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

Some clarifications :

• You should use .find() to find elements by selector (you are trying to find a variable .find(test), which is not a valid format).
• You should use .val() to get the contents of an input field or .val(new_value) to set the contents of an input field
• You should use .html() or .text() to get the contents of any element other than input,

example: having this html code

hola

... and this jQuery code

var temp = $(".test").html();

... temp will return hola.

On the other hand, if you have control over the iframed page and it's under the same domain than the parent page, then you may not need to set any jQuery in the child page.

so, having this html in the child (iframed) page for instance

You could set this jQuery in your parent page to get the contents of any clicked element in your child page :

var _tmpvar; // the var to use through the callbacks
jQuery(document).ready(function ($) {
    $(".fancybox").fancybox({
        type: "iframe",
        afterShow: function () {
            var $iframe = $('.fancybox-iframe');
            $iframe.contents().find(".members_body p").each(function (i) {
                $(this).on("click", function () {
                    _tmpvar = $('.members_body p:eq(' + i + ')', $iframe.contents()).html();
                    $.fancybox.close();
                }); // on click
            }); // each
        },
        afterClose: function () {
            $('#form input[name=username]').val(_tmpvar);
        }
    });
}); // ready

Notice that we declared the var _tmpvar globally so we can use it within different callbacks.
