Angular js scope between directive and controllers - angularjs

I have to show user login page in pop up and have to validate user name and password with the server by using angular js. I create one app model file, and one controller, service and one directive. My code looks like bellow,
app.js
angular.module('mint', ['ngAnimate', 'toastr']);
mycontroller.js
angular.module('mint').controller(
'headercontroller',
[
'$scope',
'headerservice',
'toastr',
function($scope, headerservice, toastr) {
$scope.showModal = false;
$scope.toggleModal = function() {
$scope.showModal = !$scope.showModal;
};
$scope.userSignin = function(){
$scope.userloginbtn = false;
if($scope.signin_form.$valid){ //Error on this line signin_form is undefine. using $valid for undefine
var record = {};
angular.extend(record, $scope.signinForm);
console.log(record);
}else {
$scope.signin_form.submitted = false;
$scope.userloginbtn = true;
}
};
} ]);
my directive.js file is
angular
.module('mint')
.directive(
'modal',
function() {
return {
template : '<div class="modal fade">'
+ '<div class="modal-dialog">'
+ '<div class="modal-content">'
+ '<div class="modal-header">'
+ '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>'
+ '<h4 class="modal-title"><span><i class="fa fa-user"></i> {{ title }}</span></h4>'
+ '</div>'
+ '<div class="modal-body" ng-transclude></div>'
+ '</div>' + '</div>' + '</div>',
restrict : 'E',
transclude : true,
replace : true,
scope : true,
link : function postLink(scope, element, attrs) {
scope.title = attrs.title;
scope.$watch(attrs.visible, function(value) {
if (value == true)
$(element).modal('show');
else
$(element).modal('hide');
});
$(element).on('shown.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = true;
});
});
$(element).on('hidden.bs.modal', function() {
scope.$apply(function() {
scope.$parent[attrs.visible] = false;
});
});
}
};
});
My html file looks like
<!DOCTYPE html>
<html lang="en" ng-app="mintmygold">
<body>
<div class="container-fluid ban_bg"
ng-controller="headercontroller">
<div class="but_bg">
<button type="button" class="btn btn-default btn_sin" ng-click="toggleModal()">
<span><i class="fa fa-key"></i> Sign In</span>
</button>
</div>
<modal title="Login" visible="showModal">
<form role="form" name="signin_form" class="signup_form" novalidate
ng-model="signin_form">
<div class="form-group">
<p class="infoMsg" ng-model="signinform_info">Please fill in your login credentials:</p>
</div>
<div class="form-group">
<label for="email">Email address</label>
<input ng-model="signinForm.userEmail" name="userEmail" type="email" class="form-control" id="email" placeholder="Enter email" required />
<div
ng-show="signin_form.$submitted || signin_form.userEmail.$touched">
<span ng-show="signin_form.userEmail.$error.required">Enter your
email.</span> <span ng-show="signin_form.userEmail.$error.email">This
is not a valid email.</span>
</div>
</div>
<div class="form-group">
<label for="password">Password</label>
<input ng-model="signinForm.userPassword" name="userPassword" type="password" class="form-control" id="password" placeholder="Password" required />
<div
ng-show="signin_form.$submitted || signin_form.userPassword.$touched">
<span ng-show="signin_form.userPassword.$error.required">Enter your
password.</span>
</div>
</div>
<button ng-disabled="signin_form.$invalid || !userloginbtn" ng-model="signin" ng-click="userSignin()" type="submit" class="btn btn-primary">Submit</button>
</form>
</modal>
</div></body></html>
Now i can show the popup when click on sign in button. When i submit the form i couldn't get the values of email and password values from the pop up form in controller. what is my mistake of using the scope. Please any one help me.

With a quick overlook, it seems a silly mistake. Change your lines
From
angular.module('mint', ['ngAnimate', 'toastr']);
To
angular.module('mintmygold', ['ngAnimate', 'toastr']);

You are using scope: true which means your directive is creating a child scope and inheriting the properties from its parent.
Therefore any property you define in the directive scope does not exists on you controller scope.
Changing form name=signin_form
for form name=$parent.signin_form or scope: false should fix the problem
I didn't test this though. And it's not a good solution.
I would probably create a service that launches the pop-up and returns a promise that gets resolved/rejected accordingly.
app.js
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope, modal) {
$scope.launch = function(){
modal.show().then(function(user){
console.log(user)
}, function(err){
console.log(err)
});
}
});
app.factory('modal', ["$document", "$compile", "$rootScope", "$templateCache", "$timeout", "$q",
function ($document, $compile, $rootScope, $templateCache, $timeout, $q) {
var $body = $document.find('body');
return {
show: function(){
var defer = $q.defer(),
child = $rootScope.$new();
child.user = {};
child.close = function(){
defer.reject('canceled');
tpl.remove();
}
child.submit = function(){
defer.resolve(child.user);
tpl.remove();
}
var tpl = angular.element($templateCache.get('modal.html'));
$compile(tpl)(child);
$body.append(tpl);
return defer.promise;
}
};
}]);
index.html
<script type="text/ng-template" id="modal.html">
<div class="modal in" style="position: static; display: block">
<div class="modal-dialog">
<form ng-submit="submit()" class="modal-content">
<div class="modal-header">
<button type="button" class="close" ng-click="close()" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
Email: <input ng-model="user.email"></input><br>
Password: <input ng-model="user.password"></input>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" ng-click="close()">Close</button>
<button type="submit" class="btn btn-primary">Sign in</button>
</div>
</form>
</div>
</div>
</script>
<button type="button" ng-click="launch()" class="btn btn-primary">Show modal</button>

