I am facing a challenge with AngularJS where I am unable to navigate between pages using the

I'm having issues with my route file app.js. Whenever I click on any link or button, it redirects me to books.html. What could be the mistake I'm making?

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

myApp.config(['$routeProvider' , function ($routeProvider) {
    $routeProvider
        .when('/', {
            controller: 'BooksController',
            templateUrl: '/views/books.html'
        })
        .when('/books', {
            controller: 'BooksController',
            templateUrl: '/views/books.html'
        })
        .when('/books/details/:id', {
            controller: 'BooksController',
            templateUrl: '/views/books_details.html'
        })
        .when('/books/add', {
            controller: 'BooksController',
            templateUrl: '/views/add_book.html'
        })
        .when('/books/edit/:id', {
            controller: 'BooksController',
            templateUrl: '/views/edit_book.html'
        })
        .otherwise({
            redirectTo: '/'
        })
  // $locationProvider.html5Mode(true);
}]);

Every time I click on the view details button in the HTML file, it redirects me back to books.html.

<html>
    <div class="panel panel-default" ng-init="getBooks()">
      <div class="panel-heading">
        <h3 class="panel-title">Latest Books</h3>
      </div>
      <div class="panel-body">
        <div class="row">
            <div ng-repeat="book in books">
               <div class="col-md-6">
                   <div class="col-md-6">
                       <h4>{{book.title}}</h4>
                       <p>{{book.description}}</p>
                       <a class="btn btn-primary" href="#/books/details/{{book._id}}">View Details</a>
                   </div>
                   <div class="col-md-6">
                      <img class="thumbnail" ng-src="{{book.image_url}}">
                   </div>
               </div>
            </div>
        </div>
      </div>
    </div>
</html>

Could the issue be using the same controller name, BooksController?

var myApp = angular.module('myApp');

myApp.controller('BooksController', [ '$scope', '$http', '$location', '$routeParams', function ($scope, $http, $location, $routeParams) {
    $scope.getBooks = function() {

        $http.get('/api/books').then(successCallback, errorCallback);
            function successCallback(response){
                //success code
                $scope.books = response.data;
            }
            function errorCallback(error){
                //error code
                $scope.books = error;
            }   
    }
    
    $scope.getBook = function() {
        $http.get('/api/books/:id').then(successCallback, errorCallback);
            function successCallback(response){
                //success code
                $scope.book = response.data;
            }
            function errorCallback(error){
                //error code
                $scope.books = error;
            }   
    }
}]);

Could there be something wrong with the code in index.html?

Answer №1

Swap out

<a class="btn btn-primary" href="#/books/details/{{book._id}}">View Details</a>

for

<a class="btn btn-primary" ng-href="#/books/details/{{book._id}}">View Details</a>

and it should function properly. Remember to utilize ng-href when displaying a url with Angular expressions {{ }}

Answer №2

It appears that you are using hashprefix !. Therefore, your URL should also include an exclamation point after the hash (#).

 href="#!/books/details/{{book._id}}"
