    How do I center the popup form window on the screen?

    Asked by armadill on July 07, 2015 at 02:40 PM
    Is there a code I can add to that so that it always opens in the middle of the screen, like the lightbox?
    Thank you.

    You may try using the following modified code from the source here to embed on your webpage that opens the pop-up in the center of the page.

    <script language="javascript" type="text/javascript">

            function OpenPopupCenter(pageURL, title, w, h) {

                var left = (screen.width - w) / 2;

                var top = (screen.height - h) / 4;

                var targetWin = window.open(pageURL, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);



        <a target="_blank" href="javascript:void(0)" onclick="OpenPopupCenter('http://form.jotformpro.com/form/23167354874663', 'Suscripción al Newsletter', 700, 500);">Suscripción al Newsletter</a>


    Hope this information helps!
