The route parameters are malfunctioning

Question

The route parameters are malfunctioning

I've managed to get basic routing functionality working, but I'm encountering an issue when trying to include parameters in my routes. When I attempt to access routes with params, nothing appears inside my ngview.

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

myApp.config(function($routeProvider) {

    $routeProvider

    .when('/', {
        templateUrl: 'pages/main.html',
        controller: 'mainController'
    })

    .when('/second/:num', {
        templateUrl: 'pages/second.html',
        controller: 'mainController'
    })

});

myApp.controller('mainController',
    ['$scope', '$log', '$routeParams', function($scope, $log, $routeParams) {
    $scope.name = "Chris";
    alert($routeParams);
    $scope.num = $routeParams.num;
    $log.info($scope.num)
}]);

Whenever I try to navigate to /second/:num, nothing shows up in my ngview. Strangely, accessing either / or /second works perfectly fine.

Make sure to verify the controller in second.html page to ensure it has been properly added. It is recommended to always utilize different controllers for each template.

The preferred method is using stateProvider as it is easier and more flexible compared to routeProvider. Although both serve the same purpose, stateProvider tends to be more practical.

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

myApp.config(function($stateProvider) {

  $stateProvider
    .state('/', {
    templateUrl: 'pages/main.html',
    controller: 'mainController'
  })

  .state('/second/:num', {
    templateUrl: 'pages/second.html',
    controller: 'mainController'
  })

});
myApp.controller('mainController', ['$scope', '$log', '$stateParams', function($scope, $log, $stateParams) {
  $scope.name = "Chris";
  alert($stateParams);
  $scope.num = $stateParams.num;
  $log.info($scope.num)
}]);

It seems like there may be an issue with how you're specifying the path to your templates or possibly an error in your console log. Here is a snippet of your code, including the html files in ng-templates:

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

myApp.config(function($routeProvider) {

  $routeProvider

  .when('/', {
    templateUrl: 'main.html',
    controller: 'mainController'
  })

  .when('/second/:num', {
    templateUrl: 'second.html',
    controller: 'mainController'
  })

});
myApp.controller('mainController', ['$scope', '$location', '$log', '$route', '$routeParams', function($scope, $location, $log, $route, $routeParams) {
  $scope.name = "Chris";
  $scope.num = $routeParams.num || 'not defined';
  console.log($scope.num);
  
  $scope.goTo = function(number) {
    $location.path('/second/' + number);
  };
  $scope.route = $route.current;
  $scope.goHome = function(number) {
    $location.path('/');
  };
}]);
