Angular Not Posting to URI - javascript

My angular code is not posting to the api when I enter data in a form even though my api has been proven to work and takes curl CRUD requests. The register function is called from my partial, then Register controller uses the user service and register function to post form the model to the api
user service
(function () {
'use strict';
angular
.module('app')
.factory('UserService', UserService);
UserService.$inject = ['$http'];
function UserService($http) {
var service = {};
service.GetAll = GetAll;
service.GetById = GetById;
service.GetByUsername = GetByUsername;
service.Create = Create;
service.Update = Update;
service.Delete = Delete;
return service;
function GetAll() {
return $http.get('https://me.com/api/users/').then(handleSuccess, handleError('Error getting all users'));
}
function GetById(id) {
return $http.get('https://me.com/api/users/' + id).then(handleSuccess, handleError('Error getting user by id'));
}
...
function Create(user) {
return $http.post('https://me.com/api/users', user).then(handleSuccess, handleError('Error creating user'));
}
.....

Register controller/function
(function () {
'use strict';
angular
.module('app')
.controller('RegisterController', RegisterController);
RegisterController.$inject = ['UserService', '$location', '$rootScope', 'FlashService'];
function RegisterController(UserService, $location, $rootScope, FlashService) {
var vm = this;
vm.register = register;
function register() {
vm.dataLoading = true;
UserService.Create(vm.user)
.then(function (response) {
if (response.success) {
FlashService.Success('Registration successful', true);
$location.path('/login');
} else {
FlashService.Error(response.message);
vm.dataLoading = false;
}
});
return false;
}
}
})();

How did you assign your controller to the view? Did you use the controller as syntax? For example:
<div ng-controller="RegisterController as vm">your view here </div>
You are assigning the register function to vm but the vm is just a local variable in the controller function so angular is not able to use its functions in view.
Assigning this to local vm variable is a good practice, better than using $scope everywhere, but it's still just a local variable inside the controller function's scope. If you assign your controller to view and rename your controller (<div ng-controller="RegisterController as vm">), then it will work.

sessionStorage.restorestate = false;
}
});
//let everthing know that we need to save state now.
window.onbeforeunload = function (event) {
$rootScope.$broadcast('savestate');
};
};
UPDATE: On Submit, When I check the response in network tab in dev tools, I do not see the submitted values. All I see is the markup.
In your template, the name of the method is saveform:
ng-submit="saveform()"
But in your controller, it's save:
$scope.save = function() { ... }
Rename it to saveform:
$scope.saveform = function() { ... }

ReferenceError: fblogin is not defined at new LoginController - Angular

I'm trying to add a simple login via facebook but I'm having some trouble.
.js file:

Make sure you have the correct APP id and the redirect url set in the app settings.
.config([
'FacebookProvider',
function(FacebookProvider) {
var myAppId = '1367223633302978';
FacebookProvider.init(myAppId);
}
])

$location error in angularJS

I have a master controller and I would like to set up the login page to take me to "/tables" path if username=admin and password=admin, however I am getting this error everytime I try to login
TypeError: Cannot read property 'path' of undefined
I added $location in the controller and in the login function but nothing changed keep getting same error. If I take $location out I get this error
ReferenceError: $location is not defined
Not sure what to do there. Any help is appreciated. Here is my code
angular
.module('RDash')
.controller('MasterCtrl', ['$scope', '$cookieStore', MasterCtrl]);
function MasterCtrl($scope, $cookieStore, $location) {
/**
* Sidebar Toggle & Cookie Control
*/
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>
You missed to inject $location in your dependency array of MasterCtrl
Code
angular
.module('RDash')
.controller('MasterCtrl', ['$scope', '$cookieStore', '$location', MasterCtrl]);
//^^^^^^^^
function MasterCtrl($scope, $cookieStore, $location) {
Also you need to remove $scope.login parameter $location which is killing the service $location variable existance which is inject from the controller.
$scope.login = function ()
You are not passing any $location to login function hence it's undefined and shadows outer $location local variable. Correct code should be:
$scope.login = function () {
if ($scope.credentials.username !== "admin" && $scope.credentials.password !== "admin") {
alert("you are not the admin");
} else {
$location.path('/tables');
}
};

