Change format of md-datepicker in Angular Material with momentjs

Question

Angular material introduced a new date picker component found here.

I want the date returned by this component to be in the format yyy-mm-dd but I am not sure how is this done. By searching I found that $mdDateLocaleProvider can be used, but I could not find an example of using it.

Can someone show me a working example of formatting the date returned by md-datepicker?

Answer 1

There is a documentation for $mdDateLocaleProvider in the Angular Material docs.

angular.module('app').config(function($mdDateLocaleProvider) {
    $mdDateLocaleProvider.formatDate = function(date) {
       return moment(date).format('YYYY-MM-DD');
    };
});

If you don't use moment.js, substitute the code inside formatDate for whatever you wish to use to format the date.

Here is a CodePen example based on the samples from Angular Material docs.

To also address the problem pointed out by kazuar:

Unfortunately it doesn't work if the date is typed from the keyboard

you should define the parseDate method as well. From the docs:

$mdDateLocaleProvider.parseDate = function(dateString) {
    var m = moment(dateString, 'L', true);
    return m.isValid() ? m.toDate() : new Date(NaN);
};

For a full example, I have in my app (using moment):

$mdDateLocaleProvider.formatDate = function(date) {
    return moment(date).format('DD/MM/YYYY');
};

$mdDateLocaleProvider.parseDate = function(dateString) {
    var m = moment(dateString, 'DD/MM/YYYY', true);
    return m.isValid() ? m.toDate() : new Date(NaN);
};
