Resolving Challenges with AngularJS Form Validation and Submission

I am currently working on a project using AngularJS where the user can activate their account, input their data, and submit JSON data upon completion.

My Goal:
When the user submits valid user data (within the JSON data), they should be redirected to '/form/'. If the data is invalid, display an error message saying 'Invalid Account'.

Current Challenges:
1. If the user enters the correct Membership and Activation number first, they are redirected to '/form/'. However, if the user enters incorrect details first and then correct details later, the redirect does not work.
2. I attempted to implement an invalid alert using an if-else statement, but multiple alerts were triggered simultaneously. I am unsure why this is happening.

I am working on this project on Plnkr, and I would appreciate any assistance and guidance in the right direction. Thank you.

  $scope.findMembership = function() {
    angular.forEach($scope.membershipData.membershipNumber, function(value, key) {
      if (key === $scope.membershipValue && value[0].activationNumber === $scope.activationValue) {
        $location.path("/form/");
      }
    });
  };

Update

formCtrl.controller('activation', function($scope, $location, $rootScope) {
  var normalized = Object.keys($scope.membershipData.membershipNumber).map(function(k) {
    return { key : k, val : $scope.membershipData.membershipNumber[k][0].activationNumber }
  });

  normalized = [
    {"key":"541","val":"541X"},
    {"key":"4692","val":"4692X"},
    {"key":"45165","val":"45165X"},
    {"key":"5464565","val":"5464565X"},
    {"key":"54645651","val":"54645651X"},
    {"key":"D4554160N","val":"D4554160NX"}
  ]

  $scope.findMembership = function() {
      if (normalized.some(function(o) {
        return o.key == $scope.membershipValue && o.val == $scope.activationValue
      })) $location.path("/form/")
  }
});

Answer №1

If you're experiencing issues, consider updating your otherwise block to the following:

    otherwise({
  templateUrl: 'view/activation.html',
  controller: 'activation'
});

It's possible that the redirect is causing the app to struggle in locating the correct template. Also, it might be best to refrain from using the $location.path() method within the angular.forEach loop. Consider normalizing the data into a true array to utilize Array.some() instead.

You could try something similar to this:

var normalized = Object.keys($scope.membershipData.membershipNumber).map(function(k) {
  return { key : k, val : $scope.membershipData.membershipNumber[k][0].activationNumber }
});

/*
  normalized = [
    {"key":"541","val":"541X"},
    {"key":"4692","val":"4692X"},
    {"key":"45165","val":"45165X"},
    {"key":"5464565","val":"5464565X"},
    {"key":"54645651","val":"54645651X"},
    {"key":"D4554160N","val":"D4554160NX"}
  ]
*/

$scope.findMembership = function() {
    if (normalized.some(function(o) {
      return o.key == $scope.membershipValue && o.val == $scope.activationValue
    })) $location.path("/form/")
}
