为什么选择今天以外的日期时不能将时间选择器降级？

Question

My html code like this :

<div class="container">
    <div class="row">
        <div class='col-sm-6'>
            <div class="form-group">
                <input type='text' class="form-control" id='datepicker' data-date-format="DD-MM-YYYY" />
            </div>
        </div>

        <div class='col-sm-6'>
            <div class="form-group">
                <input type='text' class="form-control" id='timepicker' data-date-format="HH:mm" />
            </div>
        </div>
    </div>
</div>
<button id="btnSubmit">
    Submit
</button>

My JavaScript code like this:

$(function () {    
    $('#datepicker').datetimepicker();

    $('#timepicker').datetimepicker({
        minDate: moment().startOf('minute').add(300, 'm'),
    });
});
$("#btnSubmit").click(function() {
    value = document.getElementById('datetimepicker').value;
    console.log(value)
});

Demo like this: https://jsfiddle.net/8jpmkcr5/89/

If I click the timepicker and click the decrement hour icon, it does not work. I know it happens because this code : minDate: moment().startOf('minute').add(300, 'm') . I want the code to work only on this day. Other than today the code does not work

How can I do it?

Answer 1

Your #datepicker and #timepicker are unrelated , they are fully independent , is up to you to relate them. You can dinamically set minDate of #timepicker using minDate function.

You can add a listner for dp.change event and enable or disable the minDate for the #timepicker chceking if the selected day is current day (using momentjs isSame ).

You have to add minDate option also to #datepicker if you want to disable past dates, as you stated in the comments.

Here a working sample:

 $(function () { $('#datepicker').datetimepicker({ minDate: moment().startOf('day') }).on('dp.change', function(e){ if( e.date && e.date.isSame(moment(), 'd') ){ var min = moment().startOf('minute').add(300, 'm'); $('#timepicker').data("DateTimePicker").minDate(min); } else { $('#timepicker').data("DateTimePicker").minDate(false); } }); $('#timepicker').datetimepicker({ minDate: moment().startOf('minute').add(300, 'm'), }); }); $("#btnSubmit").click(function() { value = document.getElementById('datepicker').value; console.log(value) valueTime = document.getElementById('timepicker').value; console.log(valueTime) });

Please note that, as stated before, #datepicker and #timepicker are unrelated, so with the #timepicker you are simply selecting a time, that defaults to current day (no automatic relationship with the selected day using #datepicker ).

Answer 2

If you want to limit the input to today only, why are you trying to set a limit on the time picker? You should be setting the limit on the date picker
