Prevent user from selecting date within 30 days of current date

[Valerie24]

I'm trying to create an onChange Catalog Client Script that will display a modal pop up when someone enters a date that is within 30 days from the current date. I've tried using a number of scripts posted on community but they are not working for me. We do not want to use a UI Policy/Action for this. Any help with a script to achieve this would be greatly appreciated!

• Variable = u_correction_begin_date 
• If u_correction_begin_date is within 30 days of current date they should receive a modal pop up indicating "you cannot submit a date within 30 days of today."
• If u_correction_begin_date is 30 days or more, no pop up should appear. 

Thank you in advanced!

Would this work if I had a similar need, but the 2 fields are variables?

Here is what we have

Date leaving variable

Date returning variable

The days between the 2 cannot exceed 30

Is there a way to do that?

To achieve your desired behavior in a ServiceNow Catalog Client Script using the onChange event, here is a script that will trigger a modal pop-up when the entered date is within 30 days of the current date:

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

    // Get the current date and the entered date
    var currentDate = new Date();
    var enteredDate = new Date(newValue);

    // Calculate the difference in time (milliseconds)
    var timeDifference = enteredDate.getTime() - currentDate.getTime();

    // Convert the time difference to days
    var dayDifference = Math.ceil(timeDifference / (1000 * 3600 * 24));

    // Check if the date is within 30 days
    if (dayDifference < 30) {
        // Show the modal pop-up if within 30 days
        g_form.showFieldMsg('u_correction_begin_date', 'You cannot submit a date within 30 days of today.', 'error');
    } else {
        // Clear any previous field messages if applicable
        g_form.clearMessages();
    }
}

Explanation:

• The script listens for changes in the u_correction_begin_date field.
• It calculates the difference between the current date and the entered date.
• If the difference is less than 30 days, a modal pop-up will appear, preventing submission.
