Hi,
Ajax.Updater is for updating the contents of an element with the
result of the request. I don't know what you mean by "...return 3 or
4 values to this page" unless you mean you want to update three or
four different elements with the result of a single call.
If that's what you want to do, you'll want to use Ajax.Request
instead, return some structured information (perhaps JSON-formatted
data), and use the onSuccess handler to update the elements with the
structured information. For example, your call might return an object
in JSON format like this:
{
updates: {
'header': '<h1>This is the HTML content for the header div</
h1>',
'body': '<p>This is is the content for the body div</p>',
'footer': 'This is the content for the footer div.'
}
}
...where 'header', 'body', and 'footer' are the IDs of the elements
you want to update. Your onSuccess handler would look something like
this:
function handleRequestSuccess(transport)
{
var updates;
if (transport.responseJSON && transport.responseJSON.updates)
{
updates = transport.responseJSON.updates;
for (target in updates)
{
$(target).update(updates[target]);
}
}
else
{
handleRequestFailure(transport);
}
}
FWIW.
