JQuery iframe modal close on form submit

I have a jQuery Modal dialog with iframe in it, iframe includes a form. When the user submits the form, I would like to close the modal dialog.

How can i do this?

jquery modal script on index.php:

<script type="text/javascript">
function showRegDialog(url) {
    $(function() {
            var $this = $(this);
            var horizontalPadding = 30;
            var verticalPadding = 30;
            $('<iframe id="externalSite" scrolling="no" frameborder="0" class="externalSite" src="' + url + '" />').dialog({
                title: ($this.attr('title')) ? $this.attr('title') : 'Choose your location',
                autoOpen: true,
                width: 700,
                height: 700,
                modal: true,
                resizable: true,
                autoResize: true,
                overlay: {
                    opacity: 0.5,
                    background: "black"
                }

            }).width(700 - horizontalPadding).height(700 - verticalPadding);            

    });
}
</script>

link to index.php to call showRegDialog modal:

<a href="javascript:showRegDialog('/register.php');">Register now</a>

This is the contents of register.php

<html>
<body>
<form action="" method="POST">
<input type="text">
<input type="submit">
</form>
</body>
</html>

Call the javascript function in the parent window as follows:

parent.yourJsFunction();

put it in "onsubmit" in your form.

You may be looking for close

Give your form an identifier.

$("#formID").submit(function(){
    parent.closeModal();
});

// function for closing modal window (in parent page)
function closeModal() {
    $("#externalSite").dialog("close");
}
