I have a map with markers on it. When you click a marker a child view opens with the marker details.
.state('map', {
url: '/map',
...
})
.state('map.detail', {
url: '/:markerId',
...
})
If you open a marker's details, navigate away from the map, then back to the map using ui-sref="map" the url will change to /map/<markerId> with the child view open.
I'd like to go straight to /map when clicking on ui-sref="map" but don't want to reload the 'map' just hide any child view.
Is there a simple way to do this? I've tried combinations of cache: false on the two states but that doesn't do what I want.
I am not fully sure, what is your issue. Because this
...I'd like to go straight to /map when clicking on ui-sref="map" but don't want to reload the map just hide any child view...
is the default behavior of UI-Router. There is a working plunker
These links, will not trigger RE-init of parent controller ('map' state)
<a ui-sref="map">
<a ui-sref="map.detail({markerId:1})">
<a ui-sref="map.detail({markerId:22})">
And states like this:
.state('map', {
url: "/map",
templateUrl: 'tpl.html',
controller: 'ParentCtrl',
})
.state('map.detail', {
url: "/:markerId",
templateUrl: 'child.html',
controller: 'ChildCtrl',
})
And both controllers:
.controller('ParentCtrl', ['$scope', function ($scope) {
$scope.timestamp = new Date().getTime();
}])
.controller('ChildCtrl', ['$scope', function ($scope) {
$scope.timestamp = new Date().getTime();
}])
And we can see, that 'map' state is still not changed

I am new to angular js and ui router. i am planning to design a angular js ui routed app. I have a two states, state A and State B. State B has child state.
on the landing page of the app (which is a query panel) state A is invoked correctly. Interaction with landing page should present the result which is routed as State B's child state.
app.js
$stateProvider
.state('A', {
url: '/queryPanel',
templateUrl: 'queryParameterView.html'
})
.state('B', {
url: '/resultPanel',
})
.state('B.child', {
url: '/overView',
templateUrl: 'xyz.html',
controller: function($scope) {
$scope.dogs = ['Bernese', 'Husky', 'Goldendoodle'];
}
});
so basically I want to transition from state A to State B's child states (i.e B.child)
<a ui-sref="B.child" class="btn btn-primary">show xyz</a>
This is how I am trying to invoke the child state.
However it isn't working. when I hit the button show xyz the url changes from
localhost:1234/queryPanel to localhost:1234/resultPanel/overView but the controller and template doesn't get invoked / loaded.
How should I go about solving this problem?. I am following this link
Thanks
Whenever you have a child states, you must make sure that in the parent state's view, it has a ui-view directive so that the child states can resides on it.
One immediate problem I can see with your $state configuration is that at your B state, you do not have a template or templateUrl property. What you should do is something like this:
$stateProvider
.state('A', {
url: '/queryPanel',
templateUrl: 'queryParameterView.html'
})
.state('B', {
url: '/resultPanel',
template:'<div ui-view></div>' // or you can use templateUrl
})
.state('B.child', {
url: '/overView',
templateUrl: 'xyz.html',
controller: function($scope) {
$scope.dogs = ['Bernese', 'Husky', 'Goldendoodle'];
}
});
Edit: Added plnkr
I want to temporarily change the browser url when the ui bootstrap modal is opened ( The page behind should remain as is, only the url changes ). When the modal is closed the url should be reverted back to the original one.
Steps :
User loads the page
url : xyz.com/home
User clicks a link opens a modal
url : xyz.com/detail/123
possible solution : changing url with html5 push state
problem : Angular ui-router tries to run its routes as per the changed url, eventually changing the background page.
User closes the modal
url : xyz.com/home
possible solution : html5 pop state
problem : Reloads the background page, which kills the purpose
Example implementation : Pinterest pins and their pin details popup.
You can use ui-router-extras sticky state to solve your problem. There is simple example with modal by the link. You should create two named views, one for main content (background) and one for modal.
<div ui-view="app"></div>
<div ui-view="modal"></div>
Mark the state, from what you want to access to modal as sticky: true in route definition.
.state('main', {
abstract: true,
url: '/',
templateUrl: '_layout.html'
})
.state('main.index', {
url: '',
sticky: true,
views: {
'app': {
templateUrl: 'index.html'
}
}
})
.state('main.login', {
url: 'login/',
views: {
'modal': {
templateUrl: 'login.html'
}
}
})
Also add an event for stateChangeSuccess:
$rootScope.$on('$stateChangeSuccess', function (ev, to, toParams, from, fromParams) {
if ((from.views && !from.views.modal) || !from.views) {
$rootScope.from = from;
$rootScope.fromParams = fromParams;
}
});
so, when you need to close modal, you can just
$state.go($rootScope.from, $rootScope.fromParams);
There is small problem for that solution. If you reload page on the modal state, then the app ui-view will be empty.
