Tempus Dominus Datetime Picker How to set value?

Question

Using v6 from tempusdominus datepicker

Reference: https://getdatepicker.com/6/functions.html

I have tried many function function trying to set a value to the datetime picker but nothing is working,, below my tries:

var DateTimeVal = moment('05/07/2022 00:00').format('MM/DD/YYYY HH:mm');

$('#DateTime').data("DateTimePicker").date(DateTimeVal);

The above sample was working in previous version (4) but in V6 it's giving error:

Cannot read properties of undefined (reading 'date')

2nd try:

Based on the SetVal Function mentioned in the documentation https://getdatepicker.com/6/functions.html

var DateTimeVal = moment('05/07/2022 00:00').format('MM/DD/YYYY HH:mm');

const picker = new tempusDominus.TempusDominus(document.getElementById('DateTime'));

picker.setValue(DateTimeVal);

It's giving error:

picker.setValue is not a function

Would you please assist ? as the mentioned samples not clear in their official website...

Answer 1

Please note that the setValue docs states:

setValue(value: DateTime, index?: number)

Sets the select date index (or the first, if not provided) to the provided DateTime object.

so the parameter that you need to pass to setValue should be a DateTime while in your sample you are using a string.

You can get a DateTime object from a JavaScript Date using DateTime.convert function.

Moreover, you can't access to setValue and other functions directly from picker, but you have to use picker.dates instead.

Working example:

const picker = new tempusDominus.TempusDominus(document.getElementById('datetimepicker1'));

var DateTimeVal = moment('02/02/2022 00:00', 'MM/DD/YYYY HH:mm').toDate();

picker.dates.setValue(tempusDominus.DateTime.convert(DateTimeVal));

Please note that you should specify format when parsing non ISO 8601 string in moment.js (see String + Format) and you can simply get a native JavaScript Date from a moment object using toDate().

Answer 2

Just use this code .. simple for you to set the default datetime, In this case it is the current datetime ..cheers

const picker = new tempusDominus.TempusDominus(document.getElementById('datetimepicker1'));
picker.dates.formatInput = date => moment(date).format('YYYY-MM-DD HH:mm')
picker.dates.setValue();
