Angularjs min-date max-date validation messages - angularjs

Angularjs - bootstraup UI- trying to place min-date max-date validation error messages.
but it is not working, not showing any min-date or max-date validation message.
I also tried form.offerEndDate.$error.min or form.offerEndDate.$error.max still didn't work
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="{{format}}" ng-model="form.offerEndDate" is-open="opened" min-date="minDate" max-date="'2015-06-22'" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
<div ng-show="form.offerEndDate.$dirty && form.offerEndDate.$invalid">
<span class="alert-danger" ng-show="form.offerEndDate.$error.required">
Offer End Date is required.
</span>
<span class="alert-danger" ng-show="form.offerEndDate.$error.minDate">
Min Date Error.
</span>
<span class="alert-danger" ng-show="form.offerEndDate.$error.maxDate">
Max Date Error.
</span>
</div>

Here's finally my workaround for this problem:
<div class="input-group">
<input name="endDate" class="form-control" type="text" is-open="openedEnd"
datepicker-popup="shortDate" ng-focus="openedEnd=true"
date-disabled="disabledEnd(date,mode)"
datepicker-options="dateOptions"
ng-model="offre.endDate" required="" min="endMinDate" max="endMaxDate"
ts-valid-date="" />
<span class="input-group-btn">
<button type="button" class="btn btn-default btn-default-bordered" ng-click="openEnd($event)">
<i class="fa fa-calendar"></i>
</button>
</span>
</div>
<div class="alert alert-danger"
ng-messages="formOffre.endDate.$error"
ng-if="formOffre.endDate.$dirty || vm.showOffreValidation">
<div ng-message="required">#L("RemplissezLaDateDeFin")</div>
<div ng-message="date">#L("DateIncorrecte")! {{vm.endDateInvalidMessage}} </div>
<div ng-message="invalidDate">#L("DateIncorrecte")! {{vm.startDateInvalidMessage}}</div>
<div ng-messages-include="error-messages"></div>
ts-valid-date is a custom directive:
angular.module('app')
.directive('tsValidDate', ['$parse', function ($parse) {
return {
require: 'ngModel',
link: function (scope, elem, attrs, ctrl) {
scope.$watch(function () {
return $parse(attrs.min)(scope) <= ctrl.$modelValue && $parse(attrs.max)(scope) >= ctrl.$modelValue;
}, function (currentValue) {
ctrl.$setValidity('invalidDate', currentValue);
});
}
};
}]);
This gives me the wanted solution, invalid the input and show ng-message with the minDate and maxDate allowed
Here's the javascript part of html:
$scope.dateOptions = {
showButtonBar: false,
startingDay: 1
};
$scope.startMinDate = new Date();
$scope.startMaxDate = new Date(new Date().getFullYear() + 5, new Date().getMonth(), new Date().getDate());
$scope.endMinDate = new Date();
$scope.endMaxDate = new Date(new Date().getFullYear() + 5, new Date().getMonth(), new Date().getDate());
vm.startDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.startMinDate), $filter('date')($scope.startMaxDate));
vm.endDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.endMinDate), $filter('date')($scope.endMaxDate));
$scope.disabledStart = function (date, mode) {
return date <= $scope.startMinDate || date > $scope.startMaxDate;
};
$scope.disabledEnd = function (date, mode) {
return date < $scope.endMinDate || date >= $scope.endMaxDate;
};
$scope.verifyDate = function () {
if ($scope.offre.startDate) {
$scope.endMinDate = $scope.offre.startDate;
vm.startDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.startMinDate), $filter('date')($scope.startMaxDate));
vm.endDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.endMinDate), $filter('date')($scope.endMaxDate));
}
if ($scope.offre.endDate) {
$scope.startMaxDate = $scope.offre.endDate;
vm.startDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.startMinDate), $filter('date')($scope.startMaxDate));
vm.endDateInvalidMessage = abp.utils.formatString($scope.dateInvalidMessage,
$filter('date')($scope.endMinDate), $filter('date')($scope.endMaxDate));
}
};
$scope.$watch('offre.endDate', function () {
$scope.verifyDate();
});
$scope.$watch('offre.startDate', function () {
$scope.verifyDate();
});
$scope.openStart = function ($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.openedStart = true;
};
$scope.openEnd = function ($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.openedEnd = true;
};

It can be connected to this issue.
Try to change min-date to min. and max-date to max.
Also keep in mind this issue. So you will be still able to type in manually date in the input field, though your calender will be disabled.

