Redirects to a custom link after submits the subscription form

MailPoet: Redirect After Submit

<script>
(function($){
	$(document).ready(function(){
		$( 'form.widget_wysija' ).submit(function(e){
			e.preventDefault();
			setTimeout(function() {
				var msg = $( '.wysija-msg' );
				if( msg.text() !== '' ){
					window.location.replace( 'http://your_thank_you_page_url' );
				}
			}, 3000);
		});
	});
})(window.jQuery);
</script>

Hi, can you help me?
I'm using two forms to subscribe to the same newslleter list. But each one redirects for a differents pages after submission.
Is it possible in this code specify the two forms? Using the if or something like that?
Thank you!
