Example
This function can be used to pass the ID of selected item, for example:
# with select or collection_select helpers: { :onchange => remote_function(:url => { :action => 'do_smth' }, :with => "'id=' + $('the_id').value") } # and grab ID in controller action as usually: YourModel.find(params[:id])
