Angular: Passing params from $routeProvider to controller - javascript

I have multiple routes that invoke the same Controller and I would like to pass different variables to it.
// Example
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController' // should get passed 'exampleA'
}).
when('/b', {
templateUrl: 'test.html',
controller: 'MyController' // should get passed 'exampleB'
});
I know that I could use the "resolve" object:
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController',
resolve: {test: function() { return true; }}
});
To pass a value as a dependency:
app.controller('MyController', ['$scope', 'test', function ($scope, test) {
console.log(test); // true
}
My problem with that approach is that my app crashes if the resolve object is missing on other routes and I would like to pass optional params.
Is there any way to pass specific params to the Controller (from the route provider)?
Thank you

Routing:
$routeProvider.
when('/a', {
templateUrl: 'test.html',
controller: 'MyController',
paramExample: 'exampleA'
}).
when('/b', {
templateUrl: 'test.html',
controller: 'MyController',
paramExample: 'exampleB'
});
Access: inject $route in your controller then use this
app.controller('MyController', ['$scope', '$route', function ($scope, $route) {
var paramValue = $route.current.$$route.paramExample;
console.log(paramValue);
}

You can use resolve and $route.currrent.params.test to pass the parameter like this:
$routeProvider
.when('/a', {
templateUrl: 'view.html',
controller: 'MainCtrl',
resolve: {
test: function ($route) { $route.current.params.test = true; }
}
})
.when('/b', {
templateUrl: 'view.html',
controller: 'MainCtrl',
resolve: {
test: function ($route) { $route.current.params.test = false; }
}
})
Then in your controller you can access it from the $routeParams:
app.controller('MainCtrl', function($scope, $routeParams) {
$scope.test = $routeParams.test;
})

The most natural way to do this is doing what you would normally do when you want to load a page with parameters: use query parameters: http://yoururl.com?param1=value&param2=value
ngRoute comes with the service $routeParams which you can inject in your controller. Now you can simply retrieve the values like this $routeParams.param1.
Another way to do this is to retrieve the path with $location.path and set the variable there.

using $routeParams
in Main js file
routeApp.config(function($routeProvider) {
$routeProvider
.when('/home', {
templateUrl: '../sites/./home.html',
controller: 'StudentController'
})
.when('/viewStudents/:param1/:param2', {
templateUrl: '../sites/./viewStudents.html',
controller: 'StudentController'
})
.otherwise({
redirectTo: '/'
});
});
routeApp.controller('StudentController',['$filter','$routeParams', '$location',function($filter,$routeParams,$location){
var StudentCtrl = this;
StudentCtrl.param1 = $routeParams.param1;
StudentCtrl.param2 = $routeParams.param2;
}]);
calling from Home.html
<div class="container">
<h2> Welcome </h2>
Students
</div>

How do I pass parameters to the controller in $routeProvider?

I am new to Angular.js ....Based on the id, the fullPostController gets the required data using $http, but how am I supposed to pass the postId to the controller?
'use strict';
var myAPP = angular.module('myAPP', [ 'ngRoute' ]);
myAPP.config(['$routeProvider',
function (
$routeProvider
) {
$routeProvider.
when('/', {
templateUrl: 'pages/home.html',
controller: 'mainController'
}).
when('/post/:postId', {
templateUrl: 'pages/full_post.html',
controller: 'fullPostController'
}).
otherwise({
redirectTo: '/'
});
}]);
How do I pass the postId to fullPostController??
inject $routeParams in the controller, the post id is $routeParams.postId

Angular Set Controller and routeParams

I'm using routeProvider to set the controller and a route param when my application is configured. Here's the code that I'm using:
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/person/:uuid/report', { controller: 'CandidateCtrl' }).
when('/person/:uuid/confirm', { controller: 'ConfirmCtrl', }).
when('/person/add', { controller: 'AddCtrl' })
}]);
However, the controller is not being set correctly. Additionally, when I set the controller with ng-controller in the page itself, the routeParams object is empty. What am I doing wrong?
Edit:
I've also tried this, which also isn't associating the controller with the page nor setting the route-params.
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/person/:uuid/report', { controller: 'CandidateCtrl', template: 'templates/report.html' }).
when('/person/:uuid/confirm', { controller: 'ConfirmCtrl', template: 'templates/confirm.html' }).
when('/person/add', { controller: 'AddCtrl', template: 'templates/add.html' })
}]);
Here's the controller that I'm testing this out with:
appController.controller('CandidateCtrl', ['$routeParams',
function($routeParams) {
console.log($routeParams);
}]);
Try to add templateUrl
app.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/person/:uuid/report', {
templateUrl: 'partials/CandidateCtrl.html', //TODO : replace with the good template
controller: 'CandidateCtrl'
}).
when('/person/:uuid/confirm', {
templateUrl: 'partials/ConfirmCtrl.html', //TODO : replace with the good template
controller: 'ConfirmCtrl'
}).
when('/person/add', {
templateUrl: 'partials/AddCtrl.html', //TODO : replace with the good template
controller: 'AddCtrl'
}).
otherwise({
redirectTo: 'Something' //TODO : replace with the good url
});
}]);
I was serving the views by via my web-mvc. I've since changed it to serve a layout and have the partial pages be kept in the resource folder.

