How do I get an array with all the elements selected?

ob_sn2.split('|') returns an array with the ids of the selected elements.
How do I get the selected ids at server side?
Add to your page a hidden element:
<input type='hidden' name='ob_selected_ids' id='ob_selected_ids' value=''>
And on the button that submits the page add:

Now on the server side, simply read the value from the field ob_selected_ids
and split it using | as separator