Date picker validation in angularJS not working

I am trying to implement validations for my date time picker. I have a 'From' date picker and a 'To' datepicker in an Angular partial view. I want the 'From' date picker to display error message if a past date is selected and the 'To' date picker should display error message if the selected date is before the 'From' date. The error messages are supposed to appear on selection of the date.
My HTML is :
<div>
<form id="edit-profile" novalidate name="editReservationForm" autocomplete="off" class="form-horizontal">
<fieldset>
<div class="control-group">
<label class="control-label" for="reservation.reservedFrom">Reserved From<sup>*</sup></label>
<div class="controls input-group date" data-provide="datepicker">
<input type="text" class="span4" style="width:150px" name="reservedFrom" placeholder="Reserved From" ng-model="reservation.reservedFrom"
validator="required" required-error-message="Date is required" valid-method="watch" id="startDate" />
<div class="input-group-addon">
<span class="glyphicon glyphicon-th"></span>
</div>
</div> <!-- /controls -->
</div> <!-- /control-group -->
<div class="control-group">
<label class="control-label" for="reservation.reservedTill">Reserved Till<sup>*</sup></label>
<div class="controls input-group date" data-provide="datepicker">
<input type="text" style="width:150px" class="span4" name="reservedTill" placeholder="Reserved Till" ng-model="reservation.reservedTill"
validator="required" required-error-message="Date is required" valid-method="checkErr" id="endDate" ng-change='checkErr()' />
<div class="input-group-addon">
<span class="glyphicon glyphicon-th"></span>
</div>
<span>{{errMessage}}</span>
</div> <!-- /controls -->
</div> <!-- /control-group -->
</fieldset>
</form>
</div>
Controller :
myApp.controller('editReservationController', ['$scope', '$filter', 'reservationResolved', 'pocResolved', 'accountResolved', 'reservationServices', '$location', '$state',
function ($scope, $filter, reservationResolved, pocResolved, accountResolved, reservationServices, $location, $state) {
$scope.reservation = new Object();
$scope.accounts = accountResolved.data;
$scope.pocs = pocResolved.data;
$scope.reservation.employee = reservationResolved.data;
$scope.updateReservation = function () {
if ($scope.editReservationForm.$valid) {
//TODO: fix it properly
$scope.reservation.reservedTill = '';
$scope.reservation.reservedFrom = '';
$scope.reservation.reservedFrom = $('#startDate').val();
$scope.reservation.reservedTill = $('#endDate').val();
reservationServices.updateReservation($scope.reservation).then(function (result) {
$scope.data = result.data;
if (!result.data.error) {
$state.transitionTo('employeeTalentPool', {
id: $state.params.id
});
}
});
}
};
$scope.cancel = function () {
$location.path("/reservations");
};
$scope.checkErr = function () {
var startDate = new Date($scope.reservation.reservedFrom),
endDate = new date($scope.reservation.reservedTill);
$scope.errMessage = '';
if (startDate < new Date()) {
$scope.errMessage = 'Start Date should be greater than or equal today';
return false;
}
if (new Date(endDate) < new Date()) {
$scope.errMessage = 'End Date should be greater than or equal today';
return false;
}
if (endDate < startDate) {
$scope.errorMsg = "End must be after start";
return false;
}
return true;
};
}]);
I am totally new to Angular and I'm trying to understand it by doing projects. Can anyone have a check and provide a solution?
Thanks in advance...
A different approach without displaying any error message and satisfying selection criteria as mentioned in problem statement
Here is the plunker of working solution bit slightly different from your implementation,I've used bootstrap datepicker for this example which is almost similar to datetimepicker. Hope this will give you an understanding.
In the controller we can control when and what from and to dates should be disabled on their corresponding selection.Using minDate provided by datepicker we can change the min date of To date field to From date's.
By doing this we can eliminate the display of error message and which will also satisfy your selection criteria of From & To dates.
angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function($scope) {
$scope.datePicker = {};
$scope.start = new Date();
$scope.end = new Date();
$scope.datePicker.minStartDate = new Date();
// $scope.datePicker.maxStartDate = $scope.end;
$scope.datePicker.minEndDate = $scope.start;
// $scope.datePicker.maxEndDate = $scope.end; //fixed date same as $scope.maxStartDate init value
// watcher to watch the "From" date and set the min date for 'To' datepicker
$scope.$watch('start', function(v) {
$scope.datePicker.minEndDate = v;
$scope.dateOptions2.minDate = v;
});
$scope.dateOptions1 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
// maxDate: $scope.datePicker.maxStartDate,
minDate: $scope.datePicker.minStartDate,
startingDay: 1
};
$scope.dateOptions2 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
// maxDate: $scope.datePicker.maxEndDate,
minDate: $scope.datePicker.minEndDate,
startingDay: 1
};
// Disable weekend selection
function disabled(data) {
var date = data.date,
mode = data.mode;
return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
}
$scope.open1 = function() {
$scope.popup1.opened = true;
};
$scope.open2 = function() {
$scope.popup2.opened = true;
};
$scope.formats = ['dd.MM.yyyy'];
$scope.format = $scope.formats[0];
$scope.altInputFormats = ['M!/d!/yyyy'];
$scope.popup1 = {
opened: false
};
$scope.popup2 = {
opened: false
};
});
In your HTML you can display like below
<div ng-controller="DatepickerPopupDemoCtrl">
<h5>From Date</h5>
<p class="input-group">
<input type="text"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-model="start"
is-open="popup1.opened"
datepicker-options="dateOptions1"
close-text="Close"
readonly="true" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open1()">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
<hr>
<h5>To Date</h5>
<p class="input-group">
<input type="text"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-model="end"
is-open="popup2.opened"
datepicker-options="dateOptions2"
close-text="Close"
readonly="true"/>
<span class="input-group-btn">

