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

I'm learning Angular and I'm having problem on the routing. I've tried to solve it myself but have no idea what it can be.
Here's my script and a Plunker link of my script
var singleApp = angular.module('singleApp', ['ngRoute'])
.config([$routeProvider, $locationProvider, function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {
templateUrl: 'pages/home.html',
controller: 'mainController'
})
.when('/about', {
templateUrl: 'pages/about.html',
controller: 'aboutController'
})
.when('/contact', {
templateUrl: 'pages/contact.html',
controller: 'contactController'
});
// Deletes # in URL with HTML History API
$locationProvider.html5Mode(true);
}])
.controller('mainController', function($scope) {
$scope.message = 'This is the main page';
})
.controller('aboutController', function($scope) {
$scope.message = 'This is the about page';
})
.controller('contactController', function($scope) {
$scope.message = 'This is the message page';
});
I've imported the both angular and routing scripts in html.
The pages has just $message
The first issue is with your config. You're using a great practice by using an array for your injections but the first arguments must be strings. Change this:
.config([$routeProvider, $locationProvider, function($routeProvider, $locationProvider) {
to this
.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
Then... remove this line:
$locationProvider.html5Mode(true);
Here's information about HTML5 mode:
https://docs.angularjs.org/error/$location/nobase
Enabling HTML 5 Mode in AngularJS 1.2
http://plnkr.co/edit/EXMiz3bAEttTQac0uvgh?p=preview
You have syntax error, config function should be like this
.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
http://plnkr.co/edit/4csvt10yfolOepqECh51?p=preview
Removes the following line
//Deletes # in URL with HTML History API
$locationProvider.html5Mode(true);
Many of the errors and especially reference can view them in the browser console
You must modify the parameters of your config, should go well
.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
Compare and see your code
var singleApp = angular.module('singleApp', ['ngRoute'])
singleApp.config(function($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'pages/home.html',
controller: 'mainController'
})
.when('/about', {
templateUrl: 'pages/about.html',
controller: 'aboutController'
})
.when('/contact', {
templateUrl: 'pages/contact.html',
controller: 'contactController'
});
});
singleApp.controller('mainController', function($scope) {
$scope.message = 'This is the main page';
});
singleApp.controller('aboutController', function($scope) {
$scope.message = 'This is the about page';
});
singleApp.controller('contactController', function($scope) {
$scope.message = 'This is the message page';
});
I'm using routeProvider to set the controller and a route param when my application is configured. Here's the code that I'm using:
app.config(['$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) {
$routeProvider.
when('/person/:uuid/report', {
templateUrl: 'partials/CandidateCtrl.html', //TODO : replace with the good template
controller: 'CandidateCtrl'
}).
when('/person/:uuid/confirm', {
templateUrl: 'partials/ConfirmCtrl.html', //TODO : replace with the good template
controller: 'ConfirmCtrl'
}).
when('/person/add', {
templateUrl: 'partials/AddCtrl.html', //TODO : replace with the good template
controller: 'AddCtrl'
}).
otherwise({
redirectTo: 'Something' //TODO : replace with the good url
});
}]);
I was serving the views by via my web-mvc. I've since changed it to serve a layout and have the partial pages be kept in the resource folder.
I'm trying to get a query value from my url using angular's routeParams.
I've included angular-route in my html page:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.4/angular-route.min.js"></script>
Included Ng-Route in my app:
var app = angular.module('app', [
'ngRoute',
'reportController'
]);
And set up my controller as following:
var reportController = angular.module('reportController', []);
reportController.controller('CandidateCtrl', ['$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.
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¶m2=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 = $routeParams.param2;
}]);
calling from Home.html
<div class="container">
<h2> Welcome </h2>
Students
</div>
I'm trying to learn how routes work in AngularJS to make a little application that allows users to login and write comments in a live feed. However the whole concept of routes is a bit blurry for me atm and i can't get this right.
My standard index.html containing an ng-view and necessary scripts.
