
<div class="container">
<div class="row spacer-top-xl">
<div class="col-md-12">
<div ui-view="controls"></div>
<div ui-view="content"></div>
</div>
</div>
</div>

One way out is using $broadcast and $on :
From the top view controller..
$scope.sendBroadcast = function() {
$rootScope.$broadcast('myAction');
}
and from the bottom view controller
$scope.$on('myAction', function() {
//Message received
});
another option may be using a service and $watch on a particular value for change.

angular-ui modal is not initially hidden

I'm following this angular recipes page for adding a modal dialog to my ui. It suggests the following markup, which I've added to one of my views.
... html for my view is here ...
<button class="btn" ng-click="open()">Open Modal</button>
<div modal="showModal" close="cancel()">
<div class="modal-header">
<h4>Modal Dialog</h4>
... etc, from the recipe doc
</div>
What I want to see is my view, plus an "Open Modal" button on the bottom and nothing else. What I see instead is the button and the content of the modal already visible on the page.
The very next words in the recipe doc are:
Note that even though we don’t specify it explicitly the modal dialog
is hidden initially via the modal attribute. The controller only
handles the button click and the showModal value used by the modal
attribute.
Why is my modal mark up initially visible on the page? I think I have installed angular-ui properly... in my index.html:
<script src="bower_components/angular-bootstrap/ui-bootstrap-tpls.js"></script>
And in my app JS:
angular.module('MonteAdmin', [
...
'ui.bootstrap',
...
])
That recipes page is likely out of date. At the time of the writing it might have been possible to pass a variable showModal to the modal directive to reveal or hide it. In your controller, you would have been able to show the modal by setting the scope variable showModal to true or false:
$scope.showModal = false;
$scope.open = function() {
$scope.showModal = true;
}
The current version does not work that way. You will have much better experience if you read the official documentation for the library at Angular UI Bootstrap
If you are using the latest version of the library, the directive is no longer modal but uib-modal. In addition, you have a bit more work to do to implement your modal.
Modal markup should be in a script tag, with a type set to text/ng-template as per the official example:
<script type="text/ng-template" id="stackedModal.html">
<div class="modal-header">
<h3 class="modal-title" id="modal-title-{{name}}">The {{name}} modal!</h3>
</div>
<div class="modal-body" id="modal-body-{{name}}">
Having multiple modals open at once is probably bad UX but it's technically possible.
</div>
</script>
To actually open the modal, your button click should trigger the following example function:
var modalInstance = $uibModal.open({
animation: $ctrl.animationsEnabled,
ariaLabelledBy: 'modal-title',
ariaDescribedBy: 'modal-body',
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
controllerAs: '$ctrl',
size: size,
appendTo: parentElem,
resolve: {
items: function () {
return $ctrl.items;
}
}
});
You must also define a controller for the modal, itself:
angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function ($uibModalInstance, items) {
var $ctrl = this;
$ctrl.items = items;
$ctrl.selected = {
item: $ctrl.items[0]
};
$ctrl.ok = function () {
$uibModalInstance.close($ctrl.selected.item);
};
$ctrl.cancel = function () {
$uibModalInstance.dismiss('cancel');
};
});
All of this code is found on the official documentation for Angular UI Bootstrap

Routing in Angularjs and express

I have created a plunker here with my code, which includes these routes.
'use strict';
var app = angular.module('app', ['ngResource', 'ui.router','ngAnimate', 'ui.bootstrap'])
.controller('Ctrl',function($scope,$log){
// controller code....
})
.config(['$urlRouterProvider','$stateProvider',function($urlRouterProvider,$stateProvider) {
$urlRouterProvider.otherwise('/login');
$stateProvider
.state('home', {
url:'/home',
templateUrl: '/views/home_page.html',
resolve: {
loggedin: checkLoggedin
}
})
.state('admin', {
url:'/admin',
templateUrl: 'views/admin.html',
resolve: {
loggedin: checkLoggedin
}
})
.state('login', {
url:'/login',
templateUrl: 'views/login.html',
});
}]) // end of config()
I am facing problem in routing. I have created login.html file , I am successfully logging in , after login it is redirecting to home_page.html , in this page I have created nav bar and few things. But if I click link admin from home page , it is showing only the admin page content , it is not showing nav bar in admin page. In index.html page I am using ui-view, but still it is not displaying home page's nav bar in other pages.
If I go to other pages other than home_page.html it is not showing nav bar.
If I write nav bar code in index.html then on the login screen also it will display nav bar. On login screen it should not display nav bar. please help me in solving this issue.
If you want to have the nav bar on every page after login, you must use nested views.
Mean, you define a "master" view where you have your nav-bar and define there a container, content (admin, main page) have to go in.
When I look at your source above, you not defined any nested view.
Good description and examples how to do this can be found here.
Cause the explanation would be to long for here, I provide the link.