AngularUI: range datepicker don't block dates

Can anybody help?
I wanted in my start-datepicker blocked dates after end-date and blocked dates in end-datepicker before start-date.
I used angularui datepickers.
I tried to do this using this code:
$scope.start = new Date();
$scope.end = new Date($scope.start.getTime() + 7 * 24 * 60 * 60 * 1000);
$scope.minStartDate = 0; //fixed date
$scope.maxStartDate = $scope.end; //init value
$scope.minEndDate = $scope.start; //init value
$scope.maxEndDate = $scope.end; //fixed date same as $scope.maxStartDate init value
$scope.$watch('start', function(v){
$scope.minEndDate = v;
});
$scope.$watch('end', function(v){
$scope.maxStartDate = v;
});
And here's plunker:
http://plnkr.co/edit/tTBcSZE08VYCpitdhCRA?p=preview
I have updated your plunker with the necessary changes, basically you were setting minDate and maxDate incorrectly.You have declared date options but there is no such object in your controller, so I've added two date-options object for the calendars respectively. Here is the working code.
Changes in your JS are as below
$scope.datePicker ={};
$scope.start = new Date();
$scope.end = new Date($scope.start.getTime() + 7 * 24 * 60 * 60 * 1000);
$scope.datePicker.minStartDate = 0; //fixed date
$scope.datePicker.maxStartDate = $scope.end; //init value
$scope.datePicker.minEndDate = $scope.start; //init value
$scope.datePicker.maxEndDate = $scope.end; //fixed date same as $scope.maxStartDate init value
$scope.$watch('start', function(v) {
$scope.datePicker.minEndDate = v;
$scope.dateOptions2.minDate = v; //chabge the same in date options object to reflect in UI
});
$scope.$watch('end', function(v) {
$scope.datePicker.maxStartDate = v;
$scope.dateOptions1.maxDate = v;
});
//create two separate objects for date options where you can set ,in and max date..
$scope.dateOptions1 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
maxDate: $scope.datePicker.maxStartDate,
minDate: $scope.datePicker.minStartDate,
startingDay: 1
};
$scope.dateOptions2 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
maxDate: $scope.datePicker.maxEndDate,
minDate: $scope.datePicker.minEndDate,
startingDay: 1
};
Changes in your HTML as below
<div ng-controller="DatepickerPopupDemoCtrl">
<p class="input-group">
<input type="text"
class="form-control"
uib-datepicker-popup="{{format}}"
ng-model="start"
is-open="popup1.opened"
datepicker-options="dateOptions1"
close-text="Close"

