I am using bootstrap date-picker in my angular application. However when I select a date from that date-picker underlying ng-model that I have bind gets updated I want that ng-model in one date format 'MM/dd/yyyy'. but it every times makes date like this
"2009-02-03T18:30:00.000Z"
instead of
02/04/2009
I have created a plunkr for the same plunkr link
My Html and controller code is like below
<!doctype html>
<html ng-app="plunker">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.2.10/angular.js"></script>
<script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.11.0.js"></script>

</head>
<body>
<div ng-controller="DatepickerDemoCtrl">
<pre>Selected date is: <em>{{dt | date:'MM/dd/yyyy' }}</em></pre>
<p>above filter will just update above UI but I want to update actual ng-modle</p>

</div>
</div>-->
<hr />
{{dt}}
</div>
</body>
</html>
Angular controller
angular.module('plunker', ['ui.bootstrap']);
var DatepickerDemoCtrl = function ($scope) {
$scope.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
$scope.dateOptions = {
formatYear: 'yy',
startingDay: 1
};
$scope.format = 'dd-MMMM-yyyy';
};
Thanks in advance for review my question.
UPDATE
I am calling below method for posting my data and VAR is array of size 900 which contains date-picker variables.
public SaveCurrentData(formToSave: tsmodels.ResponseTransferCalculationModelTS) {
var query = this.EntityQuery.from('SaveFormData').withParameters({
$method: 'POST',
$encoding: 'JSON',
$data: {
VAR: formToSave.VAR,
X: formToSave.X,
CurrentForm: formToSave.currentForm,
}
});
var deferred = this.q.defer();
this.manager.executeQuery(query).then((response) => {
deferred.resolve(response);
}, (error) => {
deferred.reject(error);
});
return deferred.promise;
}
Although similar answers have been posted I'd like to contribute what seemed to be the easiest and cleanest fix to me. Assuming you are using the AngularUI datepicker and your initial value for the ng-Model does not get formatted simply adding the following directive to your project will fix the issue:
angular.module('yourAppName')
.directive('datepickerPopup', function (){
return {
restrict: 'EAC',
require: 'ngModel',
link: function(scope, element, attr, controller) {
//remove the default formatter from the input directive to prevent conflict
controller.$formatters.shift();
}
}
});
I found this solution in the Github AngularUI issues and therefore all credit goes to the people over there.
You can make use of $parsers as shown below,this solved it for me.
window.module.directive('myDate', function(dateFilter) {
return {
restrict: 'EAC',
require: '?ngModel',
link: function(scope, element, attrs, ngModel) {
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue,'yyyy-MM-dd');
});
}
};
});
HTML:
<p class="input-group datepicker" >
<input
type="text"
class="form-control"
name="name"
datepicker-popup="yyyy-MM-dd"
date-type="string"
show-weeks="false"
ng-model="data[$parent.editable.name]"
is-open="$parent.opened"
min-date="minDate"
close-text="Close"
ng-required="{{editable.mandatory}}"
show-button-bar="false"
close-on-date-selection="false"
my-date />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="openDatePicker($event)">
<i class="glyphicon glyphicon-calendar"></i>
</button>
</span>
</p>
I ran into the same problem and after a couple of hours of logging and investigating, I fixed it.
It turned out that for the first time the value is set in a date picker, $viewValue is a string so the dateFilter displays it as is. All I did is parse it into a Date object.
Search for that block in ui-bootstrap-tpls file
ngModel.$render = function() {
var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
element.val(date);
updateCalendar();
};
and replace it by:
ngModel.$render = function() {
ngModel.$viewValue = new Date(ngModel.$viewValue);
var date = ngModel.$viewValue ? dateFilter(ngModel.$viewValue, dateFormat) : '';
element.val(date);
updateCalendar();
};
Hopefully this will help :)
The format specified through datepicker-popup is just the format for the displayed date. The underlying ngModel is a Date object. Trying to display it will show it as it's default, standard-compliant rapresentation.
You can show it as you want by using the date filter in the view, or, if you need it to be parsed in the controller, you can inject $filter in your controller and call it as $filter('date')(date, format). See also the date filter docs.
You may use formatters after picking value inside your datepicker directive. For example
angular.module('foo').directive('bar', function() {
return {
require: '?ngModel',
link: function(scope, elem, attrs, ctrl) {
if (!ctrl) return;
ctrl.$formatters.push(function(value) {
if (value) {
// format and return date here
}
return undefined;
});
}
};
});

