Angular state with parametes - angularjs

I am trying to navigate to my state with providing some parameters to it.
Here is my code:
State:
a = angular.module('app.panel', []);
a.config(
function ($stateProvider) {
$stateProvider
.state('body.new', {
url: 'new',
templateUrl:function($stateParams){
return 'http://localhost/' + 'new.aspx?panel_id=' + $stateParams.panel_id
},
controller: 'newController'
});
});
I am navigating to this state like this:
var url = $state.href('body.new', { parameter: $scope.parameters });
$window.open(url, '_blank');
In the state $stateParams is undefined. If I am doing it in a wrong way what the correct way might be?
Thanks for help.
Update 1.
I have modified my code to this:
url: 'new/:panel_id',
params: {
parameter: null,
},
But my problem is that I am still getting $stateParams undefined.

Just cutting the code down a little bit, it needs altering to this:
a.config(
function ($stateProvider, $stateParams) {
$stateProvider ...
It's complaining about $stateParams because you weren't stating it as a dependency.
EDIT:
Or, try this:
a.config(
function ($stateProvider, $state) {
$stateProvider ...
Then you could access it via $state.params.id

angular $stateprovider not working as expected

I'm using angular $stateProvider to allow routes throughout my app. I have an index.html and I am changing the html content inside using the following...
app.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/app');
$stateProvider
.state('app', {
url: '/app',
templateUrl: 'templates/menu.html',
controller: 'AppCtrl'
})
.state('app.accounts', {
url: '/accounts',
templateUrl: 'templates/accounts.html'
})
});
The first route works, when you open the app template/menu.html is put inside index.html. The problem occur when I try to change the state.
At the moment, I am implementing an API in my app, what the API does is irrelevant, but on success I want the API to change the state to app.accounts, see below...
app.controller('AppCtrl', function($scope, $ionicModal, $timeout) {
$scope.create = function() {
var linkHandler = Plaid.create({
env: 'tartan',
clientName: 'Example Project',
key: 'test_key',
product: 'connect',
//On success I want to change the state
onSuccess: function(token) {
window.location = '/app/accounts';
},
});
linkHandler.open();
}
});
Above, on success, I attempt changing the state, but when window.location is called, I get the error...
net::ERR_FILE_NOT_FOUND (file:///app/accounts)
I am not sure why I get this error because the first route works fine. Any idea how I can fix this?
Your path is wrong. That's what the error is saying. It can't find that route.
Try $window.location.href = "/#/app/accounts";
Remember to inject $window in the controller.
However a better way would be to inject the $state service and use it to navigate:
$state.go('app.accounts')

Angular state : pass multiple parameter without changing url querystring to controller

I want to send a parameter from app.run to my loginController. Because, I call a state.go() from the $rootScope.$on() defined inside the app.run.
app.run('$rootScope', '$state', '$stateParams',function($rootScope, $state, $stateParams(){
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
$rootScope.$on('unauthorized_access', function (event, args) {
$state.go("page.login", {'error': args.error,'msg': args.msg});
});
}]);
I have
app.config(['$stateProvider','$urlRouterProvider',function($stateProvider, $urlRouterProvider, $httpProvider){
$urlRouterProvider.otherwise('/');
$stateProvider
// some parts omitted...
.state('page.login', {
url: '/login',
views: {
'page': {
templateUrl: 'app/landingPage/login.html',
controller: 'loginController',
params: {obj : {error : null, message: null} }
}
}
});
}]);
and I want to pass parameters to the loginController from app.run, through $state.go() during transition.
$state.go("page.login", {'error': err,'message': msg});
and in my controller, this is how I am trying to receive the params...
app.controller('loginController',['$scope', '$state', '$stateParams', function($scope, $state, $stateParams){
console.log($stateParams.obj);
}]);
I do not want to change the url to >> url: '/login/:params' etc. in stateProvider
I referenced this page : stackoverflow example
but,was not helpful. Any help is appreciated. Apologies for my poor communication.
After a long research, I ended up with weird solution. I still doubt, whether this is even a solution. However, it does work for me.... I made a hack of ui.router LOL ....
I am using Angular ui-router version v0.2.18. and there at line no. 3160, they have put a line of code like :
// Store the hash param for later (since it will be stripped out by various methods)
var hash = toParams['#'];
and in line no. 3223 they have
if (shouldSkipReload(to, toParams, from, fromParams, locals, options)) {
if (hash) toParams['#'] = hash;
So, I thought of passing my object with a '#' key like this
.state('page.login', {
url: '/login',
views: {
'body#page': {
templateUrl: 'app/landingPage/login.html',
controller: 'loginController',
params: {'#' : null},
}
},
authenticate: false
});
and like this
$rootScope.$on('unauthorized_access', function (event, args) {
$state.go("page.login", {'#' : {'error': args.error,'msg': args.msg}});
});
and surprise, it worked.....
I got the object logged in console : console.log($stateParams['#']);
I know the solution is cunning[udayip as in malayalam]... but then it worked for me... I will not mark this as an answer. So, I request some angular experts to provide a real solution. If some experts say, this can be a solution, I will mark this as the answer.

