* That would be the best way, yes. What code did you try?

* Hello RavanH, after close I need to add/remove class or show something like this:
* ```
afterClose: function(){$('body').append('Thanks for watching !
');}
```
* I try to add the code before closing fb_opts (around line 80)in easy-fancybox-
class.php
* ```
echo ', \'afterClose\': function(){$(\'body\').append(\'Thanks for watching !
\');}';
echo ' };
var easy_fancybox_handler = function(){';
```

* Sorry, easy-fancybox-class.php is not the correct file. You need to edit **easy-
fancybox-settings.php** instead. It holds a large array with all the default
options. Find (for example) the Youtube array which starts with:
* ```
'YouTube' => array(
'title' => __('YouTube','easy-fancybox'),
'input' => 'multiple',
'options' => array(
'intro' => array (
...
```
* Now add an extra array key right between that `'options' => array` and the following`'
intro' => array` like:
* ```
'onClosed' => array (
'noquotes' => true,
'default' => 'function() { $("body").append("Thanks for watching !
"); }'
),
```
* (do not forget that comma at the end there)
* Notes:
1. Please be aware that after the next plugin update, your modification
will be gone! 2. You’ll have to do this for every media type if you want same(
or similar) messages for all.

* Replace the `$("body")` with `jQuery("body")` and it should start working 🙂