How to pass data from one html page to another using ui.router in angularjs

I retrieve data from back-end and show it in a html page using a controller. When user click a certain link, the other page load according to the link id(here promo page). I want to pass the menu_id to the loading page. I use ngRoute. Below is the html code which I tried,
<li class="table-view-cell" ng-repeat="menu in menuList">
<a class="navigate-right btn-lg" href="#{{menu.link}}/{{menu_id}}">
<span class="{{menu.icon}}"></span>
{{menu.menuName}}
</a>
</li>
Below is the routing,
mobileApp.config(function($routeProvider) {
$routeProvider
.when('/promo/menu._id', {
templateUrl: 'tpl/promo.html',
controller: 'promoController',
activePage: 'promo'
})
Below is the controller for the promo page which I need to retrieve the menu_id,
$http.get(SERVER_URL + '/api/templates/getCategories?appId='+$rootScope.appId+'&mainId='+$routeParams.id)
.success(function(data) {
$scope.requestCategory = data[0];
}).error(function(err) {
alert('warning', "Unable to get templates", err.message);
});
mainModule.config([function($routeProvider) {
$routeProvider.when('/promo/:menu._Id', {
templateUrl : 'tpl/promo.html',
controller : 'promoController',
activePage: 'promo'
});
}
You can define your routing like above, notice the colon before menu._Id. In your controller, you can access menu._Id using $routeParams service as follows:
$routeParams.menu._Id
Thats's it.
It started to work when I changed the routing as below,
.when('/promo/:id', {
templateUrl: 'tpl/promo.html',
controller: 'promoController',
activePage: 'promo'
})
In that case you would have to do following in your controller:
$routeParams.id

Multiple UI-Views not working as expected

I am trying to use multiple UI-views in my AngularJS app and it is not working as expected. The app is a dashboard.
My directory structure is as follows:
index.html
app/
app.js
dashboard/
dashboard.html
dashboard.js
partials/
business.html
items.html
orders.html
sales.html
login/
login.html
login.js
The problem that I am having is that my index.html file has the following line of code:
<div ui-view></div>
The above line enables my application to show the login.html page and dashboard.html page. Now I want to be able to have partial views in my dashboard.html page and so I have also put the same line of code
<div ui-view></div>
in order to be able to embed partial views in my dashboard page. Instead of embedding though, the page instead just redirects. So for example if I am in my dashboard.html and click on a navigation item such as 'business', I am redirected to partials/business.html instead of the content being embedded.
1) Can I have multiple ui-views embedded within each other?
2) Am I correctly embedding the partial views?
I have scoured the internet but cannot find a solution. Thanks in advance for the help!
You can definitely have multiple embedded views.
Check out these AngularJS UI-Router tutorials: Nested Views and Multiple Named Views.
Let me know if you still have issues after looking them over.
You can define a ui-view inside another ui-view. I have implemented it in the following manner and its pretty straight forward.
Inside index.html I have code:
<div ui-view=""></div>
Then inside user.html I have code
<div ui-view=""></div>
And I have defined a config for displaying my views as
.config(function($urlRouterProvider, $stateProvider) {
var users = {
//Name must be in format Parent.Child
name: 'users',
url: '/user',
templateUrl: 'users/user.html',
controller: 'usersHandler',
data: {
pageTitle: 'Welcome to Users'
},
},
createUsers = {
name: 'users.createUsers',
url: '/createUser',
templateUrl: 'users/createUser.html',
data: {
pageTitle: 'Create Users'
}
},
listUsers = {
name: 'users.listUsers',
url: '/listUsers',
templateUrl: 'users/userLists.html',
data: {
pageTitle: 'Users listing'
}
},
getUserDealer = {
name: 'users.getUserDealer',
url: '/getUserDealer',
templateUrl: 'users/getUserDealer.html',
data: {
pageTitle: 'Users dealer listing'
}
},
editUser = {
name: 'users.editUser',
url: '/editUser',
templateUrl: 'users/editUser.html',
data: {
pageTitle: 'Edit User'
}
};
//Similarly define all the combination you want to separate
//add routes to stateProvider
$stateProvider
.state('users', users)
.state('users.createUsers', createUsers)
.state('users.listUsers', listUsers)
.state('users.getUserDealer', getUserDealer)
.state('users.editUser', editUser);
$urlRouterProvider.otherwise('/user/listUsers');
});
Whats happening is this that user.html is my parent file which is loaded inside index.html and editUser.html, getUserDealer.html and userLists.html etc are its children which I load within user.html using ui-view.
And I provide the links for nested pages as:
<ul class="nav navbar-nav">
<li>NEW USER</li>
<li>GET USER</li>
</ul>
This can be extended to additional parents and their children as per the need.
Hope it helps!!

