JQuery - Loading Form Submission In DIV Of Parent Page (?)

I have the following code, which works perfectly ... so far. But I want to next have a form load ... read below this code for an explanation. Main Page:

HTML:

<form action="report_output.php" class="load-external" method="get" id="graphIt" data-target="#right_section">

JS:

$('body').on('submit', 'form.load-external', function(e) {
    e.preventDefault();
    var target = $($(this).data('target'));
    $.ajax({
        url: $(this).attr('action'),
        type: $(this).attr('method'),
        data: $(this).serialize(),
        dataType: 'html',
        success: function(response) {
            target.html(response);
        }
    });
});