Angular module config - provide parameter for templateURL

I am trying to use a parameter in my templateURL. here is relative code:
a = angular.module('newmodule', []);
a.config(['$stateProvider',
function ($stateProvider, $rootScope) {
$stateProvider
.state('body.new', {
url: 'new?panelid',
params: {
'panelid': function ($rootScope) {
return $rootScope.panelid;
}
},
templateUrl: function($stateParams){
return getBaseUrl() + 'newpage.aspx?panel_id='+ $stateParams.panelid;
},
controller: 'newController'
});
}]);
The navigation to this state is done like this:
var url = $state.href('body.new');
$window.open(url, '_blank');
from another state's controller.
I am checking what's been sent to the server and see that $stateParams.panelid is undefined. But, the interesting thing is if instead of returning $rootScope.panelid I return a value like '44' then it works fine. Can someone please explain what's exactly is wrong here.
Thanks

Accessing ui-router state controller's data in data section

I have the state configuration defined in as follows:
angular.module('app', ['ui.router')
.config(function ($stateProvider, $urlRouterProvider) {
.state('element', {
url: '/element',
templateUrl: 'element.html',
controller: 'ElementCtrl',
controllerAs:'ec',
data: {
title: 'Element {{ec.name}}',
}
})
.state('element.detail', {
url: '/detail',
templateUrl: 'detail.html',
controller: 'HomeCtrl',
controllerAs:'hc',
data: {
title: 'Detail {{hc.age}}',
}
})
.controller('ElementCtrl', function ($scope, $stateParams) {
this.name = "myName";
})
.controller('HomeCtrl', function ($scope, $stateParams) {
this.age = "myName22";
});
Here, I want to dynamically determine the data.title field based on the value assigned to the variable in the controller.
Is there a way to do this?(It is better if I do this before the state is activated).
It is not possible. See more here:
Accessing parameters in custom data
there is NO way how to set these data dynamically. E.g. based on the $stateParams. These settings are expected to be defined in the .config() phase, not evaluated in .run()(in compariosn with others like resolve, templateUrl...)
The data : {} is intended as a static setting, defined in a config phase.
The way to go is to use resolve : {}:
Resolve
You can use resolve to provide your controller with content or data that is custom to the state. resolve is an optional map of dependencies which should be injected into the controller.

How to send and retrieve parameters using $state.go toParams and $stateParams?