Compiling dynamic HTML strings from database

The Situation
Nested within our Angular app is a directive called Page, backed by a controller, which contains a div with an ng-bind-html-unsafe attribute. This is assigned to a $scope var called 'pageContent'. This var gets assigned dynamically generated HTML from a database. When the user flips to the next page, a called to the DB is made, and the pageContent var is set to this new HTML, which gets rendered onscreen through ng-bind-html-unsafe. Here's the code:
Page directive
angular.module('myApp.directives')
.directive('myPage', function ($compile) {
return {
templateUrl: 'page.html',
restrict: 'E',
compile: function compile(element, attrs, transclude) {
// does nothing currently
return {
pre: function preLink(scope, element, attrs, controller) {
// does nothing currently
},
post: function postLink(scope, element, attrs, controller) {
// does nothing currently
}
}
}
};
});
Page directive's template ("page.html" from the templateUrl property above)
<div ng-controller="PageCtrl" >
...
<!-- dynamic page content written into the div below -->
<div ng-bind-html-unsafe="pageContent" >
...
</div>
Page controller
angular.module('myApp')
.controller('PageCtrl', function ($scope) {
$scope.pageContent = '';
$scope.$on( "receivedPageContent", function(event, args) {
console.log( 'new page content received after DB call' );
$scope.pageContent = args.htmlStrFromDB;
});
});
That works. We see the page's HTML from the DB rendered nicely in the browser. When the user flips to the next page, we see the next page's content, and so on. So far so good.
The Problem
The problem here is that we want to have interactive content inside of a page's content. For instance, the HTML may contain a thumbnail image where, when the user clicks on it, Angular should do something awesome, such as displaying a pop-up modal window. I've placed Angular method calls (ng-click) in the HTML strings in our database, but of course Angular isn't going to recognize either method calls or directives unless it somehow parses the HTML string, recognizes them and compiles them.
In our DB
Content for Page 1:
<p>Here's a cool pic of a lion. <img src="lion.png" ng-click="doSomethingAwesone('lion', 'showImage')" > Click on him to see a large image.</p>
Content for Page 2:
<p>Here's a snake. <img src="snake.png" ng-click="doSomethingAwesone('snake', 'playSound')" >Click to make him hiss.</p>
Back in the Page controller, we then add the corresponding $scope function:
Page controller
$scope.doSomethingAwesome = function( id, action ) {
console.log( "Going to do " + action + " with "+ id );
}
I can't figure out how to call that 'doSomethingAwesome' method from within the HTML string from the DB. I realize Angular has to parse the HTML string somehow, but how? I've read vague mumblings about the $compile service, and copied and pasted some examples, but nothing works. Also, most examples show dynamic content only getting set during the linking phase of the directive. We would want Page to stay alive throughout the life of the app. It constantly receives, compiles and displays new content as the user flips through pages.
In an abstract sense, I guess you could say we are trying to dynamically nest chunks of Angular within an Angular app, and need to be able to swap them in and out.
I've read various bits of Angular documentation multiple times, as well as all sorts of blog posts, and JS Fiddled with people's code. I don't know whether I'm completely misunderstanding Angular, or just missing something simple, or maybe I'm slow. In any case, I could use some advice.
ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

return {

scope.$watch(attrs.dynamic, function(html) {
ele.html(html);
$compile(ele.contents())(scope);
});
}
};
});
function MyController($scope) {
$scope.click = function(arg) {
alert('Clicked ' + arg);
}
$scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}
In angular 1.2.10 the line scope.$watch(attrs.dynamic, function(html) { was returning an invalid character error because it was trying to watch the value of attrs.dynamic which was html text.
I fixed that by fetching the attribute from the scope property
scope: { dynamic: '=dynamic'},
My example
angular.module('app')
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'dynamic' , function(html){
element.html(html);
$compile(element.contents())(scope);
});
}
};
});
Found in a google discussion group. Works for me.
var $injector = angular.injector(['ng', 'myApp']);
$injector.invoke(function($rootScope, $compile) {
$compile(element)($rootScope);
});
You can use
ng-bind-html https://docs.angularjs.org/api/ng/service/$sce
directive to bind html dynamically.
However you have to get the data via $sce service.
Please see the live demo at http://plnkr.co/edit/k4s3Bx
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope,$sce) {
$scope.getHtml=function(){
return $sce.trustAsHtml("<b>Hi Rupesh hi <u>dfdfdfdf</u>!</b>sdafsdfsdf<button>dfdfasdf</button>");
}
});
<body ng-controller="MainCtrl">
<span ng-bind-html="getHtml()"></span>
</body>
Try this below code for binding html through attr
.directive('dynamic', function ($compile) {
return {
restrict: 'A',
replace: true,
scope: { dynamic: '=dynamic'},
link: function postLink(scope, element, attrs) {
scope.$watch( 'attrs.dynamic' , function(html){
element.html(scope.dynamic);
$compile(element.contents())(scope);
});
}
};
});
Try this element.html(scope.dynamic);
than element.html(attr.dynamic);
