Recently, I encountered an issue with my form while implementing Angular validation. The goal was to ensure that the input fields were not left blank by using an if statement.
However, upon testing the form, I received the following error message:
Cannot read property 'name' of undefinedIt appears that the code is unable to read the name attribute of an empty <input> tag. The validation function works perfectly when filling in the 'name' field, but not for other fields such as 'rating' and 'reviewText'. My approach involved checking if these fields were filled out using an if statement. Here's a snippet of the HTML and Angular code below:
reviewModal.view.html (abridged version)<div class="modal-content">
<div role="alert" ng-show="vm.formError" class="alert alert-danger">{{ vm.formError }}</div>
<form id="addReview" name="addReview" role="form" ng-submit="vm.onSubmit()" class="form-horizontal">
<label for"name" class="col-xs-2 col-sm-2 control-label">Name</label>
<div class="col-xs-10 col-sm-10">
<input id="name" name="name" ng-model="vm.formData.name" class="form-control">
</div>
<button type="submit" class="btn btn-primary">Submit review</button>
</form>
</div>
reviewModal.controller.js
(function() {
angular
.module('loc8rApp')
.controller('reviewModalCtrl', reviewModalCtrl);
reviewModalCtrl.$inject = ['$uibModalInstance', 'locationData'];
function reviewModalCtrl($uibModalInstance, locationData) {
var vm = this;
vm.locationData = locationData;
vm.onSubmit = function() {
vm.formError = "";
if(!vm.formData.name || !vm.formData.rating || !vm.formData.reviewText) {
vm.formError = "All fields required, please try again";
return false;
} else {
console.log(vm.formData);
return false;
}
};
vm.modal = {
cancel : function() {
$uibModalInstance.dismiss('cancel');
}
};
}
})();
locationDetail.controller.js
(function() {
angular
.module('loc8rApp')
.controller('locationDetailCtrl', locationDetailCtrl);
locationDetailCtrl.$inject = ['$routeParams', '$uibModal', 'loc8rData'];
function locationDetailCtrl($routeParams, $uibModal, loc8rData) {
var vm = this;
vm.locationid = $routeParams.locationid;
loc8rData.locationById(vm.locationid)
.success(function(data) {
vm.data = { location: data };
vm.pageHeader = {
title: vm.data.location.name
};
})
.error(function(e) {
console.log(e);
});
vm.popupReviewForm = function() {
var modalInstance = $uibModal.open({
templateUrl: '/reviewModal/reviewModal.view.html',
controller: 'reviewModalCtrl as vm',
resolve : {
locationData : function() {
return {
locationid : vm.locationid,
locationName : vm.data.location.name
};
}
}
});
};
}
})();