I am using AngularJS v1.2.0-rc.2 with ui-router v0.2.0. I want to pass the referrer state to another state so I use the toParams of $state.go like so:
$state.go('toState', {referer: $state.current.name});
According to the docs, this should populate the $stateParams on the toState controller, but it is undefined. What am I missing?
I've created a plunk to demonstrate:
http://plnkr.co/edit/ywEcG1
If you want to pass non-URL state, then you must not use url when setting up your state. I found the answer on a PR and did some monkeying around to better understand.
$stateProvider.state('toState', {
templateUrl:'wokka.html',
controller:'stateController',
params: {
'referer': 'some default',
'param2': 'some default',
'etc': 'some default'
}
});
Then you can navigate to it like so:
$state.go('toState', { 'referer':'jimbob', 'param2':37, 'etc':'bluebell' });
Or:
var result = { referer:'jimbob', param2:37, etc:'bluebell' };
$state.go('toState', result);
And in HTML thusly:
<a ui-sref="toState(thingy)" class="list-group-item" ng-repeat="thingy in thingies">{{ thingy.referer }}</a>
This use case is completely uncovered in the documentation, but I think it's a powerful means on transitioning state without using URLs.
The Nathan Matthews's solution did not work for me but it is totally correct but there is little point to reaching a workaround:
The key point is: Type of defined parameters and toParamas of $state.go should be same array or object on both sides of state transition.
For example when you define a params in a state as follows you means params is array because of using "[]":
$stateProvider
.state('home', {
templateUrl: 'home',
controller: 'homeController'
})
.state('view', {
templateUrl: 'overview',
params: ['index', 'anotherKey'],
controller: 'overviewController'
})
So also you should pass toParams as array like this:
params = { 'index': 123, 'anotherKey': 'This is a test' }
paramsArr = (val for key, val of params)
$state.go('view', paramsArr)
And you can access them via $stateParams as array like this:
app.controller('overviewController', function($scope, $stateParams) {
var index = $stateParams[0];
var anotherKey = $stateParams[1];
});
Better solution is using object instead of array in both sides:
$stateProvider
.state('home', {
templateUrl: 'home',
controller: 'homeController'
})
.state('view', {
templateUrl: 'overview',
params: {'index': null, 'anotherKey': null},
controller: 'overviewController'
})
I replaced [] with {} in params definition. For passing toParams to $state.go also you should using object instead of array:
$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' })
then you can access them via $stateParams easily:
app.controller('overviewController', function($scope, $stateParams) {
var index = $stateParams.index;
var anotherKey = $stateParams.anotherKey;
});
All I had to do was add a parameter to the url state definition like so
url: '/toState?referer'
Doh!
Not sure if it will work with AngularJS v1.2.0-rc.2 with ui-router v0.2.0.
I have tested this solution on AngularJS v1.3.14 with ui-router v0.2.13.
I just realize that is not necessary to pass the parameter in the URL as gwhn recommends.
Just add your parameters with a default value on your state definition.
Your state can still have an Url value.
$stateProvider.state('state1', {
url : '/url',
templateUrl : "new.html",
controller : 'TestController',
params: {new_param: null}
});
and add the param to $state.go()
$state.go('state1',{new_param: "Going places!"});
None of these examples on this page worked for me. This is what I used and it worked well. Some solutions said you cannot combine url with $state.go() but this is not true. The awkward thing is you must define the params for the url and also list the params. Both must be present. Tested on Angular 1.4.8 and UI Router 0.2.15.
In the state add your params to end of state and define the params:
url: 'view?index&anotherKey',
params: {'index': null, 'anotherKey': null}
In your controller your go statement will look like this:
$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' });
Then to pull the params out and use them in your new state's controller (don't forget to pass in $stateParams to your controller function):
var index = $stateParams.index;
var anotherKey = $stateParams.anotherKey;
console.log(anotherKey); //it works!
In my case I tried with all the options given here, but no one was working properly (angular 1.3.13, ionic 1.0.0, angular-ui-router 0.2.13). The solution was:
.state('tab.friends', {
url: '/friends/:param1/:param2',
views: {
'tab-friends': {
templateUrl: 'templates/tab-friends.html',
controller: 'FriendsCtrl'
}
}
})
and in the state.go:
$state.go('tab.friends', {param1 : val1, param2 : val2});

