How can I get date object from a bootstrap-datetime-picker plugin?

Question

I am trying to utilize tempusdominus-datetimepicker-3 to create a date-time picker in my html-forms.

However, I need to be able to get the selected date from it. The plugin has an option called date which according to the document should return a moment object or null. Here is what the document say about this option

Returns the component's model current date, a moment object or null if not set

However, I am struggling to access the date option.

Also from the doc

Note All options are accessed via the data attribute e.g. $('#datetimepicker').datetimepicker(OPTION, ARGUMENT)

So I tried the following to access the date option.

from = $('#datetimepicker').datetimepicker('date');
from = $('#datetimepicker').datetimepicker('data', 'date');
from = $('#datetimepicker').datetimepicker('data').date;
from = $('#datetimepicker').datetimepicker(function(e){
    return e.date;
});

But none of the above is returning the object. How can I access the date object?

I would think a nice plugin like this one will have more readable option like getDate(), setDate(date), getFomat() and setFormat(...) etc; or event examples, which should eliminate questions like this one, but unfortunately it does not.

Answer 1

Maybe i am wrong but the way I interpret "Note All options are accessed via the data attribute" it says to access the functions in the following format

$("#YOU_SELECTOR").data('DateTimePicker').FUNCTION();

if you try to console.log($("#YOU_SELECTOR").data('DateTimePicker'));

You will see that it prints all those functions that it says are accessible via data attribute, a few I am printing below

{
    "destroy": function () {
        H(), I(), i.widget.remove(), i.element.removeData("DateTimePicker"), i.component && i.component.removeData("DateTimePicker")
    },
    "show": function (a) {
        if (!l().prop("disabled")) {
            if (i.options.useCurrent && "" === l().val()) {
                if (1 !== i.options.minuteStepping) {
                    var c = b(),
                        d = i.options.minuteStepping;
                    c.minutes(Math.round(c.minutes() / d) * d % 60).seconds(0), i.setValue(c.format(i.format))
                } else i.setValue(b().format(i.format));
                o("", a.type)
            }
            a && "click" === a.type && i.isInput && i.widget.hasClass("picker-open") || (i.widget.hasClass("picker-open") ? (i.widget.hide(), i.widget.removeClass("picker-open")) : (i.widget.show(), i.widget.addClass("picker-open")), i.height = i.component ? i.component.outerHeight() : i.element.outerHeight(), n(), i.element.trigger({
                type: "dp.show",
                date: b(i.date)
            }), G(), a && B(a))
        }
    },
    "disable": function () {
        var a = l();
        a.prop("disabled") || (a.prop("disabled", !0), H())
    },
    "enable": function () {
        var a = l();
        a.prop("disabled") && (a.prop("disabled", !1), F())
    },
    "hide": function () {
        var a, c, d = i.widget.find(".collapse");
        for (a = 0; a < d.length; a++)
            if (c = d.eq(a).data("collapse"), c && c.transitioning) return;
        i.widget.hide(), i.widget.removeClass("picker-open"), i.viewMode = i.startViewMode, E(), i.element.trigger({
            type: "dp.hide",
            date: b(i.date)
        }), I()
    },
    "setValue": function (a) {
        b.locale(i.options.language), a ? i.unset = !1 : (i.unset = !0, K()), a = b.isMoment(a) ? a.locale(i.options.language) : a instanceof Date ? b(a) : b(a, i.format, i.options.useStrict), a.isValid() ? (i.date = a, K(), i.viewDate = b({
            y: i.date.year(),
            M: i.date.month()
        }), t(), x()) : p(a)
    },
    "getDate": function () {
        return i.unset ? null : b(i.date)
    },
    "setDate": function (a) {
        var c = b(i.date);
        i.setValue(a ? a : null), o(c, "function")
    },
    "setDisabledDates": function (a) {
        i.options.disabledDates = O(a), i.viewDate && q()
    },
    "setEnabledDates": function (a) {
        i.options.enabledDates = O(a), i.viewDate && q()
    },
    "setMaxDate": function (a) {
        void 0 !== a && (i.options.maxDate = b.isMoment(a) || a instanceof Date ? b(a) : b(a, i.format, i.options.useStrict), i.viewDate && q())
    },
    "setMinDate": function (a) {
        void 0 !== a && (i.options.minDate = b.isMoment(a) || a instanceof Date ? b(a) : b(a, i.format, i.options.useStrict), i.viewDate && q())
    }
    .............. and more,

see below calling getDate() in the demo via a click of a link. you can check after changing the date to verify.

$(document).ready(function() {
  var picker = $('#datetimepicker7').datetimepicker();

  //console.log(picker.datetimepicker('data-view-date'));
  //console.log($('#datetimepicker7').datetimepicker('data-show'));

  $("#tog").on('click', function() {
    //console.log($('#datetimepicker7').data('DateTimePicker'));
    console.log($('#datetimepicker7').data('DateTimePicker').getDate());
  })

});

Answer 2

In case anybody was experiencing the same trouble as me (using bootstrap v4 https://tempusdominus.github.io/bootstrap-4/), and wanting the date at the time the picker is closed, here is the code:

$(function () {
    $('#datetimepicker').datetimepicker();
    $('#datetimepicker').on("datetimepicker.hide", function (e) {
        console.log(moment(e.date).format('YYYY-MM-DD HH:mm'));
    });
});

Note that in this case, datetimepicker comes before hide, which is different to change coming before datetimepicker. Using hide.datetimepicker will not work.

Here is the correct code to access events :

$(function() {
   $('#datetimepicker').datetimepicker();
   $('#datetimepicker').on("change.datetimepicker", function (e) {
      console.log(e.date);
   });
 });

You can get date using this too :

var date = $('#datetimepicker').datetimepicker('viewDate')
