Angular 1 - get current URL parameters

Question

I want to extract data from current URL and use it in controller. For example I have this url:

app.dev/backend/surveys/2

Bits t

Answer 1

Better would have been generate url like

app.dev/backend?type=surveys&id=2

and then use

var type=$location.search().type;
var id=$location.search().id;

and inject $location in controller.

Answer 2

To get parameters from URL with ngRoute . It means that you will need to include angular-route.js in your application as a dependency. More information how to do this on official ngRoute documentation.

The solution for the question:

// You need to add 'ngRoute' as a dependency in your app
angular.module('ngApp', ['ngRoute'])
    .config(function ($routeProvider, $locationProvider) {
        // configure the routing rules here
        $routeProvider.when('/backend/:type/:id', {
            controller: 'PagesCtrl'
        });

        // enable HTML5mode to disable hashbang urls
        $locationProvider.html5Mode(true);
    })
    .controller('PagesCtrl', function ($routeParams) {
        console.log($routeParams.id, $routeParams.type);
    });

If you don't enable the $locationProvider.html5Mode(true);. Urls will use hashbang(/#/).

More information about routing can be found on official angular $route API documentation.

Side note: This question is answering how to achieve this using ng-Route however I would recommend using the ui-Router for routing. It is more flexible, offers more functionality, the documentations is great and it is considered the best routing library for angular.

Answer 3

ex: url/:id

var sample= app.controller('sample', function ($scope, $routeParams) {
  $scope.init = function () {
    var qa_id = $routeParams.qa_id;
  }
});

Answer 4

In your route configuration you typically define a route like,

.when('somewhere/:param1/:param2')

You can then either get the route in the resolve object by using $route.current.params or in a controller, $routeParams. In either case the parameters is extracted using the mapping of the route, so param1 can be accessed by $routeParams.param1 in the controller.

Edit: Also note that the mapping has to be exact

/some/folder/:param1

Will only match a single parameter.

/some/folder/:param1/:param2 

Will only match two parameters.

This is a bit different then most dynamic server side routes. For example NodeJS (Express) route mapping where you can supply only a single route with X number of parameters.

Answer 5

Just inject the routeParams service:

http://docs.angularjs.org/api/ngRoute.$routeParams

Answer 6

You could inject $routeParams to your controller and access all the params that where used when the route was resolved.

E.g.:

// route was: app.dev/backend/:type/:id

function MyCtrl($scope, $routeParams, $log) {
    // use the params
    $log.info($routeParams.type, $routeParams.id);
};

See angular $routeParams documentation for further information.
