Work differentiation between CodeIgniter / jQuery - best practice

Yuk, don't output a js array from php. Just get CI to output the semantically correct markup with the items selected. If you can't so this because your 'selected' items are list items instead of, say, checkboxes, then you're not doing it right Progressive enhancement: start with markup that actually works without JS. A nested lists of checkboxes for example inside a form that POSTs data to a CI controller. Then use jquery to add the bells and whistles.