Angularjs factory data or object inaccessible directly inside the controller

I have just created an Angular JS factory (below is the code) which returns data for two datepickers (ui.bootstrap's elements) and bind to my html code, but when I am trying to modify the return $scope object by factory inside the controller its not working, I mean I cannot access the $scope.Date1 or $scope.Date2 objects which are available inside the controller (returned from factory).
var MyApp = angular.module("TestApp", ["ui.bootstrap"]);
angular.module('TestApp').factory('FirstFactory', function() {
return {
TwoDates: function(scope) {
scope.clear = function() {
scope.Date1 = null;
scope.Date2 = null;
};
scope.inlineOptions1 = {
customClass: getDayClass,
minDate: new Date(),
// showWeeks: true
};
scope.inlineOptions2 = {
customClass: getDayClass,
minDate: new Date(),
// showWeeks: true
};
scope.dateOptions1 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
maxDate: new Date(2050, 7, 22),
minDate: new Date(),
startingDay: 1
};
scope.dateOptions2 = {
//dateDisabled: disabled,
formatYear: 'yyyy',
maxDate: new Date(2050, 5, 22),
minDate: new Date(),
//minDate: new Date($scope.changeMin()),
startingDay: 1
};
scope.toggleMin = function() {
scope.inlineOptions1.minDate = scope.inlineOptions1.minDate ? null : new Date();
scope.dateOptions1.minDate = scope.inlineOptions1.minDate;
var min2 = new Date();
scope.$watch('Date1', function() {
min2 = scope.Date1;
scope.dateOptions2.minDate = min2;
if (scope.Date1 > scope.Date2) {
// debugger;
scope.Date2 = scope.Date1;
console.log("Yes It's greater");
}
// console.log(min2);
});
scope.$watch('Date2', function() {
if (scope.Date2 < scope.Date1) {
//debugger;
scope.Date1 = scope.Date2;
console.log("Yes It's lesser");
}
// console.log(max1);
});
};
scope.toggleMin();
scope.open1 = function() {
scope.popup1.opened = true;
};
scope.open2 = function() {
scope.popup2.opened = true;
};
scope.popup1 = {
opened: false
};
scope.popup2 = {
opened: false
};
scope.setDate = function(year, month, day) {
scope.Date1 = new Date(year, month, day);
scope.Date2 = new Date(year, month, day);
};
scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd-MM-yyyy', 'shortDate'];
scope.format = scope.formats[2];
scope.altInputFormats = ['M!/d!/yyyy'];
function getDayClass(data) {
var date = data.date,
mode = data.mode;
if (mode === 'day') {
var dayToCheck = new Date(date).setHours(0, 0, 0, 0);
for (var i = 0; i < scope.events.length; i++) {
var currentDay = new Date(scope.events[i].date).setHours(0, 0, 0, 0);
if (dayToCheck === currentDay) {
return scope.events[i].status;
}
}
}
return '';
}
}
};
});
angular.module('TestApp').controller('StartDate', function($scope, $log, FirstFactory) {
//debugger;
FirstFactory.TwoDates($scope);
//or
console.log($scope.Date1);
});

You constructed your factory return statement very oddly. Instead of this:
angular.module('TestApp').factory('FirstFactory', function() {
return {
TwoDates: function(scope) {
scope.example = function() {
//logic
}
//etc functions
}
}
}
Try it like this instead.
angular.module('TestApp').factory('FirstFactory', function() {
var Date1 = 0;
var Date2 = 0;
TwoDates.example = function(){
//logic on Date1 or Date2
}
//TwoDates.exampleFunction = function(){....
return TwoDates; //Important!
}
Notice that the factory's purpose is to return an object that contains all of your logic and variables.
This way you'll be able to use the Date1 and Date2 variables from within the factory and in any controllers that you use the factory in using factoryInstance.getDate1.
In the end your code (the very basics at least) will look like this
var MyApp = angular.module("TestApp", ["ui.bootstrap"]);
angular.module('TestApp').factory('FirstFactory', function() {
var Date1 = 0;
var Date2 = 0;
TwoDates.incrDate1 = function(){
Date1 += 1;
}
TwoDates.getDate1 = function(){
return Date1;
}
return TwoDates;
}
angular.module('TestApp').controller('StartDate', function($scope, FirstFactory) {
//get *function* that returns variables from Factory
//notice that I don't use FF.getDate1(), but instead pass the function without invoking it
$scope.getDate1 = FirstFactory.getDate1; //<-- no ()
console.log($scope.getDate1); // 0
FirstFactory.incrDate1(); // calls Factory method, uses Date1 variable
console.log($scope.getDate1); // 1
//you can also add other factory functions to your scope so you can use them in the html
$scope.incrDate1 = FirstFactory.incrDate1();
});
Here's another stackoverflow question that might help you out.

