WP Alchemy MediaAccess.php hack to extract attachment ID

/////////////////////////////////////////////////////////////////////////////////
// Added by Dameian on 4/11/2011 to allow for extraction of the attachment's ID
// and population of a preview area.

// Isolate the attachment's ID
var mediaID = html.match(/wp-image-(.*)"/i);
mediaID = (mediaID && mediaID[1]) ? mediaID[1] : '' ;

// Pass the attachment ID to a hidden field with ID #media_id
$(wpalchemy_mediafield_selector).closest('.wpa_group').find('#media_id').val(mediaID);

// Send a preview thumb to a preview area
$(wpalchemy_mediafield_selector).closest('.wpa_group').find('.preview').html(html);

// Maybe make our media ID global and available to things like AJAX?
// WPAlchemyMediaID = mediaID;
