Acrobat Forms: Don't Allow Prior Year Date Entries

This script will not work in Acrobat Reader.

Please note that you have defined a hard stop. On January first, they can't enter data from the prior year. Seems to be a bit to hard...

As the custom Validation script of the field enter the following (adjust the date pattern as needed):

if (event.value) {
	var d = util.scand("mm/dd/yyyy", event.value);
	if (d.getFullYear()<new Date().getFullYear()) {
		app.alert("You may not enter a date from previous years.",1);
		event.rc = false;
	}
}
