AngularJs Adding Form Fields Dynamically and identification in the scope - angularjs

Question

I would like to create a form with several fields: name, last name, ... and add one or several email. The first email field is mandatory. After he should have the possibility to click on "Add email" for adding a new email address. He could add 4 others emails (5 emails in total).
The system should be verify if the format of the email is correct, display a message if necessary and register the data in a DB.
Here my controler "ctrlEditContacts" and module (app.js):
var app=angular.module('ContactsApp', ['ngRoute', 'ui.bootstrap', 'ngDialog']);
// register the interceptor as a service
app.factory('HttpInterceptor', ['$q', '$rootScope', function($q, $rootScope) {
return {
// On request success
request : function(config) {
// Return the config or wrap it in a promise if blank.
return config || $q.when(config);
},
// On request failure
requestError : function(rejection) {
//console.log(rejection); // Contains the data about the error on the request.
// Return the promise rejection.
return $q.reject(rejection);
},
// On response success
response : function(response) {
//console.log(response); // Contains the data from the response.
// Return the response or promise.
return response || $q.when(response);
},
// On response failure
responseError : function(rejection) {
//console.log(rejection); // Contains the data about the error.
//Check whether the intercept param is set in the config array.
//If the intercept param is missing or set to true, we display a modal containing the error
if (typeof rejection.config.intercept === 'undefined' || rejection.config.intercept)
{
//emitting an event to draw a modal using angular bootstrap
$rootScope.$emit('errorModal', rejection.data);
}
// Return the promise rejection.
return $q.reject(rejection);
}
};
}]);
app.config(function($routeProvider, $httpProvider, ngDialogProvider){
$httpProvider.defaults.cache = false;
if (!$httpProvider.defaults.headers.get) {
$httpProvider.defaults.headers.get = {};
}
// disable IE ajax request caching
$httpProvider.defaults.headers.get['If-Modified-Since'] = '0';
ngDialogProvider.setDefaults({
className: 'ngdialog-theme-default',
plain: false,
showClose: true,
closeByDocument: true,
closeByEscape: true,
appendTo: false,
preCloseCallback: function () {
console.log('default pre-close callback');
}
});
.when('/edit-contacts/:contactId',
{
templateUrl: 'template/manageContact.html',
controller: 'ctrlEditContacts'
})
.otherwise({redirectTo:'/all-contacts'});
});
app.factory('httpInterceptor', function ($q, $rootScope, $log) {
var numLoadings = 0;
return {
request: function (config) {
numLoadings++;
// Show loader
$rootScope.$broadcast("loader_show");
return config || $q.when(config)
},
response: function (response) {
if ((--numLoadings) === 0) {
// Hide loader
$rootScope.$broadcast("loader_hide");
}
return response || $q.when(response);
},
responseError: function (response) {
if (!(--numLoadings)) {
// Hide loader
$rootScope.$broadcast("loader_hide");
}
return $q.reject(response);
}
};
})
app.controller('ctrlEditContacts', function ($scope, $routeParams, ContactService){
// Sort of requests table
$scope.champTri = null;
$scope.triDescendant = false;
$scope.SortPersons = function(champ) {
if ($scope.champTri == champ) {
$scope.triDescendant = !$scope.triDescendant;
} else {
$scope.champTri = champ;
$scope.triDescendant = false;
}
}
$scope.cssChevronsTri = function(champ) {
return {
glyphicon: $scope.champTri == champ,
'glyphicon-chevron-up' : $scope.champTri == champ && !$scope.triDescendant,
'glyphicon-chevron-down' : $scope.champTri == champ && $scope.triDescendant
};
}
// MANAGE THE EMAILS
$scope.emails = [
{
}];
$scope.log = function() {
console.log($scope.emails);
};
$scope.add = function() {
var dataObj = {email:''};
$scope.emails.push(dataObj);
}
$scope.contact={};
if($routeParams.contactId){
$scope.title="Edit the contact";
}
// GET DATA FROM THE DB ABOUT THE CONTACT
ContactService.loadPersonById($routeParams.contactId).success(function(contact){
$scope.contact.ID = contact[0].ID;
$scope.contact.LASTNAME = contact[0].LASTNAME;
$scope.contact.FIRSTNAME = contact[0].FIRSTNAME;
$scope.contact.EMAIL = contact[0].EMAIL;
$scope.contact.EMAIL_1 = contact[0].EMAIL_1;
$scope.contact.EMAIL_2 = contact[0].EMAIL_2;
$scope.contact.EMAIL_3 = contact[0].EMAIL_3;
$scope.contact.EMAIL_4 = contact[0].EMAIL_4;
});
$scope.submitForm = function(contact){
console.log(contact);
if($scope.ContactForm.$valid){
ContactService.updatePerson(contact, $routeParams.contactId).success(function(){
/*$scope.ContactForm.$setPristine();
$scope.contact= null;*/
alert('Person updated successfully');
window.location="#/view-contacts/" + $scope.contact.ID;
});
}
};
});
Here my factory (appService.js)
app.factory('ContactService', function($http){
var factory={};
factory.loadPersonById=function(id){
return $http.get('http://myapp/contacts.cfc?method=loadPersonById&idPerson=' + id);
};
factory.updatePerson=function(objContact,id){
return $http.get('http://myapp/contacts.cfc?method=updatePerson&contactid=' + id + '&jsStruct=' + JSON.stringify(objContact))
};
return factory;
})
The function in the backend (server) retrieves the parameter objContact sent by the backend and executes correctly the query (it's working)
Here my view (manageContact.html)

The value of the EMAILS (EMAIL_1, EMAIL_2, EMAIL_3, ... is not displayed in the form if there is defined.
I tried to put contact.EMAIL_$index or contact.EMAIL_[$index] or contact.EMAIL_[key] but it's not working.
Could you please help me ?
Thanks for your support

In your HTML substitute
ng-model="contac.EMAIL_$index with
ng-model="contact['EMAIL_'+$index]"
and in your controller check push emails fore each email in your answer of the service
example:
ContactService.loadPersonById($routeParams.contactId).then(function(contact){
for(var i = 0; i < 5; i++){
$scope.emails.push({});
}// i add this to tell we have 5 mails
$scope.contact.ID = contact[0].ID;
$scope.contact.LASTNAME = contact[0].LASTNAME;
$scope.contact.FIRSTNAME = contact[0].FIRSTNAME;
$scope.contact.EMAIL = contact[0].EMAIL;
$scope.contact.EMAIL_1 = contact[0].EMAIL_1;
$scope.contact.EMAIL_2 = contact[0].EMAIL_2;
$scope.contact.EMAIL_3 = contact[0].EMAIL_3;
$scope.contact.EMAIL_4 = contact[0].EMAIL_4;
});
