I can validate the format of this dates using moment library:
2022-03-26T14:15:51 ("YYYY-MM-DDTHH:mm:ss")
2022-03-26 ("YYYY-MM-DD")
But having problem with following :
2022-03-26T14:15:51.667778+03:00 ("YYYY-MM-DDTHH:mm:ss.SSSZ") - this format not solving the problem.
Is there any solution? Maybe using regex will solve?
You could try the format YYYY-MM-DDTHH:mm:ss.SSSSSSZ, I'd also suggest using strict mode when parsing dates. This format will allow a variable amount of digits after the decimal point but will refuse to parse a date with no fractional seconds:
function validateDate(input, format) {
const dt = moment(input, format, true);
return dt.isValid();
}
const testInputs = [
'2022-03-26T14:15:51.667778+03:00',
'2022-03-26T14:15:51.667+03:00',
'2022-03-26T14:15:51+03:00',
'2022-03-26T14:15:51',
'FOO'
]
const format = 'YYYY-MM-DDTHH:mm:ss.SSSSSSZ';
console.log('Input'.padEnd(36), 'Valid');
testInputs.forEach(input => console.log(input.padEnd(36), validateDate(input, format))).as-console-wrapper { max-height: 100% !important; }<script src="https://momentjs.com/downloads/moment.js"></script>