With so many answers already written, Here's my take.
With Angular 1.5.6 & ui-bootstrap 1.3.3 , just add this on the model & you are done.
ng-model-options="{timezone: 'UTC'}"
Note: Use this only if you are concerned about the date being 1 day behind & not bothered with extra time of T00:00:00.000Z
Updated Plunkr Here :
All proposed solutions didn't work for me but the closest one was from @Rishii.
I'm using AngularJS 1.4.4 and UI Bootstrap 0.13.3.
.directive('jsr310Compatible', ['dateFilter', 'dateParser', function(dateFilter, dateParser) {
return {
restrict: 'EAC',
require: 'ngModel',
priority: 1,
link: function(scope, element, attrs, ngModel) {
var dateFormat = 'yyyy-MM-dd';
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue, dateFormat);
});
ngModel.$validators.date = function (modelValue, viewValue) {
var value = modelValue || viewValue;
if (!attrs.ngRequired && !value) {
return true;
}
if (angular.isNumber(value)) {
value = new Date(value);
}
if (!value) {
return true;
}
else if (angular.isDate(value) && !isNaN(value)) {
return true;
}
else if (angular.isString(value)) {
var date = dateParser.parse(value, dateFormat);
return !isNaN(date);
}
else {
return false;
}
};
}
};
}])
I can fix this by adding below code in my JSP file. Now both model and UI values are same.
<div ng-show="false">
{{dt = (dt | date:'dd-MMMM-yyyy') }}
</div>
Steps to change the default date format of ng-model
For different date formats check the jqueryui datepicker date format values here for example I have used dd/mm/yy
Create angularjs directive
angular.module('app', ['ui.bootstrap']).directive('dt', function () {
return {
restrict: 'EAC',
require: 'ngModel',
link: function (scope, element, attr, ngModel) {
ngModel.$parsers.push(function (viewValue) {
return dateFilter(viewValue, 'dd/mm/yy');
});
}
}
});
Write dateFilter function
function dateFilter(val,format) {
return $.datepicker.formatDate(format,val);
}
In html page write the ng-modal attribute
<input type="text" class="form-control" date-type="string" uib-datepicker-popup="{{format}}" ng-model="src.pTO_DATE" is-open="popup2.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" show-button-bar="false" show-weeks="false" dt />
Defining a new directive to work around a bug is not really ideal.
Because the datepicker displays later dates correctly, one simple workaround could be just setting the model variable to null first, and then to the current date after a while:
$scope.dt = null;
$timeout( function(){
$scope.dt = new Date();
},100);
The datepicker (and datepicker-popup) directive requires that the ng-model be a Date object. This is documented here.
If you want ng-model to be a string in specific format, you should create a wrapper directive. Here is an example (Plunker):
(function () {
'use strict';
angular
.module('myExample', ['ngAnimate', 'ngSanitize', 'ui.bootstrap'])
.controller('MyController', MyController)
.directive('myDatepicker', myDatepickerDirective);
MyController.$inject = ['$scope'];
function MyController ($scope) {
$scope.dateFormat = 'dd MMMM yyyy';
$scope.myDate = '30 Jun 2017';
}
myDatepickerDirective.$inject = ['uibDateParser', '$filter'];
function myDatepickerDirective (uibDateParser, $filter) {
return {
restrict: 'E',
scope: {
name: '@',
dateFormat: '@',
ngModel: '='
},
required: 'ngModel',
link: function (scope) {
var isString = angular.isString(scope.ngModel) && scope.dateFormat;
if (isString) {
scope.internalModel = uibDateParser.parse(scope.ngModel, scope.dateFormat);
} else {
scope.internalModel = scope.ngModel;
}
scope.open = function (event) {
event.preventDefault();
event.stopPropagation();
scope.isOpen = true;
};
scope.change = function () {
if (isString) {
scope.ngModel = $filter('date')(scope.internalModel, scope.dateFormat);
} else {
scope.ngModel = scope.internalModel;
}
};
},
template: [
'<div class="input-group">',
'<input type="text" readonly="true" style="background:#fff" name="{{name}}" class="form-control" uib-datepicker-popup="{{dateFormat}}" ng-model="internalModel" is-open="isOpen" ng-click="open($event)" ng-change="change()">',
'<span class="input-group-btn">',
'<button class="btn btn-default" ng-click="open($event)"> <i class="glyphicon glyphicon-calendar"></i> </button>',
'</span>',
'</div>'
].join('')
}
}
})();<!DOCTYPE html>

</html>After checking the above answers, I came up with this and it worked perfectly without having to add an extra attribute to your markup
angular.module('app').directive('datepickerPopup', function(dateFilter) {
return {
restrict: 'EAC',
require: 'ngModel',
link: function(scope, element, attr, ngModel) {
ngModel.$parsers.push(function(viewValue) {
return dateFilter(viewValue, 'yyyy-MM-dd');
});
}
}
});
Finally I got work around to the above problem. angular-strap has exactly the same feature that I am expecting. Just by applying date-format="MM/dd/yyyy" date-type="string" I got my expected behavior of updating ng-model in given format.
<div class="bs-example" style="padding-bottom: 24px;" append-source>
<form name="datepickerForm" class="form-inline" role="form">
<!-- Basic example -->
<div class="form-group" ng-class="{'has-error': datepickerForm.date.$invalid}">
<label class="control-label"><i class="fa fa-calendar"></i> Date <small>(as date)</small></label>
<input type="text" autoclose="true" class="form-control" ng-model="selectedDate" name="date" date-format="MM/dd/yyyy" date-type="string" bs-datepicker>
</div>
<hr>
{{selectedDate}}
</form>
</div>