This can be achieved by having a nested state and triggering the modal using onEnter callback:
$stateProvider
.state('contacts', {
url: '/home',
templateUrl: 'home.html',
controller: function($scope, MyService){
$scope.contacts = MyService.getContacts();
}
})
.state('contacts.details', {
url: "^/details/:id", // using the absolute url to not have the "/home" prepended
onEnter: function($state, $uibModal) {
var modal = $uibModal.open({
templateUrl: 'details.html',
controller: function($scope, $stateParams, MyService) {
// get data from service by url parameter
$scope.contact = MyService.getContact($stateParams.id);
}
});
modal.result.finally(function() {
$state.go('^'); // activate the parent state when modal is closed or dismissed
});
}
});
This technique is described in the ui-router's FAQ.
Here the plunk. In this example the modal's scope is created as a child of the $rootScope - the default $uibModal's behavior when no scope is passed to it. In this case we should use the service in the modal's controller to obtain the data by url parameter.
To have master and details URLs look like these - xyz.com/home and xyz.com/detail/123 - we should use the absolute URL (^/details/:id) in the child state.
Using this solution you can open the detail URLs directly and still have both, master and detail states, activated properly, so sharing the detail URL is possible.
I think you can achive that with ngSilent module
https://github.com/garakh/ngSilent
using $ngSilentLocation.silent('/new/path/');
(once you open modal and again after closing it)
Managed to implement this using https://github.com/christopherthielen/ui-router-extras/tree/gh-pages/example/stickymodal
I am trying to implement a tabbed interface akin to this: http://odetocode.com/blogs/scott/archive/2014/04/14/deep-linking-a-tabbed-ui-with-angularjs.aspx
However, on my state change, the controller of the parent state seems to be reinitialized (or a new $scope is created?)
There are two major differences between the example plunkr and my project.
I use a parameter in my url
I resolve different data on the state change for each tab (removing this does nothing).
I am not using ui-bootstrap for the tabs but am triggering a $state.go on ng-click of the tab.
I experimented with the above plunkr and added a dropdown to the parent state; however the parent dropdown values seem to persist when the child states change. I am not too concerned with the child states and will probably end up using sticky states anyways.
I am using wondering if I am doing something fundamentally wrong before I try and add another package to my project.
here is a rough plunkr of what I am trying to do: http://plnkr.co/edit/TmRQN5K8OEc8vHG84G5z?p=preview
here is my config:
app.config(function($stateProvider, $urlRouterProvider){
$urlRouterProvider.when('/main',
function ($state) {
$state.go('parent.tab1', { main_id: '00008' });
});
$stateProvider
//Handle States Here
.state('parent', {
abstract: true,
url: '/parent?main_id',
templateUrl: "main.html",
controller: 'Main_Controller',
resolve: {
//Calls to API
}
})
.state('parent.tab1', {
url: "/applications",
templateUrl: "tab1.html",
controller:'Tab1Ctrl',
resolve: {
//Get some different data from an API
},
})
.state('parent.tab2', {
url: "/phasing",
templateUrl: "tab2.html",
controller: 'Tab2Ctrl',
resolve: {
//More API Data
}
});
});
I've made your plunker working here
$urlRouterProvider
//.when('/main',
.when('',
function ($state) {
$state.go('parent.tab1', { main_id: '00008' })
});
Also there is a change in main.html, which does not use ng-controller any more. We just have to pass the proper Controller name
$stateProvider
//Handle States Here
.state('parent', {
abstract: true,
url: '/parent?main_id',
templateUrl: "main.html",
controller: 'MainController',
resolve: {
//Calls to API
}
})
...
// MainController
// these two names should fit
app.controller("MainController", function($rootScope, $scope, $state) {
So now, it is working, and let's discuss
I use a parameter in my url
I resolve different data on the state change for each tab (removing this does nothing).
I am not using ui-bootstrap for the tabs but am triggering a $state.go on ng-click of the tab.
Quick answers:
parameter in url exists, e.g. #/parent/tab1?main_id=8000
resolve is trigerred for each controller if controller is reinstantiated. That happens when we navigate to that state (among tabs)
no need to use $state.go, I used:
a snippet:
<a ui-sref="parent.tab1({main_id:'00008'})"> go to tab1 with main_id '00008'</a><br />
<a ui-sref="parent.tab2({main_id:'00008'})"> go to tab2 with main_id '00008'</a><br />
<a ui-sref="parent.tab3({main_id:'00008'})"> go to tab3 with main_id '00008'</a><br />

I have an Angular SPA that presents a variety of recommendation lists, and a Google Map of locations, based on different cuts of some restaurant data (see m.amsterdamfoodie.nl). I want each of these lists to have their own URL. In order for Google to crawl the different lists I use <a> tags for the offcanvas navigation.