angularjs JavaScript inheritance, fail to bind data from view to a controller

what am trying to do is to get data from the form use it in my controller in HTTP post call but it's not working
I know i might have problem with inheritance of scopes but icant solve it.
here is my controller code:
.controller('SignUpCtrl', function($scope, $http, $state) {
$scope.submit = function() {
var url = 'http://localhost:3000/register';
var user = {
email: $scope.email,
password: $scope.password,
};
console.log($scope.user);
$http.post(url, user)
.success(function(res){
console.log('You are now Registered');
//$state.go('app.items');
})
.error(function(err){
console.log('Could not register');
// $state.go('error');
});
};
})
Here is the code of my Template:
<form name="register">
<div class="list">
<label class="item item-input no-border">
<input name="fullname" type="text" ng-model="fullname" placeholder="Full Name" required="">
</label>
<label class="item item-input">
<input name="email" type="email" ng-model="user.email" placeholder="Email" required="">
</label>
<p class="blue-font" ng-show="register.email.$dirty && register.email.$invalid">Please Write valid Email.</p>
<label class="item item-input">
<input name="password" type="password" ng-model="user.password" placeholder="Password" required="">
</label>
<button ng-click="submit();" ng-disabled="register.$invalid" type="submit" class="button signup-btn sharb-border white-font blue-bg-alt border-blue-alt ">
Sign Up
</button>
</div>
</form>
Note: i tried the ng-submit its not really the problem
Inside the controller.
.controller('SignUpCtrl', function($scope, $http, $state) {
$scope.user = {
email: '',
password: ''
};
$scope.submit = function() {
And this
var user = {
email: $scope.user.email,
password: $scope.user.password
};
Also drop the ; in ng-click
<button ng-click="submit()" ...>
Try to use rootScope (docs.angularjs.org/$rootScope").

Can't access form inside AngularJS controller

Can't access form variable from my controller, when i try to access it by $scope.locationForm i've got 'undefined', but when i call console.log($scope) i can see in console there have loactionForm.
My HTML code
<div ng-controller="LocationsController as ctrl">
<form class="form-inline" name="locationForm">
<div class="form-group">
<!-- <div class="input-group"> -->
<label for="location-name">Название населенного пункта</label>
<input required
name="name"
ng-model="ctrl.location.name" type="text" class="form-control" id="location-name" placeholder="Название населенного пункта">
<label for="location-name">Район</label>
<select required
name="region_id"
ng-model="ctrl.location.region_id"
ng-options="region.id as region.name for region in ctrl.regions" class="form-control" placeholder="Название района"></select>
<input ng-click="ctrl.save()"
ng-disabled="locationForm.$invalid" type="submit" class="btn btn-default" value="Cохранить">
<a class="btn btn-default" ng-click="ctrl.reset()" ng-show="locationForm.$dirty">Сброс</a>
<!-- </div> -->
</div>
</form>
My Controller code:
function LocationsController($scope, Location, Region, $q) {
var lc = this,
l_index;
lc.form ={};
lc.regions = lc.locations = [];
lc.regions = Region.query();
lc.regions.$promise.then(function(data) {
lc.locations = Location.query();
});
lc.getRegion = function (id) {
return lc.regions.filter(function(obj) {
return obj.id == id;
})[0].name;
};
console.log($scope);
// console.log($scope.locationForm);
lc.reset = function () {
lc.location = new Location;
}
lc.reset();
};
The problem is when the LocationsController is initialized the form element is not yet compiled. So one possible hack is to use a timeout like
function LocationsController($scope, Location, Region, $q, $timeout) {
//then later
$timeout(function(){lc.reset();})
}