Form Validation not working with ui-boostrap

I'm having a bit of trouble getting the form to run it's validation function. I have a plnkr. I Know I'm close... The validation file is loading in without errors. It's just not running the validation part. I built it off of this. What am I missing? Thanks in advance for the help.
my Form:
<form id="phone" class="content-pad span6" novalidate>
<div class="control-group" ng-class="{error:!input-form-Phone.phonenumber.$valid}">
<label for="phonenumber">Enter Area Code and Telephone Number</label>
<div class="form-group controls">
<input type="text" class="form-control" id="inputphonenumber" name="phonenumber" ng-model="phonenumber"
placeholder="Ex: 4155551234" valid-phonenumber/>
<div class="help-inline">
<span ng-show="!!phone.phonenumber.$error.isBlank">Phone Number Required.</span>
<span ng-show="!!phone.phonenumber.$error.invalidChars">Must Contain Number Only</span>
<span ng-show="!!phone.phonenumber.$error.invalidLen">Phone Number Must Contain area Code and Phone Number.</span>
</div>
</div>
</div>
<div class="form-actions" ng-show="formAllGood()">
<div class="span6">
<a ng-href="SA_report_results.html" class="btn btn-primary " type="button">Run Report</a>
</div>
</div>
<div class="span3" >
<input type="button" value="Reset" ng-click="reloadPage()" class="btn btn-danger "/>
</div>
</form>
app,js
var app = angular.module('myApp', ['myApp.formValidation','ui.bootstrap']);
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.formAllGood = function(){
return ($scope.phonenumberGood);
};
});
validation,js
angular.module('myApp.formValidation', [])
.directive('validPhoneNumber', function () {
return {
require: 'ngModel',
link: function (scope, elm, attrs, ctrl) {
ctrl.$parsers.unshift(function (viewValue) {
// Any way to read the results of a "required" angular validator here?
var isBlank = viewValue === '';
var invalidChars = !isBlank && !/^[A-z]+$/.test(viewValue);
var invalidLen = !isBlank && !invalidChars && (viewValue.length < 5 || viewValue.length > 20);
ctrl.$setValidity('isBlank', !isBlank);
ctrl.$setValidity('invalidChars', !invalidChars);
ctrl.$setValidity('invalidLen', !invalidLen);
scope.phonenumberGood = !isBlank && !invalidChars && !invalidLen;
});
}
};
});
You are calling valid-phonenumber which doesn't exist. It is valid-phone-number. This will make your plunker run.
By the way your invalidChars check is wrong.

watch expression new value always equals to old value

i'm using two AngularJS Bootstrap-ui Datepicker directives in a single controller.
The code is very simple, the view :
<div class="row">
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="dd-MM-yyyy" ng-model="startDate" is-open="startDateOpened" min="minDate" max="'2015-06-22'" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button class="btn btn-default" ng-click="open($event, 'startDateOpened')"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="dd-MM-yyyy" ng-model="endDate" is-open="endDateOpened" min="minDate" max="'2015-06-22'" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button class="btn btn-default" ng-click="open($event, 'endDateOpened')"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
</div>
The controller (part of it).
var now = new Date();
var startDate = $scope.startDate = new Date(now.getFullYear(), now.getMonth(), 1); // beginning of month
var endDate = $scope.endDate = now;
$scope.$watchCollection('[startDate, endDate]', function (newVals, oldVals) {
if(!(newVals[0] === oldVals[0] && newVals[1] === oldVals[1])){
console.log('old values', oldVals);
console.log('new values', newVals);
print();
}
});
function print() {
console.log('startDate !', startDate);
console.log('endDate !', endDate);
}
$scope.open = function($event, name) {
$event.preventDefault();
$event.stopPropagation();
$scope[name] = true;
};
I am assigning two models - startDate and endDate. Everything looks like it is working fine, when I choose a date in either of the date pickers $scope.$watchCollection() callback is fired up but oldVals is always eqaul to newVals so the model doesn't really change (even though the change event listener is fired).
What am I doing wrong ? I'm guessing it's a lack of understanding something basic :)
Thanks
EDIT
#Maxim's answer of using deep watch did solve my problem of not going into the if statement. Now my other problem is that print function inside the callback always prints the old values of startDate and endDate
Try $watch with flag true aka deep watch:
$scope.$watch('[startDate, endDate]', function (newVals, oldVals) {
if(!(newVals[0] === oldVals[0] && newVals[1] === oldVals[1])){
console.log('old values', oldVals);
console.log('new values', newVals);
startDate = newVals[0];
endDate = newVals[1];
}
}, true);
