GravityView: redirect a user to a different location after updating an entry

redirect.php

<?php
/**
 * Redirect the visitor to the single entry view after updating the entry
 */ 
function my_gv_redirect_after_update_to_single_entry_view( $form, $entry_id ) {
    ?>
	<script>
		jQuery(document).ready( function() {
			window.location.replace( window.location.href.split('?')[0] );
		});
	</script>
    <?php
}
add_action( 'gravityview/edit_entry/after_update', 'my_gv_redirect_after_update_to_single_entry_view',10, 2  );



/**
 * Redirect the visitor to google.com after updating the entry
 */ 
function my_gv_redirect_after_update_to_external_page( $form, $entry_id ) {
    ?>
	<script>
		jQuery(document).ready( function() {
			window.location.replace("http://www.google.com");
		});
	</script>
    <?php
}
add_action( 'gravityview/edit_entry/after_update', 'my_gv_redirect_after_update_to_external_page',10, 2  );

this looks great. i know it's a bit old. but do you have any suggestions on how to make this work so that it only does this redirect when a certain selection is made in the updating process? I'd like to conditionally set whether this redirection happens, based on a user's selection
