Dates only with Angular-UI Bootstrap datepicker

gistfile1.js

    app.directive('datepickerLocaldate', ['$parse', function ($parse) {
        var directive = {
            restrict: 'A',
            require: ['ngModel'],
            link: link
        };
        return directive;

        function link(scope, element, attr, ctrls) {
            var ngModelController = ctrls[0];

            // called with a JavaScript Date object when picked from the datepicker
            ngModelController.$parsers.push(function (viewValue) {
                // undo the timezone adjustment we did during the formatting
                viewValue.setMinutes(viewValue.getMinutes() - viewValue.getTimezoneOffset());
                // we just want a local date in ISO format
                return viewValue.toISOString().substring(0, 10);
            });

            // called with a 'yyyy-mm-dd' string to format
            ngModelController.$formatters.push(function (modelValue) {
                if (!modelValue) {
                    return undefined;
                }
                // date constructor will apply timezone deviations from UTC (i.e. if locale is behind UTC 'dt' will be one day behind)
                var dt = new Date(modelValue);
                // 'undo' the timezone offset again (so we end up on the original date again)
                dt.setMinutes(dt.getMinutes() + dt.getTimezoneOffset());
                return dt;
            });
        }
    }]);

Thank you so much!

Thanks very helpful!!

Thanks very helpful!!

Yessss. Thanks!

Yes! yes! yes! Wonderful man! thank you for sharing!

This is awesome! Thanks a lot.

This is good
But in my case this directive worked in While posting
when i retrive and again without edit post then its not removing timezone

This is wonderful. It's solved my problem. Thanks

How look it in html ?

This COULD save me tons of time. Only thing is, I included the directive in my project and called the attribute on my input, but still getting date modeled as "Sat Jan 01 2000 00:00:00 GMT-0600 (Central Standard Time)" to my scope variable. Am I missing something? I'm using the UI-Bootstrap date picker. Does this directive remove the timestamp or does it just add the time stamp from the location where the user is entering it?

It removes the timezone offset from the entered time.

For those having problems with the returned date as undefined, change the ngModelController.$parsers part:

ngModelController.$parsers.push(function (viewValue) {
    // undo the timezone adjustment we did during the formatting
    viewValue.setMinutes(viewValue.getMinutes() - viewValue.getTimezoneOffset());
    // we just want a local date in ISO format
    var dateString = viewValue.toISOString().substring(0, 10);
    var dateParts = dateString.split("-");
    var newDate = new Date( dateParts[0], parseInt( dateParts[1] )-1, dateParts[2], 0, 0, 0 );
    return newDate;
});

The above solutions only work for timezones West of the UTC Timezone. Here's a fix that also works for timezones East of UTC so that dates don't appear one day behind:

 app.directive('datepickerLocaldate', ['$parse', function ($parse) {
    var directive = {
        restrict: 'A',
        require: ['ngModel'],
        link: link
    };
    return directive;

    function link(scope, element, attr, ctrls) {
        var ngModelController = ctrls[0];

        // called once user picks a date from datepicker with a JavaScript Date object
        ngModelController.$parsers.push(function (viewValue) {
            // undo the timezone adjustment we did during the formatting
            viewValue.setMinutes(viewValue.getMinutes() - viewValue.getTimezoneOffset());

            // get a local date in ISO format
            var dateString = viewValue.toISOString().substring(0, 10);
            var dateParts = dateString.split("-");
            var newDate = new Date( dateParts[0], parseInt( dateParts[1] )-1, dateParts[2], 0, 0, 0 );

            if (viewValue.getTimezoneOffset() < 0) {
                //case for Timezones East of UTC (floored to account for Indian Standard Time Zone on 30 minute delineations)
                newDate.setHours(newDate.getHours() - Math.floor(newDate.getTimezoneOffset()/60));
            } else {
                //case for Timezones West of UTC
                return newDate;
            }

            return newDate;
        });

        // called once user saves changes on a Title and passes the Date we had picked in the datepicker
        ngModelController.$formatters.push(function (modelValue) {
            if (!modelValue) {
                return undefined;
            }
            // date constructor will apply timezone deviations from UTC (i.e. if locale is West of UTC 'dt' will be one day behind)
            var dt = new Date(modelValue);

            // 'undo' the timezone offset again (so we end up on the original date again)
            if (dt.getTimezoneOffset() < 0) {
                //case for Timezones East of UTC
                dt.setMinutes(dt.getMinutes() - dt.getTimezoneOffset());
            } else {
                //case for Timezones West of UTC
                dt.setMinutes(dt.getMinutes() + dt.getTimezoneOffset());
            }

            return dt;
        });
