Sponsor_Domain_Validation.js

/*
 * Sponsor_Domain_Validation.js 
 * 
 * Author: Alan Nix
 * Version: 1.0
 * Release Date: 08/29/2018
 * 
 * The Javascript below is meant to validate the email address domain that the Guest enters in the "Person Being Visited" field.
 * The script will check against the "allowed_domains" variable, and de-activate the registration form if the domain is not valid.
 * The user will also receive visual feedback that the domain is invalid.
 *
 * NOTE:  This is ONLY client-side validation, and does not prevent the user from modifying the Javascript in their local browser... but it's better than nothing.
 *
 * Place this code in the "Registration Form" -> "Optional Content 1" portion of the Self-Registered Portal's page customizations.
