Connecting the input[date] and Moment.js in AngularJS

Question

Connecting the input[date] and Moment.js in AngularJS

For the purpose of formulating a question, I have prepared a simplified example:

...
<input type="date" ng-model="selectedMoment" />
...
<script>
 angular.module('dateInputExample', [])
     .controller('DateController', ['$scope', function($scope) {
       $scope.selectedMoment = moment();
        //...more code...
     }]);
</script>

In essence, what I need is for the binding between the model (using moment.js's date) and the view (input[date] field) to function correctly - the date input should update when the model updates, and vice versa. If you try the above example, you will encounter an error stating that the model is not of the Date type.

This leads me to reach out to experienced AngularJs developers for guidance on how to properly implement this binding.

I would greatly appreciate any advice offered by those who are knowledgeable in this area.

Answer №1

Develop a custom directive that can handle date conversion from moment to formatted date, and vice versa.

Here is a basic example which can be further enhanced with error handling:

myApp.directive('dateConverter', function () {
    return {
        link: function(scope, elem, attrs, ctrl) {
            ctrl.$parsers.push(function(viewValue) {
                return moment(viewValue);
            });
            ctrl.$formatters.push(function(modelValue) {
                return modelValue.format('MM/DD/YYYY');
            });
        },
        require: 'ngModel'
    }
});

If you want to customize a filter, here's an example:

myApp.filter('customize', function() {
    return function(input) {
        // Customize the input here
        return customizedOutput;
    };
});

You can also pass arguments to the filter to perform different customizations. Check out the Angular filters documentation for more ideas on how to tailor filters to your specific requirements.

I tried all the suggestions but none of them worked for me. I faced the same issue and eventually resolved it by:

...
<input type="date" ng-model="selectedMoment" />
...
<script>
 angular.module('dateInputExample', [])
     .controller('DateController', ['$scope', function($scope) {
       $scope.selectedMoment = moment().toDate();
       //...more code...
       var momentDate = moment($scope.selectedMoment);
       //...more code...
     }]);
</script>

<input type="date" />

It is necessary to provide a string in a specific format or use the JavaScript Date() object. http://www.w3schools.com/html/html_form_input_types.asp

You cannot simply use the moment.js object in this case.

If you want the result to be a string, utilize an input with type="date". For moment.js functionality and formatting, you will need to create your own custom directive or filter.

After submission, the original format of the date is transformed into a new format.

HTML

<input type="date" ng-model="input.NewEventDate" >  <button type="button" class="btn btn-success" ng-click="add()">submit</button>

JavaScript

$scope.add = function(){
$scope.input.NewEventDate = moment($scope.input.NewEventDate).format("DD-MM-YYYY");
}