<!DOCTYPE html>
<html ng-app="myApp">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.3/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-rc.3/angular-route.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.js"></script>
<script src="//cdn.firebase.com/js/client/1.0.21/firebase.js"></script>
<script src="//cdn.firebase.com/libs/angularfire/0.8.2/angularfire.js"></script>
<script src="//cdn.firebase.com/js/simple-login/1.6.3/firebase-simple-login.js"></script>
<script src="controller.js"></script>
<title>Test Login App</title>
</head>
<body>
<div class="container">
<div ng-view></div>
</div>
</body>
</html>
My controller containing module and routeprovider.
var myApp = angular.module('myApp', [
'ngAnimate',
'ngCookies',
'ngResource',
'ngRoute',
'ngSanitize',
'ngTouch',
'firebase',
'firebase.utils',
'simpleLogin'
]);
myApp.config(function($routeProvider) {
$routeProvider.
when('/', { controller: handleCtrl, templateUrl: 'handler.html' }).
when('/chatt', { controller: MyController, templateUrl: 'chat.html' }).
when('/login', { controller: loginCtrl, templateUrl: 'login.html' }).
otherwise({ redirectTo: '/handler' });
});
myApp.config(['$locationProvider', function($locationProvider) {
$locationProvider.html5Mode(true);
}])
myApp.controller('MyController', ['$scope', '$firebase',
function($scope, $firebase) {
//CREATE A FIREBASE REFERENCE
var ref = new Firebase("https://ivproj.firebaseio.com/");
// GET MESSAGES AS AN ARRAY
$scope.messages = $firebase(ref).$asArray();
//ADD MESSAGE METHOD
$scope.addMessage = function(e) {
//LISTEN FOR RETURN KEY
if (e.keyCode === 13 && $scope.msg) {
//ALLOW CUSTOM OR ANONYMOUS USER NAMES
var name = $scope.name || 'anonymous';
//ADD TO FIREBASE
$scope.messages.$add({
from: name,
body: $scope.msg
});
//RESET MESSAGE
$scope.msg = "";
}
}
}
]);
The $routeprovider function should direct me to handler that is a simple .html file containing two buttons that in turn redirects to other htmls.
I think you have the syntax of the otherwise call in your config section wrong. Change what you have for this instead:
otherwise('/handler');
hope this helps...
you are missing '' in controller part. correct code should look like -
myApp.config(function($routeProvider) {
$routeProvider.
when('/', { controller: 'handleCtrl', templateUrl: 'handler.html' }).
when('/chatt', { controller: 'MyController', templateUrl: 'chat.html' }).
when('/login', { controller: 'loginCtrl', templateUrl: 'login.html' }).
otherwise({ redirectTo: '/handler' });
});
Make sure that you are referring the correct path in templateUrl.
and look at my earlier post to get a better idea - How to navigate in Angular App
myApp.config(function($routeProvider) {
$routeProvider.
when('/', { controller: 'handleCtrl', templateUrl: 'handler.html' }).
when('/chat', { controller: 'MyController', templateUrl: 'chat.html' }).
when('/login', { controller: 'loginCtrl', templateUrl: 'login.html' }).
otherwise({ redirectTo: '/handler' });
});
The $routeProvider.when() method in the above code actually creates a route with the given configuration. And the three .when()'s are creating three different routes.
But in your $routeProvider.otherwise('/handler'), you are telling angular to go to a route called /handler if the user tries to navigate anywhere outside the configured routes.
The mistake you are doing here is, you did not define a route at /handler. So you need to first define that route and then use it in .otherwise().
Try changing your configuration to reflect the below.
myApp.config(function($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider.
when('/handler', { controller: 'handleCtrl', templateUrl: 'handler.html' }).
when('/chat', { controller: 'MyController', templateUrl: 'chat.html' }).
when('/login', { controller: 'loginCtrl', templateUrl: 'login.html' }).
otherwise({ redirectTo: '/handler' });
});
