title: get a form field value from fancybox iframe and return it to beforeClose function
body: <p>I am using jquery fancybox 2 to load an iframe form.
  The form submits and writes the data to the database then closes the fancybox.
  So that part of its all good.
  However i want to retrieve a hidden field value from the iframe form.
  This value will then hide the corresponding id on the parent page.
  I try to get the hidden field value using the beforeClose option.
  However i cannot get the hidden field value.</p>
  
  <p>The hidden field has an pageload.
  fancybox code:</p>
  
  <pre><code>$(".various").fancybox({
        maxWidth : 800,
        maxHeight   : 700,
        fitToView   : false,
        width    : '70%',
        height      : '90%',
        autoSize : false,
        closeClick  : false,
        openEffect  : 'fade',
        beforeClose : function(){
          var pageload = $('#pageload').val();            
          console.log('var = ' + pageload);
        },
        afterClose : function(){
          if(pageload != 0){
              $('#'+pageload).slideUp('slow');
          } else {
              window.location.reload(true);
          }
        }
      });
  </code></pre>
  
  <p>and the fancybox is triggered by :</p>
  
  <pre><code>&lt;a href="editcategory.php&amp;pageload=&lt;?php echo $sub_id; ?&gt;" class='various' data-fancybox-type='iframe'&gt;LINK&lt;/a&gt;
  </code></pre>
  
  <p>When the iframe popsup there is :</p>
  
  <pre><code>&lt;input type="hidden" value="&lt;?php echo $_GET['pageload']; ?&gt;" id="pageload" name="pageload" /&gt;
  </code></pre>
  
  <p>And all i need to do is return the pageload value back to the afterClose function.
  I have tried using the afterLoad function to get value, the beforeClose function but none of them seem t give me an answer apart from null.
  This will then 'slideup' that id and then clear it in the index page.</p>
  
  <p>If the value = 0 it will do a page reload.</p>
  
  <p>I have searched all day for an answer but they all seem very complex for probably a simple 2 line function.</p>
