Troubleshooting the issue of AngularJs location.path not successfully transferring parameters

My page has a Login section.

Login.html

<ion-view view-title="Login" name="login-view">
  <ion-content class="padding">
      <div class="list list-inset">
          <label class="item item-input">
              <input type="text" placeholder="Username" ng-model="data.username">
          </label>
          <label class="item item-input">
              <input type="password" placeholder="Password" ng-model="data.password">
          </label>
      </div>
      <button class="button button-block button-calm" ng-click="login()">Login</button>
  </ion-content>
</ion-view>

Upon clicking the login button, the login() method is executed.

LoginCtrl controller.

.controller('LoginCtrl', function ($scope, LoginService, $ionicPopup, $state, $location, $http) {
  $scope.login = function () {
    $http({
      method: 'GET',
      url: 'http://localhost:49431/api/values/GetUserInfo?username=' + $scope.data.username + '&password=' + $scope.data.password + ''
    }).then(function successCallback(response) {
      if (response.data.Status == true) { // Success
        $location.path('/HomePage/').search({ id: '1' }); // Issue here
      } else { // Fail
        var alertPopup = $ionicPopup.alert({
          title: 'Login failed!',
          template: 'Username or password is incorrect!'
        });
        $scope.data.username = "";
        $scope.data.password = "";
      }
    }, function errorCallback(response) {
      alert("error");
    });
  }
})

The code snippet

$location.path('/HomePage/').search({ id: '1' }); 

is intended to pass the id parameter to the HomePage.Html page. However, the parameter is not passed and the page is not redirected. In short, the location path is not functioning.

HomePageCtrl controller

.controller('HomePageCtrl', function ($scope, HomePageService, $state, $location, $cordovaCamera, $stateParams, $routeParams) {
    alert($routeParams.id + $stateParams.id);
}

app.js

.config(function ($stateProvider, $urlRouterProvider) {
  $stateProvider
    .state('HomePage', {
      url: '/HomePage',
      templateUrl: 'templates/HomePage.html',
      controller: 'HomePageCtrl'
    })
    .state('login', {
      url: '/login',
      templateUrl: 'templates/Login.html',
      controller: 'LoginCtrl'
    });
  $urlRouterProvider.otherwise('/login');
});

Question:

How can I successfully pass a parameter to the HomePageCtrl controller from the LoginCtrl controller using $location.path?

Any assistance would be greatly appreciated.

Thank you.

Answer №1

What is the benefit of using $state over $location?

App.js :

 .state('HomePage', {
             url: '/HomePage/:id',
             templateUrl: 'templates/HomePage.html',
             controller: 'HomePageCtrl'
  })

LoginCtrl:

.controller('LoginCtrl', function ($scope, LoginService, $ionicPopup, $state, $location, $http) {

           $scope.login = function () {

            $http({
                method: 'GET',
                url: 'http://localhost:49431/api/values/GetUserInfo?username=' + $scope.data.username + '&password=' + $scope.data.password + ''
            }).then(function successCallback(response) {

                if (response.data.Status == true) { // Success

                    $state.go('HomePage',{id:'1'})

                }
                else { // Fail
                    var alertPopup = $ionicPopup.alert({
                        title: 'Login failed!',
                        template: 'Username or password is incorrect!'
                    });

                    $scope.data.username = "";
                    $scope.data.password = "";
                }

            }, function errorCallback(response) {
                alert("error");
            });
    }
    })

HomeCtrl :

.controller('HomePageCtrl', function ($scope, HomePageService, $state, $location, $cordovaCamera, $stateParams, $routeParams) {

    alert($stateParams.id);
}

While I have not personally experimented with using location.path, typically, you must define parameters in the URL within the $stateProvider:

$stateProvider
 .state('Homepage', {
     url: '/Homepage',
     templateUrl: 'templates/Homepage.html',
     controller: 'HomepageCtrl'
 })
 .state('signin', {
     url: '/signin/:username/:password',
     templateUrl: 'templates/Signin.html',
     controller: 'SigninCtrl'
 })

Afterwards, you can access these parameters in your controller using $stateParams.username...
