How to block the possibility of choosing current day while after 9.00 A.M

0

Hi Igor,
the first condition looks OK.
But in the second one you have to compare the date with TODAY (I assume you have date and time in the "Dzień" field).

I haven't found a function in WEBCON that returns only the date from the datetime field. But you can make a workaround (screenshots)

Hello!

Both resolutions work just fine, thank you very very much!

Best Regards,

Igor

This code checks if the selected date is today and if the current time is after 9:00 A.M., blocking form submission if both conditions are true. Otherwise, it allows the form to be submitted:

function validateForm() {
var selectedDay = document.getElementById('dayField').value;
var today = new Date();
var selectedDate = new Date(selectedDay);

if (selectedDate.toDateString() === today.toDateString()) {
var currentTime = today.getHours();
if (currentTime >= 9) {
alert("You cannot select today after 9:00 A.M.");
return false;
}
}
return true;
}

// Attach this function to your form's onsubmit event
document.getElementById('yourFormId').onsubmit = validateForm;
