AngularJS location service error

My goal is to configure the login page on my master controller so that when the username and password are both set to "admin", it will redirect me to the "/tables" path. However, every time I attempt to log in, I encounter the following error:

TypeError: Cannot read property 'path' of undefined

I tried adding $location to both the controller and the login function, but the error persists. If I remove $location, I get this error instead:

ReferenceError: $location is not defined

I'm unsure of what steps to take next. Any assistance would be greatly appreciated. Below is my code snippet:

 angular
    .module('RDash')
    .controller('MasterCtrl', ['$scope',  '$cookieStore', MasterCtrl]);

function MasterCtrl($scope, $cookieStore, $location) {
    var mobileView = 992;

    $scope.getWidth = function() {
        return window.innerWidth;
    };

    $scope.login = function($location) {
        if($scope.credentials.username !== "admin" && $scope.credentials.password !== "admin") {
            alert("you are not the admin");
        }
        else{
            $location.path('/tables');
          }

      };
}

login.html:

<div ng-controller="MasterCtrl">
<form >
  <div class="jumbotron" class="loginForm">
  <div class="form-group" id="loginPageInput">
    <label for="exampleInputEmail1">User Name</label>
    <input type="text" class="form-control" id="exampleInputEmail1" placeholder="Enter Username" ng-model="credentials.username">
  </div>
  <div class="form-group" id="loginPageInput">
    <label for="exampleInputPassword1">Password</label>
    <input type="password" class="form-control" id="exampleInputPassword1" placeholder="Password" ng-model="credentials.password">
  </div>
  <div id="loginPageInput">
    <button ng-click="login()" type="submit" class="btn btn-primary btn-lg">Submit</button>
  </div>
</form>
  <div id="loginPageInput">
  <div class="wrap">
    <button ng-click="register()" class="btn btn-default" id="lefty" >Register</button>
    <p ng-click="forgotpass()" id="clear"><a>Forgot my Password</a></p>
  </div>
  </div>
</div>
</div>

Answer №1

Don't forget to include $location in the list of dependencies for your MasterCtrl

Your Code

angular
    .module('MyApp')
    .controller('MasterCtrl', ['$scope',  '$cookieStore', '$location', MasterCtrl]);
                                                          //^^^^^^^^
function MasterCtrl($scope, $cookieStore, $location) {

Also, make sure you remove the parameter $scope.login from $location, as it interferes with the injected service variable.

$scope.login = function ()

Answer №2

Make sure to pass the $location parameter to the login function in order to avoid it being undefined and causing conflicts with any outer $location local variable. The corrected code should look like this:


$scope.login = function ($location) {
    if ($scope.credentials.username !== "admin" && $scope.credentials.password !== "admin") {
        alert("you are not the admin");
    } else {
        $location.path('/tables');
    }
};