At present the <a> tag causes a view refresh, which is very noticeable with the map.
I can prevent this using ng-click and $event.preventDefault() (see code snippets below), but then I need to implement a means of updating the browser URL.
But in trying Angular's $state or the browser's history.pushstate, I end up triggering state changes and the view refresh...!
My question is therefore how can I update a model and the URL, but without refreshing the view? (See also Angular/UI-Router - How Can I Update The URL Without Refreshing Everything?)
I have experimented with a lot of approaches and currently have this html
Budget
In the controller:
this.action = ($event) ->
$event.preventDefault()
params = $event.target.href.match(/criteria\/(.*)\/(.*)$/)
# seems to cause a view refresh
# history.pushState({}, "page 2", "criteria/"+params[1]+"/"+params[2]);
# seems to cause a view refresh
# $state.transitionTo 'criteria', {criteria:params[1], q:params[2]}, {inherit:false}
updateModel(...)
And, what is I think is happening is that I am triggering the $stateProvider code:
angular.module 'afmnewApp'
.config ($stateProvider) ->
$stateProvider
.state 'main',
url: '/'
templateUrl: 'app/main/main.html'
controller: 'MainCtrl'
controllerAs: 'main'
.state 'criteria',
url: '/criteria/:criteria/:q'
templateUrl: 'app/main/main.html'
controller: 'MainCtrl'
controllerAs: 'main'
One possible clue is that with the code below if I load e.g. http://afmnew.herokuapp.com/criteria/cuisine/italian then the view refreshes as you navigate, whereas if I load http://afmnew.herokuapp.com/ there are no refreshes, but no URL updates instead. I don't understand why that is happening at all.
This is an example of the way to go if I understand correctly:
$state.go('my.state', {id:data.id}, {notify:false, reload:false});
//And to remove the id from the url:
$state.go('my.state', {id:undefined}, {notify:false, reload:false});
From user l-liava-l in the issue https://github.com/angular-ui/ui-router/issues/64
You can check the $state API here: http://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state
Based on our previous discussions, I want to give you some idea, how to use UI-Router here. I believe, I understand your challenge properly... There is a working example. If this not fully suites, please take it as some inspiration
DISCLAIMER: With a plunker, I was not able to achieve this: http://m.amsterdamfoodie.nl/, but the principle should be in that example similar
So, there is a state definition (we have only two states)
$stateProvider
.state('main', {
url: '/',
views: {
'#' : {
templateUrl: 'tpl.layout.html',
controller: 'MainCtrl',
},
'right#main' : { templateUrl: 'tpl.right.html',},
'map#main' : {
templateUrl: 'tpl.map.html',
controller: 'MapCtrl',
},
'list#main' : {
templateUrl: 'tpl.list.html',
controller: 'ListCtrl',
},
},
})
.state('main.criteria', {
url: '^/criteria/:criteria/:value',
views: {
'map' : {
templateUrl: 'tpl.map.html',
controller: 'MapCtrl',
},
'list' : {
templateUrl: 'tpl.list.html',
controller: 'ListCtrl',
},
},
})
}];
This would be our main tpl.layout.html
<div>
<section class="main">
<section class="map">
<div ui-view="map"></div>
</section>
<section class="list">
<div ui-view="list"></div>
</section>
</section>
<section class="right">
<div ui-view="right"></div>
</section>
</div>
As we can see, the main state does target these nested views of the main state: 'viewName#main', e.g. 'right#main'
Also the subview, main.criteria does inject into layout views.
Its url starts with a sign ^ (url : '^/criteria/:criteria/:value'), which allows to have / slash for main and not doubled slash for child
And also there are controllers, they are here a bit naive, but they should show, that on the background could be real data load (based on criteria).
