angularjsHow do I use path variables in AngularJS?

Path variables in AngularJS are used to store parameters in the URL. These parameters can be used to pass information to the controller and can be retrieved using the $routeParams service.

Example code

var app = angular.module('myApp', ['ngRoute']);

app.config(function($routeProvider) {
        .when('/users/:userId', {
            templateUrl: 'user.html',
            controller: 'UserController'

app.controller('UserController', function($scope, $routeParams) {
    $scope.userId = $routeParams.userId;

In the above example, we define a route with a path variable userId and use the $routeParams service to get the value of userId in the controller.

Code explanation

  • var app = angular.module('myApp', ['ngRoute']);: Declares a new AngularJS application.
  • $routeProvider.when('/users/:userId', {...}): Defines a route with a path variable userId.
  • $scope.userId = $routeParams.userId;: Retrieves the value of userId using the $routeParams service.
