You can do this from inside the modal:

document.getElementsByTagName('form')[0].addEventListener(function(e) {
    e.preventDefault();
    //send the form data
    var req = new XMLHttpRequest();
    req.send(new FormData(this));
    //or return some input field value
    returnValue = document.getElementsByTagName('input')[0].value;
    parent.document.getElementsByTagName('dialog')[0].close();
});