The most important stuff here is, that the PARENT MainCtrl creates the $scope.Model = {}. This property will be (thanks to inheritance) shared among parent and children. That's why this all will work:
app.controller('MainCtrl', function($scope)
{
$scope.Model = {};
$scope.Model.data = ['Rest1', 'Rest2', 'Rest3', 'Rest4', 'Rest5'];
$scope.Model.randOrd = function (){ return (Math.round(Math.random())-0.5); };
})
.controller('ListCtrl', function($scope, $stateParams)
{
$scope.Model.list = []
$scope.Model.data
.sort( $scope.Model.randOrd )
.forEach(function(i) {$scope.Model.list.push(i + " - " + $stateParams.value || "root")})
$scope.Model.selected = $scope.Model.list[0];
$scope.Model.select = function(index){
$scope.Model.selected = $scope.Model.list[index];
}
})
This should get some idea how we can use the features provided for us by UI-Router:
Absolute Routes (^)
Scope Inheritance by View Hierarchy Only
View Names - Relative vs. Absolute Names
Check the above extract here, in the working example
Extend: new plunker here
If we do not want to have map view to be recreated, we can just omit that form the child state def:
.state('main.criteria', {
url: '^/criteria/:criteria/:value',
views: {
// 'map' : {
// templateUrl: 'tpl.map.html',
// controller: 'MapCtrl',
//},
'list' : {
templateUrl: 'tpl.list.html',
controller: 'ListCtrl',
},
},
})
Now our map VIEW will be just recieving changes in the model (could be watched) but view and controller won't be rerendered
ALSO, there is another plunker http://plnkr.co/edit/y0GzHv?p=preview which uses the controllerAs
.state('main', {
url: '/',
views: {
'#' : {
templateUrl: 'tpl.layout.html',
controller: 'MainCtrl',
controllerAs: 'main', // here
},
...
},
})
.state('main.criteria', {
url: '^/criteria/:criteria/:value',
views: {
'list' : {
templateUrl: 'tpl.list.html',
controller: 'ListCtrl',
controllerAs: 'list', // here
},
},
})
and that could be used like this:
<h4>{{main.hello()}}</h4>
<h4>{{list.hello()}}</h4>
The last plunker is here
you can use scope inheritance to update url without refreshing view
$stateProvider
.state('itemList', {
url: '/itemlist',
templateUrl: 'Scripts/app/item/ItemListTemplate.html',
controller: 'ItemListController as itemList'
//abstract: true //abstract maybe?
}).state('itemList.itemDetail', {
url: '/:itemName/:itemID',
templateUrl: 'Scripts/app/item/ItemDetailTemplate.html',
controller: 'ItemDetailController as itemDetail',
resolve: {
'CurrentItemID': ['$stateParams',function ($stateParams) {
return $stateParams['itemID'];
}]
}
})
if child view is inside parent view both controllers share same scope.
so you can place a dummy (or neccessary) ui-view inside parent view which will be populated by child view.
and insert a
$scope.loadChildData = function(itemID){..blabla..};
function in parent controller which will be called by child controller on controller load. so when a user clicks
<a ui-sref="childState({itemID: 12})">bla</a>
only child controller and child view will be refreshed. then you can call parent scope function with necessary parameters.
The short answer ended up being do not put the map inside a view that changes. The accepted answer provides a lot more detail on how to structure a page with sub-views, but the key point is not to make the map part of the view but to connect its behaviour to a view that does change and to use a Controller to update the market icons.
I'm working on an angular app that has ui-router module.
When entering a certain state of the router, I show a modal dialog, which then replaces my parent view. I would like to keep the parent view and show the modal as overlay. Is there a way to do it with ui-router?
To give an example:
$stateProvider.state("clients.list", {
url: "/list",
templateUrl: "app/client/templates/client-list.tpl.html",
controller: moduleNamespace.clientListController,
resolve: {
clients: function (ClientService) {
return ClientService.all();
}
}
})
// This will replace "clients.list", and show the modal
// I want to just overlay the modal on top of "clients.list"
.state("clients.add", {
url: "/add",
onEnter: function ($stateParams, $rootScope, $state, ngDialog) {
ngDialog.open({
controller: moduleNamespace.clientAddController,
template: "app/client/templates/client-add.tpl.html"
});
$rootScope.$on("ngDialog.closed", function (e, $dialog)
if ($state.current.name !== "clients.list") $state.transitionTo("clients.list");
});
}
})
Thanks
I think the proper solution would be something like:
$stateProvider.state("clients.list", {
url: "/list",
templateUrl: "app/client/templates/client-list.tpl.html",
controller: moduleNamespace.clientListController,
resolve: {
clients: function (ClientService) {
return ClientService.all();
}
}
})
.state("clients.list.add", {
url: "^/add",
})
Important things are I made /add absolute by adding a ^. Most people would have just done /list/add because the default behavior of nested state is to add them together...the ^ bypasses this. You also would need to on state load style this thing so its a "modal" and is on top of other content.
And then inside of clients.list state you would need to update /client-list.tpl.html to have an ng-view that would style itself on top of the parent view.
I can create a plunkr if need be, but if I do that I am basically implementing everything for you.
