This example:

update_page do page page.insert_html :bottom, 'list', "<li>#{@item.name}</li>" page.visual_effect :highlight, 'list' page.hide 'status-indicator', 'cancel-link' end

generates the following JavaScript:

new Insertion.Bottom("list", "<li>Some item</li>"); new Effect.Highlight("list"); ["status-indicator", "cancel-link"].each(Element.hide);