This is just a proof of concept. I think is enough to get you started. I'd strongly recommend to checkout UI Bootstrap and the way the implement their modal

ui bootstrap modal Unknown provider $uibModalInstanceProvider

I am stuck again with my angular ui-bootstrap modal window.
I have header which contains
<a ng-click="openLoginModal()">Zaloguj</a>
and have controller named headerCtrl.js
app.controller('HeaderCtrl', ['$scope', '$uibModal', 'ApiService', function($scope, $uibModal, ApiService) {
"use strict";
$scope.allGames = ApiService.GetGames();
$scope.openLoginModal = function(size, parentSelector) {
var parentElem = parentSelector ?
angular.element($document[0].querySelector('.modal-login' + parentSelector)) : undefined;
var modalInstance = $uibModal.open({
animation: $scope.animationsEnabled,
ariaLabelledBy: 'modal-header',
ariaDescribedBy: 'modal-body',
templateUrl: 'app/views/modals/LoginModal.html',
controller: 'LoginModalCtrl',
controllerAs: '$ctrl',
backdropClass: "modal-backdrop",
size: size,
backdrop: true,
appendTo: parentElem,
resolve: {
items: function() {
return $scope.items;
}
}
});
};
}]);
After I click "Zaloguj" which starts openLoginModal method modal shows but doesn't have any content and in cosole shows error:

$ctrl.cancel = function() {

};
$ctrl.login = function() {
authenticationService.login($ctrl.loginData)
.then(function(data) {
$uibModalInstance.close();
$location.url("/");
}, function(error) {

};
}]);

You need to include $uibModal as a parameter to the controller function just like you have done for $scope.

Datepicker in Angular ui modal not opening

I have a datepicker within a form in my modal. The datepicker is not opening no matter what I try. My code is :
//In my parent controller - Called on button click
$scope.openModal = function(indx){
var modalInstance = $modal.open({
animation:true,
templateUrl:'myModal.html',
controller: 'MyModalController'
});
};
//In MyModalController
$scope.open = function(){
$scope.opened = true;
console.log('Opened is : ' + $scope.opened);
};
//Modal view file myModal.html
<input type="text" class="form-control" datepicker-popup="dd.MMMM.yyyy" ng-model="obj.startDate" is-open="$parent.opened" min-date="minDate" max-date="'2015-06-22'" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open(evt)">Close</button>
</span>
This question has been asked before, but the solutions given are not working for me. I have already tried everything suggested here:
ui.bootstrap.datepicker is-open not working in modal
https://github.com/angular-ui/bootstrap/issues/2307
Add $event.preventDefault() and $event.stopPropagation() to your open function in your controller and make sure to pass the $event to the open function in the ng-click:
$scope.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
and in your view:
<button type="button" class="btn btn-default" ng-click="open($event)">Close</button>
Run the code snippet to see a working demo:
var app = angular.module('demo', ['ui.bootstrap', 'ngAnimate']);
app.controller('MainCtrl', ['$scope', '$modal', function($scope, $modal){
$scope.open = function () {
var modalInstance = $modal.open({
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl'
});
};
}]);
app.controller('ModalInstanceCtrl', ['$scope', '$modalInstance', function ($scope, $modalInstance) {
$scope.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
}]);

AngularJs Form validation ui-bootstrap modal

I'm trying to use a form with validation into a ui-bootstrap modal and the modal as a cancel button that just dismisses the view when clicked. The cancel is not working if there is validation errors. if I click again on the button then the modal closes. What am I possibly doing wrong?
http://plnkr.co/edit/loFUvJRfuycxd3qQwMgM?p=preview
angular.module('myApp', ['ui.bootstrap']);
angular.module('myApp').controller('TestCTRL', function ($scope,modalService) {
$scope.login = function () {
var modalOptions = {
closeButtonText: 'Cancel',
submitForm : function(form) {
if(form.$valid) {
console.log('Loggin in');
}
}
};
modalService.showModal({}, modalOptions).then(function (result) {
console.log('completed');
});
};
});
angular.module('myApp').service('modalService', function ($modal) {
var modalDefaults = {
backdrop: true,
keyboard: true,
modalFade: true,
templateUrl: 'login.html'
};
var modalOptions = {
closeButtonText: 'Close',
actionButtonText: 'OK',
headerText: 'Proceed?',
bodyText: 'Perform this action?'
};
this.showModal = function (customModalDefaults, customModalOptions) {
if (!customModalDefaults) customModalDefaults = {};
customModalDefaults.backdrop = 'static';
return this.show(customModalDefaults, customModalOptions);
};
this.show = function (customModalDefaults, customModalOptions) {
//Create temp objects to work with since we're in a singleton service

var tempModalOptions = {};
//Map angular-ui modal custom defaults to modal defaults defined in service

