Add custom OnClick event to submit button (popup)

Hi, I’m trying to add a custom onclick event to one of my send button of a form.

I added this to my functions.php:

function trigger_func_on_custom_button(){
?>
<script>
    (function($){
        $(window).load(function() {
    	   $('.OptIn_Form input[type="submit"]').on('click', function() {
                if (!$('.OptIn_Form p').hasClass('error')) {
                    ga('send’, 'event', 'OptIn', 'Eingetragen', 'MH_Seite');
                }
                e.preventDefault();
                location.href='http://#ulp-9udMtdl3BptjK3VR';
            });
        });
    })(jQuery);
</script>
<?php
}
add_action('wp_footer', 'trigger_func_on_custom_button');

My form got the custom class OptIn_Form.

But when I click the button, nothing happens. I expect to open a popup (“Layered Popups”) after submitting the form.

Do I have to modify this code?

e.preventDefault();
location.href='http://#ulp-9udMtdl3BptjK3VR';

Thanks for help,
Enrico
