Hi,
`update` isn't a global symbol, you either need `Element.update` or an
element instance on which you call `.update`, e.g.:
var id = "foo";
Element.update(id, "<p>Hi there</p>");
// -or-
$(id).update("<p>Hi there</p>");
(In the latter case, it doesn't have to be looked up by ID, as long as
you eventually get an extended instance of an element. Could be $$
('td.foo')[0] or any other way of getting a specific instance.)
More here:
http://api.prototypejs.org/dom/element/update/
Unless you mean Ajax.Updater, which does an Ajax call and then calls
#update behind the scenes, which is something totally different:
http://api.prototypejs.org/ajax/ajax/updater/
I'm afraid I don't immediately understand what the line in question
does, so I can't give an edited example of it. But hopefully the above
helps figure it out.
HTH,