Angular $routeParams empty object

I'm trying to get a query value from my url using angular's routeParams.
I've included angular-route in my html page:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4/angular-route.min.js"></script>
Included Ng-Route in my app:
var app = angular.module('app', [
'ngRoute',
'reportController'
]);
And set up my controller as following:
var reportController = angular.module('reportController', []);
reportController.controller('CandidateCtrl', ['$scope', '$routeParams',
function($scope, $routeParams) {
console.log(JSON.stringify($routeParams, null, 4));
$scope.person = $routeParams.person;
}]);
When I access the following URL, however, routeParams is an empty object: {}.
http://localhost:8080/report?person=afe75cc7-fa61-41b3-871d-119691cbe5ad
What am I doing wrong?
Edit:
I've configure the possible route - my routeParams object is still coming up null. I've tried:
famaApp.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/report:person', {templateUrl: 'Report.html', controller: 'CandidateCtrl'});
}]);
and
when('/report?person', {templateUrl: 'Report.html', controller: 'CandidateCtrl'});
Rather then accessing like
http://localhost:8080/report?person=afe75cc7-fa61-41b3-871d-119691cbe5ad
try to access it like
http://localhost:8080/#/report/afe75cc7-fa61-41b3-871d-119691cbe5ad
you will get the guid in $route.Params
You have to set your routes to receive the arguments you want with $routeProvider..
Example:
app.config(['$routeProvider', '$locationProvider' function ($routeProvider, $locationProvider) {
$routeProvider
.when('/',
{
templateUrl: 'someHtmlUrl',
controller: 'someController',
controllerAs: 'someCtrl',
caseInsensitiveMatch: true
})
.when('/:person',
{
templateUrl: 'someHtmlUrl',
controller: 'someController',
controllerAs: 'someCtrl',
caseInsensitiveMatch: true
})
.otherwise(
{
templateUrl: 'someHtmlUrl'
});
$locationProvider.html5Mode(true); //Use html5Mode so your angular routes don't have #/route
}]);
Then you can just do
http://localhost:8080/afe75cc7-fa61-41b3-871d-119691cbe5a
And the $routeProvider will call your html and your controller as you can see with the .when('/:person'.. and then you can try and access your $routeParams and you will have your person there, $routeParams.person.

$routeParams Empty on $locationChangeSuccess

I configure my app in the following run block. Basically I want to preform an action that requires me to know the $routeParams every $locationChangeSuccess.
However $routeParams is empty at this point! Are there any work rounds? What's going on?
app.run(['$routeParams', function ($routeParams) {
$rootScope.$on("$locationChangeSuccess", function () {
console.log($routeParams);
});
}]);
UPDATE
function configureApp(app, user) {
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider.
when('/rentroll', {
templateUrl: 'rent-roll/rent-roll.html',
controller: 'pwRentRollCtrl'
}).
when('/bill', {
templateUrl: 'bill/bill/bill.html',
controller: 'pwBillCtrl'
}).
when('/fileroom', {
templateUrl: 'file-room/file-room/file-room.html',
controller: 'pwFileRoomCtrl'
}).
when('/estate-creator', {
templateUrl: 'estate/creator.html'
}).
when('/estate-manager', {
templateUrl: 'estate/manager.html',
controller: 'pwEstateManagerCtrl'
}).
when('/welcomepage', {
templateURL: 'welcome-page/welcome-page.html',
controller: 'welcomePageCtrl'
}).
otherwise({
redirectTo: '/welcomepage'
});
}]);
app.run(['$rootScope', '$routeParams', 'pwCurrentEstate','pwToolbar', function ($rootScope, $routeParams, pwCurrentEstate, pwToolbar) {
$rootScope.user = user;
$rootScope.$on("$locationChangeSuccess", function () {
pwToolbar.reset();
console.log($routeParams);
});
}]);
}
Accessing URL:
http://localhost:8080/landlord/#/rentroll?landlord-account-id=ahlwcm9wZXJ0eS1tYW5hZ2VtZW50LXN1aXRlchwLEg9MYW5kbG9yZEFjY291bnQYgICAgICAgAoM&billing-month=2014-06
this worked for me, inside your run callback:
.run(function($rootScope, $routeParams, $location) {
$rootScope.$on("$locationChangeSuccess", function() {
var params = $location.search();
console.log(params);
console.log('landlord-account-id:', params['landlord-account-id']);
console.log('billing-month', params['billing-month']);
});
})
By accessing /rentroll you will get empty $routeParams because your $routeProvider
configuration for that path is not expecting any variable on URL.
$routeParams is used for getting variable value of your URL. For example :
$routeProvider
.when('/rentroll/:variable', {...});
and access it on /rentroll/something will give you $routeParams as below :
$routeParams.variable == 'something';
https://docs.angularjs.org/api/ngRoute/service/$routeParams
Explains a bit about when the $routeParams are available and why.
To solution here might be to use $route.current.params

Routes fetched from controller

is it possible to load url from controllers in routeProvider?
.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/LALA', {
controller: 'LalaController',
templateUrl: '/mlala.html'
})
.when('/HOHO', {
controller: 'HohoController',
templateUrl: '/hoho.html'
})
.otherwise({redirectTo: '/'});
and I would like something like this:
.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/MO', {
controller: 'MOController',
templateUrl: $scope.url
})
.when('/MOCache', {
controller: 'MOCacheController',
templateUrl: $scope.url
})
.otherwise({redirectTo: '/'});
Route URLs would be defined in Controllers.
Well, no.
But you can use named groups, assign a function to templateUrl and get the route parameters passed in:
.when('/MO/:page', { // <-- ':page' is a named group in the pattern
controller: 'MOController',
templateUrl: function (params) {
// use the route parameters to return a custom route
return 'views/partials/mo/' + params.page + '.html';
}
})
Than you can just inject whatever custom parameter you like in your views, e.g.:
<!-- 'paws' and 'whiskers' will be passed to the route params -->
paws page!
whiskers page!
Look, mommy, no controllers!

$routeProvider on the AngularJS docs.