Thanks so much for your help.
I resolved it by setting the form to pristine before closing the modal, in the cancel action function
function _cancel()
{
$scope.newForm.$setPristine();
$modalInstance.close();
}

angularjs directive i want to create a html template with button

var ImagesApp = angular.module('Images', []);
ImagesApp.directive('fancybox', function($q, $http, $templateCache) {
return function(scope, element, attrs) {
scope.ShowFullImageByClick = function() {
var el = '<input type="submit" id="comment-btn" class="mybtn" value="Comment" ng-click="AddComment()">'
$.fancybox.open(el);
}
}
});
<div id='full-image-view' style="display: none;" fancybox>
<div id='full-image-view-left'></div>
</div>
Well, for example...
HTML page template
<body ng-controller="Ctrl">
<b>Comment</b>
<add-comment comments="comments"></add-comment>
<div ng-repeat="comment in comments">
> {{ comment }}
</div>
</body>
Directive template
<div>
<form>
<div class="input-group">
<input class="form-control"
type="text"
placeholder="Add your comment..."
ng-model="comment">
<span class="input-group-btn">
<button class="btn btn-default"
type="button"
ng-click="add()">
Add comment
</button>
</span>
</div>
</form>
</div>
JavaScript
var app = angular.module('plunker', []);
app.controller('Ctrl', function($scope) {
$scope.comments = ['comment 1','comment 2'];
});
app.directive('addComment', function() {
return {
restrict: 'E',
scope: {
comments: '='
},
controller: function($scope) {
$scope.add = function() {

$scope.comments.push($scope.comment);
$scope.comment = null;
}
};
},
templateUrl: 'add-comment-directive.html'

what is happening to my angular scope?

I am using angularstrap modal service to open a login modal on any page when login is required. I open one like this:
var scope = {'foo': 'bar'};
var myOtherModal = $modal({scope: scope, template: 'modal/login.html', show: false});
the login.html contains the modal markup but it also has a controller bound to it:
<div ng-controller="SignInController" class="modal" tabindex="-1" role="dialog">
<input ng-modal="foo"/>
In the controller code, how do I get access to the foo prop on the scope that I am passing in?
What is happening to my scope? Is a scope object created by $modal the one and the same that is used by the controller? It appears that its not the case.
What is the best way to solve this problem? (Ability to open a login dialog from anywhere and have control over its scope from the controller)
Thanks
Think of opening a modal as a function call... where you pass data in and get data back. It's not the ONLY way to approach it but I think it's a clean way to approach it.
I generally follow this pattern, giving the modal it's own controller & passing data in & getting data back by passing it into the promise:
var ModalController = function($scope, $modalInstance, input) {
$scope.input = input;
var output = {
username: "",
password: ""
};
$scope.ok = function () {
$modalInstance.close($scope.output);
};
$scope.cancel = function () {
$modalInstance.dismiss('cancel');
};
};
$scope.openModal = function(data) {
var modalInstance = $modal.open({
templateUrl: 'popupDialog.tpl.html',
controller: ['$scope', '$modalInstance', 'input', ModalController],
resolve: {
input: function() {
return data;
}
}
});
modalInstance.result.then(function(output) {
// TODO: do something with the output.username & output.password...
// call Login Service, etc.
});
};
EDIT: Adding popup html...
<form class="form-horizontal">
<div class="modal-header">
<h3>Please Log In</h3>
</div>
<div class="modal-body">
<form name="form" class="form-horizontal">
<div class="row">
<label class="col-sm-3 text-info control-label" for="inputUsername">Username</label>
<input class="col-sm-8 form-control input-sm" type="text" id="inputUsername" name="inputUsername" ng-model="output.username" />
</div>
<div class="row">
<label class="col-sm-3 text-info control-label" for="inputPassword">Password</label>
<input class="col-sm-8 form-control input-sm" type="text" id="inputPassword" name="inputPassword" ng-model="output.password" />
</div>
</form>
</div>
<div class="modal-footer">
<button class="btn btn-sm btn-primary" type="submit" ng-click="ok()">Ok</button>
<button class="btn btn-sm btn-warning" ng-click="cancel()">Cancel</button>
</div>
</form>