I've spent a good deal of time fighting with Ionic / Angular's $state & $stateParams;
To utilize $state.go() and $stateParams you must have certain things setup and other parameters must not be present.
In my app.config() I've included $stateProvider and defined within it several states:
$stateProvider
.state('home', {
templateUrl: 'home',
controller: 'homeController'
})
.state('view', {
templateUrl: 'overview',
params: ['index', 'anotherKey'],
controller: 'overviewController'
})
The params key is especially important. As well, notice there are NO url keys present... utilizing stateParams and URLs do NOT mix. They are mutually exclusive to each other.
In the $state.go() call, define it as such:
$state.go('view', { 'index': 123, 'anotherKey': 'This is a test' })
The index and anotherKey $stateParams variables will ONLY be populated if they are first listed in the $stateController params defining key.
Within the controller, include $stateParams as illustrated:
app.controller('overviewController', function($scope, $stateParams) {
var index = $stateParams.index;
var anotherKey = $stateParams.anotherKey;
});
The passed variables should be available!
Try With reload: true?
Couldn't figure out what was going on for the longest time -- turns out I was fooling myself. If you're certain that things are written correctly and you will to use the same state, try reload: true:
.state('status.item', {
url: '/:id',
views: {...}
}
$state.go('status.item', { id: $scope.id }, { reload: true });
Hope this saves you time!
I'd faced a similar problem. I ended up with a working solution after a lot of googling and trial and test. Here is my solution which would work for you.
I have two controllers - searchBoxController and stateResultController and a parameter named searchQuery to be passed from a view having a search box to a view showing the results fetched from a remote server. This is how you do it:
Below is the controller from which you call the next view using $state.go()
.controller('searchBoxController', function ($scope, $state) {
$scope.doSearch = function(){
var searchInputRaw = $scope.searchQueryInput;
$state.go('app.searchResults', { searchQuery: searchInput });
}
})
Below is the state that would be called when the $state.go() gets executed:
.state('app.searchResults',
{
url: '/searchResults',
views:
{
'menuContent': { templateUrl: 'templates/searchResult.html', controller: 'stateResultController' }
},
params:
{
'searchQuery': ''
}
})
And finally, the controller associated with the app.searchResults state:
.controller('stateResultController', function ($scope, $state, $stateParams, $http) {
$scope.searchQueryInput = $stateParams.searchQuery;
});
And in my case of a parent/child state. all the parameters declared in child state has to be known by the parent state
.state('full', {
url: '/full',
templateUrl: 'js/content/templates/FullReadView.html',
params: { opmlFeed:null, source:null },
controller: 'FullReadCtrl'
})
.state('full.readFeed', {
url: '/readFeed',
views: {
'full': {
templateUrl: 'js/content/templates/ReadFeedView.html',
params: { opmlFeed:null, source:null },
controller: 'ReadFeedCtrl'
}
}
})
The solution we came to having a state that took 2 parameters was changing:
.state('somestate', {
url: '/somestate',
views: {...}
}
to
.state('somestate', {
url: '/somestate?id=:&sub=:',
views: {...}
}
Your define following in router.js
$stateProvider.state('users', {
url: '/users',
controller: 'UsersCtrl',
params: {
obj: null
}
})
Your controller need add $stateParams.
function UserCtrl($stateParams) {
console.log($stateParams);
}
You can send an object by parameter as follows.
$state.go('users', {obj:yourObj});
I was trying to Navigate from Page 1 to 2, and I had to pass some data as well.
In my router.js, I added params name and age :
.state('page2', {
url: '/vehicle/:source',
params: {name: null, age: null},
.................
In Page1, onClick of next button :
$state.go("page2", {name: 'Ron', age: '20'});
In Page2, I could access those params :
$stateParams.name
$stateParams.age
If this is a query parameter that you want to pass like this:
/toState?referer=current_user
then you need to describe your state like this:
$stateProvider.state('toState', {
url:'toState?referer',
views:{'...'}
});
