How to add 10 days to current date using client scripts

[anur]

I have a field "RequestedDate" in a service catalog form. Need to populate it with value equal to current date plus 10 days.

Please suggest implementing this with a client script.

You can do it by setting the default value of the variable. You can check the below blog

Auto-populating and validating date fields

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}

// Get start date from field
var startDateStr = g_form.getValue('u_start_date');
var startDate = new Date(startDateStr);

// Add 5 days
startDate.setDate(startDate.getDate() + 5);

// Format to user's date format or standard YYYY-MM-DD
var yyyy = startDate.getFullYear();
var mm = String(startDate.getMonth() + 1).padStart(2, '0');
var dd = String(startDate.getDate()).padStart(2, '0');

var formattedEndDate = yyyy + '-' + mm + '-' + dd;

// Set the value in 'u_end_date' field
g_form.setValue('u_end_date', formattedEndDate);
}

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue === '') return;

var startDateStr = g_form.getValue('u_start_date');
var endDateStr = g_form.getValue('u_end_date');

if (!startDateStr || !endDateStr) return;

var startDate = new Date(startDateStr);
var endDate = new Date(endDateStr);

var diffTime = endDate - startDate;
var diffDays = diffTime / (1000 * 60 * 60 * 24);

if (diffDays < 0) {
g_form.showFieldMsg('u_end_date', 'End date cannot be before start date.', 'error');
g_form.setValue('u_end_date', '');
} else if (diffDays > 365) {
g_form.showFieldMsg('u_end_date', 'End date cannot be more than 365 days from start date.', 'error');
g_form.setValue('u_end_date', '');
}
}
