Post preview - Passing data with AJAX and Fancybox

Question

I\'m trying to do a post preview, which will appears in a new Fancybox iframe. Since couple of weeks I\'m looking for some help or best practices, but I can\'t find it.

Answer 1

I have tried a more interesting way with fancybox that works,

in the fancybox page

var myvar;
$(document).ready(function(){
    myvar = parent.$("#formvariwant").val();
});
