Hi @Deep4
you can use Date field type or variable type to avoid the scripting
otherwise right on change Client script on field and write below code
// Regular expression to validate date format (MM/DD/YYYY)
var dateFormat = /^(0[1-9]|1[0-2])\/(0[1-9]|[12][0-9]|3[01])\/\d{4}$/;
// Check if the date matches the format
if (!dateFormat.test(newValue)) {
// If the date is invalid, display an error message
g_form.showFieldMsg('date', 'Please enter a valid date in MM/DD/YYYY format', 'error');
return;
}
// Split the date into its components
var dateParts = newValue.split('/');
var month = parseInt(dateParts[0], 10);
var day = parseInt(dateParts[1], 10);
var year = parseInt(dateParts[2], 10);
// Check for logical date correctness
if (!isValidDate(month, day, year)) {
g_form.showFieldMsg('date', 'Please enter a valid date', 'error');
return;
}
// Check if the date is in the past
var today = new Date();
today.setHours(0, 0, 0, 0); // Set time to the start of the day
var inputDate = new Date(year, month - 1, day);
if (inputDate < today) {
g_form.showFieldMsg('date', 'The date cannot be in the past', 'error');
} else {
// Remove any error message if the date is valid
g_form.hideFieldMsg('date');
}
function isValidDate(month, day, year) {
// Check for leap year
var isLeapYear = (year % 4 === 0 && year % 100 !== 0) || (year % 400 === 0);
// Days in each month
var daysInMonth = [31, (isLeapYear ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];
// Check if day is valid for the given month
return day > 0 && day <= daysInMonth[month - 1];
}
output
