pass value/variable from fancybox iframe to parent

Question

I\'am trying to pass a variable/ value from the fancybox iframe to the parent window without success.

Fancybox is launched from a link with

   class         


        

Answer 1

When the fancybox is closed the iframe is removed from the document. So you must use beforeClose event instead of afterClose

$(document).ready(function() {
    $('a.fancybox').fancybox({
        openEffect:'fade',
        openSpeed:500,
        beforeClose: function() {
            // working
            var $iframe = $('.fancybox-iframe');
            alert($('input', $iframe.contents()).val());
        },
        afterClose: function() {
            // not working
            var $iframe = $('.fancybox-iframe');
            alert($('input', $iframe.contents()).val());
        }
    });
});

EDIT:

I edited your jsfiddle (http://jsfiddle.net/NXY7Y/9/). Update is in this link http://jsfiddle.net/NXY7Y/13/

Main page javscript:

$(document).ready(function() {
    $('a.fancybox').fancybox({
        openEffect:'fade',
        openSpeed:500//,
        //beforeClose: function() {
        //    // working
        //    var $iframe = $('.fancybox-iframe');
        //    alert($('input', $iframe.contents()).val());
        //},
        //afterClose: function() {
        //    // not working
        //    var $iframe = $('.fancybox-iframe');
        //    alert($('input', $iframe.contents()).val());
        //}
    });
});

function setSelectedUser(userText) {
    $('#username').val(userText);
}

No need to use afterClose or beforeClose events. Just access the parent function setSelectedUser from the iframe on link click event like this:

$(document).ready(function() {
    $('a.insert_single').click(function() {
        parent.setSelectedUser($(this).text());
        parent.$.fancybox.close();
    });
});
