What are the reasons behind the error message when adding dependencies in AngularJS?

Currently, while developing a web app and implementing routes, I encountered an issue with my ngRoute. Before adding ngRoute as a dependency to myApp, the viewproducts were functioning properly. However, after integrating ngRoute, I am now seeing {{product.name}} {{product.company}} instead of the actual values.

Module CODE :

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

    myApp.config(function($routeProvider){
        $routeProvider.
            when('/addproduct', {
                  templateUrl:'addproduct.html',
                  controller:'myController'
             })
});

Controller CODE :

myApp.controller("myController",function($scope,$http){
    $scope.insertData = function(){
        $http.post("addProduct.php",{'pname': $scope.productname,'company': $scope.company,'price': $scope.price,'quantity':$scope.quantity})
        .success(function(data,status,headers,config){

           $scope.successMessage = "Inserted Successfuly!"; 
        });
    }

});

HTML CODE:

<!DOCTYPE html>
<html ng-app="myApp">
<!-- Other HTML elements remain unchanged -->
</body>
<!-- Additional script sources added in this section -->
</html>

Answer №1

It appears that you are possibly redefining your module. Is there a chance that the following code exists elsewhere in your project?

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

If so, calling the module again with brackets could result in redefining the original module. Consider adding the ngRoute dependency to the initial module definition and removing the brackets from the configuration call. It should then resemble the example below.

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

Answer №2

The sequence of your scripts is crucial! Make sure the file where you define your angular module app comes after the angular-route file.

Revised:

<script src="js/angular/angular.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.1/angular-route.min.js"></script>
<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/data.js"></script>

<script src="main.js"></script>
<script src="angularkhan.js"></script>
